Thank you all ! :-)
Pretty sure you would sell a lot if you made "modern" fix on that design.
It is not my goal, my only goal is to make me happy :-) My electronic realisations concerning the TI-99 will never integrate modern component. If I want to use modern tecnology, I use my Intel Core i5 iMac, Macbook Pro or PC computers.
Like someone said, more ram, memory card options,
It is panned on the next version. The v1.0 was made to validate the good operation of the Tiny99/4A computer according to the (numerous) corrections I made on the TI-99/4A schematics that are false. I took the opportunity to bring some improvement to the TI-99/4A like size, speech, 32Kb RAM, RGB signal, expansion possibilities and speed.
Is there going to be thermal issues with such a compact design and old components?
No thermal issue :-) I use the TI(ny)99/4A during many hours per day without note abnormal hot temperature. Even in turbo mode.
