Anyone seen any good number plates on cars lately?

when I was at school friends (fit) mum who was recently divorced had SUE 1M on her BMW convertible

and a customer who use to come in had 1 BUY
 
One of my claims to fame is that I once had to write a program in binary.
I mean binary as in nothing running on the processor - system was in an idle state and binary commands/data entered through the front panel switches.
 
That sounds like you were a 'real programmer' then! Lol

Do you remember the 'real programmers don't eat quiche' jokes of the day?

Front panel switch programming doesn't sound like fun...one incorrect entry and lock up, no? At least I had a reset switch when I caused the thing to abend.
 
No, but the classic "there are 10 people who understand binary. I am one. Not sure who the other person is "

Q: what's the biggest problem with trying to create a Jimmy Carter (insert president name here) simulator in 8K of core on a PDP 11/44?

A: figuring out what to do with the other 4K
 
I opened the browser to see that pic and page number says '1111'...a binary looking page number.

That front panel looks archaic. I see the data/register entry buttons are split into nibble-sized sections.

Which year did you program that machine...1978?
 
You must have played 'Lunar Lander' at some point then :)

I recognize that teletype terminal...I had one clogging up my bedroom in the early 80s! It weighed a ton and almost killed me and a friend getting it up the stairs!

The spc-16 below was a 16 bit data machine - best of all it had 15 bit addressing (i.e. 32k!), the msb was used as an interrupt status (on the basis you would never need more than 32k of memory)

The machine on top was a SPC-12 - 12 bit octal.

These were from the mid to late seventies and I had to code in a bootstrap routine to boot from a non standard device with a hard coded (wired) i/o address.
Basically, I just plagiarised a standard bootstrap routine and put in the i/o address of the controller card I was talking to. It was the early eighties.

Magnetic core memory. You could turn the processor off, remove the memory board, put it in another machine and the program would carry on running from where it left off.

Happy days :)

KSR (keyboard send/receive)33.
They were REALLY heavy - analogue PSU and LOADS of mechanicals.
Surprisingly reliable considering their complexity.
