Denial

I'm not sure what the details of this device are, but I've had my eye on it for a similar purpose to what you describe http://store.go4retro.com/ps-2-keyboard-encoder/ I love the old platforms for programming, but I've discovered that the good old days weren't really that good when it comes to 30 ye...

cool! now we just need a talking castle wolfenstein

I didn't have too many games for the VIC when I was a kid ... that darn money thing and those cheap parents, lol. I play Amok and Spiders of Mars because those are the games I had, but mostly its about revisiting some 30 year old programming projects. I'll admit I'm not using the actual hardware muc...

so how's the ill vic doing ? is he running again?

I always figured the reason older electronics lasted so long is because they hadn't figured out *how* to make the components cheap yet, both in quality and costs,... in other words, they didn't know they could put only .00001 thousandths of something in a transistor X and have it still work -- after...

I took my time before posting anything in this thread other than the comment about typing code with a jackhammer. ... That's because the VIC is, IMHO so much easier to program than the 64 and its a lot easier than the 64 to do impressive hardware hacks with. Ya, I'm currently finishing up some 'lef...

does the Pi have the required timing accuracy to do such a thing?
I thought the commodore disk drive timing was super picky, that and the Pi runs linux right?

sure would be a cool device. wonder if you could power the pi from the vic user port

You guys rock. Thanks TLovskog, That sounds like the secret I was trying to imagine. I knew they must be doing something clever! You guys are amazing, having disassembled the ROM back in the day. heh heh. Did any of the popular 6502 platforms from back in the day have an actual hardware single step ...

I was trying to imagine what you are describing, but it seems doing this for instructions that modify the program counter would be difficult. You couldn't put a BRK after a branch instruction, unless you rewrote that instruction to go somewhere you could control, same with JMP ?

I am real and love my vic20

I've been trying to figure out ( just curious ) how single step mode in HesMon for the vic 20 works. I know the 6502 has the ability to signal when it is fetching an instruction and I know you can halt the processor ... but doesn't there need to be external hardware onboard to allow such 'single ste...

Very nice use of the built in character graphics!

I have some code that I've just written for doing multi-voice sounds using a "track" that you specify. Although it's not hooked into any interrupt, it's designed to have a "service" routine called every so often. I was going to call the service routine from the VBI or similar. I'...

Well, I thought I'd chime in too, since I've taken the time to be on this board :) vic 20 was my first computer. I had aspirations of doing all this cool stuff when I was a kid, but lacked the financial resources or the "discipline" Today, as a "professional" programmer I find mu...

Wow, I finally found that side scroller I had such fond memories of as a kid. It was called "Spiders of Mars" ... always played it on black and white ... It was fun .. but not quite as smooth as I remember it, are the emulators really that off visually from the original vic ( I'm using vic...
