I've used the second link (http://john.ccac.rwth-aachen.de:8000/misc/ps2cache/) and it was rather painless, it took me just a few hours to mod four SIMMs. If you're nearby (Germany/Europe), I can send you some modified 1MB ones. I'll send you a tool to dump BIOS later, I don't have it at hand. The …

im not sure if full recap can fix these issues. I also have them from time to time older boards are full of 22uf 25v caps everywhere. You can get a 486 board with more than 20 of those 22uf caps. do those make any difference at all? or the bigger caps are the issue?

While waiting for the XT-IDE, you should also purchase the IDE-CF adapter from your favourite Chinese seller. It's easier to pull the CF card and shove it into a USB reader than messing with HDD. This one should plug directly into the XT-IDE. I hope you've ordered the XT-IDE with power connector, …

As for the "special" SIMMs needed for Model 30/286, it's relatively simple to mod regular SIMMs to work in PS/2 machine. Trident ISA cards usually work in 8bit machines (I use one of them in Commodore XT) - there are usually jumpers that can configure the card for 8bit support: http://www.vcfed.org …

I have a model 30 too. The greatest advantage for me is that it is one of the few XT class computers that use ‘modern’ connectors for keyboard, mouse and display. I use a KVM switch to share PS/2 keyboard and mouse and LCD display with my 486 and Pentium III machines. I use an XT-IDE Compact Flash …

As someone who enjoys the IBM ps/2 models. I have to say, a 25 or a 30 is just fine, but are DEFINITELY not for beginners. If you are already familiar with the major quirks of 808x and 286 era systems, then getting a 25 or 30 is just adding a few more quirks to the pile. However they are usually …

$50 is a decent price for a working machine. The cpu is RATED for 8mz. The value of Y1 right next to it will tell you how fast it REALLY is running. New player trap; the crystals often run at 2x the cpu speed. IBM was always conservative on cpu speeds. that card in the top slot is to add an …

Sweet machine. These days you have to be grateful to even find decent OEM units for fair prices. I pad 50 dollars for it, and im happy. Its not like im going to use it often, i used a 8086 when i was a kid and i don´t miss it. But i had the opportunity to get this IBM and i did not doubt to buy it. …
