Dual function ROM sockets on the C128 - Repurpose the abandoned BASIC ROM socket

This is a quick and dirty mod video for hacking an extra ROM cartridge internally to the C128 flat or C128D (not DCR).
A while back we consolidated the Kernal and BASIC ROMs on a C128 flat down to two chips. What to do with the now empty ROM sockets? Let's add some bodge wires, a few diodes and a resistor then put a function ROM in it :D

If it's open collector then no diodes are needed. Just the pull up. Open collector outputs can be tied directly together.

now with this mod working you need a zif socket in u33, so you dont destroy the board or rom when removing the rom from u33

[@Malcrom1967]

Just purchased a C128 and the board has some water damage. Would you recomment transfering the components to a newer Neo board?

[@retrotechinsanity]

Absolutely, the Neo board is excellent!
