beauty indeed!
I've got one of these too, alphatronic P50-1 with the same monitor and keyboard, I don't think I ever posted it actually, it is soooo heavy.
I even got the matching wheel printer but that unfortunately broke during shipping because it was horribly packed together with the PC itself 🙁 it's a miracle the monitor and other stuff survived.

The AudioVision Thunderboard never had any Midi support. It was my first ever x86 sound card.

The Thunderboard has jumpers to enable MIDI over the gameport, but I have no idea what kind of support it has. I doubt it is MPU401 compatible... and I doubt it'd be too useful anyway, since even MediaVision's later cards had glitchy MIDI output.

Anyway, the card in the picture is definitely a Thunderboard. They list GAME\MIDI on the box because the card claims to have some kind of MIDI support. IBM was apparently under no obligation to test that functionality before designing the box. 😁

No it didn't. I sugest you readthis thread Topic 6452

Your link doesn't work for some reason.

I'm just going by the pictures of the variant with the horizontal dip switches. It uses all of the thunderboard components, but isn't manufactured directly by Mediavision.

The card pictured on the box matches this one which is made in Taiwan...

https://en.m.wikipedia.org/wiki/Thunder_Board

The first switch on the right dip says "ENMPU".

Th99 points out that this has midi jumpers.

https://arvutimuuseum.ee/th99/i/I-L/51749.htm

Like I said, I have no idea what kind of functionality it really has... Likely none that was ever implemented by any games. IBM just put it on the box because it was on the card.

Unfortunately it’s going to need quite some effort to bring it back to it’s original glory.

That's a real beauty. I personally just tear down systems like that and clean every last corner, get everything working, put it all back together and leave it be. I like that aged (yellowing/discolored) look myself. All part of its history. Either way, please post when you have it the way you like it.

Will do (post, when done). I won’t change much, it’s more about repairing what’s broken... quite a long list.

PS: imi is right that thing is build like a tank...

Found this pretty thing.
Brand new, not a scratch on the pads under it =)

Will fit my Optiplex 560/L quite well I think!

Cool a 186, those are pretty rare, aren't they? It seems like that generation was sort of "skipped", maybe because it didn't give much over an 8086/8088?

80186 CPUs are far more common than systems that use them. They were introduced at the same time as the 286, presumable as a low end solution or for a specific market sector.

Not really, the iAPX 186 had a different operation area as it’s a microprocessor and microcontroller concurrently. Intel built an embedded version up to 2007... 3rd parties build it even today in FPGA versions with extremely low power envelopes.

Got hold of a card near the top of my 'must find'-list:

Terratec EWS64XL - with a 16MB SIMM

Friend of mine bought one in ~2000. He was intending to use it under Win2k for music production for his black metal group (er, except you weren't allowed to call it black metal despite sounding just like...), but due to driver hell it never delivered on the promise. I now bought this from someone who had gotten it to work for him, he recorded a lot of dark mediaeval-sounding folk stuff with it and used the MIDI synth for backing.

Due to absolutely no musical talent my ambitions are more limited: load that 8MB Hoontech sound bank and enjoy some DOS games 😀

Oh, and the little chips are 512kb SRAM chips to upgrade some boards to 1MB L2

Was the 186 not used in printers a lot?

That is a fantastic find and there's nothing wrong with playing your favorite dos games with an overkill sound card.

Well, I got the second to last of the Versa for the Video + a little more restoration work to video for my Youtube Channel...

I now own a Versa V/50 - the version with the non-removable screen. Same problem as my 40-EC had, cracked plastic where the hinge is, should be a piece of cake to fix on a weekend night. I'm pretty sure it works, you have to do some stupid stuff to kill one - I've only seen liquid damage or hot-swapping non-hot-swappable parts kill them - and I'm being a little overkill with the word "kill" - by Kill I mean "make the internal screen not come up", 🤣.

The goal of my video is to take one of each line.....

Ultralite Versa (PC-410 or 400 most likely)
Versa E (my 40EC I've had for 2 years already)
Versa V (this one, V/50)
Versa M (my M/75)
Versa P (my 800x600 P/75)

And show the production differences between the models, how to identify things, and of course, benchmarks. See how they really stack up against their original PC Mag benchmarks from the early 1990's. Will I keep this collection? Who knows. I know I'll be keeping at least 2-3 of them. But I know I'll be having a lot of fun finally putting my knowledge out there in something that is not just thrown together. The goals after this is get the Ultralite working (or piece one together out of broken units and reinforce it), get the touch screen fixed up - maybe even put the Ultralite Badges on it - fix one of the LCD panels I have, and then were good for the video shooting.

I have a Yamaha AW4416 24-bit multi-track recorder (I seem to be addicted to those, 🤣) on the way, which would be a great thing except... http://www.home-machine-shop.com/AW4416_RTC_R … tc_ds12887.html

Yes, I have managed to find and order something other than a PC motherboard that uses a Dallas DS12887 RTC/battery combo and, as a bonus, it is often soldered rather than socketed, or so I hear .

We'll see if I get lucky (socketed) or if I will need to have a socket soldered in (I am just not confident enough yet to try my hand at soldering on something so expensive, but I have a great place a 20 minute walk from where I live that would probably make short work of it ). Alternatively, I could try to mod the DS12887, but even that seems a bit risky to do without desoldering it first .

Oh well, live (spend) and learn .

EDIT : Why ? because I feel too lazy to do precise level matching that my current 16-bit VS-880EX requires, so a 24-bit unit seemed like a good idea (note to self : never go Ebay shopping while drunk)

EDIT2: I wonder if adding an 8 channel MY8-AE AES EBU I/O board and some S/PDIF to AES EBU converter would allow multiple S/PDIF inputs easily, or whether I would still need to find a way sync the clocks of the S/PDIF sources to the AW4416's internal clock . Even if it worked, it would not be an inexpensive solution .

I gave up trying to find an original IBM screen of the type I had with my PS/1 and went with a slightly newer model which is the same style but has far more controls and better picture quality.

It will go great with my IBM Aptiva and IBM PC 330.

I love/hate seeing things like that screen that I clearly remember throwing out at work as we upgraded!

I friend of mine used one of these to build on those https://hackaday.com/2016/07/13/expanding-hor … opelled-lifter/

so, while browsing my usual searches a few days ago this thing popped up and I was like... "sure" even though I have no idea what it is x3

at first glance it looks like a SB 1.0 clone to me with a bunch of GALs to substitute logic chips?
could not find anything about this card, there is unfortunately no FCC ID or anything on it, only a generic serial number sticker on the back.
the supposed "OPL2" does not look like a genuine yamaha chip to me so idk what's under this sticker.
edit: on second glance the chip looks the same as the "5A12" OPL2 clone chip on another card I have.

looking at the date codes it seems to be a card from 1991?

will take a more detailed picture when it arrives but I thought I'd ask if anyone knows what this is ^^

There is something vaguely familiar about that card and that "FM 12" moniker .

Try this then MediaVision Thunderboard

I repeat the original Activision Thunderboard does not have MIDI functionality. I still have the one I bought for my 286 in the early 1990.

The angled picture on the wikipedia page is not the original ActiVision Thunderboard. It's most likely an Audio Blaster Rev 1.0

Here is a picture of it so compare it to the one on that box.

Where is the mention of MIDI on pcb diagram below?

I feel like my posts aren't being read completely.

I think the confusion is coming from the fact that there are Mediavision Thunderboard variants (my exact wording in my post about this card) manufactured by other companies which have no other known name except for "Thunderboard", but are not made by MediaVision. They are 8bit cards, they have an OPL2 and they have the MediaVision MVD201 "Thunder" chip for Thunderboard compatibilty, they even have the big volume dial like a Thunderboard (though not usually white). After looking at the card more closely, I see the big difference here is that these variants also have an MVD121 chip, which is apparently a later version of the chip used on the PAS16... possibly more closely related to the Jazz16. Either way, this chip is likely the source of the MIDI functionality, and is the reason that the card has MIDI jumpers and is advertised has having MIDI support on the box. It may or may not work any better than the MVD101 based cards with bugged MIDI, but the functionality DOES exist on this card... not the original manufactured by MediaVision.

I have no doubt that you have the original Mediavision branded card and that it has no MIDI functionality. You have to acknowledge the fact that there are other variants of this device in existence. If you're arguing that they shouldn't be called Thunderboards, then maybe we can help each other figure out what they should be called and then go about correcting the many many sources online that refer to this card (with an MVD121 chip and MIDI jumpers) and call it a Thunderboard.
