v3 rom: use system disk/system tape ver 3a, 3b or 3d
+D G+DOS versions:
a v1 (-non a) exists but has yet to be found/dumped,
from "pick-poke-it" user manual:
The rom/system disk versions must match,
v1 rom: system disk/system tape ver 1
v1a rom: system disk/system tape ver 2a
+D only curiosities:
The earliest v1.0 unit has a very crude pcb (no solder resist or silkscreen markings),
has various rework modifications (cut tracks, flying wires, piggy-backed chips etc.),
the PAL is a 16L6 rather than a 20L8 used in later version (only known dump is bruteforced and converted to gal20v8 target.)
details here: https://web.archive.org/web/20171118171054/http://trastero.speccy.org/cosas/JL/PlusD/PlusD-v1-0.html
from "pick-poke-it" user manual (reguarding v1.0 unit):
"A few PLUS D users are still using Version 1 of the ROM which was used in PLUS D's sold in December 1987-January 1988.
... check the serial number on the bottom of your PLUS D. If it's a 4-figure number commencing with 1,
then you have a PLUS D with the Version 1 ROM."
