Re: uSD card content?


 

Allison,

?

Ah yes, the "good" old days. :-)

?

My first disk system was a Heath H89 with a single H17 floppy. 40-track, hard-sectored, single-sided, single density, which stored 92k with CP/M. Operating with only one drive was tedious, but possible. Heath's clever BIOS created additional "phantom" disks (A: B: C: etc.) with one physical drive. So PIP B:=C:FILE.TXT would keep saying "put disk B in drive A and press Return" etc. as needed. Copying an entire disk was really slow. Lots of elbow exercise, but it worked!

?

Later, I had an S-100 box with a Micromation "Doubler" and two SS Shugart SA801 8" drives, which stored 488k per disk. Then a Micromation "Doubler" and SD Sales "Versafloppy" controllers which put over 1 Mb on 8" floppies.

?

Interestingly, my old 8" drives still all work, while most of my 5.25" drives are flakey, and the 3.5" drives are even worse.

?

On networking: I have Woolf Software's "Move-It" program, which connects CP/M (and DOS) systems via their serial or parallel ports. Each box can see the other's drives. So A: B: C: are your local drives, and RA: RB: RC: are your remote drives. There was a DOS version as well, but I've lost it. That was my networking solution for many years.
