There's a few IBM 3164 terminals down at Purdue University Salvage and
Surplus that are about to be thrown out. If anyone wants one, let me
know, and I'll ship them for $5 + packing stuff + shipping. Respond soon,
they'll probably be gone in a day or two.

Hi
I see the rest seem to have a similar opinion of
this manufactures drives. I got mine from experience.

Hi
This can vary, from not working at all to the occational
bad read or bad write of a sector. Some times it shows
up as a data dependent problem. The disk formats fine
but can't write all 1's or all 0's.
In both of my cases, it would occationally damaged data
on a write that would show up as a non-recoverable CRC error.
Although it is recommended that the termination be on the
last drive on the cable. I've never found it an issue
when the two end drives cable connectors are only 2 to 3 inches
apart. I have been known to put the termination, where ever
it is handy, while trouble shooting( such as swapping drive ).
I also alway tape the terminator to the drive that I remove
it from. I don't know if I or someone in the future will need
that terminator. If it is right there, I know it is the right
one.

Eh? How are they SCSI? I had one of these once, the drive in it was most
definetly a Hitachi ESDI disk... They're such cool looking machines, too...

Would you and Fred please define "flaky?" What symptoms are exhibited by
an improperly terminated drive?

Not at all. I've salvaged ST225s before by board-swapping, with good
results.

It bypasses the write-protect switch; when in the "on" position,
write-protect is enabled.

Hi
One should note that double termination can also cause flaky
operation as well. I've seen it twice now that I have a machine
that has a flaky disk and I open it up and see a terminator
on both drives. Removing one brings back normal operation.
One of the machines was a KayPro and the other was my Olivetti
M20. I suspect that these were that way from the beginning since
both normally ship as dual drive machines.

Honestly, I would've expected you Brits to say "nicked", but yeah.. FYI
further synonyms (american) would be jacked, ganked, swiped, etc.
