Two Activision prototypes down the drain

I was the winning bidder for more than a week on these two.

Now I'm really boggled that two users with ratings under 10 would bid this up over $250 (my limit was $150, they are known games and probably not different from the final versions) so either they are two stupid sh#%s who got in a bidding war or these are mult accounts for some other more well known proto collectors (but not two that I recognize).

Im not real familiar with prototype stuff but I hope to own at least one someday.But do the eventually die or something?Like the program erases of the eprom or something like that? :?  :?

 

It's always possible, but in my experience pretty unlikely. I've seen prototypes that haven't been shielded inside a cart and even without labels over the EPROM windows they still can be read fine after 25 years. Obviously it's a good idea to dump the prototype just in case, but odds are pretty good that if you get your hands on a prototype you'll be able to read it.

Unless you happened to buy it from a certain dealer in Vegas that decides to take it apart to just look at it, and then put it back together bending the pins in the process. :ponder:

I think I read that when these EPROMS were made, they were specified to hold their program for at least 20 years. Personally, I haven't had any die on me...

I've never had an EPROM die on me. I've had one where the board had traces cut (so I assumed it was a dead EPROM until I took a closer look) and one where the pin was broken (you all know that story). However I've never had a proto where the eprom had bit rot, and I've handled ALOT of protos over the years.

At the moment I'm trying to fix a Mission Survive cart but the Video Gems people used a particularly unusual type of EEPROM (a 2332 IIRC) so I can't find a way - yet - of reburning the data. I think I'm going to have to use a compatible 2532 or something. The cart itself shows every sign of bit rot, though - the EPROM looks fine, the connections are fine, but it consistently does the wrong thing.

 

Maybe the EPROMs used by Atari bods are a better quality than the EEPROMs used by small volume publishers?
