Be aware that the github project linked in the first post is a different "Accelerator" to the one in the facebook image. The first is an experiment in interfacing a 68020 to the 68000 socket and has minimal performance improvement over the 68000 (using a separate fast ram expansion may help). The image is of a 68030 accelerator board with fast ram, FPU and IDE which is still very much under test and development (revision 1 has some PCB issues). If you click on the parent "terriblefire" directory of the github you'll see the tf530 project but it is only a placeholder for now until the board has been proven.
Indeed, developer has only just fitted an FPU and is having issues getting it to fire up.
The whole project is in very early stage, but he just started his first thread on eab forums... clever guy, feeling his way.
Basically he's trying to build small as he can, working up (eventually, no time frame) to a CD32 accelerator. Lots of stages in between.
So, it's not a project at this stage for people who want an off the shelf A500 accelerator, it's more of a tech demonstrator to show how Amiga devs can still develop hardware. It might lead to very successful boards, but you are quite right, it is not fair to anybody to say things or mislead things at this stage.
So, I'm sorry to give the impression the 020 board has RAM - it doesn't.
And Acii, the boards will almost certainly need some wire wrap additions, but that's fine by me. I'm still game.
