![COMPUTER Mission: Possible... My MCA Apple ][+ Clone is Close to Working! (Computerized Start™ Live) @jdmcs](https://i.ytimg.com/vi/GS9Z20oby5Q/maxresdefault.jpg)
Uploaded September 2024 | Updated September 2026, 1 week ago
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 Black's memory test ROM, and the memory test did start to run. However, it would always crash soon thereafter. Seems like there's 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? You'll have to watch to find out!
