you can see...

ACIA: it can be also the Rokwell R6551AP
I can supply the PLA.
I can supply the CPU replacement 85MC01 (it's a C-Mos so it can't perform illegal opcode).
A specific N-Mos version is under development but is not ready, so if you have also a C16 you can use the C16s CPU on PLUS4 and use my "CPU4C16"replacement in your C16.
See also if you are interested in my other projects, because unfortunately we are on the opposite side of the world and the shipping cost could affect, so I can certainly be convenient if you need more items.
Contact me for details
And now......
the "CPU4PLUS4", a processor replacement for PLUS4!
It's essentially a "CPU4C16" shaped for fitting the PLUS4 space...
Another good point....
A C16 "plug & play" modify (without use of solder iron....) that allows:
1) 64K S-RAM expansion
2) jiffydos switchable with a simple "SYS53240" (no holes on case, no wires to motherboard)
3) TV standard (PAL/NTSC) switchable with a simple "SYS53245" (no holes on case, no wires to motherboard) (the starting TVstandard is jumper selectable)
