Did you mean BCD, or was this computer designed by Timothy Leary?

No I mean our old currency: £sd - pounds, shillings - of which there were 20 in a pound, and pence - of which there were 12 in a shilling.
So £2/13/11 + £5/8/4 = £8/2/3.

I know what UK currency was like before decimalisation, but I've never seen it called LSD. Thanks for clearing that up for me.

What prompted this post, was realizing how incredibly easy Software Development is now days. I was being incredible lazy: changing a few lines of code; testing; and then back round to do the next few lines. Which I suspect is the norm these days.
Imagine having to write an entire program, (in COBOL or Assembly language), by hand. And, if it compiled, the next step was to put it into production! If it didn't work our options were either put a, machine code, patch into memory and rerun or splice the mod into the paper tape, recompile and run. How scary is that?

Dude, I thought I was old.
When I came into the digital world from analog instrumentation there were already Rk05 2.5mb disk pack style drives and the glorious vi editor in play.
That must have just sucked to see the next morning coming.

Not really, no - we saw it as a natural progression, and tools to make life easier.
Mostly because we all knew the old way worked-but-was-sh*t and the new way almost-worked-but-was-way-easier.
Except vi: nobody could ever remember how to get out of that.

I started with paper tape via a teletype machine on an acoustic coupler to a remote IBM way off in the big city (Manchester). Later I worked with Pr1me computers at the polytechnic - they had greenscreens, advanced technology. I still remember getting 50+ error messages from one missing full stop - none of which mentioned the aforesaid full stop. Eventually got a real job working on ICL equipment (2960s I think) but back to punch cards. We also wrote the code (FORTRAN IV) on coding sheets which were processed by "punch girls" to create overnight compilation runs, debugging involved changing out one or more cards, occasionally punched personally (when the unions weren't being awkward) and eventually straight into production - no, test system. Lots of finger crossing! A year or so later we got green screens but the head of the department hated them and tried to make us stick to punch cards for another year until they took the machines away. He also hated Fortran-77 on the VAX machines we used for the real-time system. He couldn't cope with names longer than six characters in mixed case!
I won't mention the compulsory flowchart requirements... oops, just did.
Aah, the good ol' days!

Quote: I won't mention the compulsory flowchart requirements... oops, just did.
I go back to the 60's. I remember a human factors course I took in the mid 70's. The professor said they had done an experiment to test flow charters versus non flow charters. Seems the flow charters got their program running with fewer compiles but the non flow charters made friends with the mainframe operators and got more runs. Time came out about the same.
I still have my plastic template around here somewhere. Same drawer with my slide rule
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

I found that the surest way to get more runs was to occasionally show up in the machine room with 12 dozen homemade, still warm chocolate chip cookies (one advantage of living fairly close to work). I could've gotten away with murder for at least a couple of weeks after that.

When I started, the first project I was on used a Honeywell 200, a Four Phase mini, a Perkin-Elmer (later Interdata) 8/32 and an IBM 370/158, with languages including Assembler (3 different flavors), Cobol, Fortran, PL/I and RPG, plus MVS JCL. Somewhere around here I still have the textbooks and manuals for the IBM side of things; the others have all thankfully vanished into the mists of time.

By 'eck lad, you 'ad it easy! When I started we had to punch the 'oles into leather straps with our teeth, then walk 500 miles to feed it by 'and through t'reader, and output was by electric shock!
No but seriously, hand-punched cards (eventually we got one of these[^]) using a hand-held thingy. It was a chunk of metal with 12 square holes in it, and a square "poker" thing you used to push individual chads out, having looked up the hole pattern for the character you wanted. Then you sent the card deck off by post (from the Post Office) to the University, and a couple of weeks later you got your punching errors back. You re-punched, sent it off, and if you were lucky got your compilation errors back. Eventually you got "Hello World" or the equivalent, and jumped for joy!  That was at school...
But yes, once graduated and working in London, initially we wrote out Cobol coding sheets by hand, sent them down to the girls in the punchroom (you were supposed to leave them in the tray outside, but going in was too much temptation for some). The next day you'd take your cards down to the ops room; we had both ICL1904 machines with George III (and a teletype interface too!) or the faster IBM 360 machine. Remember "the well" on the ICL machines - effectively a queue of waiting jobs, but a prioritised one where, as a junior programmer doing testing, your jobs were being constantly overtaken by production work. Some jobs, those needing significant resources (like more than 32kwords), might sit in the well for days... then oh! the Joy of a VDU screen with TSO!

As kids, we used to draw on these manilla coloured cards with little rectangles missing. Always different to each other and seemingly nonsense patterns.
Years later, found out they all belonged to a single program which had been scattered when Mum tripped over crossing the road at Uni one day.
I still miss the HP calculator Dad used to borrow from work sometimes that took little sticks with magnetic tape on em for storing programs. (Perhaps a HP29C) Playing that moon-lander simulation was teh best!

Ok, so this subject has probably been done to death in the past but things are always moving on... New job means new laptop, new boss says tell me what you need and we'll get it for you - I'm in R&D working on test software generally, a lot of number crunching maths, data processing and apps for embedded applications. Graphics are typically light. Do I go for something off the shelf or spec me up something special?
