PR77: Well, I did sort of finish it, meaning I got the features I wanted for my A500+/A590 combo. It only has cpu and memory, no ide controller (like mc68k's nice board and many others), as I insist on keeping my beloved A590 with scsi for my A500+.
I threw together a quick (flickery) vid showing its features:

If I were to improve it, I would most certainly move to newer Xilinx CPLD, which everybody else seems to use (I used ATF1508 and WinCUPL) and DRAM (I used some low cost SRAM which is sadly no longer in production), but for now I will stick with it as it works fine for me.
