Hi all --
Against my better judgement I picked up a TRS-80 Model 16 last week.
Initially it wasn't working at all, after replacing the Z80 CPU and CTC
chips and doing a pretty thorough cleaning of the drives it seems to be
happy.
It came with a 15 meg disk system which isn't faring so well
Hmmm. Sounds like I should get the original drives from the VCF warehouse at
Infoage.
Thanks Chuck.

I spent a bit of time on this yesterday. I have four QT242s (all were NOS but
two had broken plastic disk guides). It turns out that the only drive that
works is one of the ones with broken plastic. So, I did a little swapping,
connected it to my PC/AT and I now have MS-DOS 6.22 on an 8” floppy.
It seems that you are right, I start successfully the Memorex 102 with
the PSU without flickering, this HDD uses the same voltages as the
Mitsubishi M2894-63D 8" disk drive (24VDC - 5VDC).
It remains me to find out which components are faulty
http://www.zeltrax.com/classiccmp_forum/uts40/M2894
Note that this produces the same result with either of the two disk
drive connected however your suggestion is interesting.
These two drives have the same age and some capacitors may become faulty
simultaneously. I will analyze the hypothesis, thanks!

If it were me, I'd just do a new layout using parts you can still buy today.
OK. There haven't been that many replies. The other route is to try to
reverse engineer the boards.
Does anyone have any of the boards below (except A607 and M701 that Vince
Slyngstad had a very nice effort to reverse engineer already)?
A high res photo or scan would be nice!
Thanks!
