Sure. The 8741 is a member of the 8048 family. The '7' in the part
number indicates an EPROM instead of mask ROM. If I remember correctly,
the 8741 is a shrunk-down version of the 8748 (8048 + 2k EPROM) which
was particularly suited for non-CPU-intensive processing.

A good reference, other than the Intel data sheets, is Adam Osbourne's
\fI 4 and 8 Bit Microprocessors \fR or something. It's an inch thick
book that sells for about $20 (in a brown cover with what looks like
timing diagrams all over). This will give you a pretty good summary of
most common 4 and 8 bit (hence the name) microprocessors. I got it from
McGraw Hill Bookstores, but I'm sure that a helpful-type person will
get you and the book connected somehow. Have fun!
