2. Printers.
a. Internal Printer.
1. Requires printer option including A52 or A55, and A51 assemblies plus the
printer bucket. Note that A51 has the printer character ROM (currently Revision
A).
2. Hardware compatibility considerations:
Printheads manufactured after 1978 are NOT compatible with the the A52
board (09845-66552) and must be used with an A55 board (09845-66555).
(9845B/C-2. )
b. External printers will work for lists etc., using PRINTER IS syntax, for full capabilities
they require an
110
ROM; all Revisions are okay (LPU presently is A, PPU presently
is C).
c. H-P Supplied Printers information:

HP supports only the HPIB version on a
98034A/B.
The 2631G
version requires a Graphics ROM and the graphics support boards.
2. 9876A; HP supports either the HPIB version, or the GPIO version with a
98034A/B
or 98032A Opt. 076 respectively. DCD does NOT support the serial
