Yeah, I got eventually.
As team lead, I was responsible for code releases. It amazed me how many null pointers existed in the code. Apparently I wasn't the only engineer who didn't understand pointers. For every malloc() there needs to be free().

Hi Jeff, thanks for reply. The switch is in the correct position.
The display just reads 000020 and blinking. No matter what front panel change is made, the display remains the same.
As i said i havnt delved into it yet, but will do later this evening.

Hello all,
?
My HP8563E is showing some peculiar behaviour. It sweeps OK to about 2.9GHz and then sporatically sees some frequencies. Below is an example of a 4-6GHz sweep.
Has anybody have got an idea what is going on here and where to direct my focus?
?

Nope, Borland Pascal, then Delphi.
It is possible to break the linker in Borland Pascal.

Sheesh. TECO. You are hurting my brain.
We had PDP-7s at the first engineering company at which I worked in '77. Advanced Electronics Development. We designed and built prototypes of various machines for various companies. It was a weird but apparently effective business model. I myself worked on a hematology analyzer. I remember being paid hourly until my first week claiming over 100 hours, after which I was "granted" a salaried position. Hah!
I remember using vi back then, but not EMACS, but I guess I can't swear that it was on the PDP-7s. We were using the original National PACE 16-bit ¦ÌPs and had a weird lash-up of file to cassette tape to "emulator" memory for debugging; turning off the emulator was a heinous crime, since recovery involved reloading from tape.
LOL - I DO recall playing the original version of Adventure on the PDP-7s.
Dang. That was back when engineering was fun.

Re: HP 141T Power Supply Help Needed
CONV mode is the only functional mode, i get blooming at almost any intensity / persistence setting in storage mode unless its so low its basically OFF.? ? ? ??
Beware of using the 141T in "Conv" mode, you cannot see if the intensity is set too high & causing damaging the storage mesh. You need to start with it in storage mode and turn intensity down to stop the blooming, then switch to "Conv", if there is any blooming, the intensity is set too high, do not increase the intensity once in "Conv" mode.

Attached are the numerous warnings in the 1973 manual and the label that is attached to the cover of my 141T.

The one William linked to on ebay is the right one.? The cables don't have that part number on them, so you have to? usually poke around for "(HP,Agilent) logic analyzer cable" or similar search term.? If you're patient, you can find them for less than that.

The 16801A only needs one cable, according to the spec sheet (34 channels).

You will also need pods (flying leads or other probe terminations) for it, of the 40-pin variety.

Though the "editor wars" are fun, I actually use both vi and emacs
regularly. I'm going to make a quick edit /etc/resolv.conf, I use vi.
If I'm sitting down for a ten-hour coding session, I use emacs.

'Twas a joke. But emacs has to be one of the most widely-ported pieces of
software in history.

If your boss is not paying for it... It's expensive.
2 to 3 years to complete, on average.
Say 50,000USD total cost, on average... and up... for many good US
schools.
Georgia Tech is... about the lowest cost... 10,000USD total cost.
Everyone is different... but IMO... the average person... depending
on which specialty they want... needs to have a strong background in
calculus... as in vector, complex, and differential equations...
linear algebra... numerical methods... statistics.
Computer science skills are required too.
Programming in Python or C
Simulations in software packages like Pspice
HDL like Verilog, or VHDL
Not to mention a strong background in
circuit analysis
devices
probably other stuff I forgot too.

Thank you Jeff! This thread has been fantastic.? Some of it went over my head, but all of you are valuable resources for someone like me trying to dive further into this field.? Getting into electronics and my current job was the first time I felt I truly found a passion.? Something I could make a career out of.? What excites me even more is that I am only at the tip of the iceberg.? There's so much more for me to learn, which is some ways is daunting, but at the same time energizes me.??
?
I know this forum is geared specifically towards HP gear, but considering that so many of you have such a wealth of experience and knowledge, is there another forum that would be more acceptable to ask similar questions about transitioning industries (to EE) and gaining more education/experience (also how to market yourself, resume building, etc).? Just more questions a novice like me might have?? I'm sure I'll have more questions as I move forward.
?
Thanks!

Its early history is a bit murky, but I was pretty sure it first existed on a PDP-10 as a set of macros for TECO. I remember DEC minicomputers (7s, 8s, 10s, 11s, VAX, RSX11M, RSTS/E, RT-11) with great affection. I used to moonlight in the early 1980s with another guy from FIT to setup DEC systems at night. It was great fun. At Dictaphone, we bought two PDP-1132s . Upon delivery, one of them fell headlong off of the delivery truck. Smash. Ever seen a grown software engineer cry? Those were good days. There was no PDP-11/32, you must mean /34 or /23. But yeah that sounds very sad indeed. We have multiple of all of the above except for a PDP-7, up and running with every OS that you remember, at LSSM. You should visit. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
