Do you have the overall specs of this new 97 MotherBoard ?

- PowerSupply possible from an USB 5V connector/cable ?
(my 97 has been converted to USB power, so no more need of that old AC powersupply that i do not have anyway)
- Will it keep programs into RAM after switch off ?
- Will there be some onboard flash memory to store programs ?
If yes, how much kb ?
How will we manage the list of programs available (dir/copy/delete ?)
- Will there be an USB connection for PC<w=>97 data exchange ?

The 97 board should run from a USB port as it is powered by 5V. But the port would have to supply enough current to run the printer and card reader.

It will also charge the battery from the original charger, and a replacement as long as the specs are the same. These chargers cannot supply a 'lot' of current because of the 97's over voltage circuitry which relies on creating a voltage drop when excess current is drawn from it.

I'm looking into battery backed data retention for it.

It has on board memory to hold the programs from 810 cards. I already have PC software available to manage programs via the USB port or via Bluetooth.
