                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)


--------------------------------------------------------------------------------


1.   STOCKHOLDERS' EQUITY

     The Company has two active stock option plans.  The Nonemployee Directors'
     Stock Option Plan  provides for the grant of options to purchase up to
     320,000 common shares to outside directors of the Company.  Options are
     granted at the fair market value of the stock on the date of grant and vest
     over a four year period.  The maximum term of an option may not exceed six
     years.  Of this total, options to purchase 240,000 shares of common stock
     are outstanding and 80,000 shares remain available for grant.

     The 1992 Employees Stock Option Plan provides for the grant of options to
     purchase up to 800,000 common shares to key employees of the Company.
     Options are granted at the fair market value of the stock on the date of
     grant and vest over a four year period.  The maximum term of an option may
     not exceed six years.  Of this total, options to purchase 578,500 shares of
     common stock are outstanding and 114,250 shares remain available for grant.
     In addition, options to purchase 500,000 shares of common stock are
     outstanding under certain of the Company's predecessor stock option plans.



2.   FEDERAL INCOME TAX

     At of December 31, 1996, the Company had net operating loss carryforwards
     of approximately $12,185,000.  The carryforwards expire from 2001 to 2011.
     The Company also has investment tax credit as well as research and
     development tax credit carryforwards of $290,000 and $752,000,
     respectively, available to offset future income tax liabilities through
     2001.  Although the Company has adopted the Statement of Financial
     Accounting Standards No. 109 Accounting for Income Taxes, there is no tax
     asset recognized for the net operating loss carryforwards and tax credits
     due to the Company's loss history and therefore uncertainty regarding
     future taxable income.   Due to an expected annual effective tax rate of
     zero, the Company recognized no income tax expense in the first or second
     quarter of fiscal 1997 or 1996.





The unaudited Interim Financial Statements reflect all adjustments which are, in
the opinion of management, necessary to a fair statement of the results for the
interim periods presented.  The results of operations for the period ending
December 31, 1996, are not necessarily indicative of operating results to be
expected for the full year.  These interim condensed financial statements should
be read in conjunction with the June 30, 1996, audited financial statements.


                                                                               6

PART I.   FINANCIAL INFORMATION

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

This Quarterly Report on Form 10-QSB may contain forward-looking statements that
involve risks and uncertainties.  These statements may differ materially from
actual future events or results which could cause actual results to differ from
those forward looking statements contained in this Form 10-QSB.


RESULTS OF OPERATIONS

THREE MONTHS ENDED DECEMBER 31, 1996 VERSUS 1995

Sales for the second quarter for fiscal 1997 were $2,640,000 which represented
an 11% increase over the $2,374,000 for the same period of last year.  This
increase was due to increased sales in the CPE (Customer Premise Equipment)
product line.  Gross margin percentage decreased from 47% in the second quarter
of fiscal 1996 to 40% for  the same period in the current year.  The majority of
the decrease in gross margin percentage is due to two large custom orders which
were given special volume pricing.  The remaining decrease in gross margin
percentage is due to product mix variations which are normal occurrences for the
Company.

The reduction in gross margin percentage, netted with a 5% decrease in operating
expenses over the same period last year, resulted in comparable net income of
$102,000 in the second quarter this year versus $110,000 for the second quarter
last year.

SIX MONTHS ENDED DECEMBER 31, 1996 VERSUS 1995

For the six months ended December 31, 1997, net sales increased 5% from
$4,795,000 to $5,026,000. This increase was also driven by increases in the
sales of CPE products.  Gross margin percentage was 41% for the first six months
of fiscal year 1997 as compared to 46% for the same period last year.  This
decrease was also driven primarily by the two large custom orders and normal
product mix variations as discussed above.

The reduction in gross margin percentage, netted with a 3% decrease in operating
expenses over the same period last year, reduced net income from approximately
$214,000 for the first six months last year to $143,000 this year.

The Company currently has a significant number of new products under
development.  Certain of these products require the use of outside developers
much more extensively than the Company has experienced in the recent past.
Management expects research and development expenses associated with these
development contracts to occur primarily in the third and fourth quarter of
fiscal 1997 and that these expenses will significantly reduce the Company's
reported results.

As of December 31, 1996, approximately $12,185,000 in net operating loss
carryforwards were available to offset future taxable income at varying amounts
with expiration from 2001 to 2011, as well as $290,000 and $752,000 in
investment tax and research and development tax credits, respectively.

Although the Company has adopted the Statement of Financial Accounting Standards
No. 109 Accounting for Income Taxes, there is no tax asset recognized for the
net operating loss carryforwards and tax credits due to the Company's loss
history and therefore uncertainty regarding future taxable income.  The Company
recognized no income tax expense in the first or second quarter of fiscal 1997
or 1996 due to an expected annual effective tax rate of zero.


                                                                               7

LIQUIDITY AND CAPITAL RESOURCES

The Company has two line of credit agreements with a bank renewable in September
of 1997.  The first line of credit provides for borrowings equal to the lesser
of an amount calculated based on 75% of eligible accounts receivable or $1.5
million.  This credit line is collateralized by domestic accounts receivable,
inventory and other tangible and intangible assets and contains financial
covenants including working capital and debt ratios, as well as maximum loss
provisions.  At December 31, 1996, borrowings under this line of credit totaled
$650,000.

The second line of credit is for the lesser of an amount calculated based on 90%
of eligible foreign accounts receivable and 70% of related inventory or
$500,000.  This credit line is collateralized by foreign accounts receivable and
inventory and contains financial covenants including working capital and debt
ratios, as well as maximum loss provisions.  At December 31, 1996, there were no
borrowings under this line of credit.

The Company anticipates increased spending on the development of several new
products and thus expects to continue to utilize its lines of credit.  Cash on
hand, as well as the lines of credit, should enable the Company to meet its
operating and working capital needs during the next twelve months.
