Next you'll tell me Fax machines are dying!
WWell, mine did a few months back. One of the gears inteh drum drive
broke up. Of coruse this is a real analogue fax machine, not of this
new-fangled digital stuff.
More seriously, I do ahve an Analogue fax machine here, a Xerox
Telecopier RX400. It's new enough to have a MOS ASIC for the mtoro speed
control, but everythign else is 741 op-amps and discrete transsitors. And
eys, the reduction gear for the drum drive did breal up. Fortuantely, the
tooth pitch is the same as gears used i nradi-controlled model cars, so
the local model shop could provide a couple of suitable gears, I then
tuyrend a mild steel hub to put them on. Works fine .
Well, it woudl work fine if I could find anything to talk to...
