... it wasn't until after I proudly had soldered my contraption to the board that I noticed that the DIL14 socket I thought I had used was still lying on the desk ...

In transit:
32.08 crystal
Video unf*ck board
Missing from the parts kit:
72LS02 - and it seems I don't have one in all of my 74xx collection. Will order.
- edit #2: Ah! Actually I have a bunch of 74ALS02. So unless it needs to be "slow" that should work ;)
Everything else I need to boot up populated now. What might be different from others is that I will use IMP DMA and Shifter.
edit: Ah, no, still need to steal an MFP crystal from one of my (all working) machines.

I had no issues with the IMP shifter and DMA, so you should be ok (famous last words)

Were you using a complete IMP kit? My GLUE and MMU are Ricoh

No just the shifter and dma. Emails now back in my Mega but still using the IMP shifter

First boot: Stable white 60Hz screen. Usually an indication TOS isn't executing or being held in RESET.
Not sure when I'll have time to debug, but, I do know I haven't soldered a reset switch to the board, thinking that it was only needed if I want to ... reset. Am I not thinking that through?

Reset switch shorts out a capacitor which then re-charges to trigger a reset.. so it shouldn't matter if there isn't a reset switch... you may need to up the value of a cap to 47uF (from 10uf) as I think icky had reset issues.
