How to make PCjr Nicer:
Cartridge slot Blinkenlights ! Miniature version of the Legacy Expansion chassis front panel: https://www.brutman.com/PCjr/pcjr_legacy.html
Cartridge PCB with a few 74LSwhatever buffer chip, resistor packs and LEDs ! Lots of LEDs, visible from the front for:
A0...A14
D0...D7
And maybe CS3...CS7 behind an inverter ? Will CS6 & CS7 LEDs light up whenever the on-board BIOS ROMs are accessed ?
All of them blinking whenever the PCjr is doing something.
No L-trace for the A02 RESET pin so it can be plugged and unplugged "hot"
Useless but nice
If A15...A19 would have been available on the Cartridge connector, a nicer one with LS138s and LED bar graph could have been made to show which part of the memory is being accessed.
