I am looking for drivers for Buffalo 286 to 486 CPU upgrade models that start with HRX.
HRX-12S4-A
HRX-C12Q
HRX-12T-A
HRX-C12T
I have cpupc, eupc, ex_140, hk6_220, and hm2_120 files. They are for all different models. I have also tried the IBM and Kingston SLC2 drivers.
If anyone has one of these, if they could let me know how they have it set up and what drivers for them.

Had it work once with loading through DDL and I don't remember what driver. I get an error with CTChip34.

It was using DDL load REVto486.SYS. It is unstable, though.
