Admit it, come on... you just want to run AROS on your A4K ;-) :lol:

How cool would that be! :-D

Would it run on a 486?

As long as it has an fpu... though a nice word to one of the lowlevel AROS hackers would probably get you a fpuless build... :-)

WTF, why don't you all just get an old PC instead, I mean, it's not even like Amiga/PC hybrid sharing files and desktop so it's just an old crappy PC really :eek:

[keropi]

@jose: the goldengate cards INTEGRATE to the amiga, sharing common resources and hardware... so IF anyone has a need for a 386/486 pc and has a bigbox amiga, those cards are excellent. It appears u never saw one in action...

[Jose]

@Keropi
True, never saw one in action:) But except from being able to spare space I don't really see the point...

@Jose

[...] just for the Geek factor [...]

That's the point, and it's as valid as any.

[Jose]

Ok, it's just that my geek side doesn't normally involve PC's

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...

The GoldenGate is a great card, I had one myself in 1998 when I was going to build the ultimate Amiga tower of power in the world. Well my plan halted when it was not compatible with the Elbox 7-slot backplane I had back then.

To be running it in its full potential you should have the external monitor switch wich can turn any desk into a rats nest.

@cv643d:

why pci slots on amiga are evil???  :lol:  :lol:  :lol:

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.

A bloke I went to college with had a Cyrix 486 CPU that clipped over the top of his soldered on 386 CPU.  This was in the early 90's.

[Jeff]

I had two of those. The Evergreen model 300 "Rev to 486" clipped on to the A2386 and ran at 75 mhz. It needed a dos driver to load the clock tripler at boot up as I remember. I sold that long ago.

I still have the Cyrix 486slc clip on somewhere that runs at 50 mhz. They both worked pretty well, however are dog slow by todays standards.

I would still love to have a working bridgeboard setup for my A3000T again. It it ideal for it with lots of Zorro and ISA slots.
