Ok, so after pouting for awhile after destroying my only Teac 1.2mb 5.25 drive (old floppies are garbage) I sat for awhile and thought about this whole issue. The goal is simple: Install P/OS 3.2 on my Pro/380 but doing 21 floppies for the base OS, another 20 or so for the Toolkit, and God knows how many for the layered applications is, shall we say, for the birds. I feel like a spaceman trying to start a fire on the moon by banging rocks together. There needs to be a better way. So I looked around some more and finally found a program. Someone wrote it, called SAMDISK. From the "World of Sam" https://www.worldofsam.org/products/samdisk-utility Downloaded it to Windows10, fired it up (CMD mode only, thank God) and typed: samdisk 177-21.td0 disk0021.dsk And sure enough a 430,336 byte image popped up in my directory. Moved it to a USB, put it in my Gotek/Flashfloppy, fired up my pdp11/73 running RSX111M+, and did a mount DU1: /over It mounted. $ mount du1: /over $ dir du1:[*,*] Directory DU1:[ZZSYS] 26-FEB-2023 22:09 POSRES.TSK;1 42. C 23-JUN-1987 14:51 POS.SYS;1 441. C 23-JUN-1987 14:51 STARTUP.TSK;1 19. C 23-JUN-1987 14:52 SASCOM.TSK;1 4. C 23-JUN-1987 14:52 SAS.COM;1 1. 23-JUN-1987 14:52 SIR.TSK;1 74.

So we know that this tool can work to turn thse stupid TD0 files into images that we can use. Now to convert the rest of the files, and get a second Gotek. Because I am going to need to run two of them to emulate the two RX50's on a Pro/380. If I set one as drive 0, the second as drive 1, and use a straight 34 pin ribbon cable it might work..... Never dull. But this is a far less painful solution than screwing around with 100 floppy disks. CZ
