It would be interesting pulling the BIOS to see what happens. I'm not optimistic though. Wouldn't you also have to find a way to disable the VGA core?

Great. If it weren't for free trade we could have stopped the clones, and maybe the other platforms could have survived.

I think just about every manufacturer under the sun may have had their own proprietary local bus at one time or another.

Yeah. 1.44mb drives are terribly unreliable. What I never understood why the 720k drive in my Amiga (without a dust cover) never failed me once in the 20 years I owned it.

I agree. Acer made really nice cases. Actually, considering the time period the black colour was quite rare.

I got a Dual P60 EISA/VLB board recently that I'm dying to test out. There were very few Pentiums made with this combination of busses (I only know of 3 boards). Actually, in 1993 it would have been a very good (but expensive) setup.

The P75s weren't oddballs. Those were standard P54s. The P60 and P66 systems were based on the old 5V design with the non-staggered socket4 pin arrangement. Actually, I kind of have a thing for oddball systems. Though, I will usually only jump at them if I get them cheaply and find some upgrades to …

It really depends on how you look at it. At the time of release it was an absolute dog, but it still had value as an upgrade chip in older systems (if your bios could be updated to support it). It also performs quite well considering it only runs at 250MHz. Of course, I still prefer the K6+ chips.

I still like Cisco/Linksys WRT54G series. It's old, but it's solid.

I don't think there are any adapters that give the 3.6V needed for the 120. Hell, 3.6V isn't even all that common on 486 motherboards that supposedly support the 5x86. Perhaps there was a reason why the Cyrix officially supported motherboards list was so short.

Even the gainberry adapters with the Cyrix chips don't do 3.6V (from what I've seen)

Actually 80287XL, Fasmath and the IITs are already "adapted". Their cores are pretty much the same as those found in the i387SX.

Interesting. I thought AIR died during the P5 era. I didn't know they made a P6 board.

Re: Video Cards? Headland or ATI?

The Graphics Ultra isn't a bad ISA card, but it does have one major flaw...now high or true colour modes. For ISA it's reasonably fast in 256 colour windows graphics though. I'd probably stick with the Headland. Just being VLB is going to give it a huge advantage over the ATi. I believe that one …
Re: Another 486 build.... with EISA!

Something on the Nice is not right. Either you have a bad SRAM (or DRAM) or the timings are cranked up too high. Maybe the 20ns tag RAM has something to do with it. A way you can test for DRAM interleave is to remove all SIMMs from bank 1 and just run 4MB. Performance of DRAM should drop in half.

What happened to the graph in the test of the Nice board? Did you notice that the main memory read speed on the Nice is much higher than the Tyan? It is listed as 31.46MB/sec, vs about 15MB/sec on the graph for the Tyan. Looks to me as if memory interleave is not working on the Tyan. Also, you …

Maybe. But Amiga 500s were cheap too. In my opinion a typical PSX game wasn't much better than this: http://www.youtube.com/watch?v=QA3pTA2DNhc Hey PSX! 1987 is calling. They want their graphics back.
