Nope - the 11/03 used the WD Chipset (what was that chipset called?) with the DEC MICROMS to make 'em PDP11/40-ish. The 11/04 is closer to the 11/34 in design. MSI and SSI TTL 7400 series chips. The 11/04 was designed to replace the 11/05, 11/10 which used mostly SSI TTL chips (74xx). Bill Most 11/04's in non-industrial control use were upgraded to 11/34's or 11/34a's (a simple swap out of cpu boards, basically). Bill -- Bill Pechter | "The postmaster always pings twice."
