I think Boisy and I have freed up even more than that under level 1 or
2 with the drivewire stuff we're working on, with the (perhaps quite
significant) limitation that it requires leaving out any console
drivers for the CoCo. If you can handle the Term device being on a
telnet connection, you can get a huge amount of free space in the
system map. I haven't tried running Level II BBS in this
configuration yet (we just sorted out this "headless" mode earlier
today). Before I was running out of system ram with only 2 lines
running, hope we might get 3 or 4 now though.
We could actually free even more but there is a bug that only shows up
with very small bootfiles. If that gets sorted out I think its
another 12k (I *think* we gained about 20k already, but don't hold me
Assuming this mode does allow me to actually get processes using up
512k (I have little use for a ram disk personally) then I might try to
get my hands on a 2MB board :)
