I understand the Apple RAM upgrade for the IIc won't work in the IIc Plus unless I replace the PAL chip because of a timing problem. Where do I get the replacement PAL chip?
There seems to be a rumor that later IIc Plusses were sold with a 256k RAM expansion installed. Where did this go? Where can I get one?
This may not be the exact reply you are looking for. But as I understand it, the //c rom 3/4 and //c+ ram expansions are pretty rare. And the only modern replacement I know of is from a2heaven. Which from my experience is once something is out of stock there, it rarely if ever comes
back into stock.

True, but they are occasionally available, and I know where I might be able to get one. I want to make sure I can use it first.
Is that your //c LED screen?
Apple ::c Prairie Portable Power Pack.jpg
It's mine, an Apple. I got it for $15 at a second hand store in the 1990's. I guess the're a little more than that now. Your C-Vue looks very similar, exept where it's hinged. Apple displays fold down backward. I that a third party case?
Yes, that is the Prairie Powerpack System sold by Roger Coates out of San Diego, who also sold the C-Vue LCD screen and even would add backlighting to it (for a then unreasonable price, but I am sorry now mine does not have backlighing).
The Case came with a 12v rechargable battery pack (seen on the left) that connected through the DIN directly to the back of the //c for portable power.
I, of course, added the 3.5 floppy drive, which fit nicely in the middle of the Pack, after removing the C-Vue and putting it in its pocket on the back of the top part of the case, and turning the //c sideways.
In 1988, I brought it with me for work to the Cannes Film Festival with a 1200 baud "pocket modem" and //c serial cable and used it to send files back to the home office's 24/7 bulletin board.
I also have Applied Engineering's Z-RAM board installed for extra memory (primarily for Appleworks) and CP/M for WordStar and DBase II.
