Telestrat failure?

[Symoon]

Thanks to Thierry that checked that my Telestrat boards and power supplies were OK, and René that lended me a working cartirdge, I've been able to boot a Telestrat

It appears that I tested with two cartridges: HYPER-BASIC (left) and TELEMATIC (right).
But if only one of the two cartridges are fried (even if the Telematic only), the Telestrat doesn't boot. So actually I realised I have more working cartidges than I thought, some HYPER-BASIC are working alone, and failed to boot with a faulty TELEMATIC.
So that's good news overall

Great to hear! I've got to do the same with my Telestrat sooner or later ..

Well, I've tested all my cartidges.
- Hyper-Basic: 3 OK, 2 failed (one being currently being revived by NightBird)
- Tele-Ass: 1 OK
- Stratoric: 1 OK
- Telematic: 3 failed, 2 apparently OK but not sure they do anything: with or without it, I still see "ROM 32Ko" instead of "ROM 40Ko" as displayed in Euphoric (Telematic is only 8KB big)

So it seems the Telematic cartridge is actually the one failing massively here.

Does anyone know if it should indeed add 8KB to the ROM amount displayed at start?
