Sold!

Price drop and bump!

I have 5 Atari 5200 carts here that I am unable to test (no 5200 to test with). All look in great shape, no reason to think they don't work. Super Breakout Galaxian Centipede Pole Position Pac-Man Asking $10 including shipping to continental US for all 5. Payment via Amazon gift card preferred, but PayPal OK. Thanks!

Will do. Just a lot of projects going on right now so haven't had time to check it out in detail. Does look like U13 according to the screenshot. Is that a readily available chip for anywhere? Thanks

Welp, unfortunately the DK cartridge exhibits similar problems... So, if it's not the SmartWriter ROMs and the power supply seems OK according to my multimeter.... any other suggestions?

I realized how stupid and convoluted my last pic was, so I simplified and posted just a pic of the internal circuit board and the voltages on each wire. Hope it helps someone!

Thanks. I saw that, but didn't know how to match up the voltages listed in section 6.3 with the wires on the internal circuit board I listed above. I don't think my multimeter probes would fit inside the pin holes on the cable from the printer/power supply, and without a diagram I wasn't certain which pins were which anyway. So, I pulled that little circuit board and mapped out the traces so I knew which wire mapped to which pin. Based on a bit of logic, referencing the table in that technical manual, I came up with this diagram. Maybe it won't be of use to most, but perhaps it will help a newb like me who would like to check for proper voltage on those wires attached to that little circuit board. So, I believe my power supply is putting out voltage well within spec. My understanding is that there could still be other issues like quality of power that I wouldn't be able to see without an oscilloscope - but hopefully the power supply is all good. Can't wait to try with a cart! Will post back once I can test.

Thanks, I couldn't find an easy breakdown of the power connector and what voltages should be where, but I checked each wire location shown here wth my multimeter. With my black tip to ground and the system powered up I checked each pin and here's what I got: Green: basically nothing Green: basically nothing Red: 5.11v Orange: 11.95v Yellow: 11.93v Blue: -5.06v Brown: basically nothing Black: 5.10v

PM sent!

Thanks again for the info! Yes, I was looking at that cart - looks nice. More than I was hoping to spend, but perhaps worth it. What about the Adam side of things? Any solution there? I saw the thread about the SD drive for the Adam and it seemed so promising, but the guy making it seemed to just disappear - kind of sad for the community. Any options to run Adam software off modern media like SD card? Unfortunatley no retro stores in my area that I know off. I'm eyeballing a couple auctions on eBay, guess I could also check out a local flea market...

Nevermind, I dug deeper and found those chips in your pic. Many you really have to disassemble this thing! Like a jig-saw puzzle getting it back together. I popped, cleaned and re-seated each socketed chip and I get the same issue. A couple of the chips had these slim brown "pads" with 4 pins underneath each chip in the socket. Never seen that before. Now I need to find a cart or 2 to test with...

Thanks for the reply! Sorry, it's the standalone Adam unit - not the ColecoVision add-on. I forgot they even made that. I was hoping to ask for advice on and purchase one of those aftermarket multi-carts, but since I'm not sure how well this unit is working I'll look at getting some standalone carts and cassettes to test with first as you suggest. On that picture you attached, where is that board located? I got as far as taking the metal shield off the board inside the Memory Console and still no sockets. Is that beneath that board, or is it located in the printer? Thanks again...

Hi - Are these still available? Do you have any pics?

Finally got an Adam off Craigslist and was looking forward to getting some software for it! Unfortunately I powered it up and the screen looks corrupted. I took it a part hoping to find some socketed chips I could clean up and re-seat, but that doesn't appear to be the case. Has anyone seen anything like the attached screenshot? Any suggestions on troubleshooting what the issue might be? I have no software to try at the moment. Are there any general troubleshoot documents or common failures? Thanks in advance...

Thanks for the reply! Sounds like the price I paid. I could be wrong, and it was so long ago, but I do remember finding that discrepency in the manuals. I did a search and this entry on Wikipedia seems like it might confirm my memory: The Adam generates a surge of electromagnetic energy on startup, which can erase the contents of any removable media left in or near the drive.[2] Making this problem worse, some of the Coleco manuals instructed the user to put the tape in the drive before turning the computer on; presumably these were printed before the issue was known.[2]

Have been lurking in these forums recently and though I'd join and post a quick little intro. I'm 38 and have fond memories of my early computer years. My favorite of all time has to be the Commodore Amiga. I've lurked and hung out in some Amiga forums for a couple of years now, but actually obtained and fixed a few models just in the past couple months. I feel like that was the gateway to a hobby in retro computing for me. My first (well second) computer was a Coleco Adam. I actually got a Commodore 64 (no disk drive) first, but ended up returning it to the store (Zayre?) for a Coleco Adam when I found out I could get a computer with a tape drive, printer, etc. for nearly the same price as a bare Commodore 64! Typing in programs from magazine without anywhere to save them got old fast.. In hindsight, this must have been during a big Coleco price drop near the Adam's end of life. I kept my Adam for a while and did enjoy it before eventually getting another C64 - with disk drive this time. I remember arguing with my uncle (he had an Adam too) about the tapes. If I remember correctly, the Adam manual said to insert the tape THEN power the machine on while the instructions included with my games said to power the machine on THEN insert the tape and reset. After killing a couple of tapes by turning the system on with the tape inserted I learned my lesson. It was interesting to do a web search recently and read about this problem - the internet sure would have been useful back then for stuff like that! When I see eBay auctions for Adam tapes I have to wonder how many of them still work since they seem to have been so easy to kill. My favorite game of the time, besides the typical (I'm sure) Buck Rogers and Dragon's Lair, had to be Fortune Builder - I believe that was a cartridge-based game. It's sad to read threads about things like the SD drive where the maker of a cool device seems to just drop off the face of the earth, leaving a lot of previously excited potential buyers in the dark. I do have to say I admire the community - I can't believe new games and hardware are developed for the Coleco/Adam, and the user base seems to be relatively at peace. Nothing like what's left of the Amiga user base which is full of constant bickering. Anyway, not sure if I will ever own another Adam - not sure I have room for the huge beast, and not sure how rare they are, but I'll definitely be checking out an emulator. I'd definitely consider a Coleco Vision if I could find one at a reasonable price. Thanks for reading, Mike
