Not pestering. I appreciate you taking the time to answer my questions.
"non-bootable disk" Do
you mean a Model 4 disk without system and/or with
errors?
Yes, or a Model III disk. Or a disk I know has bad sectors on it.
OR, will it do it with a BLANK or PC disk?
Didn't try either of those. Not sure I even have any.
This might help troubleshoot
I don't know that troubleshoot is the word to use. It's not trouble.
It's just curious as I didn't even think it was possible.
not "troubleshoot", so much as understanding a feature and/or confirming
what is "known"
If it will do it with a blank disk, then the statements that it "doesn't
have ROMs" are more faulty. It obviously has SOME ROMs, to start up
enough to try to boot. But, this would tend towards disproving the
statements that it doesn't have BASIC in ROM.
And, if it has the "POKE" command, then all sorts of wondrous things
become more easily available.
Good point. I'm going to have to go look at the 4P Tech Ref Manual
again. Maybe I am wrong it has Model III ROMS that can be switched out
for 64K Ram mode. But then, what is the purpose of MODELA/III.
