Wow, all 74 series logic on that SCSI card, driver/host CPU must have to work it's ass off.

Is that uncommon for cards from 1993 or so?

Yes.
Even earlier controllers were more integrated and usually had custom chip able to do DMA transfers.

Interesting find I wonder how horribly slow it is 😀

I believe that is a rebranded CMI8830/A chipset.

That's right, you can see the chip on the photo. I read some good (and some not so good) things about those cards here on vogons. I will soon try myself in a 486-build.

I don't believe it is a full-blown SCSI implementation. It is more a proprietary interface to be used with Chinon CD-ROM drive. I do have a similar card, although mine is 8bit.

At that time those drives were capable of 150kB/s and multitasking wasn't a thing so speed or DMA didn't matter that much.

100% 74 series logic is more 1970s than 1990s, you could crop off the ISA connector from a pic and ppl might guess it belonged in an Altair. Even 1980s stuff was using PALs, standard and custom ASICs, microcontrollers. There's a lot of PC/XT boards that heavily relied on 74 series parts, but a full 100% is very unusual.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

It is an excellent chipset.

Got some case badges on ebay to add that extra little something to a few of my retro machines.

Then I guess I will be putting this in a "this is really neat" box

Went back to RE PC one last time to pickup a few more goodies. Matrox VLB, generic ISA controller card, Diamond Monster Fusion and a special RE PC mousepad for my wall (not pictured)

Ended up paying $100 USD for the Monster Fusion. Not a amazing deal, but people on ebay Canada are asking $170 without shipping for one. Insane.

Been a fun trip to Seattle. I head back home on thursday, gonna really miss getting to hang with the BF irl 🙁

Not bought today, but acquired quite recently, a Sound Blaster AWE64 Value CT4520. Open box. Looks new. By the teeth on the card it doesn't seem to have any signs of being inserted and/or removed from an ISA slot.

Haven't tried it out yet, not sure when I have time for that. Maybe I give it a test-drive in my 486 over the xmas break.

Oooo! Thanks! I'm testing it today, just as soon as I can replace my AT PSU that conked.

Gentlemen, maybe it is possible to take a bios dump?

It was listed as "untested, condition unknown" but it looked fine visually, apart from some rust specks on the bracket. I removed the bracket and then used sandpaper to get rid of the rusty spots. I then tried the card on my Abit KT7A motherboard (VIA KT133A chipset) but it would not post. I suspected that it didn't like the universal AGP slot, so I tried it on an Abit ZM6 (Intel 440ZX chipset) and it worked fine there. Just in case, I gave the connectors on the card a thorough cleaning using an eraser and isopropyl alcohol. After that, it magically started working fine on both systems. Weird.

Some new purchases and donates. I'm very excited about the two minitowers, cases look bad because they have been obtained from a e-waste 'dealer' but the internals... oh... the internals 😁

Soon to be featured on Rusty Bits!

Won an ebay auction last night for a Japanese Sega Saturn console. A little pricey, but it looks to be very clean. I've got an affinity for the Japanese consoles. It will be outfitted with a MODE.

I still have that board, but I don't believe I've been able to get it to POST.

I flermmed the plootash just like you asked.

And here are some of the parts found in those 2 minitower rigs I mentioned before (all works OK as far as I can tell) and in the A2000...

The triangular card in the second pic looks just like my ESS 1868F.

If so, that's a great, noise-free model. Be sure to set the jumpers to the "Line Out" position.
