                                   (Unaudited)


NOTE 1 - ORGANIZATION:

Datronic Equipment Income Fund XX, L.P., a Delaware Limited Partnership (the
"Partnership"), was formed on April 30, 1991 for the purpose of acquiring and
leasing both high- and low-technology equipment. The offering of limited
partnership units terminated on May 1, 1992. See Notes 5, 8 and 10 to the
Partnership's financial statements included in the 1998 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 1998 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
1998 Form 10-K.

NOTE 3 - LIMITED PARTNERSHIP DISTRIBUTIONS:

In early April 1999, the Partnership made a cash distribution to Limited
Partners who were owners of record on December 31, 1998. This distribution
consisted of two components: (i) the net proceeds from the Price Waterhouse and
Weiss & Company legal actions ($15,000 and $202,000 for Liquidating and
Continuing Limited Partners, respectively), and (ii) residual cash resulting
from the net cash flows of the Partnership ($94,000 and $2,116,000 for
Liquidating and Continuing Limited Partners, respectively). The portion of the
distribution attributable to legal action proceeds was allocated to each Limited
Partner based on the number of units held at the rate of $2.87 per unit. See
Note 8 to the Partnership's financial statements included in the 1998 Form 10-K.
Pursuant to the Partnership Agreement, residual cash was allocated to each
Limited Partner based on their proportionate share of total partners' capital
attributable to their Class.

NOTE 4 - RESIDUAL INTEREST IN CRCA:

Residual interest in CRCA represents the Partnership's fully reserved 35% (65%
for Fund XVIII) interest in the remaining assets of Computer Rental Corp. of
America, Inc. (CRCA). These assets consisted of a

$4.2 million subordinated note receivable from Personal Computer Rental
Corporation (PRC) and $136,000 of cash. See Note 4 to the financial statements
included in the 1998 Form 10-K. In early April, 1999, CRCA sold the note to
PCR's senior secured creditor for $250,000. The Partnership's share ($87,500) of
the proceeds has been credited to the provision for lease losses. The
Partnership's 35% share of any residual cash that may remain after payment of
expenses will also be credited to the provision for lease losses when paid to
the Partnership.

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, 1998
through June 30, 1999. The discussion and analysis of results of operations is
for the three and six month periods ended June 30, 1999 as compared to the
corresponding periods in 1998. Any capitalized term not defined herein has been
defined or discussed in the Partnership's 1998 Form 10-K.

Liquidity and Capital Resources

During the six months ended June 30, 1999, Partnership assets continued to be
converted to cash in order to pay Partnership operating expenses and to provide
for the ultimate liquidation of the Partnership. During the six months ended
June 30, 1999, Partnership cash and cash equivalents decreased by $2,338,000 to
$2,202,000 at June 30, 1999 from $4,540,000 at December 31, 1998. This decrease
is primarily due to the distribution paid to Limited Partners of $2,426,000 (see
below) and by cash used in operations of $199,000, partially offset by cash
receipts from collections on leases of $199,000 and $87,000 from the sale of a
CRCA note receivable.

In early April 1999, the Partnership made a cash distribution to Limited
Partners who were owners of record on December 31, 1998. This distribution
consisted of two components: (i) the net proceeds from the Price Waterhouse and
Weiss & Company legal actions ($15,000 and $202,000 for Liquidating and
Continuing Limited Partners, respectively), and (ii) residual cash resulting
from the net cash flows of the Partnership ($94,000 and $2,116,000 for
Liquidating and Continuing Limited Partners, respectively). The portion of the
distribution attributable to legal action proceeds was allocated to each Limited
Partner based on the number of units held at the rate of $2.87 per unit. See
Note 8 to the Partnership's financial statements included in the 1998 Form 10-K.
Pursuant to the Partnership Agreement, residual cash was allocated to each
Limited Partner based on their proportionate share of total partners' capital
attributable to their Class.

The Partnership's sources of future liquidity are expected to come from
cash-on-hand, cash receipts from leases owned by the Partnership and the
disposition of the remaining Diverted Assets (consisting primarily of an office
building in Schaumburg, Illinois). The lease portfolio is scheduled to be fully
liquidated by March 2001. The general partner expects that the building will be
sold during the second half of 1999 or 2000 and the proceeds included in the
next distribution to the Limited Partners sometime during 2000. After all assets
are disposed of and the proceeds distributed to the Limited Partners, the
Partnership will be required to file final reports with the Securities and
Exchange Commission and the Internal Revenue

Service. The general partner expects this to occur sometime during the year
2001.


Results of Operations

The Partnership had net losses of $30,000 and $98,000 for the three and six
months ended June 30, 1999 in the aggregate for all classes of partners. This
compares to net losses of $189,000 and $104,000 for the three and six months
ended June 30, 1998. 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, 1999 and 1998 include the
following:

Lease income:
Since January 1997, the Partnership has been in its Liquidating 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. This trend will continue as the Partnership liquidates its
remaining leases.

Interest income:
Interest income includes earnings on invested cash balances. Interest income for
1999 was lower than 1998 because of lower average invested cash balances and
interest rates.

General Partner's expense reimbursement:
General Partner's expense reimbursement includes payments to LRC for expenses it
incurred as general partner. These expenses include expenses incurred by LRC in
its management of the day-to-day operations of the Partnership.

Professional fees:
Professional fees for the three and six months ended June 30, 1999 reflect a
decreasing level of professional services required as a result of the decrease
in the Partnership's lease portfolio and related activities. Included in the
1998 amount are fees paid in connection with the litigation against the
Partnership's former accountants.

Credit for lease losses:
This credit reflects recovery of previously reserved balances. The 1999 credit
includes the Partnership's share ($87,500) of a $250,000 recovery against its
residual interest in CRCA that resulted from the sale of a note receivable. See
Note 4 to the Partnership's financial statements included in Item 1. The 1998
credit includes a $207,000 CRCA-related recovery from the collection of another
note receivable. See Note 4 to the Partnership's financial statements included
in the 1998 Form 10-K.
