Trance88 Indeed, the M-ACPA supported 16-bit audio years before the Sound Blaster 16 and Gravis UltraSound were introduced!

The ACPA could do 88.2kHz mono sampling or 44.1kHz stereo, both 16-bit. I think it might have had other sampling options, I can't recall.

Lol, same here. I like this guy too :)

The synthesizer sounds like an FM chip, but not an OPL-3. Or it's a basic analog synthesizer chip. I'm also curious if the current "M-Audio" brand (currently part of Avid) has its origins in the manufacture of this card.

Same but 2022.

Classic SCSI-2 was so good, it was a packet-based protocol, so all hardware on the bus could be accessed in realtime without interfering with each other (I used it on the Amiga 3000 and on my first PC, which was a P-90). When the SCSI consortium decided to include burst mode in future standards (to bring transfer rates up to par with IDE), I gave up on SCSI in later PC builds. Because burst mode blocks the bus, just as in IDE.

You confuse rarity with quality.

Robert Hoellering It's not a new camera, it's just a new way of editing the video. :-) It's the same Canon FS200 that I've been using for most of my videos since late 2009.

Still looks really good

vwestlife Well, 60p is always appreciated.

even my IBM Aptiva from 1994 that is not a PS/2 or Microchannel plays CANYON.MID

I've been wondering for a while if this was possible. Now I know. Thank you.

vwestlife Synthesizery

Lachlant1984 He has a PS/2 Model 30 with an 8086 CPU, which has regular ISA slots, so a standard Sound Blaster card will work. It's his PS/2 Model 80-386 tower system that has the MCA bus and M-ACPA sound card.

vwestlife Yes, I watched that video about the PS/2 80 after posting my comment. You're right.

Way past the expiration date on this reply, but in case anyone is wondering... IBM loved to include onboard diagnostics. It’s an engineer’s dream to be able to put hardware into a self-test and report any failures. So this card has a feature that lets it test the audio in and out (DAC / ADC) by looping the audio out back into the audio in. The card can then play test samples and record it back to make sure the audio path is functional. They included special “switching” jacks that detect the presence of an inserted plug. These jacks are usually used to do things like mute integrated speakers when headphones are plugged in ... that sort of thing. In this case, when there’s nothing plugged in, they connect the out to the in in a “loop back” condition. Plugging something in to either the input or output is supposed to break this loop and allow the card to work normally - i.e., not in test mode. If the loop is not broken, then some of the output gets mixed back in from the input, but with some delay and phase changes inherent when you introduce reactive components like DC-blocking capacitors. Hence the odd sound. The sensible thing to do might have been to have the user plug in a test cable (like any ordinary 3.5mm male to male cable) rather than defaulting to looped unless a plug is inserted. Or, use a jumper or software controlled relay to switch to test mode. But IBM didn’t really see the user-experience issue with this. “The manual clearly tells you this will happen, and we included a Y-cable you can plug in to avoid it. What’s the problem? Didn’t you read the manual, cover to cover?”

I have like 4 MCA Sound cards but yea I also paid a lot to get em... I wish there was made more MCA Soundcards so more IBM PS/2's should get real sound.

@@AnagramFoilBalloonFan are you able to pop a list of the model names for the mca sound cards up? My model 95 reaaaaly needs a sound card but i dont know what to search for aside from "mca sound card"

@@Colt45hatchback SoundPiper 16, ChipChat 16, Soundblaster MCV Pro 2. but I sold mine and sold my IBM PS/2 collection.

@@AnagramFoilBalloonFanthankyou. Aww thats unfortunate. I sold most of my ps2 stuff a while ago (before it was valuable naturally) aswell and just kept my model 95... which to my stupidity, was the only one without a sound card....lol silly me. Could have easily slapped on in from the other computers.. well. Now the hunt begins. Haha

The ReSound MCA card is available new today for about $50

Well dang that was a timely reply if I ever saw one. (You interrupted me watching another one of your videos lol, the QBOS stereo system) anyway, thanks!

+vwestlife where do you find these songs? Some of them are awesome! :D

I mentioned that in the video.

Sorry, I skipped part of it when win3.11 was too much (I'm not into it) but the only DOS related thing I found was a single demo running under DOS. I tried to find more again, it's the same. And at the setup screen I can't see any legacy port (like 220, 388, 530 or similar) nor DMA channel. I was kind of curious how these PS/2 things worked because I have a MCA SBPro2 which I'll probably never see working but it's so interesting that I kept it when I bumped into it.

ThatGuyYouKnow It was shown and mentioned in the video.

James Dalpiaz In this case, it stands for Adapter Description File.

Oh, Alright, that makes sense. As soon as you said ADF my brain registered it as Amiga Disk Format. I have an old Amiga 500 that I play around with from time to time.

CLONEWARSADVENTURES0 Yup Jon from Jogwheel confirmed it

Nice job designing this, IBM...

+AIO inc. Mca also looks like a pci express you could say.

+AIO inc. also, what model ps/2 is this?

It is an IBM PS/2 Model 56 SLC.

Of course. But they did fairly well. I have a PC World from 1992 that I was thumbing through the other day. It mentions the 56 SLC as an upcoming model. It also shows the top 10 selling machines at the time. PS/2s are in the number one and two spots. Maybe #3 as well, I don’t remember for sure. So. _Somebody_ was buying them! MCA has a ton of really cool features. It also had some very IBM features, like the whole reference disk thing. Would have been much better if every MCA card had a ROM on it with the ADF and DGS files (well, the content, anyway) stored onboard.

@@nickwallette6201 As they say, "nobody ever got fired for buying IBM." I wouldn't mind getting my hands on a PS/2, but much like the IBM PC/XT/AT models, they've become semi-collectors items (though I see a couple listings that aren't a bad price right now). Best way to get them for cheap is to look for listings that say "parts/repair" and fix them yourself.

@@BlackEpyon Hah... yeah, I have a Model 30, a Model 30 286, and a Model 70 386. Not a single one of them was turn-key. These things vary from "some maintenance required" to the complete basket-case my M70 turned out to be. At the very minimum, most of the floppy drives need to be completely disassembled, cleaned, and lubed. The motor board and sometimes the controller PCB need to be recapped. The M30-286 had a Sony drive that seems to be OK, but the M30 720K Alps drive needed to be recapped to get it working right. The Mitsubishi in the M70 ruined the pads on the controller PCB and was in process of ruining the motor PCB. I'm just getting that one back together and am not optimistic that it'll work, at least off the bat. The 8-bit XT IDE hard drives seem to have capacitor issues as well, and one of mine seems to have almost completely lost head #3 somehow. The PSU in my model 70 was leaking electrolyte all over the place. That was pleasant to clean up... I replace all the tantalum caps on the motherboard too, to keep them from popping -- which I can't imagine is kind to the PCB or the PSU. This is not always easy with those three-legged caps, and sometimes the board stuffers were kind enough to bend the legs against the board on the solder side, making them impossible to pull straight out. The 70 in particular was SUCH as PITA. IBM designed that board with several of the caps tied to the inner power planes (of course), and apparently doesn't believe in annular rings around the vias, so getting enough heat into them to melt solder all the way through the board was a challenge, to say the least. The aftermath wasn't pretty, but I think I managed (somehow!) not to dislodge any vias. These things were proprietary, ill-conceived, butt-ugly, failure-prone junk. And I love them to death.

@@nickwallette6201 One of my current projects is restoring a Hyundai XT clone (Super 16TE), and yeah, similar issues. I keep hearing that tantalums are superior to electrolytics, but electrolytics usually just "fade" away, where tantalums tend to fail much more... spectacularly. But after replacing the tantalums, the dead Varta, and one of the ISA slots the Varta corroded, I've gotten it mostly working. The one remaining issue has to do with the memory banks. Banks 1 & 2 are soldered onto the board, but banks 3 & 4 are socketed. Populate bank 3, get 576K, and everything tests fine. Populate bank 4 for 640K, and bank 4 tests fine, but bank 3 stops working. Tried replacing the chips, but I suspect the issue has to do with some of the support logic. And, alas, no technical reference manual to be found. I picked up a lo-tech 1MB RAM card, because I wanted to run with some HI-RAM for loading drivers and whatnot, but it would be nice to get that last bank working. Probably just end up replacing those surrounding logic chips outright, and see if that fixes it.

Haha... yeah, I dunno about electrolytic being better or worse than tantalum. When 'lytics have a bad day, they cause a lot of collateral damage. Tantalums stress out the power delivery, and might damage a nearby component. I think I'd take neither, if I could. :-) But what're you gonna do. That problem with the RAM does sound like maybe an address decoder has a stuck bit or something. If it's Chip-Enabling something in bank 4 that drives the bus while bank 3 is trying to use it, or something like that. Hope you get it fixed. It's always rewarding to bring something back from the brink of the dead.

yea I know right? IBM PS/2's are very complicated... u need a reference disk to get rid of error codes after installing or removing a card. if the floppy drive breaks down its hard to find other floppy drive since it need to be a spiecal floppy drive

what windows menus?

They were blazing trails back then. First PC to standardize on the 3.5” before it was solidified into the form factor we know now. MFM/RLL was old tech but IDE wasn’t yet prominent. SCSI was just taking off. ESDI drives, and the 8-bit IDE used in earlier PS/2s were precursors to what everyone knows as IDE. MCA had a lot of good ideas, but IBM was very much an engineering company. Very little thought into user experience, or even whether the decisions made today will still fit in two to five years. PS/2s had their strengths, and they made the newest Intel architectures available before anyone could afford them. By the time most of us were using a 386 like this, we were using clones with a couple years of hindsight to learn from IBM’s missteps.
