PS - I didn't run into EMACS until I was transferred to STK in CO in 1991.

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.

When using EMACS, I always had to think about what keys on the keyboard I needed to press to do something. Probably beccause I was never a really good software engineer. I understood electrons, but not C pointers.

Re: Probe Cables for 16801A Logic Analyser
Yes, 16715-61601 is correct.? It's also listed in the 16800 Series Service Guide.
?
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.

Re: HP 141T Power Supply Help Needed
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.

Someone reworked the DG assembler (nova 1200 and later Eclipse) to assemble 6502 (modified instructions, LDA,yes ldax, yes, LDADY (load A indirect through Y register (addr + Y), and LDAXD which was load Adr indexed by X, then do indirect).? That kind of thing. Did wonders for homebuilt systems.? Program the EPROMS at work over lunch and take them home to debug. Harvey On 9/20/2024 11:39 AM, Dave_G0WBX via groups.io wrote:

Re: Introduction
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!

PDP-7s , actually.Was there an emacs implementation on the PDP-7? 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.

Re: Introduction
Crikey!
Mentions of Data General Nova computers! I was wrangling them (Nova 3's and 4's) back in the early 80's where they were used to run GCMS chemical analysis machines assembled where I worked. Memories of booting the 3's with the front panel switches, and some "fat finger" entered binary code via those console switches to "test" defective I/O boards on extenders, using a simple logic probe (two lights type!) And some software that played tunes on a Tektronix 4010 terminal! Thanks for the surprise burst of memories!
