Hi Al
These are 8041's. These are copies of Intel's 8041's. They are
similar to 8048's in code but have a port with handshake, similar
to that on a 8255. These chips are mask ROM chips but can
be connected to an exteranal EPROM.
As I recall, the major difference, other than the port was that
they could only use internal RAM ( but I could be wrong on that ).

Subject: Help in identifying chip...

I have a load of these chips from NEC... Can anyone help me identify them?
NEC D8041C
It's a 40-Pin DIP Chip. And I've been unable to find any information
on-line about it.
We've come into a whole load of 74 and 75 series TTL chips as well as load
of Relays and Power Transistors and other assorted parts.
Once I get them all inventoried, I'll make a website.
Hopefully listmembers looking for classic IC's will find this to be a
useful cache of parts...
