Which of you have programmed in obscure/old platforms?

>>57129649
I programmed old industrial PLCs.

There's no keyboard, you have to use a remote with some 20 buttons, no mistakes allowed or you have to start everything over again, and I typed programs with up to 8000 lines.

I'm guessing that DOS counts as old, right?
I started out programming assembly in DOS (I did this around 2010). The reason is that I was reading Mark Ludwig's Giant Black Book of Computer Viruses. Good times.
DOS is a nice platform, actually, for computing without having to deal with a shitload of complexity.

Does 8080 assembly count?

>>57129732
That sounds just awful.

>>57129649
I used to to code shit for old AS/400 machines. At the time, there was no documentation online whatsoever, so you had to use the IBM approved training materials to learn anything.

Those materials were old cassette tapes, and giant fucking binders without indexes. This was just 10 years ago too.

It wasn't too bad I guess; though the AS/400 language (RPG400) was pretty weird to work with. Never ended up getting to try RPGIV (it's apparently easier to follow).

But it is just 16-bit, isn't it?
It even can't handle necessary memory for average user today.

I programmed on FX-9000P computers when I was in 4th year of primary school. It was all in some Casio dialect of BASIC. I remember the teacher's computer was the only one that had a floppy disk drive. The other computers used some huge cartridges similar to the NES, but bigger. It was fun back then...

>>57129649
ATARI BASIC on my 800XL.
One of the slowest basics I believe.
Rendering a Mandelbrot figure took about 12-24 hours.
Using assembler sped things up by at least an order of magnitude.
Then my dad show me how much faster the VAX at his work was.
Still later there was fractint on pc of course.

I maintained something in DataFlex. After that, doing anything else feels like a vacation.

That's industrial automation for you.

My friend got some very old 16 bit HP machine at a flea. I tinkered with it for about 2 hours.
He is trying to find a floppy drive or floppy emulator for it.

>>57132237
I was going to add "but not by far for use as a desktop OS" but omitted it because I thought that was obvious.
What I meant there was that is is great for development that is close to the machine or that doesn't have to be bogged with all the libraries that we need to make something remotely useful these days.

6502 assembly code for embedded systems (maps, navigation, communication etc). Processor is from the mid 70's. They make 200 millions processors per year still.

>>57132947
I heard 6502 assembly is pretty clean

>>57132556
I think I have an old 5.25" floppy drive in a box somewhere.

>>57132983
>I heard 6502 assembly is pretty clean
Definitely.

The ISA is elegant and makes you craft elegant code. I have written assembly for a few processors over the years and indubitably 6502 is clean, tidy and elegant. It is the polar opposite of Intel and Zilog.

6809 (thus also 6309) has more features and registers but is a little less clean. Features demand complexity and a notable feature of 6502 (not indicated on Wikipedia) is that 6502 does not have (or need) prefix codes. 6809 has a few, so does Z80 etc. Later Intel processors have a veritable thicket of prefix codes.

Woz is generally accepted as a grandmaster of assembly programming, especially 6502. Two of his most elegant programs are available. Behold:

You just cannot get it more elegant than that.

To anons who have pics or examples of old codes/obscure languages, please post them!

I love seeing vintage things like this. Fuck, I wish I was born earlier.

Not much really, just some simple programs that drew lines on the screen, playing hangman, and I don't remember what else.

That's pretty fucking fascinating. Did learning this as a kid help you as an adult?

I didn't get into programming until a few years ago. I wish I knew what it was as a kid, but no one else in my family was into computers like I was.

>>57134043
>obscure languages
Other than assembly code (and in that case it is hard to outweird 1802) I'd say APL is number one weird.

1802 didn't do subroutine calls. Instead you changed what register was the instruction pointer. Think of it as pulling the rug out from under you - repeatedly.

APL brought with it a weird sub culture where it was a goal to solve whatever problem you had in one single short line of code. No mercy was shown to those trying to understand what was going on. Enjoy:

 join←{⍵⍪⍉↑↑{⍺,' ',⍵}/↓∘⍉¨⍺} 

>>57134291
Wow! Where the hell did you learn that, and what was it used for?

I legit have no idea what's going on in that line. Nothing like strangers on 4chan to make you feel like an idiot. Pretty neat though.

Took over really old ERP system from retiring colleague.

As for modern things - using recursive CTEs in SQL always felt weird. Even when you get better, you can't immediately see what they are doing.

I don't think it helped me too much. After 2 or 3 years of using those computers, my school changed them for 3 80286 PC clones where we programmed with Turbo Pascal. That did help me learn the basics of programming.

I was a Technical Librarian for a while at a university. We had a problem where the only copies of some old thesis was digital for an old ass word process for the Zenith 100. Had to write a program in basic to copy it over serial to a Linux box. That was a pain because I had to code the whole program on the zenith because there was no way for me to make a floppy that it could actually read.

>>57129649
Does APL and FORTH count?

>>57134317
Strictly speaking I only learned 2 things about APL: that it exists and that I want to stay well away from it,

That snippet is about making a Huffman compression tree.

>>57137518
Yes, both count though FORTH is more used by a wide margin.

>>57129649
In terms of obscure platforms, I created a virtual machine that only I know how to use and did a good bit of programming on that.

I'm working on an FPGA/hardware realization of it right now.
