HP15c Limited Edition REPLACE plan

[Divasson]

Regarding firmware, there are already the memory patches available for the HP15c LE - but we're missing the cable (hard-DIY solutions are available here in hpmuseum based on the current cable) and also the machine is easily "brickable". My two LE units are now bricked due to tampering with them, as well as all my HP30b but one (that I will NOT try to update evermore!).

The HP15c CE unit is a much better animal from that point of view - I have reprogrammed close to 450 units and I haven't bricked a single one. (Also: all of them with the same cable! It seems to be quite robust even if the design looks fragile over time)
