Oi. So after finally getting things going I started copying the Pro/380 OS files to a bunch of 1.2mb floppies. Great. However after a bit I started getting errors, and found that the disks were getting gouges in the tracks. Sure enough disassembly of my 1.2mb Teac showed that debris had becom

Don White designed the FPP8/A. From my recollection, the unit that was sold with 8/A was the second iteration of an Omnibus FPP8. I waa off in LCG working on Jupiter so I never got to see the original but I recall that the redesign to use the cycle stealing version that went to market was because

[cctalk] Better way to extract these TD0 images for P/OS.

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 know

QRST does run without issues on DOSBOX, the problem is it can't see the concept of the "A" drive which seems to be a mapped share as opposed to a "physical dopey DMA device". The floppy controller on PC's was always weird as hell, I do remember that. CZ On 2/25/2023 7:29 PM, Wayne S wrote: Si

[cctalk] Re: Getting QRST files onto a floppy (sigh)

Linux would be fine, however there doesn't seem to be a DOS emulator that emulates the ISA bus A: drive. I suppose Linux on a PC with that hardware might work, however the hardware in question is stuck at the "need to configure" which does require a DOS disk which can only be extracted by QRST

[cctalk] Re: Getting QRST files onto a floppy (sigh)

Win 10 comes with cmd so do you need to use dosbox? Windows 10 does not have a 16 bit subsystem anymore. Doesn't work. As for creating a DOS bootable disk, I think the problem is that the low level disk access QRST wants is not availible on a USB floppy drive. So you need a "real" floppy and
