41CL: Second set of Main RAM

[Ángel Martin]

Forgot to mention that this is also the perfect method to recover from a MEMORY LOST event: simply swap the Main Memory and your lost configuration is back on line.

Another method to "prime the pump": instead of using MMCOPY you can simply copy the RAM block at 0x800 into 0x081. This is faster but does both main and extended memory - thus not so specific.

with "800>801" in ALPHA, XEQ "YMCPY".
