@PhilC I'm surprised you don't have a magic solution for me. :cry: I guess my weakness here was having a lot of spares from the remake build and my ability to assume I had all the non-descript parts... Lots of 05, 06, etc used in the remake. Then Exxos slips in the 07 that totally passed me by.. :o If I could give up all these assumptions I would be miles ahead. :thumbup:

That was exactly my problem too Paul. You could always make an 07 with discrete components :D

Na.. not that desperate... believe I'll run all my plugin chips through the remake to insure they work, maybe give the board a good going over with the microscope to check for any irregularities. :)

Sounds like a plan to me Paul

So the first of my three boards is now assembled and metered out all ok with the pullups etc but I've yet to get it to boot into Diagrom properly.
Having a quick look and it looks like I have a couple of issues with the address bus. So once I get time, as real life keeps getting in the way, I shall meter put all the address and data lines. No doubt I've forgot to solder something as usual :lol:
Btw, for my first board, I chose to go the plcc route for glue, mmu, etc but for the next board I'll mount the smt versions of those chips, so we can get a good test of all the possible assembly options.
I've also put both a simm socket and the falcon ram headers on this board but the next two are likely to be simm only affairs.
More to come soon.
(Wish I had an LA)

@PhilC ,you will be happy to know I didn't use any your magic smoke. :) I'm thinking of using your plan and try a SMT glue and emu on the second board which arrived today, thanks @exxos.

@PhilC
Dude, really!!
I'm not doing magic smoke ATM anyway, I'm just breaking stuff so it doesn't work at all :sigh:
Hence the saying "If it's broke, there's no magic smoke"
