Hmm, this doesn't help you much, but I did a bit of poking around,
and here's what I came up with:
Harris, the current producer of the 1802, has the following documents
online:
Application notes:
AN6565 Design of Clock Generators for Use with COSMAC Microprocessor CDP1802
http://www.semi.harris.com/data/an/an6/an6565/
CMOS CPU Data sheets:
CDP1802A \
CDP1802AC|
http://www.semi.harris.com/data/fn/fn1/fn1305/
CDP1802BC/
High-Reliability 8-bit CMOS Processor data sheets:
CDP1802AC/3
http://www.semi.harris.com/data/fn/fn1/fn1441/
I briefly paged through the above data sheets to see if they might have file
numbers for any of the 1801 data sheets, but didn't see any. It was
interesting to see that at least some of these classic parts are now
available in PLCC's (I suppose this is the modern equivalent of the
Flat-Pack, roughly speaking.)
If you want to continue the search further, Harris has online data
sheets for much of the CDP18XX series (including the classic 1802
interface and memory parts), and maybe one of these will have a file
number for an 1801 data sheet. After you get a file number, you can
usually have the folks at Harris fax the data sheet to you.
