Item 2.   Disposition of Assets

          On July 15, 1998, Cable TV Fund 12-A, Ltd., a Colorado limited
partnership (the "Partnership"), sold the cable television system serving areas
in and around Fort Myers, Florida (the "Fort Myers System") to an unaffiliated
cable television system operator for a sales price of $110,000,000, subject to
customary closing adjustments.

          From the proceeds of the Fort Myers System's sale, the Partnership
paid a brokerage fee to The Jones Group, Ltd., a subsidiary of Jones Intercable,
Inc., the general partner of the Partnership (the "General Partner"), of
$2,750,000, representing 2.5 percent of the sales price, for acting as a broker
in the transaction, settled working capital adjustments and will distribute in
August 1998 the remaining net sale proceeds of $106,854,400 to its partners of
record as of July 15, 1998.  Pursuant to the terms of the Partnership's limited
partnership agreement, from the net sale proceeds the Partnership first will
return to the limited partners the capital they initially contributed to the
Partnership ($52,000,000), and the remainder will be allocated 75 percent to the
limited partners ($41,140,800) and 25 percent to the General Partner
($13,713,600).  The total distribution to limited partners of $93,140,800
represents $896 for each $500 limited partnership interest, or $1,792 for each
$1,000 invested in the Partnership.

          The Partnership's remaining assets are the cable television systems
serving areas in and around Lake County, Illinois (the "Lake County System") and
Orland Park/Park Forest, Illinois (the "Orland Park System").  On July 10, 1998,
the Partnership entered into an agreement to sell its Lake County System and
Orland Park System to an unaffiliated party for a sales price of $86,000,000.
Closing of the sale of the Lake County System and the Orland Park System is
subject to several closing conditions, including the consents of franchising
authorities and the approval of the holders of a majority of the Partnership's
limited partnership interests.  Upon the sale of the Lake County System and the
Orland Park System, which is expected to occur in the fourth quarter of 1998,
and after the termination of the indemnity escrow period on November 15, 1999,
the Partnership will be liquidated and dissolved.

          Taking into account the anticipated distributions from the sales of
the Fort Myers System, the Lake County System and the Orland Park System, the
General Partner expects that the Partnership's limited partners will have
received a total return of $1,361 for each $500 limited partnership interest, or
$2,722 for each $1,000 invested in the Partnership, at the time the Partnership
is liquidated and dissolved.

     The following unaudited pro forma balance sheet assumes that as of March

distributed to the partners of the Partnership.  Pursuant to the terms of the

allocated 75 percent to the limited partners ($41,140,800) and 25 percent to the
