Quick update. I have finished routing the 030 board. I was slowed down by a chest infection which had me bed ridden for a week. Going to do a few checks then its time to get the rev 1 030 made by dirtypcbs.

Board has is an evolution of the 020 board but has the following upgrades...

68030 ...

FPU (PGA -> PLCC Socket) slot with CPSENSE wired up (so the FPU is detectable by the CPLD). The FPU is full 32 bit.

2Mb Static RAM 32bits wide (the CBREQ and CBACK pins are available to one of the 2 CPLDs). Its been wired for Zorro II.

IDE Interface in the Amiga 600/1200 style.

It has 2 schmitt trigger buffers. One for each clock line.

I also added stand off holes to keep the board from tipping out of its socket under its own weight.

The idea here is to give me something to develop from so there are a bunch of features on a 10cm x 10cm board. I had originally thought of using a single TQ100 CPLD but this is harder to solder for a novice than 2 64VQ chips. I may change this in later designs

This sounds really fantastic! Congrats on your progress, and glad to hear you're feeling better. Chest infections can be the absolute worst. (I had one for two months once.)

Congratulations! Would be good to see a video about a 68030@50 version ;)
