Re: A TF1232 happened
Must have been those processor pixies, like the ones the shoe repairer had in the fairy tale.
:lol:
:lol:
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

So a little more explanation i guess. I still think FPUs are pretty useless but i wanted to do a few other updates on the board actually so this helps.

You guys realize you can just add an FPU to the A1200 motherboard and it'll work with TF1230?patracy wrote: 10 Apr 2023 22:16 I saw Chucky had posted this on the facebook. I'm interested in one when it happens!

Re: A TF1232 happened
But only at motherboard clock speed which is more pointless-er

Re: A TF1232 happened
a FPU? Useless!
Coincidentally there has been a MC68882RC50A PGA sitting on my desk, been wondering what to do with it since I noticed it in a drawer last week.

Re: A TF1232 happened
You just need one extra wire to run it at 28 MHz which is already available on the motherboard.

Re: A TF1232 happened
@terriblefire may I ask You to take a look on compatibility issue of the CPUs with 1F91C mask - have problems with them on TF1230, display remains black, card doesn't boot when CPU with this mask is installed. Other cards working great with them, have tried TF330, TF536, TF534 so far....
TF1230 doesn't make trouble with CPUs with older masks like 0G40W works great otherwise...
PS
also of You have a spare 1232 PCB left - will gladly take one for test purposes
