@metin First personal computer I touched in 1980 was a #Micral (80-20?), thanks to a high school professor that gave me access to one
https://en.wikipedia.org/wiki/Micral
Then I had several #Sharp computers, a #pc1211 that my father bought, then temporary access to a #pc1500 (with small plotter!), #mz80k and #mz80b, thanks to a Sharp reseller (Mr #Laussucq, in #Dax).
Got my first #ibmpc #Thomson clone in 1983 or 1984.

Oh and if anyone is wondering why the TO7 and MO5 beep annoyingly every time you press a key, I think it's because the first TO7 model had a horrible rubber membrane keyboard.

The MO5 was still horrible but a bit less so I guess 😅.

Subsequent versions/models had proper keyboard.

The thing they didn't have is a backspace key. Sooo annoying to have to do it in two steps (left arrow, delete).

Backspace, what a concept!
Kids, don't take it for granted!

The Thomson TO7 came before the MO5. Whereas the MO5 had a gate array for video, the first TO7s did it all with discrete logic.

Also two IO chips, why? Well, they wanted a timer (for flashing the cursor and tape IO).
They also needed extra ROM because the OS didn't fit in 4KB.

The MC6846 PIO chip has 2KB of ROM. It was designed for "2-chip computers" e.g. CPU + MC6846 (ROM + IO + Timer)

So 6KB ROM. Not enough for BASIC. So put it on a cartridge.
Or how about LOGO?

#hotkeyEmu #Thomson #TO7

Crap, there's another IO/timer chip.

Oh, fun! A rare io chip with next to no technical documentation.
Well, forget about it.

I mean I'm doing this for fun.

Ok, I found a bit of info here and there.
Maybe even enough to implement it.

Would be a lot of work for only this computer.

But I've done IO and timers before.
They're not very fun
But...

...

Fine, I'll do it.
Shut up brain.

Lightpen - check! OK it reacts on black, which it isn't supposed to do (and red too according to the docs). But it'd be surprisingly annoying to fix. I'm not kidding. There are reasons and everything.
Maybe one day. Or not.

Maybe I could do the TO7, now? How hard could it be?

*checks docs*
Ok, different memory map, not too bad...
I can reuse some components and the video is very similar.
Keyboard decoding is a bit different.
Sounds doable.

I hate light pens.

Thomson loved light pens. Came stock with all their computers. Even had a BASIC command to read it (INPUTPEN).

The CRT monitor scans from left to right in 64μs, line by line (312 lines), 50 times per second.

Due to persistence of vision we see a solid image but a phototransistor right on the screen would see a "dot" blinking on and off 50 times per second as the electron beam zooms by.

I'm no expert, but that looks like a Thomson MO5 running* BASIC on my very own 6809 CPU :meow_party_bounce:

(Yes it beeps annoyingly every time you press a key. Really.)

*no light pen, no tape, no floppy, just BASIC, but still. I think it's neat.

@timlocke No idea about #Thomson; they were pretty much limited to France? And the #TI chip… I agree it’s got good colors and the games show it, but I’m having trouble finding any troves of *art* done with machines that used it like the TI-99/4A or #ColecoAdam.
