 Well, I just unburied my mod.2 and the parallel port is a double row 34 pin
connector and used a ribbon cable. I just recounted the pins and it is indeed
34 pin. It's interesting to note that the HD and FDD had the same type of 50
pin dual row connectors.
 The display on the m.2 was also really excellent compared to other
computers of that time.
