Hey Mike,

Thanks! I will try them out either late tonight or tomorrow.

Since you're currently up to speed on the Altair disks, can I talk you into writing a simple exerciser for me? I need a program that lets me do the following 3 things:

1) restore to track 0  (Command: R)
2) step to track N (Command: S <t>)
3) load/unload the head (Command: H {1/0})

a nice 4th feature would allow me to step between 2 specified tracks when I hit the space bar (Q to quit).
(Command: S <t1> <t2>)

Probably need a command to select the drive too (Command: D {0-15})

Simple program... :-) I need this to align the Altair disk where I replaced the head last night.
