the ground plug is always missing from cabs when I buy them, last owner said it was because he didn't have a 3 pronged outlet :banghead:

I think this is primarily the case. Gah! I don't like the idea of the power not being properly grounded. Another thing to be fixed -- Added to the list!
I've been google-searching and reading, looks like my RAM error is pretty common. Next thing for me to do is check my voltages on my PS as well as DRAM chips. That will give me more of an idea of where the problem lies. If it's the PS (hoping not), I'll have to rebuild it or decide on upgrading to a new PS (most likely a switching one, which I'd rather not).
If it's faulty DRAMs, I should switch from the 4116 to 4164 DRAMs anyways as they're easier to obtain as well as run a lot cooler. There are conversion kits out there I can buy that come with the power adapter to use with the 4164's (no need for the +12 reg and -5 from the PS).
The previous owner gave me a bunch of back-up 4116's, in case of any fail...so for the time-being if the problem is faulty DRAMs I can just replace the individual ones till I go for the full-on DRAM conversion.

WOOT! :applaud:
After checking voltages and poking around a bit, I found out that the DRAM in question had indeed failed. I swapped it out and it is all good now! No more crashes! I even threw in the alkaline batteries for now, till I do the battery surgery later.
So awesome!
First run after fixing it:
I could have done better but I had to get dinner started. I usually never go over 1 million on the first try, on my mame machine...what a huge difference! Love the real Robotron Wico's, it's like BUTTER!
