                    DATRONIC EQUIPMENT INCOME FUND XIX, L.P.
                          NOTES TO FINANCIAL STATEMENTS
                                  June 30, 1998
                                   (Unaudited)

NOTE 1 - ORGANIZATION:

Datronic Equipment Income Fund XIX, L.P., a Delaware Limited Partnership (the
"Partnership"), was formed on December 22, 1989 for the purpose of acquiring and
leasing both high-and low-technology equipment. See Notes 5, 8, and 10 to the
Partnership's financial statements included in the 1997 Form 10-K for a
discussion of the alleged diversion of Partnership assets in 1991 and 1992 and
the subsequent litigation and settlement, change in general partner, new classes
of limited partners established and amendments to the Partnership Agreement
which occurred.

NOTE 2 - BASIS OF FINANCIAL STATEMENTS:

The accompanying financial statements should be read in conjunction with the
Partnership's financial statements included in the 1997 Form 10-K. The financial
information furnished herein is unaudited but in the opinion of Management
includes all adjustments necessary (all of which are normal recurring
adjustments) for a fair presentation of financial condition and results of
operations. See Note 2 to the Partnership's financial statements included in the
1997 Form 10-K.

NOTE 3 - LIMITED PARTNERSHIP DISTRIBUTIONS:

Distributions to Liquidating Limited Partners were suspended after payment of
the October 1, 1995 distribution. Distributions to Continuing Limited Partners
were suspended after payment of the January 1, 1998 distribution.

NOTE 4 - SETTLEMENT OF LITIGATION:

On May 5, 1998, Lease Resolution Corporation (LRC), on behalf of Datronic
Equipment Income Funds XVI, XVII, XVIII, XIX, XX and Datronic Finance Income
Fund I, reached an agreement to settle all claims of the aforementioned
partnerships against Weiss & Co. ("Settlement Agreement"). (See Note 8 to the
financial statements included in the Partnership's 1997 Form 10-K). The
Settlement Agreement is contingent upon subsequent approval by the United States
District Court for the Northern District of Illinois, Eastern Division (the
"District Court") dismissing Weiss & Co. as a party defendant. Pursuant to the
terms of the Settlement Agreement, Weiss & Co. has agreed to pay LRC, on behalf
of the aforementioned partnerships, $2.4 million. LRC expects to determine the
appropriate allocation of these proceeds among the Partnerships, net of
contingent attorneys fees of $600,000, during the third quarter after
considering all relevant factors associated with the Settlement. Weiss & Co. has
transferred $2.4 million to an escrow account; this amount will be transferred
to LRC no later than 30 days following the

District Court entering an order of dismissal of Weiss & Co. The District Court
has scheduled a hearing for August 19, 1998 to entertain the motion of dismissal
of Weiss & Co. as a party defendant.

On June 10, 1998, a verdict was rendered finding Price Waterhouse liable for
negligence, but not guilty of breach of contract. On July 20, LRC and Price
Waterhouse both filed post trial motions requesting relief from the Court.  The
Court is not expected to rule on these motions for several months.

PART I

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

The following discussion and analysis of liquidity and capital resources covers
material changes in the Partnership's financial condition from December 31, 1997
through June 30, 1998. The discussion and analysis of results of operations is
for the three and six month periods ended June 30, 1998 as compared to the
corresponding periods in 1997.

Liquidity and Capital Resources

During the six months ended June 30, 1998, Partnership assets continued to be
converted to cash in order to pay Partnership operating expenses, liquidate
Partnership liabilities, make distributions to limited partners and provide for
the ultimate liquidation of the Partnership.

During the six months ended June 30, 1998, the Partnership's cash and cash
equivalents decreased by $359,000 to $2,715,000 at June 30, 1998 from $3,074,000
at December 31, 1997. This decrease is primarily due to the use of cash in
operations of $940,000 and distributions to partners of $500,000, partially
offset by cash receipts from collections on leases of $1,066,000 and from
commercial lease paper of $14,000.

The Partnership's sources of liquidity on both a long-term and short-term basis
are expected to come principally from cash-on-hand and cash receipts from leases
owned by the Partnership. The lease portfolio is scheduled to be substantially
run out by the end of 2000, unless it is determined that it is in the
Partnership's best interest to dispose of the remaining portfolio earlier
through a bulk sale. In addition, the Partnership's sources of liquidity on a
long-term basis include proceeds from the sale of Diverted and other assets.
Management believes that its sources of liquidity in the short and long-term are
sufficient to meet its operating cash requirements, provide for ongoing pursuit
of litigation, and an orderly liquidation of the Partnership.

The continued operation and eventual liquidation of the Partnership involves
numerous complex issues which have to be resolved. These issues relate to the
timing and the amount to be realized from the liquidation of lease-related
assets, Diverted and other assets, Datronic assets, litigation and the
liquidation of the other Datronic Partnerships. These issues make it difficult
to predict the time and costs necessary to operate and liquidate the Partnership
in an orderly manner. As a result of these uncertainties, it is unlikely that
any significant additional distributions will be made until all remaining assets
are liquidated and the pending litigation is resolved. The amount of future
distributions, if any, to the Limited Partners, in all likelihood, will be
significantly less than the amount of partners' equity reflected in the June 30,
1998 balance sheets (see Partnership's financial statements included in Item 1).

Results of Operations

The Partnership had a net loss of $491,000 and $854,000 for the three and six
months ended June 30, 1998, respectively, in the aggregate for all classes of
partners. This compares to an aggregate net loss of $229,000 and $409,000 for
the same periods in 1997, respectively. Differences in operating results between
Liquidating and Continuing Limited Partners are attributable to lease income,
acquisition costs, and expenses associated with new lease investments made since
the March 4, 1993 Settlement. Liquidating Limited Partners do not participate in
these post Settlement activities. Significant factors affecting overall
operating results for the three and six month periods ended June 30, 1998 as
compared to the same periods in 1997 include the following:

Lease income:
Since August 1996, the Partnership has been in its Liquidation Phase which
prohibits investing in any new leases. Accordingly, the lease portfolio has
continued to decrease as collections are made, resulting in a continued decline
in lease income for the three and six months ended June 30, 1998 as compared to
the corresponding periods in 1997.

Interest income:
Interest income decreased for the three and six months ended June 30, 1998 as
compared to the corresponding periods in 1997 as a result of decreased invested
cash balances.

General Partner's expense reimbursement:
The decrease for the three and six month periods ended June 30, 1998 is
primarily due to changes in the premium payments for D&O insurance, relocation
costs and reductions in staff and related costs. Through the first quarter 1997,
D&O insurance premiums were paid on an annual basis; however, in September 1997
a one-time premium was paid that extended coverage through the ultimate
liquidation date of the Partnership. Included in the second quarter 1997 is a
one-time charge for relocating staff to reduced office space.

Professional fees:
The 1998 increase reflects fees paid in connection with the ongoing litigation
against the Partnership's former accountants. As of August 14, 1998 the
litigation process continues. This increase is partially offset by the
decreasing level of professional services required in such areas as collections,
consulting and auditing. These decreases are the result of the decrease in the
Partnership's lease portfolio and related activities.

Credit for lease losses:
This credit primarily reflects collections on previously reserved balances.
