                                    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 September 30, 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
September 30, 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 $365,733 which includes
landowner royalties. Expenses for this period include $75.00 per month per
well for administrative costs and $275.00 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 drilling funds will be required.

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.  Management does not anticipate that the Partnership will
need to borrow. 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 September 30, 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.

               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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

RESULTS OF OPERATIONS

NINE MONTHS ENDED SEPTEMBER 30, 2000

Natural gas sales revenue for the nine months ended September 30, 2000 was
down $87,754 (8%) due to declines in natural gas production. Gas production
for the nine months ended September 30, 2000 was 399,429 Mcf, down from
586,848 Mcf in the prior year. The decrease in gas production results
primarily from normal declines.  Natural gas prices for the nine months ended
September 30, 2000 increased by $.78/Mcf to $2.96/Mcf.

QUARTER ENDED SEPTEMBER 30, 2000

Natural gas sales revenue for the quarter ended September 30, 2000 was down
$1,651 from the prior year's third quarter due to lower gas production.  Gas
production for the quarter ended September 30, 2000 was 123,450 Mcf, down
from 171,701 Mcf in the prior year's third quarter.  The decrease in gas
production results primarily from normal well declines.   Natural gas prices
for the quarter ended September 30, 2000 increased by $.95/Mcf to $3.39/Mcf.

FINANCIAL CONDITION

LIQUIDITY

The decrease in cash provided by operating activities and distributions to
partners during the nine months ended September 30, 2000 results primarily
from lower cash received from sales of natural gas. The Partnership's working
capital increased from $297,913 at December 31, 1999 to $326,558 at September
30, 2000. The increase is attributable to higher accounts receivable compared
with December 31, 1999 due to higher prices for natural gas production.

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.
