years ago I posted here
http://www.cpu-world.com/forum/viewtopic.php?t=9233&highlight=bell+mac8
about a WE212C CPU
but now I don't remember where I found this information!!

someone has better information about BellMAC-8 CPU?
I wasn't wrong when I posted the WE202 is the BellMAC-8 CPU?

I just got one of those the other day, a gold-top 212C-13! So it is a Bell-related product- neat!

Thanks! The schematics of the tutor should help to verify
if the WE212C-chip really is the MAC-8!
Here they used F-60789 as p/n of the processor but
its a provisional manual...
