                      IDS/JONES GROWTH PARTNERS II, L.P.
                      ----------------------------------
                            (A Limited Partnership)

             NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
             ----------------------------------------------------

(1)     This Form 10-Q is being filed in conformity with the SEC requirements
for unaudited financial statements and does not contain all of the necessary
footnote disclosures required for a complete presentation of the Balance Sheets
and Statements of Operations and Cash Flows in conformity with generally
accepted accounting principles. However, in the opinion of management, this data
includes all adjustments, consisting only of normal recurring accruals,
necessary to present fairly the financial position of IDS/Jones Growth Partners
II, L.P. (the "Partnership") at September 30, 2000 and December 31, 1999, its
Statements of Operations for the three and nine month periods ended September
30, 2000 and 1999 and its Statements of Cash Flows for the nine month periods
ended September 30, 2000 and 1999. Certain prior period amounts have been
reclassified to conform to the 2000 presentation.

        The accompanying consolidated financial statements historically include
100 percent of the accounts of the Partnership and those of IDS/Jones Joint
Venture Partners (the "Venture"), reduced by the 34.4 percent minority interests
in the Venture. All interpartnership accounts and transactions have been
eliminated. Jones Cable Corporation, a Colorado corporation, is the "Managing
General Partner." Neither the Partnership nor the Venture currently own any
cable television systems. The Venture has distributed or will distribute its
remaining cash to its constituent partners in the third and fourth quarters of
2000. The Partnership's only current asset is cash on hand. It is anticipated
that the Partnership and the Venture will be fully liquidated and dissolved by
December 31, 2000.

        Prior to its dissolution, the Partnership will accrue funds to cover its
remaining administrative costs. All cash remaining after such accrual is made
will be distributed to the Partnership's partners pursuant to the distribution
procedures established by the Partnership's limited partnership agreement. It is
expected that all limited partners will receive final distribution checks from
the Partnership before the end of December 2000.

        On April 7, 1999, Comcast Corporation ("Comcast") completed the
acquisition of a controlling interest in Jones Intercable, Inc. ("Jones
Intercable"), the parent of the Managing General Partner until March 2, 2000. In
December 1999, Comcast and Jones Intercable entered into a definitive merger
agreement pursuant to which Comcast agreed to acquire all of the outstanding
shares of Jones Intercable not yet owned by Comcast. On March 2, 2000, Jones
Intercable was merged with and into Comcast JOIN Holdings, Inc., a wholly owned
subsidiary of Comcast. As a result of this transaction, Jones Intercable no
longer exists and Comcast JOIN Holdings, Inc. continued as the surviving
corporation of the merger. On August 1, 2000, Comcast JOIN Holdings, Inc. was
merged with and into Comcast Cable Communications, Inc., ("Comcast Cable"),
another wholly owned subsidiary of Comcast. The Managing General Partner is now
a wholly owned subsidiary of Comcast Cable and, as such, is an indirect wholly
owned subsidiary of Comcast. The Managing General Partner and Comcast Cable
share corporate offices with Comcast at 1500 Market Street, Philadelphia,
Pennsylvania 19102-2148.

(2)     The Partnership reimburses its Managing General Partner for certain
administrative expenses. These expenses represent the salaries and related
benefits paid for corporate personnel. Such personnel provide administrative,
accounting, tax, legal and investor relations services to the Partnership. Such
services, and their related costs, are necessary to the administration of the
Partnership until it is dissolved. Such costs were charged to other expense on
the Statements of Operations. Reimbursements by the Partnership to its Managing
General Partner for administrative expenses during the three and nine month
periods ended September 30, 2000 were $10,770 and $41,054, respectively.
Reimbursements by the Venture to its Managing General Partner for administrative
expenses during the three and nine month periods ended September 30, 1999 were
$10,953 and $26,761, respectively, of which $7,185 and $17,555, respectively,
were attributed to the Partnership's 65.6 percent interest in the Venture.

        IDS Cable II Corporation (the supervising general partner of the
Partnership) and IDS Cable Corporation (the supervising general partner of
IDS/Jones Growth Partners 89-B, Ltd.) may also be reimbursed for certain
expenses incurred on behalf of the Partnership and the Venture. There were no
reimbursements made to IDS Cable II Corporation or IDS Cable Corporation during
the three and nine month periods ended September 30, 2000 and 1999.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        ---------------------------------------------------------------
                             RESULTS OF OPERATIONS
                             ---------------------

FINANCIAL CONDITION
-------------------

        The Partnership owns a 65.6 percent interest in the Venture. The
accompanying consolidated financial statements historically include the accounts
of the Partnership and the Venture, reduced by the 34.4 percent minority
interests in the Venture. Neither the Partnership nor the Venture currently own
any cable television systems. The Venture has distributed or will distribute its
remaining cash to its constituent partners in the third and fourth quarters of
2000. The Partnership's only current asset is cash on hand. It is anticipated
that the Partnership and the Venture will be fully liquidated and dissolved by
December 31, 2000.

        Prior to its dissolution, the Partnership will accrue funds to cover its
remaining administrative costs. All cash remaining after such accrual is made
will be distributed to the Partnership's partners pursuant to the distribution
procedures established by the Partnership's limited partnership agreement. It is
expected that all limited partners will receive final distribution checks from
the Partnership before the end of December 2000.

        The Partnership's current and periodic reporting obligations under the
Securities Exchange Act of 1934, as amended, and the Partnership's quarterly and
annual reporting obligations under Section 3.7 of the Partnership's limited
partnership agreement will cease upon the Partnership's termination. As a
result, it is expected that this quarterly report on SEC Form 10-Q for the
quarter ended September 30, 2000 will be the Partnership's final detailed
financial report to limited partners.

        During the first quarter of 2001, the Managing General Partner will
deliver final tax reports on Form 1065, Schedule K-1 to all limited partners of
record as of the date of the Partnership's dissolution. If, as expected, the
Partnership is dissolved before the end of 2000, the Partnership and its
partners will have no tax reporting obligations beyond the taxable year 2000.

RESULTS OF OPERATIONS
---------------------

        Neither the Partnership nor the Venture currently own any cable
television systems. Other expense of $110,788 incurred in the first nine months
of 2000 related to various costs associated with the administration and
liquidation of the Partnership.

                          PART II - OTHER INFORMATION


Item 1. Legal Proceedings.

        The Partnership and the Managing General Partner are among the
defendants in a case captioned Everest Cable Investors, LLC, et al., plaintiffs
                               ------------------------------------------------
v. Jones Intercable, Inc., et al., defendants (Superior Court, Los Angeles
---------------------------------------------
County, State of California, Case No. BC 213632). The case was originally filed
in July 1999. Subsequently, demurrers were sustained as to a substantial portion
of the action, and the court did not allow the plaintiffs to seek to amend and
re-file their claims. As a result, the plaintiffs elected to appeal the ruling
of the trial court as to the validity of their claims which had been dismissed.
While the appeal is pending, the trial court agreed to the parties' joint
request to stay the portion of the action that was not dismissed by the trial
court when it sustained the demurrers.

        The Partnership has continued in existence since the sale of its cable
television system assets. The Managing General Partner has determined, however,
that it is in the best interests of the Partnership and its limited partners to
liquidate and dissolve the Partnership before the end of the year 2000.

        Although, prior to its dissolution, the Partnership will accrue funds to
pay for its remaining administrative expenses, the Partnership will not accrue
funds to cover its potential liabilities related to this litigation. Instead,
the Managing General Partner will remain liable for the Partnership's
liabilities, if any, related to this case.
