I am in need of the hyperdrive software that came with the upgrade. The software for formatting and using the hard drive.
The hyperdrive was a hard drive upgrade for the 512k Macintosh. There are a few models. One with 10MB, another with 20MB, and a third which upgrades the processor from 8 to 12MHz, adds a math co-processor, 2MB of ram, and a hard drive controller!
The strange thing is, this is not a SCSI upgrade. This upgrade uses drives called MFM by many, but really called ST506. Old IBM XTs used those hard drives.
I have the 2MB model with hard disk and a hard disk only upgrade. I have no hard drives that came with the computers, but I do have old compatible (I hope) hard drives.
Any information would be much appreatiated!!!
