Alternative HP-41CL mainframe (OS ROMs) update for beta test

[mfleming]

A minor addendum to the setup instructions. I found I had to do an UNLOCK for pages 0 to 3 before the PPLUG would work. I've also backed up the extended memory to RAM, just in case

Code:


"800>840"  YMCPY   ; May or may not be a good idea!
"801>841"  YMCPY
"802>842"  YMCPY
"803>843"  YMCPY

I'll do the same for the patched O/S XMEM registers to 844-847. Once done, perhaps a pair of O/S switcher programs for housekeeping?
