Just practice mate... Never had any training or anything... Read some guides on the web and practice on some dead boards 😀

I like to know:

I saw that in the bios configuration that the option for Graphics mode is EGA..
I had played with some of mine 286 boards, that some are only possible to select till EGA mode.. Would VGA be supported by the whole system. So make it sense to use a VGA card if the bios cant support greater then EGA?

Great thread. Thanks for sharing!

I don't have this system any more, but I have successfully used a VGA card, and played VGA games on this system.

why did you sell it?

I needed to clear out some storage space and I wasn't using it.

It was fun to build and I learned a lot but ultimately, most pre-VGA games were available as a superior Amiga port, and that's the system I was playing them on.

DonutKing: Lovely machine no doubt about 😀 And thanks to your thread, an idea popped into my head. And that was the thought "286 overdrive", And bloody hell. I was astounded with what I read, there actually were 286 "overdrive" cpus. So if you ever felt like you wanted to make something fun (in the future and if the money was right). You could try to hunt down a 25 mhz 286 and try to find an overdrive for it, and then perhaps do some serious "old school" pimping for that machine too, and of course "cheating" would be accepted, like CF cards, as an HDD and what not. Even though by the "true" retro people. They would perhaps frown upon it 😀 Anyway, great thread and thumps up, from the north of Europe 😀

I have ran an "overdrive" chip in a 20MHz 286 before. It ended up becoming a clock doubled Cyrix 486SLC with 1kb cache. I later got an IBM 486SLC-66 with 16kb cache, but unfortunately that was after I sold the 20MHz 286. To be honest I didn't like the feel of the upgraded 20MHz 286, because it felt no different from a 386SX.

At the moment I have an original 8MHz IBM 5170 (model 319) with a Ti486SXL with 8kb cache running at 48MHz. Yes, that is a 6X external clock. I have tried to get the IBM 486SLC2 going in there, but I was having conflicts with the AHA 1542 SCSI controller. It might be possible to get it going though, as there are a lot of CPU registers to play with.

The 486SLC2-66 is the fastest direct upgrade for a 286 that I am aware of. There *may* be a 100MHz SLC3 upgrade out there, but I am not aware of it. It actually wouldn't improve things much since the really slow memory holds things back. It may be possible to upgrade to a full blown 486 or 5x86 if you combined the right adapters, but that might be asking for trouble.

this is real Rerto!

Fantastic read. Thanks for sharing. Great machine you have there! 😀

He HAD it, he already sold it..
