Which 68k-machine to get an 6888x from for my A1200 ?

Hello folks,

I am new to this forum, it's great ! Now, for my
first post, I have a question:

I have an A1200 with a Blizzard 1220/4 which I'd like
to expand with an FPU (68881/68882). Does anybody
know a non-Amiga machine, where I could rip an
PLCC-version out ? I'm here at a university and
we have dozens of various old machines (Mac, Alpha, SGI)
which are being kicked away now, so there might be
hope to find the appropriate FPU.

Also, are there any projects to build your own
Turbo-board I mean there are so many 030/040-CPUs
floating around for free, but the turbo-boards for
an Amiga are quite expensive  (at least for a student ).


Looking forward for your answers,

Adrian

Don't know with what price this one ends, but could be an option to consider.

This won't fit, it needs to be PLCC.

Hi,

just ripped an Mac IIsi apart and it had one
on the Nubus-board, but it's been soldered in
though  :roll: But I have someone to unsolder
it for me. (I know I could just buy the one
from Vesalia, but I will try this one first,
I like fiddling with old hardware ).

The IIci has a 25MHz 68882.

I will rip it out now for my A1200. The 030 has already found a new home in an former broken A3000T.

The IIsi has just the 20MHz-version, but I can
set the Blizzard to operate the FPU at just
14 MHz Was the 68882 in the IIci socketed
or soldered ?

It was soldered. But not anymore now .

How did you unsolder the tiny beast or did you just
rip it off ? And at what speed do you clock it ?
