Old Computer Systems

A horizontal ribbon.


This is the story of my continuing attempt to bring to life the old computer systems that I have saved from land fills everywhere. I find the older machines far easier to understand and work on than the new ones - but I work on and use the new ones as well.


This is an explaination of how I attempt to restore the old systems.

Intel Computer Systems

This covers the Intel OEM Single Board Computers which I have running the CP/M-80 Operating System. These machines will not run ISIS-II. They are Multibus-I systems.

Intel ISIS/MDS Systems

This covers the Intel Microcomputer Development Systems (MDS) Series I-III. These machines all run the ISIS-II operating system. They are Multibus-I systems.

S-100 Bus Systems

I began dealing with the S-100 Systems in 1978. I still have my first S-100 System and it still operates.

IBM PC Systems

I began with the IBM PCs as soon as the first clone board (MPX-16) came to market in 1982. I have fiddled with them off and on for the last 35 years.

Software for the Old Systems

This page contains links to the old software that has been found and runs on the CP/M-80 and ISIS-II Operating Systems. This includes the Operating Systems and the user software.
