Spare Boards Needed

For some reason that escapes me, some DAP owners were able to convince themselves that the Expander boards were not needed in their units. Accordingly, there are many DAPs out there that are missing Expander boards. Owners of those boxes would like to put them back into original condition.

Now is the time to clean out your junk box and get rid of those boards (Expander and others) that are collecting dust in your shop. If you want to donate them to the cause, I’ll pass them along for free. If you want to sell any boards for DAPs, I’ll consider purchasing them at a reasonable cost and reselling them at the same price.
