I had the following home/hobby computers:
PDP-8/L in 1971
PDP-8/I in 1972
Wow... those were relatively fresh, then. My recollection was that a
PDP-8/L was $10K USD in 1967 or 1968. Any peripherals, or just TTY?
I had two DF32's and a TC08 and TU55 on the 8/I and used to run TSS as well as
OS/8. I purchased the 8/L and 8/I from "Sonny" at American Used Computer
located in Boston.
I got a lot of modules and I/O gear indirectly from DEC. They knew I had DEC
systems in my home - and would tell me when customers wanted to "dump" older
equipment. Most of the stuff I picked up that way was at little cost or free.
PDP-12 in
1975
Very nice. I've seen one up close, but never got to play.
I picked up the PDP-12 by purchasing it directly from DEC. At the time, I
worked at Fidelity - and was a large 11/70 user with RP04's, 9 Track Tapes,
etc. I ran the "quant" group and we used the 11/70 to do "bond arbitrage
analysis", "stock models", "portfolio analysis", etc. The PMs
(Portfolio
Managers) and Traders could access data/results interactively via terminals.
We also "sold" DEC systems to our corespondents (clients) with our "value
added software". So, needless to say, DEC "liked" me.
DEC sold me a "demo" PDP-12 for $3,000 when the list price was $28,000. I
later added an RF08 (dual disk - a whopping 512K of storage ;-), and a 9
track tape to the PDP-12. I also added two 8K banks of MM8I memory to the 12.
Subsequently, I sold the PDP-8/I and moved the TC08 and TU55 to the PDP-12. I
ran the PDP-12 at home for years. Other than "playing" with the it
(Spacewar!, etc.), I developed my own stock analysis software on the 12 to
help manage my personal investments. I few years ago, I donated the PDP-12 to
the Computer History Museum along with the complete DECUS library for the
PDP-12. (I was the last volunteer DECUS coordinator for the PDP-12).
I forgot to mention that in the early 70's I picked up a RPC-4000 (drum
machine) and restored it to "health". Around 1974 I donated it to a
Philadelphia museum.
Cheers,
Lyle
