you are in basic with the following code:10 RUN”COM:98N1ENN”The TPDD2 sends a
small basic program over. That program does a quick poke command to determine
if a 200 or 100/102 is running and then calls for the appropriate loader code
to be sent. The end result is FLOPPY.CO on either type of machine. From: M100

Subject: Re: [M100] Utility disk image from sector access Oh now that is evil.
It silently/transparently delivers different data for the same filenames,
depending on if it's plugged in to a 100/102 vs a 200? EVIL On Sun, Aug 20,

I’m halfway there. I was able to create an image of the Utility Disk by reading
every sector with the Windows utility I’m working on. I deviated a bit from the
backup program that is on the disk. That program only copies the sectors that
have data. It does this by analyzing each sector. I went for a more brute force
approach and decided to copy every sector even if they are blank. I tried to
read the data in 256 byte packets but the drive didn’t seem to be happy with
it. I may try larger packets again but for now each sector is read 64 bytes at
a time just as the backup/floppy.co software uses. The image is interesting.
There are two basic program listings which are not tokenized. One for the 100
and the other for the 200. Then there is the actual code for floppy.co for the
100 and another for the 200. No I have to figure out how to write it back to a
blank disk……….. Kurt
