Hi,

why is ibm MWave chip ignored by vintage computing community?
i know many people hated mWave but now it can be "NV1 of the sound cards"
I read about many interesting features
- fully programable DSP processor
- ISA, MCA, PCMCIA (and PCI?) busses. Later cards with PnP.
- software upgradeable by program for DSP
- small but fast SRAM memory instead of DRAM
- scalable power between sound and modem features
- relative good wavetable (with small onboard memory)
- OVERCLOCKING (interesting feature for sound card')
- 16bit audio, wavetable, modem. All inside one chip from end of the 1992 year.

- bad drivers
- DOS problem, Windows 95/98 problems.
- good working only under under Win 3.1 and OS/2?
- bad Sound Blaster emulation
- no FM chip (true Adlib compatibility)
- modem problems. slow and unstable
- class action lawsuit
- Texas Instruments drop
- piece of crap

- and more..

Now i reading articles about mWave cards. Must have hardware.

I'll have a lot of questions 😀 .

MWave is only subversion of famous TI TMS320 DSP chip? That means mWave is direct successor of the IBM M-ACPA card.

Most used "Classic" 2780 is second generation MWave chip? Or only relabelled? I found some older chip existing.
https://books.google.cz/books?id=41XoBQAAQBAJ … 320M500&f=false
TMS320M500 from was first MWave. 17 MIPS

I found only one card with M500 / TMS320M500PQL chip:
IBM WaveRunner ISDN Digital Modem (no sound card) http://ohlandl.ipv7.net/communications/waverunner.html

and (stronger) M520
TMS320M520 was used at some sound cards. Some IBM.

MDSP2780 is relabelled TMS320M520 or updated and more powerful chip?

mWave... look for mid 1990s IBM or Packard Bell systems. Most early Aptivas had the (non-PnP) IBM Dolphin mWave card, a lot of early Win95 Packard Bells had Miro Connect 34V 'Cassius' PnP cards.

I recently sold an IBM PC330 I added a Dolphin to. I was simply not able to get it running under Windows 95 with any driver combo (eventually drivers were error-free, but the mixer didn't work so no sound...), but in Windows 98SE it installed flawlessly with built-in drivers, at least once I set the base address jumper correctly.

IMHO they were interesting technology undermined by the typical IBM problem of lack of software support truly using their power. In practice you had a good Windows Sound System and 34kbps modem device with decent MIDI and dodgy SB/Adlib compatibilty - and nothing more than that. A curiosity that could be useful if not outstanding if you could get it running.

Thanks for info.
What MIDI synth is used by 98SE built-in drivers? Internal Windows softsynth same as for all other cheap FM cards? Or mWave wabetable?

You load seperate MIDI patches for mWave so I'm assuming mWave's own wavetable. Didn't actually try to use it beyond confirming it worked, so can't comment on quality. In any event the card doesn't do native FM, so anything leveraging that would be an odd choice.

I used the mirobconnect 34 back in the day and using microsoft phone with the dsp was huge fun. I had to downgrade to a sb vibra16 when i upgradee to win98. I still have my card and the driver cds

Thanks. i must learn differences between miro cards.

Her i found next mWave feature:

Mwave in 1995 IBM Aptiva Pentium I desktops was announced as MPEG Audio accelerator.
(TMS320 DSP in Antex cards was MPEG Audio accelerator too)

One point where the mWave did live up to its promise - and that might be confusing here: modem speeds were upgraded in software. So the same card that was released with 14k4 support in 1992 could (with new drivers, if you could ever get them installed) do 33k6 in 1995. So don't try to distinguish based on modem speed.

Strange issue:
Quake II v3.13 Patch https://archive.org/details/q2_313
Sound Issues:
- MWave: We have found that if you are using an MWave sound card, and are using the low quality game sounds in deathmatch, the right and left audio channels are reversed. This problem is solved by using the high quality game sounds.

I had an IBM EDUQUEST all in all one SLC 25mhz system and was mostly able to play Duke 3d with sound at a fairly good clip but I had trouble where there were too many enemies and sounds playing it would just crash, never could figure out why

Duke Nukem 3D with SLC 25MHz? Very slow CPU for Duke. I read minimum CPU is DX2/66
Eduquest cars is strange with mirrored non-ISA connector?
Is it card with original first mWave TMS320M5200?
I don't know kow this card can play wavetable sound because missing five SRAM memory chips from late MDSP2780 cards.

btw:

Have had several Aptivas and ThinkPads with MWaves in them. Their MIDI sounds quite bad and driver installation in DOS, Windows 3.x, and 9x is a royal PITA.

Where did you guys find Mwave drivers? I'm currently restoring an Aptiva model 2176 and I can't find Mwave drivers anywhere, just broken links. I currently have Win98 installed and the Mwave card isn't even detected as a ! in device manager.
