PDT-11? - test-drb@ccmp.vtda.org

19 Dec 1999

What is a PDT-11? I just got one new in the box with 7,000+ pounds of other
brand new (1965-1978) dec stuff.

It has two TU-60s and looks like a VT100.

As I am damn near dead and *very* sick... and my family and I had to load
the stuff ourselves(last 2 days)... I am not able to list contents yet but
.. "TU-56 units a-plenty". I will post pictures soon. I guess I don't have
to say a Christmas tree this year is simply out of the question now.....

[will be back online in a day or so when we get the trucks unloaded]

 Tony writes about the innards of 10-base-2 Ethernet
transceivers:
  The power supply comes from an isolated DC-DC
 converter in the transceiver case which takes in 12V from the computer
 and gives out -9V for the transceiver chip. 
I'm not sure about separate transceivers, but the ones integrated on
NIC cards for PCs often used a little non-potted four-pin DC-DC converter
module made by TDK.  At a guess, it's about 20 mm by 10 mm.  I've
successfully

 kludged them onto boards that were designed for the
potted module style.

Anyhow, I have a lifetime supply of NOS of these TDK converters, so I could
sell some cheap or trade them for other small stuff.
