Wow, guys! I've learnt at least something of what has been posted here. 1. Don't sell anything that has a sentimental value. 2. Tell clearly to your parents/mom/wife that everything you have is valuable (something like "no, mon, isn't trash") 3. Don't trash anything before putting a message here in Atariage 4. Buy any offer even for platforms you don't know. 5. If you're going to sell check everything for rarity before (at least to get a scan for Atarimania!) In fact sometimes I regret selling my first 15 Atari cartridges, the lot included a Raft Rider cartridge that was in very good state and Crystal Castles that I liked a lot.

I'm very worried, if I had an E.T. cartridge it would drop of value from 0.50 to 0.49 USD by the new availability of cartridges

Thanks a lot, kevtris! I suppose I can leave as it is, I think this modification is a lot better that cutting pin 4 of lockout chip. I can live with the off LED.

Recently I've got a NES for $1 USD without power supply but with the two controls, I've cleaned it and managed to get it working. Apparently it was discarded because the dirt in connector prevented cartridges to work and furthermore the cartridge port was wrongly put together so it didn't accepted cartridges. Only one control works and I've been able to put right the cartridge port. The point is that I've discovered that the power light doesn't work, I've followed the LED traces through the PCB upto the mainboard (NES-PCB-11 from 1987) and I've found a kind of modification that I couldn't discover in Internet. So before undoing any connections, I would like to know if someone knows what is this modification. Note the yellow cable, the resistor and a soldered jumper in the big connector that I'm supposing brings LED voltage to zero so it doesn't turn on.

I use a spreadsheet and when my collection is "stable" I print the sheets as a little catalog. Also I keep rarity, state of game, box/manual/overlay/cartridge checklist, price (in case I need to resell) and origin (in case I need more) Lately I've added some extra details like label variations.

I'm glad it looked fixed at least for a minute Check with a multimeter each pin from VDP to that VRAM chip in special, it's probable one pin is doing false contact. Don't forget to do cleaning with alcohol and a toothbrush around the VRAM and VDP.

I know that I've played some truly awful games. But fortunately I've forgot completely about them

There is a quick and dirty solution for these difficult PCB. Just cut chip pins from over and solder the new memory over that.

It is pin 4 (AD6) from TMS9928 going to pin 2 of a 4116, the Colecovision schematic that I have reads that the corresponding 4116 is U13 Check with a multimeter the connection from TMS9928 to 4116 just to check that is the right VRAM. Where you see TUPL (ASCII 54, 55, 50, 4C) it should read TURN (54, 55, 52, 4E,) in Z80 that is bit 1, but Texas Instruments reversed the bits for its chips, so it is bit 6 of TMS9928.

It sounds like you're trying a PAL Colecovision with a NTSC TV set.

Well, at least it will get out this year . I believe that never was a game more expected than DKA

Thanks a lot, J-F! So two scores in a row , a silver Q*Bert and now this one

Hi everybody. While taking the pictures of my Colecovision collection (here http://atariage.com/...ion-collection/) I noted that my cartridge of B.C's Quest for Tires has label reversed vertically with respect to my other blue label cartridges. I've researched this a little more and it's noted in RF generation http://www.rfgenerat...U-024-S-00111-A (the one I have) http://www.rfgenerat...U-024-S-00110-A (the right one I suppose) So my question is: are the two common? or one is rarest than the other? Thanks.

As mint an Activision prototype of a released game could get a price between US$90-US$150, higher if the game is rare, hard thing as Activision titles are pretty extended. I would suggest US$80 for this one. Check this old thread http://atariage.com/forums/topic/200224-activision-prototype-cart-river-raid/

Thanks, I was lucky to find the lot. Yes.

Well, I've played with my scanner settings to get the clearest/brightest pictures. First the 32 in 1 V-case cartridge: Now the 32 in 1 with switches. If I remember right the switches are configured for the Donkey Kong hack that instead of a gorilla has a big smiling rabbit. In both cases, top letters have its bottom towards back of cartridge.

Thanks for sharing! Simply amazing!

In fact because all the bugs in software and computers, the world ended. But afterwards started another exactly the same, so nobody noted it.

Thanks. I'll take it in account for the future if I become a more serious collector. Currently I have a serious trouble with space (part of the reason why I don't have collected CIB games)

Thanks, Luc!

Hi everyone. A little more than a year ago I've started collecting Colecovision loose cartridges, just for fun, in fact I started with the better games (I think) and then added one, other one, another one and without warning I started a collection that finally I've completed in May/15/2013 (obviously not including the S.O.S cartridge, given that only one or two exists) Some items were pure luck, like the Super-Sketch (Sketch Master) that I don't even intended to get. The Wizard of Id Wizmath and Q*bert Qubes were other two very difficult to obtain. Besides I've got five Q*bert before getting one with good label and in the process I got one with a silver label (not here because I think it doesn't fit along the other Parker Brothers) It took me one hour to unpack, fifteen minutes for the pictures and another hour to pack again So enjoy it! [bTW, I have some duplicate Colecovision homebrews, but with one is enough to show ] Added Jun/07/2013 Now my Colecovision cartridges duplicates, most are in not so good state, primary cause of having to order more cartridges. This picture includes the rare Q*bert with silver label. Also the Facemaker and Smurf's Paint and Play Workshop cartridges doesn't work. Also included three Atari cartridges that doesn't work. My collection of homebrews (part 1), including the Zombie Near game I wrote (I've four of this one ) My collection of homebrews (part 2), including the Princess Quest game I wrote (I've two of this one ) And here is my very small Atari Collection. Update Jun/11/2013: My small MSX collection, including the games I've wrote. Update Jun/26/2013: A recent addition to my Atari collection, plus all the other platform cartridges in my collection. BTW, someone used a permanent marker in the Total Recall cartridge . For being my first two NES games, I choosed the most unplayable games I like very much the colorful label of the Atlantis cartridge for Intellivision Update Aug/25/2013: Recent additions to my Sega Master System collection . Only Out Run 3D has the manual, so technically it is the only CIB. Update Mar/06/2014: Just taken pictures of all my homebrew collection without duplicates: Update Jun/21/2014:
