On the negative side, a small regression error has
crept in and 4k
BASIC
will no longer run. This is not so bad because if you
could run 8k BASIC
there's no reason to run 4k BASIC.
This is broken. Since 4kbasic and 8kbasic ran on the same altairs it
suggests something in the emulator is broken.
FYI: much of MITS and Altair compatable software used input Port 0FFh
as a 8bit input (usually to configure IO).
