I have two G200 PCI cards that I know both worked. Well trying both out a few weeks ago after sitting a few years in storage, one works and the other doesn't, in the machines they came in 23 years ago. Please share the steps for BIOS recovery and I will try it.

Hi, like I said there is information on R407e already on the net, and mtech only posted partial information. Some of the …

My treshold for "smooth" must be really low - in simulated LAN game (4 computers, me as observer, medium map) it still looks OK, even with some bigger fights taking place over the map :) Version is 1.00 - I guess in its current state, after many patches, the game is way more taxing then it once was …

Aren't all PCs essentially based on 'accelerator things with faster CPUs'? I mean, a real PC is the IBM PC 5150, which runs on an 8088 at 4.77 MHz. Why does nobody use those for business applications? Actually, the 5150 was hugely popular for business. At least until the souped version of the PC …

What would those chips be good for? I mean you would be able to benchmark a very fast 486 but then what? Games that need faster CPUs can be run on a Pentium or better. Even later games will require additional instructions and at some point the CPU is so restricted by bus bandwidths that increasing …

I have a pile of 5x86s and none of them are stable 180MHz. 180 with working cache is rare enough. 200MHz with the cache on is a pipe dream. Too bad nobody can reverse engineer a 486 on a smaller process and stick it on a PGA adapter to make a super upgrade CPU. How about tracking down someone from …

Whether you buy new/old/period correct, and it doesn't matter whether it was today or buying new 20 years ago; the choice of a power supply is pretty much important as the motherboard itself. In fact, when you are building systems, you should learn how to read the specs of the power supply unit. But …

I'm sure retail store, mail-order, existed through-out the 90s. 2) I don't understand why you want to differentiate OEM-vs-retail since I pretty …

A 386 is really for someone who owned one at some point and has a sentimental value attached to it. For example I never owned a 286, and I have never felt the desire for building one... The 486 is different in this sense though, as it runs lots of games and has huge variety of upgrade possibilities …
