Re: TDS3000B USB floppy emulator
On-topic: My own experience with 720K 3.5 inch disks is entirely with atoggle quoted messageShow quoted text
Toshiba T1000 laptop computer (running DOS 2.x) that I think I purchased
around 1988. The T1000 had/has a single 720K 3.5 inch drive, and while
it worked fine (read/write/format) with any 3.5 inch disk labeled as
"DD" (720K), it was totally unusable with any floppy labeled as "HD"
(1.44M). It would not even format an brand-new unformatted HD floppy as
a 720K disk, which surprised me. I still have the T1000 (stored away
somewhere in a box), along with a bunch of DD 720K 3.5 inch disks. When
I last used the T1000 (early 1990's) the DD (720K) disks had become
pretty much unobtanium; I kept all the 720K disks that I had when I
subsequently "retired" the T1000 because I figured the T1000 would be
unusable without them. I seem to also remember that reading or writing
any 720K disk on other computer(s) with a HD (1.44M) disk drive was
"iffy" at best.
Off-topic: if anyone has managed to retrofit a T1000 with a HD drive and
is willing to share the info with me as to how it went, please contact
me directly (_not_ thru the Tekscopes user group) to share the info, at
