My father bought it from Saudi Arabia (where he had a civil engineering job in 1982) for me when I was 12 years old. I learned my first programming language, BASIC, on it. Astoundingly enough, 30 years later, it is still the best calculator I''ve ever owned and I still use it. In 30 years, I''ve replaced the batteries twice or three times I think. It is truly a marvel. Who makes technology these days that''ll last 30 years?

My first computer, taught me programming when I was 8 years old. I ported lunar lander from ZX Spectrum to PB-100 when I was 9 yers old and only now I understand who unbelievably cool that was, I just wanted to play the game back then.

Now I am a CTO, this computer made the programming my lifestyle!

My first PC, I recall two things, a blackjack game crammed in the 544 bytes.
And a regularity race among friends where the actual average speed was kept by me using the pb100 as a mere calculator.
The first leg we had 30 secs margin, and the guys with 10 secs margin taunted us. They simply lucked out after that, so we won all the other legs. $P

I had one of these with a dock for a tape recorder to store programs. My brother still has it and it works perfectly still

One could attach a thermal printer FP-12 to it.

I got mine as a Christmas gift in 1982 or 1983. I was about 10 at the time and learnt to program in BASIC on it before moving on to a Commodore 64, two or three years later. I still have it in a box somewhere. Great memories!

I bought mine in 1983 and loaded it with navigation programmes for off shore-sailing and later used it until 1989 for scheduling transport services. I dug it up again after we moved house, put a couple of new batteries in it and its away working again. All I have to do now is find the book and manual and I''ll have another to play with.

I bought a PB-100 from a Truro charity shop in about''85 and it became the fun thing to mess about on whilst in college. I even bought the or-1 later and managed to write a very simple arcade game using / and $ and _ characters together with $ for the main craft.
Unfortunately the on/off button lost coherence one day and I never managed to fix it. It eventually got taken apart and binned but the fond memories still linger,

It was on one of these that I learned to program in Basic. With the added memory chip ( extra 2K IIRC ) I turned it into a Pilot Nav Computer.

In the UK Clive Sinclair then brought out his ZX and Spectrum computers and we never looked back.

In 1992 a guy, who had braught it from abroad, sold it to me. It was helpful to write some programs for routine calculatings at school. Then I forgot it for years, meanwhile it survived a flood...
Now I gave it to my child for school computings. Maybe teaching her a little programming and playing with mp3-player as a program saving destination as I have a docking unit also.
BTW, any RAM Expansion Pack for sale? $)

Got one in 1984 ! Learned programming on it and used it for a couple of years before I got my Commodore 64.

It was small, but you could actually write some very interesting code with it.

still have it . it's in poor condition after 5 years of programming during my school period . 0.5K where not really much but I manage to run several program for electronic calculation . good time goes by

it had a 455kHz ceramic resonator that was used as system clock!
