I had to use my Weller 100/140 watt gun to generate enough heat to get

Yup, highly likely replacing them will fix the computer.
Be sure to get high-temp, low ESR caps for the replacement.
A lot of pwople are selling totally pedestrian caps as
low-ESR on eBay and such, but they are actually junk,
and not suitable. If the machine works with them, it won't
last long. The proper units are available from Digi-Key
for under $2 each. You just have to scan for the low ESR
rating.

Hi Jon,

I ordered from Digi-Key. Their part number is, 493-1467-ND.

The caps are rated at 6,000 hours, @ 105 degrees. Ripple current is 840 mA.
The impedance is 87 mOhm.

There were other choices with lower impedances but they were rated at
shorter lifetimes.

Thanks for your reply.
