RE: Transfer 8050 disks - Catweasel (was: PET 2001 Fix)

Ah, just the man!

Bill, IIRC Herb got some of his Micropolis manuals from you; I 
wonder if by any chance you have any PDFs yourself?

The drives in my VG systems need a little TLC but for some 
reason the manuals I have are corrupted somehow, and I'm 
hoping to avoid paying Herb his fee...

TIA, 
mike

Here is a good resource on the 100 TPI drives.

> After my "small" fire problem of last november, I took as a priority to take images of all my floppy disks. The disk formats that I have to backup are 1541 (1 or both sides), 1571, 1581, 8050, Amiga 3.5 and 5.25, few atari, apple ][ and also PC. As I haven't got any more my Commodore material operationnal until I'll make a global clean, I had no other solution than acquire a catweasel board.

In my case, I've tryed 4 or 5 different drives that I had under the hand and choosed the oldest, a Toshiba that came probably from my first PC-XT; it supports 80 tracks, it's direct driven, and accepts flippy disks without any modification.

> My only issue [with exception of dirt disks] regards 8050 format. I had previoussely to the fire no 8050 working correctly (none was able to format known to be good floppy disks [DD/96TPI certified, working perfectly on 1541/1571/PCs but old]). I thought that catweasel was able to read 8050 disks, but, reading deeply the manual, I've seen that I had to find a "very hard to find" 100TPI drive to connect in the PC !
>
> As googleing, I've found that 100TPI drives were only built during a small period of time by no more than 3 or 4 builders. Drives with 96 TPI and 100 TPI seems to use nearly ldentical mechanics (except for WORM or DRUM that converts rotative movement from stepper to linear movement for head). They were driven by the same electronic board (that we don't have in our 8050). The idea would be to find a drive in 96TPI that would be a "familly cousin" to what's inside the 8050.
