What made you start coding?
-
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 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.
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)...

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.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.
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.

ooooh, i bet that getting that was like 3 christmas' worth of joy.

Mine was, quite literally, spread over 3 Christmases. I got my C64 (and tape drive) on Xmas 83 (84?)...I put up with the tape drive for a year. Then the next Xmas I got the floppy drive, and the one after that a printer. I never did get a "proper" monitor so everything was hooked up to a TV on channel 3. I'm sure that did nothing good for my eyesight. As for the thread's main question...I started coding because there wasn't much I could do with the computer other than play what few games I had the first year on cartridge. Since most games came on floppy, that wasn't an option for me so I started reading the programming manual, and saving stuff to cassette. The floppy drive was a godsend. After that I was old enough to get a job and spend my own money on my own toys, so I got a 64C (really the same thing, but in a gray/white package), and my folks sold the original 64 to a couple of friends of theirs who had a kid a few years younger than I was...then I got a 128...I honestly have *no clue* what happened to those computers and sometimes wished I still had them. Then I moved on to the PC world. Nostalgia got the better of me, and got a 64 Mini last year (thanks to Nintendo for starting that trend). Then the nostalgia only got worse :-) and a few months ago I purchased a 64C + floppy drive (the "real thing") off of Kijiji, a Canadian equivalent to eBay. I temporarily hooked it up to a TV via the antenna connector, just to confirm it works, but I don't have the room to leave it there permanently. I have the room (and monitor) to set up elsewhere, but need *some* sort of adapter to hook it up via VGA.

It's usually done that way, but it's the data bus that I must hook up to the PIC. I need something like a dual level bus transciever. Edit: I found this one[^], but I would need eight of them. The rest of the signals are inputs for the PIC and it's 5V tolerant. Edit 2: Here we go[^]

Coding was something my father could not understand, so he couldn't "take over", as it were. Plus the computer room in 7th grade was a great place to hide from the bullies.

Over 40 years later, you look at your own code and decide you could still do it better. It's a no-win situation. :-) (ok, it doesn't take 40 years to get to that stage...)

I remember watching the Project Gemini launches when I was little back in the early 60's. While I thought astronauts were cool, at age four I think I already knew I was too much of a clumsy nerd to ever be one. I was fascinated however by the consoles in mission control. All of those buttons, lights, and screens controlling this amazing machine. I wanted to know how all of that worked. 50+ years later I'm doing the UI's for our line of commercial inkjet printing systems[^]. It's not rocket science, but it's fun.

you need something that takes composite i believe?

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.
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.

Let me put it this way. We print fast enough (up to 17 feet of paper per second) that you could play DOOM at around 50 fps on the printed paper.

Our standard ink supply is a 208 liter barrel of each color: cyan, magenta, yellow and black. Some customers use bulk totes that hold close to 1000 liters. You're more likely to run out of paper. We can go through a 40,000 foot roll in less than an hour.

I have one of those, or at least a more sophisticated/expensive version of it that includes audio (this converter from Amazon would be video only, would it not?). Mine's either no longer working, or there's something wrong with the conversion somewhere along the way, because it wouldn't show anything. I'll admit I haven't fully investigated all my options yet...
