But since I am new to this (I assembled my PILBox a couple of days ago) I don't have a cluo how to get the .bin file onto the HP71B. Unfortunately this is not easy. The C71 module is a 64K ROM, so you need either the rare FRAM71 module, or a (also rare) modified HHP 96k module to get a 64K RAM port to hold the C71 image, or a 64K EPROM CMT module (and asking a CMT programmer owner to program it for you :-) The last solution is probably the best, there are regularly some CMT 64k EPROM modules for sale on eBay.
