Right here is the plan, we have a decent A600 accelerator, we need to make it fit in a much nicer to use Amiga like 1000/1500/2000 etc.
I presume the 68k SMD unit the A600 has identical pinouts to the 68k DIP package. But are the voltages the same also?
If the voltages are the same is it possible to buy kits or components to build your own bespoke SMD to DIP adaptor?
I find the A600 power connector to be a weak point in the design and there is no way I am spending hours doing things on Dpaint only to have it shut off if the machine is moved 1mm or something stupid (all 4 I got were like this. Horrible cheap nasty machine!)

1500/2000 Amigas have a lot more easier to use Accelerators than converting an A600 accelerator to match the 68k socket. I just wonder if the height of the adapter + ACA630 would have left space (in height) to use any other expansion...
A600 is a fine machine with flaws like the soldered CPU. Since ACA630 is out... It rox and it's stable as a rock. If the A600 is horrible cheap and nasty as you said... it's your opinion since many of us just LOVE our A600 and think they are nowadays cute little beasts.
Just make some search over EAB and you'll see that the thing you ask has been mentioned lotsa times.
Apart from that... you can wait for the upcoming (if Jens decides to produce it) ACA520

I made something like this 15 years ago. The CPU voltage is the same but A600 do not use VPA/VMA lines to talk to CIAs. This interface must be implemented on the adapter board as it's not present on an accelerator.
Here's a picture of my adapter:

The question is:
Do you need this right now ?
The ACA630 costs about twice the (small) ACA1230 and the proposed ACA520 should be in the same price region.
So by the time it gets released you'd be able to buy an ACA520 as adapter + an ACA1230 to connect to it for the same price as an ACA630 (which will need your DIY adapter) and you get more RAM and an IDE-interface thrown in for free.

Ah OK didn't check price of 630 and didn't know it isn't 100% logically compatible with 500/1000/2000 etc so it's a no go.
I'm not really interested in A500 stuff either. I don't want to type lots of code on the nasty A500 or A600 keyboards and find both ureliable to invest in parts I can't use on my 2000 or 1000 that's all, otherwise theyre fine as gaming rigs for classic gaming :)
Also 020 is usually too slowwwwww so unless it's 28mhz like Blizzard 1220 I'll pass. Also needs to fit on A1000 CPU.
