Author Topic: C64 Memory Chip Locations? (Read 7564 times)

I need to take the memory out of one of the c64's that dont work since the other one I have works but it doesnt see the memory in it. tired googling it.

Carbon Dudeoxide · « **Reply #1 on:** February 05, 2009, 01:53:59 AM »

C64? Commodore 64?

I don't know much about it at all, but it looks old. What do you plan to do when you locate the memory chip?

squall_01 · « **Reply #2 on:** February 05, 2009, 10:33:46 AM »

move it to one that is working, the one that works doesnt see the memory so I suppose its bad.

squall_01 · « **Reply #3 on:** February 06, 2009, 08:41:54 AM »

never mind thanks to an manual which I never really read them unless I have too, I was able to locate them. There soder on too the board so that means that I have to soder an such. The only thing is that I thought that the machine I wanted working had chip creeping so I took out some chips I thought were the ram but it was like for the video an such. It wouldnt display an found that one of them was in the wrong way. So I dont know cause you cant really get these anymore but I want another one that I can use with out moveing it. Any easy way to test them without removeing them like an oscilator or something.

This pretty much sums up your history here...

This is really funny!

what ever, yeah it cause of does patio, why would you want to read about something if you cant use it an understand features that you may not use.
The chips look the same. It's not like theres a video card or anything.

Except the video chip is a 6566 and the DRAMs are standard parts... oh I forgot you can't read...

DRAM chips are still available from parts distributors for less than $2 each. I wouldn't try to extract chips from a board for transplantation. They were soldered by a wave soldering machine, and the heat from an ordinary soldering iron (used twice - once for removal and again for implantation) will most likely destroy them.

I would smack you if it werent for that insight. I can obveisly read i posted about 1,000 post, any way yes. well I thought it was all hand soldered. Something like that seems to advanced for them to have had. Well thanks for telling me that at least someone on here is still familar with these. Can you still get them in that size or would they be bigger? I suppose it depends then doesnt were I get them all together.

Carbon Dudeoxide · « **Reply #10 on:** February 06, 2009, 10:02:24 AM »

First, you have over 3000 posts.
Second, how do you know the two chips are compatible? Do they have the same amperage? Voltage? Do they fit in the right place?
Things that are soldered on are not meant to be removed.

Dias de verano · « **Reply #11 on:** February 06, 2009, 10:03:03 AM »

I don't know very much about C64s except what I found on the web. There were a number of different types of C64 and they used different RAM chips.

True I suppose i should take that into consideration when I noticed that some of the cables didnt fit. ummm that will be hard to determine maybe i should let this go or take it to the shop some time an see if they can do it. I am not as weak as I seem. I dont have a belt but studied several mma an a good bit of my freinds have belts. Aside from the aterial that I have in my room.

BC_Programmer · « **Reply #14 on:** February 06, 2009, 10:09:45 AM »

breaking from the conversation for just a tidbit- but doesn't the C64 use the same processor as the NES? a Motorola 6502?

Also: I cannot add anything on-topic because I haven't a god-*censored* clue what squall is saying. Something about getting belted by his friends. sounds kinky.

squall_01 · « **Reply #15 on:** February 06, 2009, 10:12:11 AM »

No, I have no clue learing about the machine as I go. No my friends have a belt in a type of martial art.

I think he invited me to his room to see his "material"... Do you think I should go?

Thats probably a far trip for you but I watch out for the rouge squrriels an stuff. Squrriel chuck power

Dias de verano · « **Reply #18 on:** February 06, 2009, 10:22:23 AM »

Basically, squall, the proper way to do something like you are attempting is:

1. Find out all you can about the subject. You have internet access, is it too hard to type "Commodore 64 hardware" into Google?

2. Make sure you know what you are doing! Read some basic electronics text books. Learn how things work.

3. Be confident and knowledgable to start the task

4. Perform the operation.

The trouble is, you skipped steps (1) to (3).

Already the second page.....

Squall, I doubt any store will touch anything that old anymore.

BC_Programmer · « **Reply #21 on:** February 07, 2009, 08:59:06 AM »

There are forums specially dedicated to the C64 and troubleshooting... guess what will find those...

A google search.

Or, more likely, on each of three days they thought "I'd better do my homework", typed "paskal" into Ask Jeeves or AOL, found nothing, and carried on surfing for bikini babes or playing games or whatever young people do with computers, and panicked when assignment day drew nigh.

You've just illustrated the most likely scenario...

the best people to talk to is someone who's had experince a page could only led you so far till you run into all. Thanks for letting me know that this stuff still really thivse. Like you said no one really does this stuff anymore. Second that part is true but I'm not of the depot type.

theres some thruth to that.

The wall of incomprehension?

squall_01 · « **Reply #32 on:** February 08, 2009, 02:18:22 PM »

thats what I'm tring to get around but not this way more so in programming then electronics.
