[aprssig] Yaesu Memorizer FT-227R manual?

Does anyone know where a copy of the manual Yeasu Memorizer FT-227R  
can be found online?

I recently acquired one, and I'm trying to set one up for APRS.  My  
specific questions at this point are what is the pinout for the  
accessory port, and where is the memory backup battery located  
(assuming it has one)?

I'm assuming it should remember the frequency even when powered down.

A session with the meter and the cover off leads me to believe the  
accessory port pinout is:

1 - RX audio back in to speaker/speaker jack
2 - TX audio in
3 - PTT
4- RX audio out
5 - switched +V to power accessory


It looks like a really nice old rig, especially the power for the  
accessory - I can run a single cable into the TNC for power and radio  
connections, and a second RS232 cable out to the computer.  I like  
clean installations!

I know this is a bit OT, but I'm trying to set it up for APRS use...

thanks,
Jason
