HI Peter,

There is a message from a once removed previous owner of this exact TX802, down
the thread 2 or 3 messages. It looks like a clock doesn't always want to start.
Many solutions to get the needed 4 MHz signal were offered, all within my means,
but I've become lazier of late and willlikely just let it run (at 15W I have
limited guilt). I doubt that this is the original battery, but probably ought
to change it - surely befor I do anything with the start up issues. Willlet you
know if it affects it.

I have responded to the ROM message separately, 1 message down the thread.

Thanks Again,
Nick

likely a bad battery.

slightly, so if you are a Rev-1, you most likely need / want all four of them.

for mailing them and a couple of bucks each for the chips is all. I am out on
the road right now so it would be a few days before I could get to it.
