Sorry, to pester with irrelevant details, . . . 
"non-bootable disk"  Do you mean a Model 4 disk without system and/or with
errors?
OR, will it do it with a BLANK or PC disk?

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.
