Where is that one located on the 2019 board? In case it's the one that goes to the 22v10 GAL or the KS156, yup I did fit those.
I've got 2018 edition PCB. Did you get yours PCB from Pavel Raybcov? Do you have circuit diagram for that machine?
Yeah, I got the PCB from him.
I'm currently working with the original Turbo+ schematics by black_cat (the one with the epm plds and prom).
Anode of SMD diode connected to 24 pin of CPU (WAIT-), stil can't trace link for cathode, seems to be VD2 КД522 on diagram. Try to check yourself!
That will be connected to one of the 22v10 GALs (the one programmed with turbo.jed)
This is incorrect, it should be a BC557 (PNP just like KT209)Цитата:

Sorry, it's my mistake! Fixed it.
so ... what would be the best way to get a classic GS PCB (not NeoGS, not the one by Micklab)?
