After over two years, I have finally completed converting scanned docs for my BASICON MC-1N from JPEG (!) to ASCII and put up a small page describing this somewhat obscure INS8073-based microcontroller. The docs (posted _with_ permission) will probably be interesting to anyone who is looking for information on the INS8073. There is, naturally, a lot of material that relates specifically to the MC-1N and its memory map and its on-board peripherals (an 8255 PPI and an MM58174A clock/calendar), but the bulk of the manual is about NSC Tiny BASIC. One of the motivations for finishing the docs was to better understand the RB5X (INS8073 w/*3* 8255 PPIs and 8K of SRAM). The memory map may be different, but that's trivial to transpose. http://www.penguincentral.com/retrocomputing/INS8073/ If anyone has any questions, stories, ideas, etc., for INS8073 projects, I'm interested, on-list or off-list. -ethan
