You've got as many projects on the go as me!!!

Nobody has more projects on the go than rubber_jonnie...

Indeed. I only have one software one and one hardware one at the moment, and I've not really started the software one.

Anyway, on the lynx 96K front, other than the missing resistors all the passives and transistors are on the board except for most of the decoupling caps, over 50 of the blighters! I've modified the video RAM board so that it's compatible with 4164/41256 chips and hence doesn't need -5V and +12V.

There is one ceramic cap in the RF/composite circuit which is an unobtainium value, 56nF, which I've left out. I'm not going to use RF or composite out anyway as that needs +12V and if it's like the 128K I'll not be able to get a stable chroma signal anyway.

I'm also leaving out the UART as I don't need the serial port.

Once the resistors turn up and I've got enough decoupling caps in place I can start scavenging parts from the 128K board, such as the main crystal, and start getting the board ready for a first test.

Sounds promising, and getting rid of the 4116 is always a good thing.
