And I almost bid on the 2 CEC p770's until I looked at the power
consumption the way I had them configured. 768 GB RAM and I think 24 cores,
I would have had to add a new circuit to the room.

Hello,
I have had this issue with a number of H/Z89s I have. The terminal board
and the logic board are two separate systems, so it seems to be common for
the logic board to go down while the terminal board keeps working. I would
check voltages on the logic board, then take it out of look for blow

Any Zenith Z-90 owners out there (which appears to be the same thing as a
Z-89 / Heath H89, but with a DD soft-sectored disk controller)?
I was given one up a couple of days ago which isn't giving the expected
"H:" prompt at power-on - but it *does* give a blinking cursor, and hitting

Actually, since they buy 'in bulk' from carriers, they are surprisingly
reasonable; their quote to ship an H960 rack from Arizona to me was less

Just a reminded to everyone; most PakMail franchises are prepared to go
somewhere off-site, pick items up where they sit, and then pack them; I've
used this service several times for 'pick up only' items.

One thing I started was putting together a home setup. But like all the

The 'stack' consists of 2 each IBM p720's, a CR6 HMC, and a KVM drawer.
