                                    PART I

Item 1.  Financial Statements

The unaudited Financial Statements of Atlas-Energy for the Nineties-Public #6
Ltd. (the "Partnership") for the period January 1, 2000 to March 31, 2000.

Item 2.  Description of Business

The Partnership has placed into production 44.45 net wells to the
Clinton/Medina formation in Mercer and Lawrence Counties, Pennsylvania. As of
March 31, 2000, all 44.45 net wells are in production. The first quarterly
distribution was on June 8, 1998 for natural gas production during
January, February and March, 1998.

Natural gas sales revenue for the three months was $331,411 which includes
landowner royalties. Expenses for this period include $75.00 per month per
well for administrative costs and $275,000 per month per well for pumpers
fees.

For the next twelve months management believes that the Partnership has
adequate capital. No other wells will be drilled and, therefore, no additional
funds will be required.

Although management does not anticipate that the Partnership will have to do
so, any additional funds which may be required will be obtained from
production revenues from Partnership wells or from borrowings by the
Partnership from Atlas or its affiliates, although Atlas is not contractually
committed to make such a loan. No borrowings will be obtained from third
parties.

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

                 ATLAS-ENERGY FOR THE NINETIES--PUBLIC #6 LTD.
                       A PENNSYLVANIA LIMITED PARTNERSHIP


1.   INTERIM FINANCIAL STATEMENTS

     The financial statements as of March 31, 2000 and for the three months then
ended have been prepared by the management of the Partnership without audit,
pursuant to the rules and regulations of the Securities and Exchange Commission.
Certain information and footnote disclosures normally included in the financial
statements prepared in accordance with generally accepted accounting principles
have been omitted pursuant to such rules and regulations, although the
partnership believes that the disclosures are adequate to make the information
presented not misleading. These financial statements should be read in
conjunction with the audited December 31, 1999 financial statements. In the
opinion of management, all adjustments (consisting of only normal recurring
accruals) considered necessary for presentation have been included.

2.   SIGNIFICANT ACCOUNTING POLICIES

     The Partnership uses the successful efforts method of accounting for oil
and gas activities. Costs to acquire mineral interests in oil and gas properties
and drill and equip wells are capitalized. Oil and gas properties are
periodically assessed and when unamortized costs exceed expected future net cash
flows, a loss is recognized by a charge to income.

     Capitalized costs of oil and gas wells and leases are depreciated, depleted
and amortized by the unit of production method.


                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                 ATLAS-ENERGY FOR THE NINETIES-PUBLIC #6 LTD.


Management's discussion and analysis should be read in conjunction with the
financial statements and notes thereto.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 2000

Natural gas sales revenue for the three months ended March 31, 2000 was down
$67,987 (17%) due to declines in natural gas production which decreased from
224,614 Mcf in the three months ended March 31, 1999 to 141,055 Mcf in the
current three months. The decrease in gas production results primarily from
normal declines in well production in the current three months. Natural gas
prices increased by $.66/Mcf to $2.68/Mcf during the current three months.


FINANCIAL CONDITION

LIQUIDITY

The decrease in cash provided by operating activities and distributions to
partners during the three months ended March 31, 2000 results primarily from
lower cash received from sales of natural gas. The Partnership's working
capital decreased 5.61% from $297,913 at December 31, 1999 to $281,186 at
March 31, 2000. The decrease is attributable to normal declines in natural
gas production from the levels at the end of 1999 which result in lower
receivables in connection with sales of gas produced.

CAPITAL RESOURCES

There were no new material commitments for capital expenditures during the
period and the Partnership does not expect any in the foreseeable future.
