Really good anime BTW. author date text Alvin Ginsburg (United States) Friday 4th September 2015 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. author date text Fliver (United States) Sunday 1st June 2014 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. author date text Alvin (usa) Tuesday 19th February 2013 Some asked about PALM. It stood for "program all logic in memory." I recall it as an 8 bit machine, though. author date text Vicki Davisson (Phoenix, Arizona) Wednesday 30th August 2006 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... author date text Marcus (Earth) Saturday 19th August 2006 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 author date text Pharoah (United States) Thursday 24th November 2005 Wow, does the PALM mean that this is a 16 bit computer. It looks a little too primitive :) author date text Chuck Kaufman (Southern California) Thursday 11th November 2004 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. author date text Brian Bagnall (Winnipeg, Canada) Tuesday 22nd April 2003 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. author date text John Bajak (White Plains, New York) Tuesday 1st April 2003 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 /museum/ibm-5120 795 url date https://web.archive.org/web/20230405101343/http://www.old-computers.com/museum/computer.asp?c=795 2023-04-05

In September 1975, IBM announced its smallest and first portable computer (If you consider a 28 Kgs. computer portable, that is), the IBM 5100, no bigger than one of IBM's typewriters.

Developed in Rochester, it used the same operating system as IBM's /370 line of main frames. Thus it could accommodate the same APL interpreter, permitting the use of APL programs. A BASIC interpreter was also available, depending of the 5100 version chosen.

This was the first widely marketed and supported personal computer, and definitely the first useful all-in-one, portable computer system. However, it was a very primitive machine that was largely unsuccessful due to its high price tag (basic version costed $8,975) and limited expansion capabilities.

It had a built-in tape drive and a small 5" 64 character display. A special display mode allowed the user to select right or left bigger 32 chars. of each line.
The tape drive used a 1/4 inch DC300 tape cartridge and stored 204 KB of data.
The 5100 didn't feature a microprocessor chip, but a card called PALM (Put All Logic in Microcode) which acted as a 16-bit microprocessor.

Notice that the 5100 is the first serial number of IBM "Personal Computer" range that will later include the 5110, 5120, 5150 (IBM-PC) and 5160 (PC-XT).
