EBAY: SBC 486 50MHz (not mine)

[amiman99]

I got this 486 50MHz SBC (single board computer) on Ebay few days ago, and I'm very pleased to know that it works fine in my A3000 plugged in in the ISA slot. I was surprised that Win 95 works fine with 16MB and 486 CPU.
It's not a bridgeboard, but a full fledged computer on ISA card (minus sound). So far I got Win95 and Descent installed on it and it works great.
Next is Doom, Doom 2 and will see if Quake 1 works on it.
There are 3 left at $49.95 or Best Offer, I also found PDF manual for it.

I may have to move that card to A2000, there is more space in it then in A3000.

Would be cool if one of those Pentium Overdrive chips that fit in a 486 socket would work on one of these as $50 is very cheap.

There is a similar board with a Pentium 100 and onboard SCSI for sale on eBay for £99.

The 486 CPU is surface mount, so no upgrades.

And is that on-board networking?

Yes, it's got 10baseT, NE2000+ compatible, Win95 did not find it, so you have to configure it manually, I can ping loopback, so looks like is working.

If I remember correctly, 4MB was needed to run Win95, 8MB to run is smoothly. I upgraded my 486 DX2-66 to 20MB. That was a nice system! BTW, install Dark Forces if you got the chance. Great game!

I run, back in 1996 or later, win95 with 4Mb RAM, it was a nightmare! AOL would take forever, and I mean forever to load. the virtual memory would go crazy in full overdrive!
It was faster to go online with my A1200 then with that windows box.
Memories...

OK, I got myself brand new ISA sound card today from my local PC store. Plugged in the second ISA slot, fired up the board, and Win95 recognized it, so the ISA slots are active and working, Cool!
so far, very nice, looks like I have full 486 PC inside my Amiga.
I have couple game installed on it and work great, the only thing I don't like is that WWF Wrestlemania and Descent 2 requires a CDROM to work. I was planning to install the games, remove the CD drive and play.

Curious how these work .. do you actually need a functional amiga in order for this to work?

Or could you use one that had a lot of battery damage? I guess as long as it gets all the signals it needs through the ISA slots?

Sorry, just don't know anything about these boards but it sounds pretty neat to use in a damaged 2000 that has no other uses (besides being a resource for parts).

I think it's going to work, as long as it provides power to the ISA slots.
It maybe ba good fit for broken A2000. Plug the CPU card in one of the ISA slot, and use the other ISAs for additional cards, because it provides active signals and enables the ISA. I got the sound card working like that.
You can remove the Amiga floppy drive and install a PC one, then use the 5 1/4 spot for the IDE CDROM drive.
Functions like a normal 486 PC.
That gives me idea to make another YouTube video...

I wanted to upgrade the RAM to the max and this board takes max Fast Page 32MB RAM at 3.3V, is that something unusual?
All I can find is 5V SIMMs
