The batch of V5 boards shipped to the assembly house yesterday. They should
be back in a month, and then it's a week or so to solder the piezo buzzer and
program the programmable logic. This has taken all of the available funds, so
I won't be starting Time modules until after I recoup enough to fund that
project. I have made that design a little more general. It should be possible
to program this little board to be the interface for a GPS receiver, or an SD
card, or a combination X-functions/double X-memory in place of the Time
module. It's only one-time programmable before anyone asks. I'll probably
be working on designing the GPS interface (basically a UART with big buffers
and buffer management) while waiting for the V5 boards to get back.

I don’t understand what you mean. What does that mean “one-time programmable”?
Do you mean it’s not upgradable?
What are these different options? Could you be more specific?
Does this mean that you can either ship the board to be a GPS interface OR an SD card interface?
Does this also mean you would work on an X-functions/double X-memory instead of the long-awaited Time Module and never come out with it?

This is very unclear to me.
