The PDP-9, which is "two metres wide and about 75cm deep," [4] is approximately twice the speed of the PDP-7. It was built using discrete transistors, and has an optional integrated vector graphics terminal. The PDP-9 has a memory cycle time of 1 microsecond, and weighs about 750 pounds (340 kg).

The PDP-9 was DEC's fourth 18-bit computer, and the first DEC CPU to use microcode. A little over 400 were built. It was basically a re-implementation of the PDP-7 (built out of System Modules) in FLIP CHIPs; the PDP-9 'Basic Software System' manual indicates that most PDP-7 software will run, un-modified.

The PDP-9, the fourth of the five 18-bit minicomputers produced by Digital Equipment Corporation, was introduced in 1966. A total of 445 PDP-9 systems were prod...

2015年10月30日 · Owing to their large size and relatively niche application, these machines have never really seen as much attention in the retro computing space as the 12, 16, and even 36 bit machines have. I mostly hear them get brought up in the context of early UNIX development or due to their PDP-1 heritage.

pdp-9是“两米宽，深约75厘米”，大约是pdp-7速度的两倍。 它是使用离散晶体管构建的，并具有可选的集成 向量图形 终端。 PDP-9的内存周期时间为1微秒，重约750磅（340千克）。

2002年2月6日 · [This] is a hardware bootstrap loader for the PDP-9. Made by Tennecomp with a 19 inch rack form factor. It has a large black motor, which is activated by pressing the button on the front panel. The motor rotates a studded drum, 18 studs wide, and 60 positions long, using 53 of them. Like one of those music boxes.

The PDP-9 was a very popular, eighteen bit computer, with a cycle time of one microsecond. Over 430 were sold world-wide. Sites in Australia included Government Aircraft Factory, Australian Iron and Steel, Melbourne University Physics Dept, Latrobe …

The PDP-9 featured a speed increase of approximately twice that of the PDP-7. The PDP-9 was also one of the first small or medium scale computers to have a keyboard monitor system based on DIGITAL's own small magnetic tape units (DECtape).

El PDP-9, que tiene "dos metros de ancho y unos 75 cm de profundidad" es aproximadamente el doble de la velocidad del PDP-7. Fue construido utilizando transistores discretos y tiene un terminal de gráficos vectoriales integrado opcional.

The PDP-9, the fourth of the five 18-bit minicomputers produced by Digital Equipment Corporation, was introduced in 1966. A total of 445 PDP-9 systems were produced, of which 40 were the compact, low-cost PDP-9/L units.
