If bit[0] of 07777 is a one, batch is running. If you want to interact with it, the source of the BAT handler is useful info for this. Look in the PDP-8 archives for it on ftp.telebit.com where it is or will be soon. Bits[6-8] are the software core size where 000 and 111 both mean 32K is available because they both mean the highest field available is 7. Bits[3-4] are the date base group year bits currently, where each increment is 8 years starting at 1970-77 going to 1994-2001. Since it's getting close to the end of the world, I want a definition for all the bits so I can at least double the lifetime, if not quadruple it. So please find me a bit or two, preferably in that word. Anyone know what all of the other 6 bits mean? cjl
