Bringing a Rolodex REX-3 back to life

About a year ago I came across an Amazon store selling what seemed like "new in box" Xircom / Rolodex REX-3 organisers. I'd always wanted one of these ever since seeing them advertised in Popular Science back in the early 2000s, so I figured for $35 I'd take a punt and see what turned up.

What eventually arrived was a complete REX-3 kit still sealed in its shrinkwrap, including the RS232 docking station, original leather wallet, software etc. This then sat on my shelf for about 12 months until I remembered I needed to buy some batteries for it.

Upgrades tonight

We're starting some upgrades tonight. Things could be bumpy for a few days.


Apple ][ out of memory

Apple II Plus system board without 16K Language card boots correctly.
Ctrl-Reset give the flashing prompt.
Even typing HOME returns an out of memory error.
Installing known good 16K Language card computer boot normally
but when typing HOME the screen goes to gibberish.

I know memory issues with these old critters can drive you into the nut house.
Any idea on where to start?
