That's why I initially asked if you'd replace the CPU also. It was not totally obvious for me that you own hundreds of PLCC 68008.
These CPUs are probably cheaper than the sockets mentioned above?

I say V2 because they released a "Coldfire" family member before the version Nasta used. So yes, the MCF5102. I wonder which chip you mean. To my knowledge the MCF5102 is the first generation Motorola Coldfire CPU, hence the 51xx. Coldfire V2 is a standing expression for the 52xx range. O...

The struggle is real... qdos-gcc to the rescue. Unfortunately, the libraries still seem to come from the C68 distribution but at least the optimiser works plus there's a functioning inline "asm" directive which makes it easier to work around some of the more ....ahem... "interesting&...

Was the Miracle Parallel Printer Interface a SER-PAR adaptor?

The FLX68000 is an interesting chip for a future "improved Gold Card" but would only come close to SGC speeds. A potential point for the FLX68000 versus SGC would be costs and availability. But that alone hardly justifies the development work - also on the software side! Now, the Coldfire...

I recently ordered a bunch of MPE-GARRY 006-1-032-D-B3STF-XS0. Best pins for such a task, just frigging expensive. Indeed. € 4,23 and one needs two of them. But at least a possibility. SMD mounted turned pins on the lower side of the board, leaving the top side completely free. How can you leave th...

Actually, in the case of W5300, one should talk about a "TCP/UDP controller" rather than an "ethernet controller". That's to the point. And I think in terms of memory footprint and practicability, offloading TCP/UDP to a different CPU has the edge. Using an ethernet controller d...

Freescale was having another clear-out and I got a half pallet of this stuff. Cool... you are wizard in sourcing parts. ;) These are fast and run cool, but MAPBGA144 packages: After soldering Qzeros manually, I've become quite reckless regarding BGA packages, so I'd find it exciting if really fast....

Sounds very interesting! You will need a socket with long pins - isn't that a problem for 48 pin sockets? Or would you replace the CPU also?

Unrepresentative, personal taste: I wouldn't use the long card at all, unless I have to.

A medium sized card without through connector that just has the ethernet on the back and RAM would be better for me than that.
