Peaksoft Prestel Cart (probably) ROM dump

[tjewell]

I'm pretty sure I've found one of these Peaksoft Prestel Cart mentioned here: http://peaksoft.co.uk/peaksoftstory/, or a homemade version of one. Certainly, there's a copyright message "PRESTEL SOFTWARE MARTIN CLEGHORN MULTITERM1987 1.1" in the ROM, and that ties up with the story on the Peaksoft site.

The attached ZIP file contains the ROM dump, plus two pictures of the cartridge itself. I would really love to see a manual for this, to see if I can actually get it working!

Cheers, Tony

Nice find!

It would be nice to find a way to feed the cartridge with some Prestel data.

Can you be bothered to scan or otherwise take some nice pictures of the cartridge and the PCB?

Actually, relatively speaking, it shouldn't be too hard. Once I can figure out what baud rate it's talking at, I'll get it to connect to a Pi or some sort of wifi232 box, then I can use a service like this - https://glasstty.com/wiki/index.php/The ... tex_System

I'm happy to get photos of the board if I can get it out - it's jammed in real good! (the switch makes it tricky) I'll give it another go when I'm next in the office.

Hi Rob,

Well, I got the case apart, and this is what I found inside. Is this picture good enough? All I see is thousands of little green wires and it's making my head hurt!

Cheers, Tony

Hi Tony,
nice find, despite this wire-wrapping mess
Thanks for sharing!
I am afraid that creating the schematics would be a pain ... unfortunately
cheers
