RE: Help with a 8050 drive

Too bad - all of my 8050 diagnostics are made for the B series computers.

Try these things, let me know:

1.  You can try to format a disk in drive 0 or 1, see if either drive works.

header "disknamehere", d0, i01 (assuming you have a disk in drive 0 of an
8050 drive).
header "disknname", d1, i01 (for the left drive, drive 1)

NOTE: the parameter i01 above assigns the identification name/number; “01”
can be substituted for any two alpha characters.
-"diskname" can be anything, but keep it simple like "8050-0" so you know
in the future which drive this disk was formatted.

The command: ?ds$ will tell you if the processor board of the disk drive
is OK or not. The response you want will be something like: “73, cbm dos
v. 2.x…”

If your drive lights are blinking, use the user’s guide to diagnose the
blink pattern for hardware problems.

Carefully press tight and/or re-seat chips to strengthen IC connections to
board. If you have never done this before, wait to try this.
