RE: Returning to the HP fold
Firming up my collection plans.

I want to 'flagship' (my term) my HP41CX. It is already modded for 2 speed operation, so that is out of the way (also found an article about SOS and it seems they didn't do speed up mods, so I probably won't ever find out who I had do mine)

Also, I've found pictures and descriptions of internally mounting modules, and I've also found a chart of how the port addressing works and how the 41 'knows' upper and lower ports and how many goodies can be in each port electrically (they can be wired to appear as connected to whatever port I decide.

So, I can internally mount a pair of XMem modules and keep the physical ports open for 'stuff'.

I've acquired a nice looking/working card reader, revision G, so that piece is here. The XMems should turn up soon. I'm going to see how I like my pretty much unused ZenROM, if it passes muster, it can be internal to the CX, and wired to appear to the processor as being in the upper card reader port.

My PPCRom will remain a free agent, and spend most of it's time in the port above the card reader. Port 1 will be the 'guest' ROM port and port 3 is for HPIL or the IR module (yeah, got one and an IR printer)

That configuration leaves port 3 upper unused, and on a 'flagship' that's not allowed, so looks like my Extended I/O might get installed internally in one of my HPIL modules. The obvious choice is the one I think has a frayed wire internally on the in or out cable. I'll see if I can do a 'transplant' and an internal XI/O install. That job is not high on the list, LOL.

I finagled a 41C, thinking it would be my take it with me and use machine, but the one that turned up is really nice looking. Really nice looking.

I'm thinking donor body for a CL, bwa ha ha ha ha!!
