RE: HP-71B IL Module Version
I purchased a bare chip, with firmware version 2.1, from Jean-Francois. Older schematics I used to wire my board showed SW1 and SW2 which in the latest hardware is JP2 and JP1 respectively. Per email from Jean-Francois SW1/JP2 is reserved for HP-71B IL modules versioin 1A which have a timing problem with the PIL-box. SW2/JP1 in my firmware version selects between 230 and 115 kbps.
Try CC41! |
