WTB: 486 Bridgeboard

[Plaz]

Back when I once had hopes of getting one of those too, I saved a few old Kinston Turbochips just in case.

Kingston Technology's TurboChip 133 is a 5x86 CPU (Central Processing Unit) upgrade that upgrades a 486 DX2, DX, SX2 or SX system to a 5x86 clock-quadrupled processor technology. At 133MHZ, TurboChip 133 is rated at Pentium 75-Plus performance.

Basically it lets you pop out a 486/25 and turn it into a 486/133 with extra cache. They used to really speed up the old systems back when the Pentium 60/75 were the latest things.

If the Goldengate card is only 386 pin compatible, then I doubt this would have done what I hoped. It doesn't look like I'm ever going to use them now. Wonder what they might bring on ebay. :-)

the goldengate cards all have a soldered cpu...

That wouldn't stop me.... 22+ years of soldering thru-hole, surface mount and even mil-spec experience. :-D

If 486slc isn't pin compatible with a normal 486 though, then that *would* stop me. I never stopped to find out exactly what chip the 486 bridgeboard had. I had assumed it was a normal 486 flavor of some sort, not a 386 pin compatible crippled thing.
