I have one of these drives, but no disk for it. I was able to do the PC
hack to make it work, but I'd rather have the disk. Is there anyone in
Canada that could make one for me for a small fee?
I made up a bunch of TPDD1 and TPDD2 disks from NOS disks, designed and
laserprinted nice labels on good glossy stock, and they are for sale on
arcadeshopper.com
(I don't run that shop, I just sent him the stuff to distribute that way
so they are discoverable, and so that he can deal with 100 different
mailings and I only have to deal with one.)
I DID pay it forward several times over, the fact that someone sent me a
disk for free, and made several copies for free for people for a while
before making one big batch and dumping them on Greg to deal with via
his store. (and then a couple times saw that disk appear on ebay
immediately after spending time and one of my few nos 720K disks sending
it to someone for free incuding mail...)
I do feel a little self-conscious or defensive saying something is for
sale that should just be a favor, but it's only a favor a few times,
after that it's a time-consuming chore, and I don't want to have a 2nd
job as an ebay seller. So I just slogged through 20 of each in one big
job, and sent them all to arcadeshopper in one shipment, charged him
enough to cover the disks, labels, bags, shipping, and now it's someone
else's actual compensated job to deal with mailing the individual ones
out any time someone needs one.
There is no way to hurry the process of making a disk with the included
backup utility, especially if you test-boot each one, and it puts wear
on the drive. Especially the TPDD1 disks are a pain because the TPDD1
bootstrap procedure is a pain.
The same goes for the DVI disks for 100, DVI disks for 200, the TPDD
cables, and the DVI cables.
Plus I thought, being a store, it would have a better chance of turning
up in google searches when a new person got a TPDD on ebay or smething,
and they go to search for info about it, they would have a better chance
of finding out that the lost special disk or cable is available, vs a
post or two here where only a few people who happen to be on the list at
that time ever see it. I don't know how true that's turning out to be,
but it's got to be better than nothing.

Ohhh Ahhhh,
Stephen, are you hinting that with an actual drive I could recreate my
own TPPD 1 disk? That would be cool. I am just about to do a belt
replacement on one who's belt turned into black goo - When I removed
the belt it literally went everywhere - and then the cleanup of the
workshop bench was spectacular. Alcohol worked a treat :-)
While there are beautiful solid state versions of the TPPD now, but
the concept of a drive that clicks and whirs is very appealing to
me, Just like the 8" drives in my PDP11.
Kindest regards,
Doug Jackson

I believe that it is just not possible to use PC hardware ...
drive, controller... to read a TPDD disk.
The disk is encoded with FM whereas a normal drive is MFM. Or
maybe that is backwards.
Not sure but possibly a Catweasel drive can be used. But that is
specialized.
Perhaps though a real TPDD drive connected to the pc is good
enough? I think there is software for that .

Is there really no way to read the 3.5" disks in a PC (even an
older one, via DOS, with a discrete FDC IC)? I'd like to
backup my TPDD disks, but my M100 is set up for the DVI right
now, and I'd prefer to not redo all of that.
