Hi,
I just picked up a Mac 128K with a Mac Rescue upgrade installed. From what I understand, this upgrade adds a SCSI port, allows up to 4MB of RAM, AND supposedly provides up to a 2MB RAM disk.
The original 64K ROMs have been swapped out for 128K ROMs, and the internal floppy has been upgraded to the 800K version. I wasn't able to boot from the internal floppy (probably dirty or dead, at least it ejects) but was able to boot up of an external 800K floppy drive.
The SCSI port has been installed in the battery cover area.
My version has 1MB installed, but it appears to take standard 30pin SIMMs. There are a total of six slots, with four currently occupied by 256KB SIMMs. I'm guessing the two empty slots are for the RAM disk?
Has anyone ever used one of these upgrades? Are these at all rare?
