Retro Challenge - 2015/07 - Day 31

More Wiring Up

Completed the various wiring bits that needed doing. Made a power board that connects the incoming power connections to the main circuits via a removable umbilical that can be removed to disassemble the machine.

Cut the circuit boards down to size with the Dremel and tied the cabling together with tape.

Glued the main power board into place.

Added in the secondary power board that provides the switching between internal power and external mains.

Connecting wires between the power boards.

VGA Output

Connected the VGA wiring harness to the internal resistors, found the ones I needed from the maintenance manual that has a full circuit diagram of the machine.

Testing the output. Works ok but there seems to be a weird problem with colours not working, the output is correct but everything on the screen seems to be white.

Power Switch

Fitted the power switch that allows me to turn on battery power.

Finished Machine

The machine pretty much completed.

Switched to battery powered mode. Screen is showing MOS command prompt.

Look no wires :)

Outstanding Bits

There are a few issues that I still need to resolve.

Firstly the VGA seems to not be displaying colour, not sure if it was just me or if there is an issue. Need to check the actual output on a real monitor to ensure that we are getting colours.

Battery needs to be fixed internally in some kind of holder so that it doesn't get hot from any chips on the board.

The original brown front has been removed, I want to get a new custom vinyl printed that will also cover the screen boarder. Didn't manage to get time to design and get it printed.

GoSDC is working ok but I'm not sure what I'm doing wrong as the patched ADFS and DFS won't seem to load.
Not getting any errors from it but the filing systems I've asked it to load don't appear. Going to try it in the normal master and see if its an issue with the Compact.

All Good Thing Must Come To An End

Well that's me done for this RetroChallenge. Looking forward to reading everyone else's blogs. See you all in the 01/Winter :)
