Interesting Video: Sharp PC-1270

[Jeff_Birt]

Hi all,

Bob sent me an email about this thread which finally got me motivated enough to work past the registration gauntlets (Captcha and quiz). (I understand their importance in keeping bots out though.)

Sharp made a few 'run only' models including the 1270. It does seem quite odd from the view of a pocket computer enthusiast, but they did provide a simple solution to a point-of-use computation niche. I thought it would be interesting to try and figure out how to get a program into one.

I did find a bit on information on the PC-1270:

For last link look for PC-1270 section as well as "Languages" section.

On the PC-1500 front, I came across the address of 'Pygmy Computer Systems' in Florida and given the date of incorporation was 1 year before the ROM cart was made it seemed likely to be the same company. The registration address is a private home though. I sent a letter via snail mail on the off chance it might lead to more information.

The personal notes that came with the PC-1500 lot was the most interesting. Things like program listings with a handwritten not "Why does this lock up?". There was even a written response to a letter he sent to someone asking for help with a program.

The PC-1500 is my favorite machine of that era, I think. In recent months I have written a lh5801 emulator (processer in PC-1500) and am working on a disassembler for it as well (which I'll back port into the emulator for disassembly on the fly as you run code.)
