In reference to ''John Titor'' and the 5100 - the "IBN 5100" had a leading role in the time travel anime series "Stein$s gate" where the 5100''s APL code was needed to translate the evil ''SERN''s time travel logs. Really good anime BTW.

Last time I looked the Smithsonian had the development prototype of the 5100. It was called Scamp or Mercury, depending on the phase of development. The one at the Smithsonian was made of wood and had a nine inch screen. It was given to them by Dr. Paul Friedl, one of the early inventors at the IBM Scientific Center in Palo Alto, California.

This is the computer time traveler John Titor claimed to have retrieved in 1975 traveling back from his time in 2036 to help rebuild their world.

Some asked about PALM. It stood for "program all logic in memory." I recall it as an 8 bit machine, though.

Wow, I worked on one of these in 1982-83. It was unused at the time. It had been bought by the lumberyard where I worked when they were flush with cash after the snows of 1978-79 caused a garage building bonanza. I taught myself BASIC programming on this thing and wrote an inventory system. I never could get used to GW BASIC after using IBM's powerful code (GW BASIC was crap, as far as I was concerned).

The original cost of the system: $17,000 in 1979 money, about $48,000 today. The machine had 32K of memory total, for both the BASIC program and my code, two 8" disk drives and a 132 column dot matrix printer. Amazing...

a blast from the past. I used one of these to score a golf tournament, borrowed from the now defunkt IBM training centre in West London

Wow, does the PALM mean that this is a 16 bit computer. It looks a little too primitive :)

I remeber using a IBM 5100 at UCLA in 78. They had it set up in an office in the engineering building (Bolter Hall). Originally, the restricted for staff use only but no one in the engineering dept used it. By May 78 I was only a couple of us freshmen were using it. It was the only free computer on campus that support APL. I still have the tape I used, I wonder it is still any good.

There is an article titled "Welcome, IBM, to personal computing" in Byte Magazine, December 1975. This is very reminiscent of the "Welcome, IBM" full page ad taken out by Apple when the IBM PC was released. It probably would have been more appropriate for IBM to welcome Apple to the personal computer industry.

I used a 5100 back in 1978 as part of a High School interneship (I was 16 years old) with IBM and now I am 40 and I really want and need a 5100 with APL to play with to reengage my old adolescent pubescent memories
