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.

I never thought of that.  Very cool alternative to a bridgeboard.

Congrats!

Pretty nifty.  In my experience, a 486DX2-50 will also run Windows 98 (provided the drivers for the hardware are available.)  It's a shame this can't share resources with the Amiga side, otherwise it would have a bit more value to me, personally.

You say you found a manual; I assume the ISA bus is active and it would make use of other ISA peripherals in the Amiga?  And is that on-board networking?

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.

I'd like to run OS/2 Warp on one of these things.

The 486 CPU is surface mount, so no upgrades.

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!

You can also get Pentium boards in that form factor, some of them with Ethernet NIC...

Now that would be cool.

Those are industriual-PC-boards which work in many environments. They are available with nearly all CPU-variants (yes, even Core-CPUs like i7 QuadCore etc.) and should work in all Amigas with ISA-slots (provided the PSU is fit enough). Sometimes it needs a small modification to the ISA-slot (there is  thread on http://www.a1k.org according this topic).

I had some of those cards and it was very funny to operate a 2 GHz-system in a 8/50 MHz A2000

Unfortunately they are not very cheap.

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...

You could probably make a bridgeboard that worked alongside one of these cards. But finding someone that can do it and will put the effort in is the problem. There is software for linking PC's and Amiga's though, which should work.

Most probably it's so much easier to link them via Ethernet without any special hardware (and probably not much slower either). A bridgeboard requires dual-ported RAM and lots of protocols and system software on both sides.

Yes that was what I was referring to as "There is software for linking PC's and Amiga's though, which should work.".
 
Siamese v2.5 pro allowed you to retarget amiga graphics over Ethernet.
