the copy from device address is relative to the device. if you have a 2k
device, then your answer would have to be between 0 and 2k-1 (or a copy
would make no sense).
you have to supply size if you don't supply 0 as an answer (to keep from
reading off the end of the device.)
the ram address allows you to skew the read to somewhere in ram other
than aligned with the device address. again, you need to be aware of the
size of ram to keep from writing off the end of the ram.
if I recall the unit I had could do 2764's in one pass, so had 8k bytes
of ram.
if you had to do a 27128, you would do two passes.
copy from device 0-8k to ram 0-8k program at 0 to 27128
copy from device 8k-16k to ram 0-8k program at 8k to 27128
a 27256 took 4 passes, and so forth.
I had both 29a and 29b's and this sort of thing worked for both,
whether with unipak or later version.
