Glen Deas sent me an article about the Ziptape cassette interface, 1978, by the late Lew Edwards. Glen made a PCB for it.

The article about the Fast Cassette Interface is part of my CW Moser Assembler/editor package. Scanned by me in 2010 to the file kimfastcassette.pdf and on my website with the CW Moser package for years now .
Glen Deas knew it was designed by Lew Edwards and entered the source in modern assembler format.

The core routine of the disassembler is the well-known Steve Wozniak/Allen Baum 1976 article A 6502 Disassembler from Apple
The program is a TTY program. I build it with the then current hardware and software of my KIM-1:

• 32K RAM from $2000
• Video terminal uppercase 24×32 on the KIM TTY serial in/output
• A parallel ASCII keyboard connected to the second 6532 RIOT port
• A serial connected, at 9600 baud, Heathkit H14 matrix printer
• Dual audio cassette records under motor control
• MICRO ADE assembler/Editor, extended and with video TTY as output, parallel keyboard as input and could print at the H14 printer

My KIM-1 came as an Rockwell OEM kit. The Rev F board is made by Commodore MOS Technology, the packaging and manuals are the original MOS Technology books, but Rockwell branded.

The logo on the KIM-1 is covered with a sticker, of course to have the Rockwell logo on the board. But some one was so clever to add essential information and addresses of the KIM-1 monitor.

Guido Lehwalder gave me photos of his KIM-1 Rev A. Thanks!
Note the different colors of components.

I added these to the KIM-1 Revisions page.
