The "media type" hole on a 1.4M?
There exist some drives that ignore the "media type" hole, pqrticularly
many/most? of the ones that IBM used in the PS/2s. They rely on the disk
controller board to tell them when to go to reduced current.
or the index hole on a 5.25"?
The type hole on a 1.4M disk.
Did 1.4 support the DSK option of STAT? It gives some
more info about the
format.
If so, try
B:
A:STAT DSK:
No, but I did find a program:
TARBELL MINI-FLOPPY DIAGNOSTIC OF 8-1-80
STANDARD VERSION 1.8
40 TRACKS 18 SECTORS
\Most PC floppy controllers will not handle FM/Single
density. Use Dave's
test program on your PC to see if you have a chance.
What I would really like to do is find some way of connecting a 3.5" disk
drive to the MITS hard sectored controller card set. This would give me
the 300 or so K and allow me to run MITS basic off of the disk. Do you
know anything about how to do that? Is it possible? Maybe with a PLD to
deal with soft/hard sectored stuff?
I have not investigated anything yet so I am not sure what it would
take. If its possible I'm sure I could get it done.
