@Michael: I can't even remember whom I knew with the KSR-33...

Growing old is a real pain, isn't it? :-)

You're bringing back memories of a tape punching experience. I can't even remember whom I knew with the KSR-33, but I needed to punch tapes to get some bipolar ROMs burned! Hard to believe that that was the only method they accepted!!

Anyway, IIRC, I threw together a current loop interface to my Poly 88, and away we went. Pretty sure I still have the tapes, as well as tapes for some early microcomputer programs, like Microchess ferinstance :-)

@Michael: Couldn't afford a paper tape reader, eh...?

The sad thing is that I'm sure there were occasions when I could have picked up an old paper tape reader ... but I didn;t because I fuguresd "they's be around for ever" :-)

 

My dream is to pick up an old teletype terminal with fan-fold computer paper and both a punched card reader/eriter and a papertape reader/writer.

We had to enter the first-level boot-up sequence using front panel switches.

@betajet:Lots of testimonals in the back, including one from an iceman who had worked 12-15 hours a day until he took the ICS Interior Wiring Course and was able to earn US$2.50 a day working just 8 hours.

There is so much to be learned from these old books -- often they provide a unique window into the past.

I also have a load of full-sized hardback books from the 40s, 50s, and 60s describing how to build logic circuits out of vacuum tubes, relays, and even magnetic logic.

FYI, the magnetic logic used the same magnetic cores you find in the old magnetic core stores, but using them to implement logic functions like AND and OR ... and, of corse, since they were cores, each logic gate also acts as a non-volatile memory element...

## The veterans in our department refuse to dump those obsolete manuals!

God bless them!!!

It's easy to throw stuff out now, and then realize whet we've lost in years to come...

## You clearly missed out on the PDP-11 era, and you have my condolences.

My first job out of university in 1980 was working on a team designing CPUs for mainframe computers.

Two managest left to form their own startup company and invited me to join them, so my next job circa 1981 was in a small six-person company using a PDP 11/21.


The hard disk drive cabinet was the size of a washing machine. The drive itself comprised a numbrer of platters that (in a glass case looking like a wedding cake wjen removed from the system) that offered only 1MB of storage. We all shared one folder -- files used the 8.3 naming standard (no spaces or special characters). We used the first character of the file name to indicate who owned which files ('M' for "Max"

We had to enter the first-level boot-up sequence using front panel switches.

Ah, the good old days :-)

I'll go with 1889

Hey Max,

Google found me a picture of the 1889 edition that looks the same, though yours is in better condition.  So you have 20 years advantage over my 1908 "Electrical Engineer's Pocketbook" (International Corresponence Schools, Scranton, PA) which belonged to my grandfather.  However, I bet my book is a lot more useful.  For example, it has tables of copper wire resistance (B&S Gauge 0000 is 18,290 feet per Ohm at 50C and weighs 3381.4 pounds per mile), detailed diagrams of electrical wiring (knob and tube, of course), lots of diagrams of dynamo-electric machines (motors and generators) and alternators, and a chapter on "car wiring" -- for streetcars.  Way too early for vacuum tubes, but plenty on batteries and electric lamps.  (At the time, mercury-vapor tubes had to be tilted by pulling on a chain to establish initial conduction, and then released to form the arc.)  There's even a section of first aid, showing how to do artificial respiration by moving the victim's arms.

Lots of testimonals in the back, including one from an iceman who had worked 12-15 hours a day until he took the ICS Interior Wiring Course and was able to earn US$2.50 a day working just 8 hours.
