Don't know where the 12K is going to - maybe
address space reserved for
Hmmm. I can fully understand why there's only 264K free in the base
machine (which has 512K RAM) -- memory is taken up by buffers, stack, the
'status' program, and so on.
But to loose 12K of every 512K for I/O buffers seems a little odd. Or for
extra page desriptors, or.... I could understnad if some memory was used
ot record the fact that it had a memory expansion oard fitted, but 12K???
and why is it pro-rata for the amount of memory added?
I/O - but I have to say I was extremely impressed by
the upgrade -
almost exciting reading!
I assume thats saracsm. It's a very simple upgrade -- it was obvious what
the extra chipos should be, it was also obvious what most of the links
did. And I do have a 'factory' 1M board in my other Integral (although I
could have worked it out without that).
