6 slots X $5 = $30
manufacturing the board = $11.27 each
Time, cutting down slots and soldering in = 1 hour
My time, priceless.
$41.27 my cost, not including labor.
Selling for $40 to members of this forum.
Just goes to prove, no good deed goes unpunished.

Will you be planning any cards to fit in this? Just the barest of boards would be good.. Otherwise we'll have to be off to olimex for their overpriced ISA slot protoboards ;) Like I said before, a pre-cooked IO address decoder circuit space, the rest as proto area..

(That is if you haven't been put off..!)

Ouch! And this just goes to prove that a couple of words can mess up everything... I've seen people leaving forums and even the scene for smaller comments!

Is Littlejohn still with us? I just noticed his website went offline and he hasn't posted here for a while...
I am interested in one of these boards.

Since the sales of my expansion plane project has been less than stellar, I have listed the bare boards up for sale on Ebay.
You can find them by the keywords: ZX81/Timex Sinclair 1000 Expander board
