- the 250425 board should in fact boot to the familiar blue BASIC screen just fine without U1 and/or U2. (However, with U1 gone, e.g. the keyboard obviously won't work and with U2 gone, e.g. the serial port won't work).
TODO
- Check VIC-II Vss is 5v
- you're looking for the RESET line to be grounded for half a second during powerup.
