     12C507? have I missed something?
     
     I've been using the 12C509 JW for prototyping and 12C508 for 
     production - Not had any problems other than those of my own making!
     
     Remember that with the internal RC, the clock variation over temp and 
     volts is large, so even with the oscillator calibration word, by -30C 
     (no volt change) you can be a good few percent out from 4MHz. The 
     internal clock is great for reducing RF emissions.
     
     Remember also, if you want GP2 as an O/P, setup OPTION so it isn't the 
     timer I/P as well as setting TRIS.
     
     That's the only two things I've had to learn the hard way (ie why's it 
     not working??)

Dear Picsters:
     
I'm looking for people who've actually used the 12C507/8. Has anyone got 
any feedback as to the product release status, number of gotchas, or 
inventory/price? I thought these were real, but I can't seem to find 
them. Also, I'd like to know which development tools people really like 
with these.
     
Thanks in advance for your support.
     
Regards, Kris
