A genuine Roland ISA midi inferface card, such as the MPU-IPC-T, seems to cost quite a lot these days. I have one such card at the moment, it's working in my 386-40SX retro computer.

I think there were some ISA clone cards that did support intelligent mode. Those might be cheaper to obtain. Could I have a list of those cards?

The following either directly contain, or are 100% compatible with, Roland's MPU-401 chipset:

CMS CMS-401
CMS CMS-444

Midiman MM-401

Music Quest MQX-16(s)
Music Quest MQX-32(m)

Voyetra V-4000
Voyetra V-4001
Voyetra OP-4001
Voyetra V-22/24


You can also try the soundcard route. The only cards I'm aware of that "fake" intelligent mode to a usable degree are Ensoniq's ISA-based offerings, such as the Soundscape or Soundscape Elite.

The Soundscape VIVO cards are also worth mentioning. While the VIVO is cost-reduced in a number of ways - featuring software, rather than hardware, MPU emulation (requiring EMM386.exe) - this solution manages to prevent the buffer overflows common with first-gen MT-32 units (that would otherwise occur with the earlier Soundscape cards, or even an authentic MPU-401).
 
Furthermore, the Ensoniq cards can happily co-exist alongside just about anything, making them ideal as "MIDI only" cards.

I bought two of those some weeks ago, each for less than 20 and in best working condition

Music Quest MQX-32(m)

actually I bought this card a few weeks ago, but my MIDI programs did not detect the card. do I need a driver for DOS for this card?

Lucky for you! I once saw a good deal for one in Hungary but passed on it...I did get both a CM-500 and a CM-32L together for 1000 YEN (+ surface shipping).

You might see if the MQDIAG program will detect the card, found in the DOS/Windows package:

You have the card at A330, IRQ 2/9, I imagine?

thanks to the diagnostic programs I found out that there was one DIP switch in the wrong position, now it works like a charm Smiley

Finally, I got an ISA Super MPU II for a cheap price, together with a PC-98 midi interface I have no use for. Does anyone have the driver disk for it? I don't think mine comes with one.

If someone wants the PC-98 S-MPU-IIN, I'm willing to part with that one.

Hi,

I just picked up a Music Quest PC Midi Card II -- does anyone know if this happens to also be fully DOS compatible with the MPU-401 standard (i.e. intelligent mode etc. for the first gen MT-32's)?

Thanks.

Okay, I can confirm that the PC Midi Card II is NOT Intelligent mode compatible.  It says so clearly in the manual.  d'oh.

Next question, of the Ensoniq cards, is the Soundscape Opus Intelligent mode compatible?  This is the Ensoniq card that was made for Gateway computers...

I am not an expert but I do have an Ensoniq. Here is a picture from the Soundscape Elite's manual. It's the same documentation for the non-elite version (which is the one Gateway used).



"Configuration 68B50 Communications Interface, MPU-401 MIDI Interface. Emulation of MPU-401 or 68B50 UART-based MIDI Interface."

Hope that helps.
