If the format is at all standard, the contents will simply be extracted. You can then create your own DSK image as you see fit, based on those extracted files without worrying about the PDRIVE. I believe that Phil Ereaut's "Emulator File Display" program will also display the characteristics of a DSK/DMK image. In this case, it advised: "35 Track S/Density S/Sided Sec/Cyl. = 10 (10 * 1)" I admit this information is only useful to someone familiar with PDRIVE, but it does provide enough information to someone who is. I thought there was a program out there which actually spat out the PDRIVE codes for a given disk but it has slipped my mind at the moment.

I couldn't figure out any PDRIVE settings that could read it either, but I never used NEWDOS/80 very often. To make things simpler, I changed the download to contain two single-density disks formatted by TRSDOS 2.3. These should be readable by any Model I or Model III operating system except TRSDOS 1.3 (which could easily convert them). By the way, here are the PDRIVE settings I used to read these new disks: TI=A,TD=A,TC=35,SPT=10,TSR=3,GPL=2,DDSL=17,DDGA=2 The disk was a single-sided double-density disk formatted by Model III LDOS.

I can seemingly read the directory in SU32 using N3D, but no luck in NEWDOS/80. Are you able to help?
