Seems like everybody is ditching their Intels, with new security issues found every day. I got into that mood as well and decided to retire another i386, a DX this time. Obviously it wouldn’t be any fun if it wasn’t soldered to the motherboard 🙂
And the replacement is a TX486DLC, another Cyrix in other words. I had to write my own cache configurator for the different memory map a full 32-bit Towns has, but I’m happy to report that both the CPU and the program work fine.
Benchmark results are pretty much identical to the 486 Marty, though this CPU doesn’t have a clock doubler so it’s still a 16MHz system. I know some people opt to change the clock generator to overclock it a bit but I decided not to. With cache enabled and possibly RAM timing tweaked it’s plenty fast for that machine already – twice faster than the 386 in fact.
I’m almost done shipping group 1 Phoebes so now I’ll have a week or two to fully dedicate to DocBrown. BTW, another Rhea batch will be ready soon as well, as usual watch the blog for ordering window announcements.
