Am I correct in assuming that I have 16K of ram available to use
starting a=
t 0x4000? I would like to expand on the scancode program and
maybe try to g=
et forth running.

It appears there is at least one page of memory available.

have 16K of ram available to use
and on the scancode program and
Yes. Wh=
en mbug starts, it banks page #01 of RAM
into slot4000, so unless you chang=
e it, it should
still be there.
Mbug does not use this for anything itse=
lf, it just
puts it there as a convenience.
The mailstation divides the =
64 kByte z80 address space
into four 16 KByte regions, which I have been c=
alling
slot0000, slot4000, slot8000, and slotC000.
The pages of ram, code=
flash, and dataflash are also
16 KBytes. The mailstation has 128 KBytes of=
ram,
ram pg #00 thru ram pg #07.
Slot0000 is always codeflash pg #00, and=
slotC000 is
always ram pg #00
Mailbug command "6" will display the curren=
t inhabitants
of slot4000 and slot8000, the two "bankable slots".
