Replacing A1200 Caps with Solid State Caps

[stachu100]

I powered up an IMSAI 8080 with the cover off that hadn't been on for years and one of the tantalum capacitors exploded and shot a chunk of itself across the garage and bounced loudly off of the door. It was very exciting.

Are you sure it was tantalum capacitor?
Not Aluminum electrolytic capacitor?

100% sure. It's not the first exploded one I've seen, either, just the first I witnessed exploding. The molten orange streak and projectile are something I wouldn't expect you could get from an electrolytic, though I've never tried.

As far as I know there is no tantalum capacitors inside IMSAI 8080... :confused:
Only aluminum electrolytic capacitors were used.
Unless someone did an extensive upgrade.
