Greetings all;
A new arrival joined us tonight, but it looks like he is suffering from a
very rough life.
A HERO-1, who was fished out of the dumpster (EEK!) a couple of years ago,
and rattled around someone's desk ever since as a curiosity. Fortunately,
I have a friend who was able to rescue him from this rather unpleasant fate.
Well... having managed to scare up some free (well, ok... uncommitted)
time this weekend I was able to spend some time with the new kid in the house.
Pulled his arm apart, and it turns out that the damage is not quite as
severe as it appeared at first, but it is going to require some extensive
work and probably replacement of the plastic shells.
Had to replace the trim pots on the power supply board as they were broken
(nearly off). Checked out all of the other boarsd and wiring, and it
looked like was ok to go for first power-on and pwoer supply calibration.
As per the manual proceedures, all of the system fuses were pulled and the
charger (from the other HERO-1 in the collection) was switched on.
The power supply/charger board calibrated without difficulty, and all
voltages were stable within tolerances. So the charger was powered down
and the fuses replaced.
Deep breath and hit the switch... click... whine... "READY"!!! and
"HERO
1.1" appeared on the display!!!
Most cool! He passed the basic logic function and keyboard tests and the
onboard clock/calendar were set and monitored for a time. This looks VERY
promising!
Probably all for this session... Extended logic tests and sensor
calibrations come next.
It has been a good weekend...
