Old Computer Systems

A horizontal ribbon.

Introduction

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.

Restoration

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.
