Hllo Nitro: Mr. Pix : "So, I have successfully upgraded a non-turbo slab so it boots 2x quicker by replacing the 53C90 with a 53CF90A. All accesses are 2x faster if the drive supports fast SCSI."
I'm not sure if 53CF90A are the same chip as the eBay NCR 53C90A ? As I know the drivers and bios is finicky ... it is a good price though.
Mr. Pix says he has a few spare 53CF90A so I may just see if he will send a few and I'll try his mod with Matt my Capacitor Guy behind the soldering it would be a very coo upgrade:)
