IBM 8 inch disk drive cabinet

The system came with both the monster IBM printer (not pictured) and an even bigger dual 8" disk drive cabinet."



The system also came with a boxfull of documentation and software.

I haven't had a chance to plug this beast in for testing and play yet, but I hope to soon!

Any information regarding the IBM5100 please send to me. This includes software manuals and potentially buying a IBM5100 both working and none working.

Thank you

(Cont. from #2 post) I am proud to have been a major part of it and outside of capturing and pillaging my beautiful, delightful and charming wife for 56 years mu experience at the base of personal computing in the world is my ONLY claim to fame. That is -- in my children and wife's eyes.. I retired from IBM in 1994 and have been employed by DST System since 1997.

(Cont. from first post) I had no partner and was solely responsible for the service planning for the product. I built all the training materials and planned the training roll-out. I taught the instructor force in the IBM General Systems Division education center. The product served IBM's need lead the industry in research and development. You might say that the public served as the laboratory while IBM figured out what the public needed. The team that built the IBM 5100 and IBM 5110 moved from Rochester to Boca Raton, Florida and built the foundation for the base of PERSONAL COMPUTING on the world stage.... the IBM 5150 from there it was, and still is a horse race. next post finishes my comments.

I was promoted into Rochester Service Planning from Dallas, Texas. I was an IBM Technical Specialist in Dallas and it was there that I installed the first IBM 5100 in the IBM Marketing specialist office. He was in charge of selling it. His name was Dean Frank and it's a long story but when I later was promoted to Rochester the SPR manager found out I knew the 5100 technically so he put me in charge of the IBM 5100 Support department. I had temps from the us service ranks in Rochester for US support. when calls died down I was promotedif you would call it that) to a course author and my product was the IBM 5110. continued in second post

Hi,

I am a very lucky owner of a 5110 basic only (no media, the disk cabinet was too big to transport from the us to europa, I will get this in the future however)and a 5100 full option, the 5100 video card got borked (the 5110 video card works in it, displaying chinese characters though :) Any one reading this that has access to or knows where to get parts please help me, I am in the process of backing up the basic/apl software that I have on tapes.


(Submitted June 16, 2008 21:17:16 by BobP)

My company bought the first 5110 that shipped west of the Mississippi and I programed (APL) it to program NC machines. Around 1990 I bought it from them for $33. (One dollar a KB plus a dollar profit) Soon after that I read an article on how the US govt. coded and decoded messages and realized that was what the APL language was probably designed for. It makes fortran look like a 4 function calculator.

Now I know that this will date me, but I was part of the IBM group that brought the 5100 to market. The hardware was developed in Rochester and the software by a 10 person team in Westlake Village CA. I had the responsibility of testing (QA) the software and then overseeing the development of the camera ready manuals at the IBM facility in Menlo Park(user and reference for both BASIC and APL). If anyone has a copy of these manuals, please let me know.

I spent a year working on one of these. I programmed an apartment management system for a fellow in BASIC. The model we had had 16K (5K of which was OS) I came within 59 bytes of using all memory on one of the programs -- I hadn't learned to modularize programs too well at that point.

APL was a most interesting language. Those who learnt it became quite addicted. Plusses - Very powerful and compact. Several pages of FORTRAN or COBOL or BASIC became only a few lines in APL. Minuses - Very steep initial learning curve. Special character set.

These photos bring back memories for me, as well. When I was in high school my father company bought one. I learned BASIC programming on it. I seem to remember it even had a rocker switch that was used to select APL or BASIC.

WOW! I remember that monster! I learned some APL (A Programming Language) on the good old 5110. I can not remember having seen my teacher so excited as on the day the 5110 was delivered. We had some real good times together exploring the secret system-monitor (found accidently when pressed pressed some keys while turning on the machine).

*sigh* these must have been the good old days LOL

Btw. Nice site. I enjoyed looking at some ancient computers i have known myself!
