I think I now have the worlds supply of DB19F connectors :lol: :twisted: :twisted:

And yes, there are several layers of these in that box. They are PCB mount right angled to fit motherboards etc :)

I now need to go have a couple shots of vodka before I look at the bill for all this :shock:

I've got 800, and that's all the stock they had.. but this cost well into 4 figures to buy, so sure wasn't cheap.

Going wayyyyyyyy back to the TOS206 boards... Getting SMT 22V10 is near impossible, other than the Atmel ones which are a bit of a pain to program because of a power down on pin 4 (which programers seem to enable by default and hard to turn to off). So I have started a new board based on the ATF1502 SMT instead.

EDIT:

This one will use a 2 68K DIP's so instead of soldering over the CPU, this will be more pluggable and easier to solder I think. I guess it could still be soldered ontop of the CPU anyway.

Finished off the PCB and sent off for 3 from OSH in the USA ;) I also dug out my dev-board to develop the firmware which will run on the new PCB.

@Icky Sent me the MMU board as mentioned over in this topic which I will post in when there is some actual progress.

I nominated a new STFM board for this project, basically one with nothing else socketed as I am getting tired of dodgy connections on sockets, so this board will only have the MMU "socketed" With the FPGA board.

Also using my new desoldering toy, this may very light work of a otherwise annoying task :thumbup: The holes are extremely clean, and the socket literally fell out of the motherboard when it was done!
