Incidentally, why is this OT? The HP65 is certainly a
classic (pun
intended). It's also, IMHO, a computer (the internal architecture is that of
procrssor + RAM + ROM (albeit the ROM and RAM are on different
(serial) buses; it is user programmable). I can't think of a sensible
definition of computer which includes things like the KIM-1 and excludes the
HP65.

I'm repairing/restoring a HP-65 with severe oxidation-damage on the
cardreader pcb and a lose headwire.
This head was filled with white siliconkit so I was able to remove it and
resolder the wire (yellow one). After resoldering,I refilled it with 2k
epoxy glue, terminal resistance seems to be allright for both coils and I'm
now restoring the PCB traces. The head connection explained it self.

Rik,
can you please learn to quote? Your messages are indigestible for normal
human readers because there is no distinction between your response and
the message you are refering to.
