Retro Challenge - 2015/07 - Day 5

Installed SD Card

Dismantled the Compact and installed the GoSDC into the ROM slot.

TV Display

Tried to power the small TV display from the machine but found it requires 6v. Going to have to add another Step-Up to the power board to provide the 6v it requires.

Update: Wired in the extra Step-Up, Adjusted the voltages on the Step-Up boards so that one is 5v and the other 6v.

Connected the power board to the BBC externally and checked that everything works ok. Board is powering the screen, Gonbez board and the BBC from the battery.

Then tested the TV board, connected to the external video out and got the following.

You can just about make out the Acorn MOS and the command prompt. This looks better in real life the camera doesn't do it justice. Next step is to get it to run something on the screen.
