Re: 3 (+3 more) retro battle stations

@CoffeeOne Cool. My favorite Symphony Haydn 486 board. Looking forward to see what you derive from yours. Will be interesting if it matches my early findings. These are too rare to be Dell related. I cannot remember how big Dell was at the time - let's say 1995. Inclined to think these boards are …

The military graded 8087 chips, prefixed with MD/ML, are not great. But that opinion is based on a single chip i have. The error can be large, so keep that in mind. 8087 FPUs get very hot, but simple heatsink+fan take care of that to a large extent. Speaking about room temperatures here of course. …

Re: 3 (+3 more) retro battle stations

It was established early in the thread which are the best 72-pin FPM/EDO RAM modules for peak 486 overclocking. Results were validated by other forum members to hold true. At the same time, despite the plenty of noise around 286 and 386 hardware, the RAM related details were mostly left untouched. …

Re: 3 (+3 more) retro battle stations

Actually this is a great card, but for 8088/8086 machines. I would even state "the best graphics card for XTs". Here is mine: image If you test it on 486 or later hardware it is unimpressive. Evident from this benchmark with bunch of cards split by time period - early 16-bit ISA, late 16-bit ISA, …
