| John,
| Add me to the list of (very) interested people.
|
| I would really like to see what you have changed as there were quite a
| few changes and additions I would have made to the earlier board. Some
| you have already mentioned.
| Replacing the Dalas NVRAMs with standard static and discrete battery
| backup. (I am getting about 20uA for 768k and an RTC on another job. A
| button cell will last for around a year.)
| Use 5V flash rather than EPROM with in situ programming.
| Automotify (?) the power supply. Having done automotive electronics
| commercially, this is _very_ important.
|
| I prefer to use SMD and PLCC parts where possible and will probably have
| a PCB made since the cost vs. reliability makes it worth it in my view.
| I would be able to supply a PCB for around US$40 +p&p (which wouldn't be
| much) if others are interested.
| If there is interest, I could price up kits of parts too.
|
| Steve.
