Good evening and a friendly hello to everyone.
I have purchased an old TI-99 / 4a. Unfortunately,
I have a problem now. When I insert a Super Extended Module (Triton) and turn on the Ti, then very often the selection point 2 is not displayed.
Next time, only "2 S" will be displayed. Suddenly, in further experiments, "2 Super Extended Basic" will be displayed.
The TI returns to the title screen after selecting "2".
This process repeats until the TI hangs completely and this intrusive continuous tone is output.
I have / had another CF7A + module.
If I made it, that after countless attempts the TI does not hang up again with inserted CF7A + module (no CF card is plugged in),
then after a few attempts I have also made the XB module run a few times.
It also happens that XB was started, but knows about commands like SIZE, CALL INIT, and outputs syntax error.
If I insert the CF7A + with inserted CF-card at the side of the TI, then the TI simply does not run and it only different continuous tones are issued.
What can I do now? Is this TI lost and unrepairable. Is it even worthwhile to repair this board or should I try to find another one?
For tips I am very grateful.
