Tek 576
FYI The seller quoted me $200 for shipping (freight) to Florida. I'm already working on a project 576 so I passed but I was sorely tempted. I was also concerned that "Freight" shipping would mean that

Yet another 2465B repair effort.
I got three of the Tek 2710s with some surplus years ago. They power up and react to the buttons but I couldn't get a display on any of them. I sold one but the other two are gathering dust around her

'Tektronix Short Destroyer'
6:34 PM. The listing has already been taken down. No record of it so that means E-bay took it down for fraud or something similar.

Obsolete Motorola IC
I checked my 1980 and 1985 IC Masters and my 1969 Motorola Data Book and that part isn't listed in any of them. Do you know what year it was made?

Tektronix 834 communications tester... what for?
"They used the case for quite a few instruments." I have an 8080 CPU tester built by Tektronix that uses the same case. IIRC the 834 can be used by itself as an RS-232 terminal but if you want to use

Scope grounding and generators

Tektronix 834 communications tester... what for?
I really should pick up something like this since I have computer systems (intel MDS-800, SWTPC, etc) that use an RS-232 terminal but all of the 834s that I find locally are missing that T-cable. Than

Tektronix 834 communications tester... what for?
I don't know what's in them but the 834s that I saw years ago all had pods on them. Does anyone have a manual for an 834 and does it show a schematic of the pod or cable?

refurbishing TM500 and TM5000 hardware
Regarding any electronic equipment that hasn't been used in a while, I bring it up slowly using a variac and I've noticed that the odds of it working has improved from about 50% to about 90%. But also

Carry-on adventures (was: Re: [TekScopes] Tek R453 - a rack version of a portable scope!)
I was in Kansas City about 25 years ago and found a rare Apple II prototype. I made the mistake of trying to hand carry it back on an airline the next day. I literally spent about 4 hours in the head

Tek 3A1 Module
My rule of thumb when looking at electronic equipment on E-bay or anywhere else is to look *closely* for signs that anyone has been into it. If it isn't *sealed* and it's not guaranteed to work then e
