SIMM Board Installation
The HP LaserJet 5 printer has four SIMM (Single In-line Memory Module)
slots. The HP LaserJet 5M printer has three available SIMM slots (the
fourth is used for the PostScript SIMM). Use the SIMM slots to install
additional printer memory and printer languages (such as the Adobe
PostScript language). For the HP LaserJet 5 printer, you can add up to 64
MBytes of memory (4 MBytes are standard). For the HP LaserJet 5M, you
can add up to 40 MBytes of memory (6 MBytes are standard)....

Serial Pin-out and Cabling Configuration
Serial Communication
Serial communication is simply the transmission of data one bit at a time.
With just one bit to transmit at a time, data can be transferred with a simple
electrical circuit consisting of only two wires. In this fashion an eight bit
byte is transmitted one bit at a time and the individual bits are reassembled
into the original byte on the receiving end. Bit transmission occurs from
the least significant bit to the most significant bit.
