I recently bought a cheap "for parts" Intel Pentium Overdrive processor on eBay, the place where I buy the things I later regret™, because that's how the regrets are made. The seller described the processor as follows:
"For sale is a vintage overdrive podp5v 63mhz 486 cpu that was working. A few years back I tried inserting these into dense foam and it bent the pins. One pin broke off and is missing when I tried to straighten it out. This sale is for parts and as is."
I missed the broken pin part before buying (the $49.99 price distracted me), but the outer pins are all voltage and ground pins, right? Unfortunately, there are some cache-related pins on the outside as well. Hopefully this pin isn't one of them.
Well, I guess I'd better get busy pin straightening so I can get busy benchmarking...
Will I break any pins? Will it work after I straighten the pins? Will I be disappointed with the performance? You'll have to watch to find out!

![COMPUTER Mission: Possible... My MCA Apple ][+ Clone is Close to Working! (Computerized Start™ Live)](https://i.ytimg.com/vi/GS9Z20oby5Q/mqdefault.jpg "COMPUTER Mission: Possible... My MCA Apple ][+ Clone is Close to Working! (Computerized Start™ Live)
Last week, I finished installing new sockets into COMPUTER, my MCA Apple ][+ Clone, and then put all the logic chips back into place. I thought it would just power up, and it did, but it looked like the processor was not running code.
I put a modified Applesoft ROM Card into the system, which is hard-wired to boot Adrian Blacks memory test ROM, and the memory test did start to run. However, it would always crash soon thereafter. Seems like theres a problem in the memory section of the motherboard...
Thanks to having a second clone motherboard which is in working condition, I have a motherboard to test the RAM chips in to make sure they are all good. I can also check the chips responsible for addressing and accessing memory - one or more may be bad. But most importantly, this feels like Mission: Possible at this point!
Will COMPUTER boot? How many more bad chips will I add to the collection of bad chips from COMPUTER? Will I get to play a game? Youll have to watch to find out!
