What made you start coding?

COSMAC :-)
Quote:
The RCA-CDP1802 is a byte-oriented central process-ing unit (CPU) employing the COSMAC architecture and utilizing complementary-symmetry MOS technology (CMOS).
RCA was a pioneer in early CMOS devices and sent quite a bit of it into space because of it's lower power consumption. Early on they even called CMOS COSMOS, which of course was a similar acronym.

It's my project for the winter and I want to replace lots of discrete logic with microcontrollers. AT least the tiny OS already works.
I have lived with several Zen masters - all of them were cats. His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.
Well when I heard of it I was thinking a microcontroller could get rid of the discrete logic (and the joys of static/dynamic hazards due to propagation delay) but wasn't too sure if you wanted to go that route...

We all know that pet-projects are not to finish, but to learn and enjoy...
"The only place where Success comes before Work is in the dictionary." Vidal Sassoon, 1928 - 2012
I have many, many pet projects that I started with great enthusiasm and curiosity, "can I make this work?". Many of them petered out once I got the "yes, I can make this work" stage as I lost any determination just to polish it to the end point. I wrote many games for my friends to play but if there was no interest from one or more of my friends then the project would fade away.

these days I'm sure you can. What with all the hobbyist kits out there now. best of luck with this project. i've been considering building a custom ECU for certain types of diesel engines - the kind used in schoolbusses and other medium industrial vehicles making them more suitable as boondocking vehicles, but i didn't have the property i needed to be able to work on one until maybe now. We'll see. It's a hail mary of an idea, but it's kind of cool if anything comes of it.

Schoolbus? How boring :-) The Elf's CDP1802 was the first processor to fly into space. It was even believed that it was aboard the Viking and Voyager probes, but that's probably not true. That would be great when Voyager Six returns.

i was 8 when reagan was in office. I liked to read while eating breakfast. If not for that I may have never picked up that Applesoft BASIC manual that shipped with our craptastic Apple ][gs By the next year i was wiring stuff into the joystick port on the motherboard. 10 years later i was at microsoft.

My family got a TI/99-4a around '83 I think. I learned how to write BASIC programs to solve my HS algebra/geometry/trig homework problems. A few years later, I was at UNI as a CS major until I found a job that paid well, but interfered with lab hours so I quit school. 10 years later, I went back to school and finished. I got my first coding job before I graduated and I'm still here 20 years later! :)

When I was about 10, my father gave an AP course in FORTRAN for high-school students at the local University. He took me along a couple of times, and I was hooked. This was about the year 6 BT (Before Terminals). God only knows how many punched cards I ruined before I got a program that would compile. :-O

You're not young, 40 is like ancient :laugh: And with 31 (almost 32) I'm not that young myself anymore :sigh: WoW came out when I was still in high school. I'd say I'm a little too young to have played Warcraft: Orcs & Humans, but I have played Age of Empires which was released only two years later :laugh: I've played Warcraft III though.

Was gainfully employed as a chemist and was exploring a new Inductively Coupled Argon Plasma Spectrometer we had just bought. Could not find any analysis tools for the PDP-11 running the dang thing, so I learned PDP-11 assembly and wrote my own. Then did the same for a Gas Chromatograph we were using for oilfield gas analysis.
A human being should be able to change a diaper, plan an invasion, butcher a hog, navigate a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.

what a way to get started. into the fire as it were. I almost bought a crusty old PDP-11 but i didn't know where i'd keep it. These days, i could probably emulate one on a phone. :laugh:

The biggest problem at the moment is to find a PIC32 that still runs at 5V. I could run the CDP1802 at 3.6V, but then I would have to lower its clock frequency. I have had an underclocked 1802 for 40 years, now I want to overclock[^] it. I intend a smaller PIC to conrol the 1802's clock frequency and operating mode. It also must communicate with a small serial ROM and copy it's contents into memory after a reset. This way I can keep the ROM out of the Elf's memory map and still have something to boot from. With a PIC in control of the clock frequency, I can do almost everything, from single stepping instructions to full blast or overclocking.

I sucked rocks as an elementary school teacher. Was married and needed a new career. Luckily, programming and I were a good fit.

Yep. Bear in mind that the argon plasma was created by passing argon gas through a coil of water cooled copper tubing energized by a 5KW RF generator. Never set anything on fire, but the generator frequency was very close to the middle of the CB Radio bands. If we ever forgot to close the faraday cage, we blew up every CB radio in town.

I got to do some C programming in my first calculus class in college and found out that I enjoyed it. I picked up more programming skills on my own then decided to take some programming classes. Fun times :-D
Just because the code works, it doesn't mean that it is good code.

Failed my last year of University* because I had been playing World of Warcraft too much. I still lived at home and my parents weren't pleased. They just sold their IT company to an uncle, an employee and a third that wasn't with the company until he bought it. My mom said "you're going to find a job or I'll do it for you, you can start there!" And I said "but I don't even know how to write code!" And then she gently whispered "THEN YOU'LL FUCKING LEARN! :mad::mad::mad:" And so I was hired because I was the son of old management and the nephew of new management and also because I had some affinity with computers, being a gamer and all. No one in this story regretted that decision. I liked programming and I learned it very quickly. I learned a lot, wrote some great software, introduced some new technology to the company, made them a lot of money (earned some myself as well), and then I moved on after four years :D Another five or so years later and here I am :D *I still finished that last year of University, earning me the title Master of Arts :D

I was fortunate enough to convince my parents to get me a ZX Spectrum as a Christmas present in 84, when I was 13. In those days, you could buy magazines that contained BASIC print outs for games. I learnt to debug before learnt to program. You'd type in a program, run it and get some weird result - and have to try to figure out where I'd miskeyed something. I started being able to see how the bug could manifest itself given the code I'd entered - something I believe I'm better at than most programmers. From there it was a matter of modifying the programs, and mashing bits of them together into new ones.

Silly I know, but what about a potenial divider 5V to 3.6V, Vo = Vi *((R2)/(R1+R2)), Vo = 5*(3.3K /(3.3K+ 1.7)), Vo = 3.3v, I always go for slightly below max. There are some good level shifting IC's (Texas Instruments)...

Ah, 'twas the year 1983, and I decided to find out what all the hoo-rah was about. I had seen a classmate's BASIC code a few year's earlier and the idea that a few arcane incantations could actually tell a machine to do something interesting was totally baffling. But, once I was introduced to it and tried it, I found that I could do it like nobody's business. (BASIC-Plus on a PDP-11 running RSTS-E) Money for nothing, and the chicks for free.
