Re: Best 100mhz FSB Processor? (that I currently own!)

Fascinating. Interesting that the FSB bottleneck at high mult is significant enough that the cache reduction makes that big a difference.

With Slot 1 it should be pretty easy to try both and check. That's one of a small number of reasons I do like the slotted form factor. Cooler comes away with the cpu, no need to fool around with coolers or thermal paste when you swap as long as both still have coolers.

1GHz celeron w/100MHz FSB is extremely likely to slap around a 750MHz PIII w/100MHz FSB for games. Having twice the cache will not save the PIII from the fact it's only running at 75% of the clock speed of the celeron.

Re: 386 with 4GB?

The ram size would be limited by the memory controller in the chipset, yes? So, with a 386 hooked to a compatible FPGA "chipset" hooked to a DDR3 chip... Regardless I very much doubt anyone would have hooked 4GB of RAM to a 386. Consider how long it would take a 386 just to zero 4GB of RAM, much …

The "ANSI-from-Hell" graphics rely on the contents of IBM's character ROM - many non-IBM CGA boards have the exact same 8x8 font as the original, but that's not always the case.

EMS can be nice for some things. A 386 can simulate it through EMM386, but hardware EMS is always faster.

Memory expansion card may be an EMS card. If so, the RAM on it wouldn't be counted at startup, just by programs that used it.

You're not going to damage it by using it, and even if it did stop working, it'd be worth probably almost as much money still.

Pros and cons. 32-bit is faster to process since it aligns with memory locations whereas 24-bit does not. However, 24-bit takes up less memory (1 byte per pixel color less) but more procssing is required to transfer data. Did any VGA manufacturer employ a clever trick of transparently translating …
Re: XT is 8088 IBM clone, SRAM in ROM slots?

There are 8088 systems with SRAM already, the IBM 5140 Convertible used it. That said, I would love to see what a V20/V30 system would look like when pushed to the limit with SRAM and frequency increase.

It's a miracle that this setup even boots and isn't completely clobbering the data and address buses. It's definitely placebo and I wouldn't suggest running it like this for long. It's not acting as cache because not only does your 8088 system not have cache control circuitry (None of them do), I …
