Extended Basic and bitmap

That said, I would be curious to know what would be needed to be able to *completely* restore the XB environment upon return from bitmap so that one could continue using XB without chaining another program.

I'd guess you'd have to save/reload, PAD, PC, ST, WP, VDP REGISTERS, all 16k of VDP(only takes about 1 sec. w/TIPI). Probably faster to/from SAMS memory.

Yes I can confirm its faster with SAMS. I guess roundabout 0.3 seconds

I would have to use the SAMS to save the whole of VDP since there is obviously not enough room in low memory for that unless there is a way to access upper expansion memory for storage...

What would you recommend as references for SAMS use? I've never explored that device even though I've had one for a very long time...
