TT030 issues

Post by Dlfrsilver »

Hello,

A Guy posted about his TT030, and he gets this on screen :

IMG_2591.png
IMG_2591.png (402.69 KiB) Viewed 991 times

For me, it's either a TTL fault or a RAM fault.

Anyone has a clue on what the problem can be ?

PS : the screen in itself is not faulty, it works with another ST.

Thanks for any input.

Probably a RAM fault.

The shifter is picking up the wrong screen mode so the display is in TT-High but the data in TT-Low mode. It's also crashing with a lot of bombs.

P.S. You should have attached the photo rather than linking to it as those are board rules.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Thanks a lot for your explanation.

The trick is to just add the picture as an attachment and then put it inline.

I have sorted the picture out in the original post. In case you wondered how it got there.
