The cost is based on getting a batch order of 30 boards. I'm not
keeping an inventory here. I'm just designing this and looking for
people to join in. That way we can get it at a reasonable cost. This
design includes all the accouterments.
The vertical rows do seem to have a bigger limitation. Maybe it's better
to go with the grid pattern. I was thinking about adding the decode
logic too. But I haven't decide on whether to use discrete TTL logic or
a common PLD to save space.
Since this my hobby, I'm doing this mostly for fun and whatever bonus
there is at the end is alright by me :)
I'll be glad to help out on any design you might have. Send me email
offline and we can talk some more.
