EBAY: SBC 486 50MHz (not mine)

[psxphill]

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.

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.

Try to get yourself an ISA Gravis Ultrasound card.

0% CPU usage.  Made my 486 sx25 fly back in the day!

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

Hey Nicholas,
Haven't seen you around lately.

Great Vonnegut quote.


I'd had that thought before in relation to a '386 or '486 bridgeboard, but Warp really requires a VGA card (at least version 3 does).
You can also run Win3.1 under later versions of Warp.

Use of an ISA VGA card is possible, but then you are dealing with two separate displays.

Has anyone tried to use a Sigma Designs ReelMagic card in an ISA slot with a bridgeboard or sbc?

Under Warp that should allow Mpeg decoding at 640x480 in 256 colors.

[Iggy]

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 used to have two of those overdrive chips.
Curious hybrid between '486 and Pentium.
Smaller then a Socket 7 processor.

Wound up throwing them away when I inadvertently bent the pins.

Hi Iggy,

Hope you are well, I was busy with real life for quite a a while but the opiate-like Amiga addiction can't be ignored!

Reelmagic cards are a blast from the past. i remember testing one under Windows "Chicago" in 94 and being blown away by the full screen MPEG playback.

I used to have one of them in my old Commodore 486 with Paradise VGA card and Gravis Ultrasound.

It ran DOS, OS/2, NT 3.51 and Yggdrasil like a dream.

I even ran a trialware copy of SCO Unix on it for a while.

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

There has to be some ISO mounting software out there that still works with Win9x.

You might want to look around here:

http://www.oldversion.com/

If not, you might be able to find a cracked executable for Descent that will allow it to be run off the hard drive. I had kept my Win9x software collection for years before I finally deleted the folder, I regret that as I had some very hard to find items in my collection, things I may never recover again which would come in handy for situations like this.

if it could recognize the PCI slots of mediator or Micronik daughterboards it would be even more cool :-P

[Iggy]

Does anyone know where I can get the connectors to convert my two 8 bit slots to 16 bit?

[Xanxi]

Plugging a SBC card into a Mediator would certainly cause major damages.
The PCI slots can't be active for the Amiga and the PC side at the same time.

I have the same problem with an AtéoBus (which is merely an ISA bus with no DMA support): i would like to put there a Pentium MMX SBC that i have but there would be big conflicts with the Amiga.

These cards can only live with the Amiga in 100% inactive slots, such as the ISA slots of the A2000/A3000/A4000.

That could be true for mediator but old micronik busboard had PCI slots not accesible for the Amiga so i assume that it is only for SBC boards

I wasn't aware of that.
Why did they bother?
If they weren't accessible the majority of users wouldn't have a use for them.

And while this whole discussion is interesting, in practice these ideas aren't too practical.
Basically what you have is two separate computers in one case.

But then face it, we don't always do things because they make good sense.
Sometime we do it just because we can (the neato factor).
