Worth of an SST Board after cleanup?

robfeli007 · Post by **robfeli007** » 30 Dec 2020 22:55

How much is an SST board worth these days, considering how difficult if not impossible it is to find them? At least til you get one in a Mega ST, TT, or Falcon.

In my case, I managed to clean up the board after removing it from a severely mouse-damaged Mega ST4 (it will be going to e-waste) and there were no lifted or damaged traces. I've got a head-worn magnifier with light attached so I could find other places I had to clean other than what I could see normally. The SIMM sockets were spared the major damage. All that needs to be done is to replace the sockets that had the chips' legs rust off, which would be the ones holding the TOS, oscillator, 68030, 68881, and a couple others. This is quite a bit more work than I'm willing to do.

If this is in the wrong discussion area, please move it to the correct area.

Clean or not doesn't matter really. Non working needs great photos to determine if it is even worth to begin to start to bring it back to life. It sound that it needs a lot of work if it had that much corrosion.

Working unit is another thing.

It is worth exactly how much someone is willing to pay for it really. It is rare, that is for sure.

EDIT: It's a gamble since there is GAL and such on the board I presume. If those are not working the whole board is trash.

Old Accelerator board for Mega ST by Gadget by Small. 68030, FPU, fast ram, TOS on board. Running at 33MHz. Without cache memory though so not that fast.

Cool.. A 030 CPU has internal caches.. Plus stuff running in fast ram should fly at 33mhz. A TF536 runs 50mhz with fast ram so it would be a fair bit faster. No fpu , but like anyone's going to use it anyway.

I guess. It matches a TT in speed at least.

Here's three shots. First is before I cleaned it. Second is afterwards. Third is after I tried taking off some of the chips.

I had a SST-equipped Mega 4 many years ago, and really enjoyed it. Certainly it was a massive step up from a regular ST, and I wasn't anywhere close to being able to afford a TT. :D

In recent years I've regretted selling it, but I did so in order to be able to afford my Falcon, so I don't really regret it too much. :lol:

@robfeli007: I assume you're talking about this SST Board that has been posted in multiple forums already?

"Corrosion" would be an understatement. Even after cleanup it's highly unlikely to work. To be honest with you, I fully agree with what @mikro told you in the Atari-Forum.com thread.
