a32a2f36be Advances to correctly reading bytes. 
Something is still amiss though. Maybe I'm supposed to update the checksum?

906b6ccdb7 This appears to be sufficient for the Electron to _read_ SCSI. 
So that's step one.

a2a928e262 Takes a guess at the format of IIgs .po files; wires them through to the actual machine.

 2020-11-12 18:01:26 -05:00

5287c57ee0 Adds the IIgs as a user-selectable machine. 
Albeit that there is no underlying machine yet.

8da7806ee9 Liberalises segment parser not necessarily to require a standard epilogue. 
It seems that real disks don't always have them; I guess the boot ROM doesn't require one.
