C64 Help Needed

on Wednesday, September, 20, 2006 11:53 PM
I dug my Commodore 64 out of the garage and was eager to play some old C64 games -- gotta love the 5.25" disks! -- but I'm having some problems. Anyone here help?

I plug it into my TV using a cord that has an 8-pin round connector on one end, and 3 RCAs on the other end (video + audio R + audio L).

After powering on, the standard C64 screen appears, but it is black and white rather than the blues we all know and love. And none of the letters type the letters they are supposed, so I can't load any games. When I type, it's almost like the keyboard is stuck permanently in some altered state (like the commodore key is permanently pressed, or something -- but not really). Not sure how to explain. All's I know is I see "21" appear when I hit the "5" key. I'll see little alien symbols sometimes for other keys, etc. It's just messed up. I tried it last night and tonight.

Tonight it actually started with the blue colors when I turned it on; but within a minute or two, it had gone to black and white.

Sound familiar? Know a resolution? I'm about to unscrew this thing open I think. But hoping someone knows what is going on?

PS: Are there a couple hot keys you can press to cause it to automatically type in the standard, Load "*",8,1 or whatever to load a game? I thought that might be a way to at least see a game (wouldn't require me to type a bunch of letters on a keyboard that won't cooperate).

If you do feel ok about popping open your commodore, the area you may just want to look at is the keyboard. It should have it's own casing...

It sounds to me that one of the Commodore keys (there are two with the C64 symbole) has a contact that is always on (or pressed)...

The B&W issue could either be the RF connector or perhaps it could be related to the VIC chip... but I wouldn't know about fixing it... replacing it may help but I don't know where you can find one these days...

Ebay. You can get a single C64 for at least 40 bucks-ish.

But yeah, that could possibly be a vic-issue with the colors and probably a jammed keyboard.

Thanks for the tips! Gives me some things to focus on!! I'm not sure what a VIC chip is, but I'll find a schematics diagram of a C64 and compare it to mine to see if it's something I can just pop out and go to Radio Shack to get a new one. I seem to remember most things on the board being welded, though. We'll see...

Finding the VIC chip isn't really hard if you know what your looking for... but getting it out is the problem... Depending on the modle of the C64, you may have to use a soldering Iron (and if you don't have much experience with one, it could prove to be very very formable).

Back in the day, I had a few C64's that had major video/power/processor issues. Being a kid who didn't know much about the guts of electronics, I was lucky enough to have a friend who use to build stuff all the time and was a c64 fan too... I watched him fix my Commodores and he was really good at it. So, I know a little about it... but I'm no expert. Try using a new RF switch before looking into replacing the VIC chip just in case... And buying C64 parts (like a keyboard replacement) shouldn't be too hard... Here is a link...

VIC is really the video card chip... so you'd need another C64 to replace that. :P

But if anything, you might have to clean inside just in case. (But you did say that the blue returned briefly, so it might be just from not having been used for a very long time.)

Thanks again, Qix! Will look into. I have a soldering iron that I've been dyng to try! Although I don't have much experience with them. I've just watched someone use one before, so I think I could do it.

Unfortunately, you provide a link that doesn't work

Kia is right.... If you see any corrosion on the pins of any chips, or if it looks super dusty, it wouldn't hurt to clean it.

But there really shouldn't be any corrosion unless the system was powered a great many times (almost countless)...

Also, if any moisture found it's way in the system then you may have a rust issue.... In minor cases, you could try to lightly file the rust away (someone is going to call me a dumb ass for saying that but it does work) with a finger nail file.

I've had to work on old pinball and jukebox PCBs and its interesting how durable things use to be from that era.

I should have checked it out before posting it. It was an old link that use to sell Amiga and Commodore parts. But if I do find another site, I'll post it here...

Oh... and another thing Kia was saying is that it might be best to check out e-bay for another C64... because may most likely will be cheaper.....

.... but if you are like me, there is something emotional about the computer that you spent all those years an and you feel attached to it some how... I'm soooo like that....

Yep, all good recommendations. I did blast the insides with a dust blower can, and I think everything in there looked surprisingly good. No corrosion or anything, but I need to open the case and take a closer look... just to make sure. I pulled a couple connectors off and reconnected them, in case that would help anything, but it didn't. Yes, I'm surprised how good it looked inside; very durable, indeed! I might have one more C64 lying around -- each of my two older brothers had one, and I ended up with both, I'm pretty sure -- so if this one fails me, I'll have to keep my eyes peeled for the other one. Though, I have no idea where it is, so it won't be easy! And if all else fails.. yeah, eBay. But there is something nice about being able to play the one you grew up on.

There is a little toggle switch at the top, just to the right of the video connector. Anyone know what that is? There's no label on it. Is it like an old "Channel 3 or 4" toggle switch, like they had "back in the day"? It's right around where the RF module is. Maybe that's part of my problem. I'm using the RCA video inputs on my TV. So I'm viewing the C64 on the auxiliary video channel on my TV, rather than channel 3 or 4... ?

You'd probably need to try the toggle and see if it does anything. Channel three always worked the best for me. @_@order abortion pill http://unclejohnsprojects.com/template/default.aspx?morning-after-pill-price where to buy abortion pill

The switch on the back of the C64 should be the channle 3 and 4.... I don't think they were ever labeled...

I haven't hooked up any old systems to new TVs as of yet (i didn't think about that).... So yeah... If you can get it to work on both channels or an AUX channel, then it could just be the TV...

If you got an older one (like an old 80's/90's TV) then you might give it a shot. It may turn out to be the TV instead of the system...

Once you get your Commodore working, I'm interested if your disk drive status... If they still work, then you are very lucky.... I say this because the magnitic devices in the drive (and on the disk) may have suffered with age.... but there should be ways around it.... I'm still looking for some sites... I'll keep you updated...

I always remembered how popular the C64 was way back when and was kind of jelous to see others having it too. Since you could hook it up to any tv or monitor that had the RCA hook ups or the adapter to plug it into the coax cable.

Yeeeep.

Oh, if you still have that tv converter thing that usually comes with tvs... if not, hit up radioshack.

You can use it to attach it to the channel 3/4 switch box and you can hook it up to any of your new tvs. x_x

I'm not quite sure how to describe it but I don't know its name either, just that it's a convertor and you can plug it into the TV's cable input.

I think you hit the nail on the head on that one Kia for the tv game converter. Where you hook it up through the coax cable. Usually Radio shack will have them if not them then you will have to find those specialty stores that radio shack would get them at. I have seen like maybe a couple over here that I know of. But I think they are mostly gone by now for those kind of conenction. Traahb do you want me to take a look up here and find out for you. Just for sake of it when I get a chance to go down to one??

I feel your pain, Traahn.

I recently dug out my vintage C64 - I bought it in 1983. It was my FIRST home computer.

It was in storage and still covered with dust and dirt from BEFORE when I packed it away.

I spent about an hour carefully washing it and cleaning out all its many grooves.

I hooked it up, along with the disc drive. I used it as a prop in a video project, so it was not hooked up to the monitor, just together with the hardware - the computer and disc drive. Unfortunately, the disc drive constantly spun when I turned on the computer. With or without disc, it just spun endlessly.

After shooting the necessary video, I took my C64 (without disc drive) up to my computer room where I have my Atari VCS hooked up. I plugged it in, and powered it up. The red light came on... there was that 3 second pause of nothing while I waited for that beautiful C64 book-up text to display...

Then...

THEN...

The screen lit up with blue!

Dark blue inside, and the lighter blue border...

But...

There was no text displaying.

Just the blue screen and border.

I toggled power several times and tried the run stop restore combo, but I could not get the computer to boot up properly. No text, nothing.

There was a small rattle inside.

I eventually worked the rattle to the cart port in the back where a very small screw fell out.

Could this be the cause of the problem?

C64 still would not boot.

I have no idea what that teeny-tiny screw went to or if it was the problem.

I didn't have time to play with it, so I carefully packed away my beloved computer of yesteryear and placed it back on the storage shelf I pulled it from in the basement. Perhaps after being stored away for the last 11 or so years, in a not so protective cardboard box (no protection from the elements) has taken its toll. Perhaps some little connector inside was corroded or some tiny little component shaken loose during one of 4 moves the storage box went through in the last 11 years.

I've got a good C64 emulator, but there is nothing like enjoying the REAL deal.

Oh well, perhaps another day I can figure out what is wrong inside the little fella. Unfortunately, I believe the disc drive will not work either. At one point during filming, the disc drive just started up (spinning) all on its own - without the C64 being turned on. It stayed on until turned off. When powering it up, it started spinning again. I think age has had the best of it.

It was a good machine.

A flood of memories came back just cleaning off the machine that night. Such a cool computer it was, and could do so much with that little bit of 64K and a processor that was barely running at 1MHz. If only today's computer and software utilized their power as efficiently as the C64 did. Our applications and OS would be doing so much more than it does, and far more stable if that were the case.

Though dead, I was able to bring it back to life one last time - with the help of some movie magic, that is. Life is but an illusion anyway, so who says my C64 is truly dead when I can make it live again in the fictional reality I create with my video work.

A photo of my C64 "living" and loading again.

Ramble, ramble, ramble.

Good luck with your C64, Traahn. I hope you are able to correct its problems and make it live once again! where to buy abortion pill http://blog.bitimpulse.com/template/default.aspx?abortion-types buy abortion pill online

Seeing that picture almost brings me to tears.... I miss those days...

Ok... C64 emulation....
(unlike MAME or anything else, the SPA or other orgs are not enforcing any laws against C64 images.)

Emulator:

VICE: This is the emu I use. I think it's the best. Couldn't get their home page to work, but here is a link that you can down load the latest version.
http://www.emulator-zone.com/doc.php/computer/vice.html

Software/games:

c64hq
http://www.c64hq.com/
Lemon 64
http://www.lemon64.com/

Once again, there hasn't been any legal matters engaged by any type of law enforcment when it comes to C64 disk images. The sites I posted above have been around for years with out any threat of being shut down.

If someone has information that is contrary to the information I posted above, please let me know so that I or one of the moderators can remove the links.

Hope that you enjoy a great Commodore experience.

I usually press: Alt+D for full screen... and again to go back to window.

But if you want to play it in window mode, go to options/double size to get somewhat of a bigger screen.

Remember to save your current settings under Settings/Save current setting..... when you set stuff up the way you like it.
