[cctalk] Re: Running DOS executables on other versions of DOSRe: Looking for Sharp PC-5000 disk drive (CE-510F or possibly MZ-80B)

I follow all that (on the DEBUG.COM notes) and appreciate the notes - that will save some time, I look forward to trying a few things out tomorrow. I forgot to do VER explicitly, but on boot up it is saying MS-DOS 2.00. And just now, I recalled that on github there is MS-DOS source (and bins) - I think Dave's Garage, he recently did a video on building and booting MS-DOS 4.0 from that source. Maybe I should use this as an excuse to try a 2.0 build? Or least, reading through the FORMAT.ASM, I see all the DOSVER checking stuff - helps confirm patch addresses, or maybe try just recompiling that one utility without this check. Reading through the CONFIG.txt in the MS-DOS 2.0 github repo, it's interesting near the end: (the use of forward slash instead of backslash, ha! and just above this, the comments mention /dev/<dev>) "A typical configuration file might look like this: BUFFERS = 10 FILES = 10 DEVICE = /bin/network.sys BREAK = ON SWITCHAR = - SHELL = a:/bin/command.com a:/bin -p"
