Hi,
I recently got a "small" Hobbit clone (the one without FDI) ... is there a schematic available?
The machine works, but the screen is shifted to the bottom right and some data is decoded to the border, I'd love to fix that.

1.sorry. This option is probably no circuit. robes and the hobbit are related computers. but the schemes are a little different in the 556rt1 chip.
2 I don’t remember which version of the computer I have, if I’m a “hobbit” I can consider this chip, and if it is robi, then I can’t blink anything
