Hi all,

I've got an IBM PS/55 5551-T1B that I'm trying to upgrade, it currently has a 386DX-20 and I'd like to upgrade that to a 486 of some kind.

It's a Japanese MCA machine very similar to the IBM PS/2 Model 70, so I'm looking for either a Cyrix DRX2 66MHz, an Evergreen rev-to-486 style device that plugs into the CPU socket, or an MCA card like the Kingston MCMaster.

Cheers,
Joudan
