Oh so true.
As mentioned any "open" drive like floppies and older carts the end points
of the travel is more suspect than the bulk of the length.

Going from IDE to MFM/RLL is trivial. scrounge up a 100x ATA bus
controller and hang it on. Same idea as the article using the xt 8bit
1002.
The original plan was to figure out the protocal the parallel port
SQ270 (internally ide) disk uses.

I remember someone asking here about VLB ethernet cards (long time ago)...

Of which ancient systems was this true?
Today's CD-ROMs are the opposite, I've heard: as the head positions
to the outermost area of the disc, it tends to push dust along the
guides, and many CD drives accumulate a pile of dust out there,
preventing it from reaching "the end."

Got it set. I got impatient and used GSETUP31 to initially set the
scrambled date, time and drive types to get it to boot and found the
setup program from Mem-Tel on the hard drive (duh). I copied it off for
future use so if anyone needs it just ask.

I'd want to be the one pulling the catapult release. ;)
But, before I did that one it would be a TI99/4a... nice cpu hobbled by a
really bad design.
Allison
The only problem with the TI99/4a would be that it isn't that heavy.
Something like a TRS-80 or something with a CRT would be a little bit more
eventful. Not only do you get the fun, you get the fireworks, too :-)

Does anyone out there know of some sort of gizmo that could be made that
would convert an old RLL or MFM Hard drive to be used with a parallel
interface? I've seen then for IDE, but that's it. I've got a couple of
old HD's laying around that I'd like to put to use, but there's no room in
any of my computers to put them.
By the way, does anyone have any old Apple or TRS-80 external disk drives
that they'd want to get rid of for a few bucks? I don't need the drive
itself. I need the case …
[View More]and power supply and that's it. If they're
TRS-80, I could use the drive itself, too.
I'm also looking for disk-based (and tape-based) software for the TRS-80
Model III. I'm especially looking for the TRS-DOS operating system for it
(floppy got ran over by an office chair *cringe*).
