I had forgotten just how much fun the TRS-80's could be.
At least for the moment I am giving up on trying to get
a TEAC 55GFR to work and just grabbed a par of disks from
one of my COCOs to work with. I think one of the things
I need to do is try to move all of my old 5.25" disks to
3.5" disks as I expect functional 5.25" drives and disks
are just going to become rarer. Maybe I should try the
GreaseWeazle on them and see if it can image them.
You can image them with Dave Dunfield's 765 utilities; GreaseWeazel
hardware isn't necessary.
Image them with what hardware? A PC or one of my TRS-80's?
Trakcess, by Roxton Baker, is a BASIC program for TRS80 (including 3/4)
that provides sector and track viewing and editing. Trivial mods are
needed to it for double sided. Looking at the code of it is an
extremely easy way to learn how to to controller level actions on the
3/4, if you don't already know.
I will look for that. I used to have some nice DiskZap programs
but have been unable to find any of them. At least not on a disk
I can still access. :-(
On another note, at one point my 4P failed to read from
a floppy. The "Cass?" prompt showed up followed by the
"Memory" prompt. I'm confused. I thought the 4P didn't
have any ROM in it. Where could these prompts and an
apparently functioning BASIC come from?
If I remember correctly (unrefreshed dynamic wet-ware), IFF you
responded to those two prompts, THEN you got the BASIC, with the
[cassette BASIC] version number. Did you actually GET BASIC after you
responded to them??
I didn't try typing in a program but I got the "READY" prompt.
I thought you had to have MODELA/III and be able to load it to
get to BASIC on a 4P. I would be very surprised that while it
could not boot TRSDOS it could somehow load MODELA/III from the
floppy.
