So then what device/configuration would you advise for a 
black & white 80 char wide, probably 20 lines, reader from
eg. CF, running from 2 to 4 rechargable AA cells & no-frills
miminal cost ?

The task is stated very vaguely; it can be anything from as simple as 
PIC/AVR to as complex as iPod/TabletPC depending on what the device 
should be capable of.
