- Ah the memories!
-
- OSI did indeed have more than one model, including a rack mount version
- that included at least two processor boards, one with a 6502 and one with
- a Z80 cpu.
-
- I own the C1P series 2 which came in case that made it look like an Apple
- II. It was the Amiga of its day. At a time when most "home" computers
- were a group of circuit boards tied together with ribbon cabels,
- containing 1 or 2 _k_ of ram, and using old(even then) teletypes for I/O.
- The OSI came standard with 8 k of ram, and Microsoft Basic in rom, had a
- built in keyboard, and video output ready to be hooked to a tv set. Mass
- storage was through an audio cassette recorder. Most programs took 10-20
- minutes to load the 8k or less of data.
-
- Unfortunatley, like the Amiga, it was far enough ahead of its time that
- most people couldn't see the value. The company went through much of the
- same troubles C= did later, being sold finally to a company mainly
- involved with microwave communications devices, and shortly disappeared.
-
- Thankfully, through the efforst of peopls such as Dr. Kittel the furture
- looks brighter for the Amiga!
