What do you mean by:
"he first board I could never get to work correctly"
Photos would be nice.

> Both of my TekMagic boards have XC68EC060RC60 chips on them, so I'm not sure how reliable the FPU/MMU could be on either.

Actually, both of these chips you mentioned have no FPU/MMU.
I have some 68060 (XC68060RC50 with FPU/MMU) cpu's NOS (new old stock NOT recycled crap) if you/anyone else is interested in backup 68060 - drop me a pm.

@Damion

Here's my story (June 2009 now), which I'm sure you're familiar with (going back and forth on gmail).  This has been going on for at least half a year (?) with some breaks:
- using 2 tekmagic boards
- one works 99% of the time, the other crashes randomly.  Using the same hard disk on both.  So the only thing swapped is the tekmagic board.
- the one that crashes crashes on the same motherboard (A2000 motherboard is ok).  So while the tekmagic can be picky about a A2000 motherboard, it should like this one, since it works with the 1st tekmagic 060.
Items testted:
- tested the CPUs (68060) on Quickpak and on my other Tekmagic 060.  both work fine.  So CPU is fine.
- the ROMs are also fine.
- the oscillator clock is also fine.
All 3 work fine on the "ok" board with the tested A2000 motherboard.
The main question, what else should I check on this tekmagic board?  I'm testing it on a system that likes the 1st tekmagic060 and on the upgraded rom 3.9.  I may try swapping the RAM but rather not mess with it.

It's very interesting about, however don't think that applies to my board:
"Then, I buy AmigaPete's A2000. Everything now works perfect, using the _exact_ same hardware and software combination (PSU included) as before, with the only variable being the motherboard. No more lockups with the PIV, and the machine is finally stable."

Joy, its going to be fun to watch Amiga users buy some of those Tekmagic 2060 boards off softhut.  I doubt they are being redesigned by GVP.  If they are new, they still may be fussy about proper A2000 motherboards.
