Hey all of you,

I would like to inform you that the video link is public! :D I want to really appreciate XavSnap for producing a potential board to fit onto the cased computer. Furthermore, I want to know your opinion on this project. And share it with XavSnap.

Successful!

Thank you very much in advance.

Cheers,
DesSony

Hey all of you,

We already know about the result with the ZX81 and TS1000 cased computers. Now, behold the TS1500 cased computer result!

XavSnap, do nothing to the board! The EPROM/EEPROM already take control over the computer! :lol:

Hi DesSony,

The MIC socket seem to be masked by the PCB...

But, it's a good new ! (the PCB is track free in this location).

I'm pretty sure they didn't worry much about screen burn-in with this app. It will sit on this screen forever without someone at the keyboard.
