I would really look at using a Premium capable Basic such as the latest 6.35e to be compatible with everything.
Oh boy. I'm on the home straight with 6.23. I guess there won't be too much difference to use 6.35e.
Let me get 6.23 stable and then i will pivot to 6.35e.
My emulation model is PC85, does 6.35e work, or do i need to look at telecomputer hardware?

In someone's opinion the manuals don't explain it well.
Someone treats the DRAM on a 128K machine as four 32K banks (0-3).
All banks can appear at the memory map at 0000-7FFF and are selected by using the nominated bank select register bits (output port).
Bank #0 is the only bank that can also be at address range 8000-FFFF.
The other options such as VDU address, and ROM option bits are used to punch little holes into the DRAM (Bank #0) at address range 8000-FFFF.
ahhhh, thank you, you've cleared up a bit more confusion for this BASIC fanboi!!!
