And one more item:
An MPU-IPC/IMC does not produce music. It's an MPU-401 compatible MIDI
interface. A Roland MT-32 (or similar device) was typically connected
to this interface (ie. a seperate piece of eqipment) to produce music in
DOS games.
The LAPC-1 is a complete MIDI sound card. No other equipment (besides
amplified speakers) are required.

Just to clarify some items (ie. MT-32):
The three original PC interfaces from Roland are as follows:
MPU-IPC: 8-bit ISA card that connects to a beige, external breakout box
via. 25-pin D-sub connector. Has MIDI IN, OUT, and through as well as a
metronome conenctor.
MPU-IMC: Microchannel version of the above card.
LAPC-1: Full-length 8-bit ISA card containing both the MPU-IPC and
Roland MT-32. Has 15-pin D-sub connector for attachment of a similar
MIDI breakout box to those found on the MPU-IPC/IMC.
What can become confusing when trying to identify the breakout boxes is
that the LAPC-1 also offered a breakout box which looks similar to those
found on the first two interface cards. It connects using a DB-15
connector instead of the DB-25 connector of the MPU-IPC/IMC. They
breakout boxes on the LAPC-1 and MPU-IPC/IMC are *not* interchangeable.
An MPU-IPC/IMC and MT-32 setup is functionally equivilent to the LAPC-1
with a breakout box, although the breakout box is optional on the LAPC-1
(it is not needed to produce music since the MT-32 is integrated into
the card itself).

My mistake. A quick Google shows that I had a LAPC-1 -- an MT32 on a card.
IIRC the MT-32 is a full length card. I'm fairly
sure that back in
the
day I picked one up. Can't remember how. The
music from it was
superb,
at least for the time -- probably still. I
The MT-32 is a external box by Roland, really a fancy drum syth.
Since the
smarts were basically a chip, that chip found its way to sound cards.
Most
modern motherboards and sound cards still offer MPU-401 and MT-32
emulation, even oddly enough if midi itself isn't supported.
