I've got a 286-12 system with the VLSI chipset that's rated for 12MHz. It runs the ISA bus at full speed. The oscillator is soldered on. I was toying with the idea of taking the system all apart, desoldering the osc, socketing it, and experimenting with faster ones. The actual desoldering would be trivial but taking the board out of the case would be a hassle, and the only other oscillator I have on hand would push the CPU and bus all the way to 16MHz, so it would probably mean buying oscillators too.
Is it even worth the effort to try? What are the chances that my ISA devices (AHA-1542B, 3C509B, ET4000, UMC multi I/O) would even tolerate a faster bus speed? I have the original intel 12MHz CPU as well (socketed so it could be changed, but again that would require another purchase) and it gets hot as hell already.
