Title: 6504 Microprocessor (basis of the Floppy Disk Controller)
Post by: sigma7 on September 26, 2023, 04:57:01 PM

The Floppy Disk Controller on the Lisa I/O Board is based on the 6504A microprocessor.

The 6504 is a variant of the very common 6502 microprocessor used in the Apple ][ series.

The 6504 is clocked at 2 MHz, so the 6504A speed grade is appropriate.
