timely.  The Managing General Partners have committed to support the
Partnership's working capital requirements through short-term advances as

for operating expenses of $492,197 in 1999.  In addition, $32,365 was paid
to the Individual General Partners as compensation for their services.
Other operating expenses of $284,358 and interest expense of $4,280 were
paid and interest income of $16,155 was received.

During the nine months ended September 30, 1999, the Partnership funded
equity investments of $698,868 primarily to portfolio companies in the
communications, information technology and medical/biotechnology industries
and issued $183,333 in notes receivable to portfolio companies in the
environmental industry.  Proceeds from the sales of equity investments were
$347,267 and repayments of notes receivable were $198,844.  At September
30, 1999, the Partnership's unfunded commitments totaled $691,870.

The Partnership has a borrowing account with a financial institution.  At
September 30, 1999, the borrowing capacity of this account, which
fluctuates based on collateral value, was $529,042 and the outstanding
balance was $82,291; as of November 9, 1999, the borrowing capacity was
$538,506 and the outstanding balance was $241,444.  The Partnership's
investments in Adept Technology, Inc., Inhale Therapeutic Systems, Inc.,
Hybridon, Inc. and Rogue Ware Software, Inc. are pledged as collateral.

Cash and cash equivalents at September 30, 1999, were $16,895.  Future
proceeds from investment sales and future short-term borrowings along with
Managing General Partner support are expected to be adequate to fund
Partnership operations through the next twelve months.

Results of Operations
---------------------

    Current quarter compared to corresponding quarter in the preceding year
    -----------------------------------------------------------------------

Net loss was $1,792,716 for the quarter ended September 30, 1999, compared
to net loss of $2,448,457 during the same period in 1998.  The change was
primarily due to an increase of $1,205,285 in the net unrealized fair value
of equity investments and a $203,109 decrease in operating expenses,
partially offset by a $744,173 increase in realized losses from equity
sales.

During the quarter ended September 30, 1999, the decrease in equity
investment fair value of $1,016,111 was primarily attributable to a
decrease in a portfolio company in the environmental industry, partially
offset by increases in portfolio companies in the medical/biotechnology
industry.  During the same period in 1998, the decrease in fair value of
equity investments of $2,221,396 was primarily attributable to a decrease
in a portfolio company in the environmental industry.

Total operating expenses were $270,539 and $473,648 for the quarters ended
September 30, 1999 and 1998, respectively.  The decrease is primarily
attributable to decreased investment monitoring activity and administrative
overhead.

Realized losses from equity sales totaled $457,010 in the quarter ended
September 30, 1999 compared to a gain of $287,163 for the same period in
1998.  The 1999 loss relates to the sale of the Partnership's investments
in Naiad Technologies, Inc., CV Therapeutics, Inc. and Avalon Imaging, Inc.

Given the inherent risk associated with the business of the Partnership,
the future performance of the portfolio company investments may
significantly impact future operations.

    Current nine months compared to corresponding nine months in the
    --------------------------------------------------------------
    preceding year
    --------------

Net loss was $1,669,124 for the nine months ended September 30, 1999,
compared to net loss of $536,628 during the same period in 1998. The change
was primarily due to a decrease of $858,020 in the net unrealized fair
value of equity investments and an increase of $665,876 in realized losses
from equity sales, partially offset by a $287,328 decrease in operating
expenses.

During the nine months ended September 30, 1999, the decrease in equity
investment fair value of $327,663 was mainly attributable to portfolio
companies in the environmental and microelectronics industries, partially
offset by increases in the communications and medical/biotechnology
industries.  During the same period in 1998, the increase of $530,357 was
primarily attributable to a portfolio company in the environmental
industry.

Realized losses from equity sales totaled $487,474 for the nine months
ended September 30, 1999 as compared to a gain of $178,402 for the same
period in 1998.  The 1999 loss primarily relates to the sale of the
Partnership's investments in Naiad Technologies, Inc., CV Therapeutics,
Inc. and Avalon Imaging, Inc.

Total operating expenses were $854,712 and $1,142,040 for the nine months
ended September 30, 1999 and 1998, respectively.  The decrease is
attributable to decreased investment monitoring activities, administrative
overhead and computer expenses.

YEAR 2000
---------

Widespread use of computer programs that use two digits rather than four to
store, calculate, and display year values in dates may cause computer
systems to malfunction in the year 2000, resulting in significant business
delays and disruptions.

    The Partnership's State of Readiness
    ------------------------------------

Computer services are provided to the Partnership by its Managing General
Partner, Technology Funding Inc. ("TFI").  For several years, TFI has
sought to use Year 2000 compliant storage formats and algorithms in its
internally-developed and maintained systems.  TFI has also completed
initial evaluations of computer systems, software, and embedded
technologies.  Those evaluations confirmed that certain components of its
network server hardware and operating systems, voice mail system, e-mail
system, and accounting software may have Year 2000 compliance issues.
These resources and several less-critical components of the systems
environment were all scheduled as part of normal maintenance and
replacement cycles to be replaced or upgraded as Year 2000 compatible
components became available from vendors during 1998 and 1999.  That
program remains on schedule to provide Year 2000 capable systems timely
without significant expenditures or disruption of Partnership operations.
TFI has implemented and tested Year 2000 capable versions of all its
mission-critical systems.  However, the risk remains that TFI may not be
able to verify whether Year 2000 compatibility claims by vendors are
accurate, or whether changes undertaken to achieve Year 2000 compatibility
will create other undetected problems in associated systems.  Therefore,
TFI anticipates that Year 2000 compliance testing and maintenance of these
systems will continue as needed into the first quarter of 2000.

As part of Year 2000 evaluation, TFI has also assembled a database listing
its significant suppliers to assess the extent to which it needs to prepare
for any of those parties' potential failure to remediate their Year 2000
compliance issues.  TFI reviewed public Year 2000 statements of those
suppliers and sent questionnaires to vendors whose public statements were
not adequate for assessment.  All mission-critical vendors have responded
that they expect to be Year 2000 compliant barring any unforeseen
circumstances.  TFI will continue to monitor its significant suppliers as
part of its Year 2000 evaluation.  However, there can be no guarantee that
the systems of other companies on which TFI relies will be timely
converted, or that failure to convert will not have a material adverse
effect on the Partnership and its operations.  TFI is also working with the
Partnership's portfolio companies to determine the extent to which their
operations are vulnerable to Year 2000 issues, and maintaining their
responses in the vendor database.  There can be no guarantee that the
systems of portfolio companies in which the Partnership has invested will
be timely converted, or that their failure to convert will not have a
material adverse effect on the Partnership.

    The Cost to Address Year 2000 Issues
    ------------------------------------

Expenditures in 1999 to date related to Year 2000 issues were not material
to the Partnership's financial statements.  TFI expects that additional
expenditures for Year 2000 compliance will not be material to the
Partnership.

    The Risks Associated with Year 2000 Issues
    ------------------------------------------

Any failure by the portfolio companies in which the Partnership has
invested, or by those portfolio companies' key suppliers or customers, to
anticipate and avoid Year 2000 related problems at reasonable cost could
have a material adverse effect on the value of and/or the timing of
realization of value from the Partnership's investments.  If TFI's Year
2000 compliance issues have not been resolved correctly, internal system
failures or miscalculations could cause a temporary inability to process
transactions, loss of ability to send or receive e-mail and voice mail
messages, or disruptions in other normal business activities.
Additionally, failure of third parties on whom TFI relies to remediate
their Year 2000 issues timely could result in disruptions in the
Partnership's relationship with its financial institutions, temporary
disruptions in processing transactions, unanticipated costs, and problems
related to the Partnership's daily operations.  While TFI continues to
address its internal Year 2000 issues, the overall risks associated with
the Year 2000 issue remain difficult to describe and quantify.  There can
be no guarantee that the Year 2000 issue will not have a material adverse
effect on the Partnership and its operations.

    TFI's Contingency Plan
    ----------------------

As part of its normal efforts to assure business continuation in the event
of natural disasters, systems failures, or other disruptions, TFI has
prepared contingency plans including an extensive Year 2000 contingency
plan.  Taken together with TFI's Year 2000 remediation plan, it identifies
potential points of failure, approaches to correcting known Year 2000
problems, dates by which the preferred corrections are anticipated to be
made and tested, and alternative approaches if the corrections are not
completed timely or are later found to be inadequate.  Although backup
systems and contingency approaches have been identified for most systems
and vendor dependencies, there remain some systems for which no good
alternative exists, and there may be some problems that prove more
intractable than currently anticipated.
