What is your C64?

[NOD32 user]

My first experience with computers was an 8080 and then an 8085 that my father was working on in the late 1970's. They came as project boards to be hand-spooled with about a 20 key keypad to be hand programmed directly in machine code. Then, a video game system kit built possibly before they were available in stores in the early 1980's. After that I was fortunate enough to have my on Tandy MC-10 with 4kb then later 64kb of memory, and a CoCo 3 that I much enjoyed. In between I also had a TRS-80 Model III computer with programs to conquer like ARS and Eliza[^], both of I took an interest in even at the tender age of 12. The most important thing, apart from having all of the manuals for BASIC, was the monthly subscription to hardware specific magazines to practice typing and learn programming techniques by examining other people's code. On the 68B09E I even learnt to program directly in machine code, used the cursor interrupt to operate a print spooler, and picked up all of that from one book (possible the one by. David W Harding) having already learned every conceivable command in BASIC. LOGO at school on the Apple IIc computers was quite straight forward. I solved Island and with the assistance of an Atlas from the school library found that it is Haiti. By the time I was second-year apprentice I was teaching the other students ladder logic for Idec Izumi PLC's - shifting into IT ten years after commencing a trade was the most straight forward thing, and a real understatement at that. Now I recommend an early involvement with children and technology. If someone still has all of the Australian MC-10 and CoCo magazine, acquire a free licence and put them up on cafe press to be printed on demand. It does not matter that it is the same editions over and over, just buy one copy a month. I had interests in sport and captained an u15's Australian Rules team, played basketball and was never stuck inside apart from for several hours a week in front of a keyboard WITH NO INTERNET. Later I became proficient in HTML, and then PHP. Currently I am completing a Masters in Cyber Security. The course work is easy, it is just a matter of writing enough to please the assessing facilitat

Hi, My first computer was a Sharp computer with tape-drive, it was a cp/m machine. I quickly sold it to buy an IBM compatible PC. I was able to change the 8086 CPU (running at an incredible 4.77MHz) for a super fast Nec V20 CPU running at 8MHz. As a student I spend almost al the money I earned working in the weekends and holidays on this machine. I bought an EGA monitor with 16 colors!! (Yes 16, not 16 million) before that I had an amber colored display (It was so much more interesting to call it amber than orange). Than I bought my first (second hand) harddisk of an incredible 5Mb. It was the size of a shoe box and when you turned it on you could hear it slowly coming up to speed. It than made all kinds of clicking sounds before it would become idle. I think this process took about 30 seconds and I always had the feeling it would drain so much power that my mum would come up because the lights downstairs would dim. Of course this wasn't the case, but this harddrive made you feel as if it did. I bought it second hand for a couple of hundred US$ but when it was purchased new about 5 years earlier the first owner must have paid at least a couple of thousand dollars, they were very expansive in the beginning. The disk drive was 360Kb (and that was double sided). These disks would cost about 3 to 5 US$ a piece. And me and my friends would play Frogger or King's Quest. I also purchased an additional 8087 co-processor for super fast math and a special memory board to upgrade the memory to an astonashing 1Mb (640KB for MS-DOS than some 128Kb got lost and an additional 256Kb as a really super fast memory drive). Well I still had a lot of fun on with this machine and so did my friends. At my school, with some 600 students, I was the only one with a PC. Most kids had no computer and if they had a computer it would be a Commodore 64, Atari or Sinclair Spectrum. I really liked MS-DOS and my keyboard was so much larger than that of a Sinclair Spectrum.... I learned BASIC and let the computer draw by calculations some nice looking pictures on the screen (in two colors so either black or white). The EGA card had a resolution of 640 x 350 and before all these dots were calculated it took my computer about 10 minutes!!! Later on I started selling computers and started my own computer store and after that I started programming. So at the end I guess it was worth it. Kind regards, Clemens Linders

Another Atari 800, and Star Raiders player. Started with the cassette drive, and eventually got the 5-1/4" floppy. And different languages including LISP. Remember the magazines with code listings in each issue? Type them in, DEBUG THEM, and play the games. Then modify them. There was a small Atari club nearby, and we'd drive up to the huge club meetings in Detroit occasionally.

C64 One favorite trick was to map a Sprite (hardware based graphic entity 24 pixels wide by 21 pixels tall in 63 bytes of memory) to the low addresses of memory. It was like an x-ray of the OS working memory. You could see the system clock binary counter running, pieces of memory involved in making the input cursor blink, the system call stack, etc. Very cool. If you messed something up, turn it off and back on within a second or two to start over. My father wrote his own family budget system on that platform. He used a fixed record length dataset on the floppy drive for his storage.

After school with a Digital PDP8, with 4K of RAM. Woo! Big day when we upgraded to 8K and DEC Tape. ASR33 teletype terminal, paper tape for boot loading and for storing short programs.

My first was a C16 (the first model which looked like the C64), with which I spent my time playing games with my brother (at the time they sold "legit" pirated games compilations in the stores), and when I was alone, trying to learn programming, which I found so fascinating. When I finally got into the best part of it (POKE'n'PEEKs), it broke and we were never able to repair it because it went out of production since too much time. So my next dream was the Amiga, so much that I actually spent all my (very little) money on a magazine which teached Assembly, which I started learning without having the computer. When I finally got the Amiga, in 1995 (it was the first batch produced by the new owners, ESCOM, after Commodore went bankrupt), I didn't have an assembler, so I used my time to learn the OS and what it had already: AmigaDOS (that is so good that it can be considered a programming language, there's even a racing game made in ASCII available on Aminet) and ARexx (an amazing feature that still today is nowhere to be seen in any other OS, at least in a similar form). I then learned other languages as soon as I could get my hands on their compilers (yes, Assembly too at a certain point, finally...). What was so great is really what you already described, probably, the way you could "touch" the hardware and "speak" to it directly, to make something that it was not made for, for example, or just to get that extra performance/feature that the language didn't have (in the case of using a C compiler on the Amiga, for example, you could add some ASM to access HW directly in a part of your time-critical routines to do things actually easier, and much faster, than you would by doing it with C itself). It was the absence of this forceful abstraction that is, legitimately, present today in every system (even in consoles), which really meant freedom, and on the Amiga, it was done without giving up multi-tasking (though you had to disable it momentarily if you went too deep in the HW, but it was made for that). It was a time of discovery for all our young minds, and to master the machine. I believe today's kids might have a similar inner experience but in the end, it's always the machine which masters the man, which forces the way, while at that time, you were the one which chose the way. It was also something relatively new and not so common, which added to the mystery, while today it's quite a normal thing to have at least one computer in the house (smartphones included). It's taken for granted, and because

My first 'puter was a Sinclair ZX81, with its standard 1Kb RAM. Less than a month later I had the 16Kb RAM expansion which BTW, was so heavy it was almost impossible to keep the Sinclair balanced. For me, it was the best thing ever invented after the TV set.

[Paul Kemner]

The impact of the magazine code listings was huge. While you were typing them in, you weren't necessarily paying attention to how the program was written. Then when it didn't run you had to fix things. Then you often played with it to make the program easier/more difficult. From the very first, you were learning how to debug and modify someone else's code! That translated directly into a job skill, and I'm not sure if anything offered today does that.

My first was an Ohio Scientific C1P with 4K Ram & Microsoft Basic. It was a great computer to learn programming on before I graduated to the Commodore 64.

I still have my C-64, purchased in 1985. That is what started me in a career as a developer. On my desk right now, is a coffee mug with the C-64 schematic printed on it, in tribute. I had some amazing stuff for that old PC, like a CAD program that worked with a light pen, and a voice recognition device that could display the notes of a tune as you whistled into a microphone. I had a lot of 'cracked' software on 5 1/4" floppy disks. I had a special hole punch that would turn a single sided floppy into a double sided floppy. I also still own my old C-128 and my SX-64 luggable.

never had a computer growing up, even thought they were getting quite common, my parents believed and still do that computers are a passing fad. so whenever I could, I was over at a friends house learning his C64 making text adventure games and such, at school there was the Apple IIe's in all the labs that had the Basic ROM, sometimes a few friends and my self would build little games on these and leave them running for the next class to find, or until the power got cycled :laugh: In high school, I fell in love with the 286 lab, they were quick and responsive. for the intro to programming class we needed to turn in a minimum of a one printed page program, mine was closer to 50 with menus, graphics, and small games to play. good times. I came across that floppy a couple years back, took awhile to find a machine with a working floppy drive, but sadly it had sections that were unreadable. oh well.

My first computer was an Osborne I computer. CP/M OS, dBase, and other apps came with it. 5" monochrome screen, and dual 5-1/4" single sided floppies.

[Alexey Biriukov]

Yamaha MSX2. Although I didn't own it, that's the one I spent countless hours after school in grades 8 and 9, doing everything from ROM Basic to opcodes. It had crazy number of colors (dont remember exactly how many but no less than 256), hardware sprites (fun!), 4 channel sound synthesizer (so much fun!), and Zilog Z80 inside (not that much fun at that age but still). And of course those beautiful Konami games I still occasionally enjoy in an emulator.

I don't know what was my C 64. I took one look at the specs and determined to never play with one! CQ de W5ALT

A C64 from 1984. Last year I dug it out of storage along with a 1541 drive. Couldn't find the power supply. It hadn't been used since about 1991. I built a power supply from scratch along with a custom power cable, recapped all electrolytics and tested the 2 voltage regulators out of circuit (and they were bad) - wound up replacing those. After all that, it did not work... at first ... black screen. I was able to troubleshoot it and determined that the PLA was bad. I replaced the PLA (found a pulled chip on fleaBay) and it fired up and worked fine including video, audio, logic. I then restored the 1541 drive (which still had a disk in while in storage all those years) and it too worked including that disk I just mentioned. I had a supply of old 5.25 disks but most did not work but I was able to get about 15% of them to load! I bought a joystick for it and I played some old retro games. Pretty cool to use the old computer that got me started when I was a kid in the 80s.

My first 'c64' was a home built s100 bus system using a z80 processor with 4K of RAM. There was no programming language, just a monitor program that fit into a 2K ROM (was named Zapple). With the monitor program I could peek/poke memory, dump memory, execute from a specified location and insert break points. I built this system during my last year of college (electrical engineering, 1978). I basically learned the z80 instruction set by the numbers. Over the years, the system grew until it had 64K or RAM, dual 8 in floppy drives (dual density!!) and ran the CP/M OS. I kept the system until I could buy an Amiga. Those were fun days, learning to program with the z80 machine code, designing/building boards for the system (serial port board, votrax based speech board and a driver board for a selectric printer mechanizm).

"Goodness" fell more in an eye of the beholder scenario. Compatibility between platforms wasn't a mandate so every competitors offering had their own engineering go wild at times. The Commodore line was really good at graphics and sound. Lots of games took advantage of that. Tandy CoCos were not good on graphics and sound as the Commodire but flew circles around many others with its BASIC... add an RTOS (Microware's OS9) and the CoCo blew everybody else on the computing prowess department no contest. Apple was... well, Apple! The Woz in all effect pre-Mac days :cool: Atari was also very good on graphics, somewhat good on sound. A you-can't-lose way to go on the 8 bits machines line. The Atari ST upped the stakes later on but by then everybody was on IBM mode. Texas Instuments TI 99/4A its an oddity but an interesting one, half way in graphics and sound capabilities, not too good on its BASIC and expansion capabilities. Of all these I have a few, still work on them, repair, retrofit and soup up where possible. It's a fun way to deflate from the day to day modern hardware and software woes. I started late on the Commodore, my start was with Tandy's TRS-80 line and the Color Computer series. My latest addition is a replica I assembled of the Jupiter Ace.

Atari 400 was my first, too. First program I wrote in BASIC, I ran out of memory. Upgraded to Atari 800 with 48K. I still have that one. Back in the day I would buy old game cartridges and unsolder the ROM and replace it with an EPROM and then burn games from magazines like A.N.A.L.O.G. to the EPROM. The EPROM burner plugged into the joystick ports of the Atari. My first foray into assembly language programming was with the Atari.
