Update on my Motorola EXORset 35 for sale – make reasonable offer (single transaction, non-partable… ie: take the whole enchilada)
re: VERY WELL kept vintage (working!) Motorola EXORset 35 to sell (ref OP: Feb 3, 2022)
As a retired EE and original owner, I have a working and VERY CLEAN Motorola "EXORset 35" (6809 based), complete with full original documentation and multiple System disks. Has lived in my electronics lab so has never been subjected to the elements or dusty environments, etc!
I would like to sell it so it might go/get into a working museum or collectors hands for the benefit of educational and historical technology.
As mentioned, it is a working platform (I was on it in December '21 and mid-2022), and both drives read & write. Overall the unit is in great condition (inside also!) - you'll not find another in better condition... and likely my ‘35 is the *only* functional ‘35 around anywhere – so please: appreciate it **IS** actually a rare item and gem.
NOTE: I was not able to post in a single thread (there is a verified issue with the Forum site relating to actual character counts)(anything other than black, straight, unmodified text takes up extra "room") so I will add a lot of info to my own post - *if* the system lets me tonight. Please look for my reply to my own post, labled: Motorola EXORset 35 in excellent condition-Continued
Background:
My EXORset 35 is an updated/upscaled version of the "30"... based on the 6809 processor. Production on the ‘35s were begun in 1982… and my drives are marked by QA as: 4-82. This unit had just a few hours as a show-demonstrator on it (in Motorola-proper in Phoenix-where I lived at the time) before I received it - somewhere around last quarter of ‘82. I fully believe I am the original owner and can share it has extremely low hours on it... far less than a literal work-year of 2080. A good estimate is around 800-900 hrs which implies around 3+ months of 40 hour work weeks. The majority of my work/what I did, was hardware design & PCB design so that "3+ months" is actually spread out over roughly 10 years. I was darn good {and fast} at writing code (one of the reasons I got to teach it). To save on machine wear and discs, I always paper-coded before I entered any files into my '35. Call me crazy, but that was me. Used some paper of course, but I had very few assembly errors - ever - due to that protocol.
Fun Facts: Among many interesting projects, I used this unit to create the software (to support my hardware) for the first intelligent seat ejection electronics for the USAF and USN, software for the 1st H2S sensor (also my design) and electronics - capable of <1% sensing [with sensor auto-purge], and software routines to compliment my hardware for one of the very first “smart” payphone products after Ma Bell deregulated in the mid 80’s.
The power supply fuse is marked 4A, which makes this a roughly 500W machine (max). The system was never stressed (except at QC time, like Motorola did with all their production units). I never personally inserted any aux or extender cards into the card slots (top rear left of the ’35). Also note: the serno tag on the back has dropped off somewhere along the line.
If you’re not aware of the original cost of a '35, it was definitely sticker shock even for me back then... over $17,000.00. So I share, this was not an inexpensive item in the "way back". The fact it is a very rare unit and working and has all the documentation and discs that came with it make it a darn good value, especially to a bona fide collector, but I'm not all about the $$$. I'm actually more interested in a good/proper new home for "Betsy" because she IS a working machine and in great condition.
Stats:
The ’35 alone, weighs: 57.5 lb.
The documentation and discs (ref: 2-3-22) weigh: 13 lbs.
The two newly (3-27-23) located ORIGINAL binders of ’35 info weigh: 13 lbs.
Notes:
The reason I'm selling this beauty at all is that I have to downsize my lab to what I tend to use most often.
BTW: To the benefit of all tech's and engineers: The filter caps appear to be in great shape (there are no leaks/bulges/dings/distortion/etc). [Since I hadn't run the ‘35 in a few years, I went through a slow scheduled & *methodical* electrolytic cap reconditioning/reforming cycle [over 2 days - a full 48 hour period] before applying full power to the ‘35 on the 3rd day to insure ALL the A.E. caps were indeed without issue. (FINDINGS: No issues.)
FYI
: I replaced the fan filter [foam], but it turns out I didn't really need to. The original was fine but a little weak, structurally. I'll send it with the unit so you can see how clean it was- I did not touch it/clean it. (ref the pic of the inside view of the '35 - you'll see how clean it was when I took the cover off)
FYI: The golden/brown vertically placed tape you see on the '35's video screen is something I put on many years ago. It's teflon tape [used during magnetics bobbin constructions that I once did] and was used as a field demarcation on the screen when looking at hex files. It just worked for me, so I left it in place.
NOTE to those unfamiliar with the Exorset:
Generally speaking, the LEFT drive is the USER drive, the RIGHT drive is the SYSTEM drive. (ref: pic)
Lastly:
If interested I invite you to reach out. The only thing cosmically required here is for one to be serious about being a/the new owner.
PS:
Don't know if anyone pays attention to or reads INTROs anymore, but I have one... It will give you an idea of this 'tronics wizard' named: nevadaOZman
Thanks for your time.
