EXHIBIT 10.9
                                      NOTE

$450,000                                                  April 7, 2004
                                                          Minneapolis, Minnesota

         For value received, the undersigned, Dotronix, Inc., a Minnesota
corporation ("Maker"), hereby promises to pay to the order of Terry L. Myhre,
his heirs and assigns ("Lender") at any place designated at any time in writing
by the holder hereof, in lawful money of the United States of America, the
principal sum of Four Hundred Fifty Thousand and 00/100 dollars ($450,000) or so
much thereof as has been advanced and remains outstanding under a letter loan
agreement dated the date hereof between Maker and Lender (the "Loan Agreement"),
together with interest (calculated on the basis of actual days elapsed in a
360-day year) on the unpaid principal hereof, from the date immediately
available funds representing the principal sum are credited to the account of
the Maker until this Note is fully paid, at a rate equal to five percent (5%)
per annum. As used herein, "due date" means April 7, 2005.

         Interest shall be payable monthly, on the last day of each month
commencing April 30, 2004, and on the last day of each succeeding month
thereafter until this Note is paid in full on or prior to the due date.

         This Note shall be payable in lawful money of the United States of
America in immediately available funds. All payments on this Note shall be
applied to the payment of accrued interest before being applied to the payment
of principal. Any payment which is required to be made on a day which is not a
banking business day shall be payable on the next succeeding banking business
day and such additional time shall be included in the computation of interest.
The principal amount of this Note may be prepaid in whole or in part at any time
without prior notice, premium, or penalty so long as such prepayment is
accompanied by payment of all interest accrued.

As of the due date, the Lender may convert all (but not part) of the entire
principal amount of and accrued interest on this Note into shares of common
stock of the Company ("Shares"). The number of Shares into which the Note may be
converted shall be determined by dividing (i) the entire outstanding principal
amount under this Note as of the due date plus all unpaid accrued interest, by
(ii) $1.50. In order to exercise the right of optional conversion, the Lender
shall give written notice of such conversion to the Maker no later than the date
that is 60 days prior to the due date.

         The occurrence of any one or more of the following events shall
constitute an "Event of Default": (a) the Maker shall fail to make when due,
whether by acceleration or otherwise, any payment

                                       52
<PAGE>

of principal of, or interest on, the Note and such failure shall continue for a
period of 5 business days after notice thereof; or (b) any representation or
warranty made by the Maker in the Loan Agreement shall prove to have been false
or misleading in any material respect on the date as of which the facts set
forth are stated; or (c) the Maker shall fail to comply with any agreement in
the Loan Agreement, provided, however, that the occurrence of any event that
would otherwise constitute an Event of Default under subsections (b) or (c)
shall not constitute an Event of Default until such default shall remain uncured
for a period of 30 days after the Maker's notice thereof, so long as (i) the
Maker promptly notifies the Lender thereof, (ii) such default can reasonably be
remedied in such period, and (iii) the Maker is proceeding with best
commercially reasonably efforts to cure such failure as soon as possible.

         If any Event of Default shall occur and be continuing, the Lender may
declare that the outstanding unpaid principal balance of the Note, the accrued
and unpaid interest thereon and all other obligations of the Maker to the Lender
under this Note to be forthwith due and payable, whereupon the Note, all accrued
and unpaid interest thereon and all such obligations shall immediately become
due and payable, in each case without further demand or notice of any kind, all
of which are hereby expressly waived, anything in this Note to the contrary
notwithstanding. In addition, upon any Event of Default and so long as such
Event of Default continues, the Lender may exercise all rights and remedies
under any other instrument, document or agreement between the Maker and the
Lender, and enforce all rights and remedies under any applicable law.

         The Maker agrees to reimburse the Lender upon demand for all reasonable
attorney's fees and expenses paid or incurred by the Lender in connection with
the collection and enforcement of this Note.

         Maker waives presentment, notice of dishonor, protest, and notice of
protest, and any or all other notices or demands (other than demand for payment)
in connection with the delivery, acceptance, performance, default, endorsement,
or guaranty of this Note. The liability of Maker hereunder shall be
unconditional and shall not be in any manner affected by any indulgence
whatsoever granted or consented to by the holder hereof, including but not
limited to any extension of time, renewal, waiver, or other modification. Any
failure of the holder to exercise any right hereunder shall not be construed as
a waiver of the right to exercise the same or any other right at any time and
from time to time thereafter. Lender or any holder may accept late payments, or
partial payments, even though marked "payment in full" or containing words of
similar import or other conditions, without waiving any of its rights. No
amendment, modification, or waiver of any provision of this Note nor consent to
any departure by Maker therefrom shall be effective, irrespective of any course
of dealing, unless the same shall be in writing and signed by Lender, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given. This Note cannot be changed or terminated
orally or by estoppel or waiver or by any alleged oral modification regardless
of any claimed partial performance referable thereto.

         Any notice from Lender to Maker shall be deemed given when delivered to
Maker by hand or when deposited in the U.S. mail and addressed to Maker at the
last address of Maker appearing on Lender's records.

         This Note replaces and supersedes the demand notes made by Maker in
favor of Lender in the principal amount of $30,000 each dated September 4, 2003,
November 19, 2003 and January 7, 2004 for an aggregate principal amount of
$90,000, and the demand note made by Maker to Lender in the principal amount of
$45,000 dated January 21, 2004.

         This Note shall be governed by and construed in accordance with the
laws of the State of Minnesota applicable to instruments made and to be
performed wholly within that state. If any

                                       53
<PAGE>

provision of this Note is held to be illegal or unenforceable for any reason
whatsoever, such illegality or unenforceability shall not affect the validity of
any other provision hereof.

         MAKER AGREES THAT ANY ACTION, SUIT, OR PROCEEDING IN RESPECT OF OR
ARISING OUT OF THIS NOTE MAY BE INITIATED AND PROSECUTED IN THE STATE OR FEDERAL
COURTS, AS THE CASE MAY BE, LOCATED IN HENNEPIN COUNTY, MINNESOTA. MAKER
CONSENTS TO AND SUBMITS TO THE EXERCISE OF JURISDICTION OVER ITS PERSON BY ANY
SUCH COURT HAVING JURISDICTION OVER THE SUBJECT MATTER, WAIVES PERSONAL SERVICE
OF ANY AND ALL PROCESS UPON IT, AND CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE
MADE BY REGISTERED MAIL DIRECTED TO MAKER AT ITS ADDRESS SET FORTH BELOW OR TO
ANY OTHER ADDRESS AS MAY APPEAR IN LENDER'S RECORDS AS THE ADDRESS OF MAKER.

         IN ANY ACTION, SUIT OR PROCEEDING IN RESPECT OF OR ARISING OUT OF THIS
NOTE, LENDER AND MAKER BOTH WAIVE TRIAL BY JURY, AND MAKER ALSO WAIVES (i) THE
RIGHT TO INTERPOSE ANY SETOFF OR COUNTERCLAIM OF ANY NATURE OR DESCRIPTION; (ii)
ANY OBJECTION BASED ON FORUM NON CONVENIENS OR VENUE; AND (iii) ANY CLAIM FOR
CONSEQUENTIAL, PUNITIVE, OR SPECIAL DAMAGES.

                                       54EXHIBIT 10.10

         THIS WARRANT AND THE SECURITIES REPRESENTED HEREBY AND ISSUABLE
PURSUANT HERETO HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "SECURITIES ACT") AND MAY NOT BE OFFERED OR SOLD, TRANSFERRED,
PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT IN A TRANSACTION THAT IS
EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND FROM THE
REGISTRATION AND QUALIFICATION REQUIREMENTS OF APPLICABLE STATE SECURITIES LAWS,
OR IN A TRANSACTION EFFECTED PURSUANT TO SUCH REGISTRATION AND QUALIFICATION.

                                 DOTRONIX, INC.
                            (A MINNESOTA CORPORATION)

                       WARRANT TO PURCHASE 100,000 SHARES
                   OF COMMON STOCK, PAR VALUE $0.05 PER SHARE

         THIS CERTIFIES THAT, for value received, Terry L. Myhre or his
permitted transferees (the "Holder") is entitled to subscribe for and purchase
100,000 shares (the "Shares") of fully paid and nonassessable common stock, par
value $0.05 per share ("Common Stock") of Dotronix, Inc., a Minnesota
corporation (the "Company") at the Warrant Exercise Price as determined in
accordance with the terms hereof, which shall initially be equal to $0.10 per
share, subject to the provisions and upon the terms and conditions hereinafter
set forth.

         1. Term. The purchase right represented by this Warrant is exercisable,
in whole or in part, at any time and from time to time commencing on the date
hereof and ending at the close of business on April 7, 2011.

         2. Method of Exercise; Payment; Issuance of New Warrant. Subject to
Paragraph 1 hereof, the purchase right represented by this Warrant may be
exercised by the Holder, in whole or in part and from time to time, by the
surrender of this Warrant (with the notice of exercise form attached hereto as
Exhibit 1 duly executed) at the principal office of the Company and by the
payment to the Company, by check, of an amount equal to the then applicable
Warrant Exercise Price (as defined in Paragraph 4) per share multiplied times
the number of Shares then being purchased. The person or persons in whose
name(s) any certificate(s) representing the Shares shall be issuable upon
exercise of this Warrant shall be deemed to have become the holder(s) of record
of, and shall be treated for all purposes as the record holder(s) of, the shares
represented thereby (and such shares shall be deemed to have been issued)
immediately prior to the close of business on the date or dates upon which this
Warrant is exercised. In the event of any exercise of the rights represented by
this Warrant, certificates for the shares of stock so purchased shall be
delivered to the Holder as soon as is reasonably practicable and, unless this
Warrant has been fully exercised or expired, a new Warrant representing the
portion of the Shares, if any, with respect to which this Warrant shall not then
have been exercised shall also be issued to the Holder as soon as is reasonably
practicable.

         3. Stock Fully Paid; Reservation of Shares. The Company agrees that all
Shares issued upon the exercise of the rights represented by this Warrant will,
upon issuance, be fully paid and nonassessable, and free from all preemptive
rights, taxes, liens and charges with respect to the issue thereof; provided,
that the Company shall not be required to pay any withholding taxes with respect
to the issue of shares or any transfer taxes with respect to the issue of shares
in any name other than that of the registered holder hereof. During the period
within which the rights represented by this Warrant may be exercised, the
Company will at all times have authorized, and reserved for the purpose of
issuance upon exercise of the purchase rights evidenced by this Warrant, a
sufficient number of shares of its Common Stock to provide for the exercise of
the rights represented by this Warrant. The Company shall at all times take all
such action and obtain all such permits or orders as may be necessary to enable
the Company lawfully to issue such shares of Common Stock as duly and validly
issued, fully paid and nonassessable shares upon exercise in full of this
Warrant by Holder.

         4. Adjustment of Warrant Exercise Price and Number of Shares. The
number and kind of securities purchasable upon the exercise of this Warrant and
the Warrant Exercise Price shall be subject to adjustment from time to time upon
the occurrence of certain events as set forth in this Paragraph 4:

                  (a) If the Company at any time divides the outstanding shares
         of its Common Stock into a greater number of shares (whether pursuant
         to a stock split, stock dividend or otherwise), and conversely, if the
         outstanding shares of its Common Stock are combined into a smaller
         number of shares, the Warrant Exercise Price in effect immediately
         prior to such division or combination shall be proportionately adjusted
         to reflect the reduction or increase in the value of each such share of
         Common Stock.

                                       55
<PAGE>

                  (b) If any capital reorganization or reclassification of the
         capital stock of the Company, or consolidation or merger of the Company
         with another corporation, or the sale of all or substantially all of
         its assets to another corporation shall be effected in such a way that
         holders of the Company's Common Stock shall be entitled to receive
         stock, securities or assets with respect to or in exchange for such
         Common Stock, then, as a condition of such reorganization,
         reclassification, consolidation, merger or sale, the Holder shall
         thereafter have the right to purchase and receive upon the basis and
         upon the terms and conditions specified in this warrant and in lieu of
         the shares of the Common Stock of the Company immediately theretofore
         purchasable and receivable upon the exercise of the rights represented
         hereby, such shares of stock, other securities or assets as would have
         been issued or delivered to the Holder if Holder had exercised this
         Warrant and had received such shares of Common Stock immediately prior
         to such reorganization, reclassification, consolidation, merger or
         sale. The Company shall not effect any such consolidation, merger or
         sale unless prior to the consummation thereof the successor corporation
         (if other than the Company) resulting from such consolidation or merger
         or the corporation purchasing such assets shall assume by written
         instrument executed and mailed to the Holder at the last address of the
         Holder appearing on the books of the Company the obligation to deliver
         to the Holder such shares of stock, securities or assets as, in
         accordance with the foregoing provisions, the Holder may be entitled to
         purchase.

                  (c) Except as provided in paragraph (d) below, if and whenever
         the Company shall (i) issue or sell any shares of Common Stock for a
         consideration per share less than the Warrant Exercise Price in effect
         immediately prior to the time of such issuance or sale, (ii) issue or
         sell any warrants, options or other rights to acquire shares of Common
         Stock at a purchase price less than the Warrant Exercise Price in
         effect immediately prior to the time of such issuance or sale, or (iii)
         issue or sell any other securities that are convertible into shares of
         Common Stock for a purchase or exchange price less than the Warrant
         Exercise Price in effect immediately prior to the time of such issuance
         or sale, then, upon such issuance or sale, the Warrant Exercise Price
         shall be reduced to the price (calculated to the nearest cent)
         determined by dividing (A) an amount equal to the sum of (I) the number
         of shares of Common Stock outstanding immediately prior to such issue
         or sale multiplied by the then existing Warrant Exercise Price and (II)
         the consideration, if any, received by the Company upon such issue or
         sale plus the consideration to be received by the Company upon the
         exercise of such stock purchase rights by (B) an amount equal to the
         sum of (I) the number of shares of Common Stock outstanding immediately
         prior to such issue or sale and (II) the number of shares of Common
         Stock thus issued or sold or issuable or saleable upon the exercise of
         such purchase rights or the conversion of such convertible securities;
         PROVIDED, HOWEVER, that in the event that any such purchase right
         expires or is terminated prior to the exercise of this Warrant, the
         Warrant Exercise Price shall be recalculated by deleting such purchase
         right, and PROVIDED FURTHER, that if an adjustment is made to the
         Warrant Exercise Price as a result of the issuance or sale of any such
         purchase rights or convertible securities, no further adjustment shall
         be made to the Warrant Exercise Price at the time such purchase rights
         are exercised or convertible securities are converted.

                  (d) Notwithstanding the provisions of paragraph (c) above, no
         adjustment shall be made in the Warrant Exercise Price as a result of
         (i) the exercise of options or warrants to purchase Common Stock or
         other derivative securities exercisable for shares of Common Stock that
         are outstanding at the date of this Warrant; (ii) the exercise of the
         warrant to purchase 385,000 shares of Common Stock to be granted to the
         estate of William S. Sadler as of the date of this Warrant, (iii) the
         grant of options to purchase Common Stock or the grant of restricted
         stock and other similar equity-based compensation awards pursuant to
         stock option and incentive plans which have been approved by the
         Company's board of directors, or the exercise of such options

                                       56
<PAGE>

         or awards or (iv) the issuance of additional warrants in substantially
         the form of this Warrant pursuant to the Company's borrowing
         arrangements with Terry L. Myhre, or the exercise of such warrants.

                  (e) If the Company takes any other action, or if any other
         event occurs, which does not come within the scope of the provisions of
         paragraphs (a) through (c) above but which should result in an
         adjustment in the Warrant Exercise Price and/or the number of shares
         subject to this Warrant in order to fairly protect the purchase rights
         of the Holder, an appropriate adjustment in such purchase rights shall
         be made by the Company.

                  (f) Upon each adjustment of the Warrant Exercise Price, the
         Holder shall thereafter be entitled to purchase, at the Warrant
         Exercise Price resulting from such adjustment, the number of shares
         obtained by multiplying the Warrant Exercise Price in effect
         immediately prior to such adjustment by the number of shares
         purchasable pursuant hereto immediately prior to such adjustment and
         dividing the product thereof by the Warrant Exercise Price resulting
         from such adjustment.

                  (g) Upon any adjustment of the warrant exercise price, the
         Company shall give written notice thereof to the Holder stating the
         warrant exercise price resulting from such adjustment and the increase
         or decrease, if any, in the number of shares purchasable at such price
         upon the exercise of this warrant, setting forth in reasonable detail
         the method of calculation and the facts upon which such calculation is
         based.

         5. No Fractional Shares. No fractional shares of Common Stock will be
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor upon the basis of the
market price of such shares as of the close of business on the exercise date.

         6. No Privilege of Stock Ownership. Prior to the exercise of this
Warrant, the Holder shall not be entitled, by virtue of holding this Warrant, to
any rights of a stockholder of the Company, including (without limitation) the
right to vote or to receive dividends or other distributions.

         7. Transferability. This Warrant may not be offered or sold,
transferred, pledged, hypothecated or otherwise disposed of except in a
transaction that is exempt from the registration requirements of the Securities
Act and from the registration and qualification requirements of applicable state
securities laws, or in a transaction effected pursuant to such registration and
qualification.

         8. No Registration Rights; Legend. The Company is not obligated to
register this Warrant or any of the shares of Common Stock issuable hereunder
pursuant to the Securities Act of 1933 or any state securities laws. Any
certificates representing shares of Common Stock issued hereunder shall bear a
restrictive legend in such form and substance as counsel to the Company advises
the Company is required under applicable securities laws.

         9. Notices. Any notice, request or other document required or permitted
to be given or delivered to the Holder or the Company shall be delivered, or
shall be sent by certified or registered mail, postage prepaid, to the Holder at
its address as shown on the books of the Company or to the Company at the
