INSTALLATION MANUAL

P H Y S I C A L CHARACTERISTICS The PDP-I Programmed Data Processat is a high-speed, stored-program, digitul computer made

of modu lar, sol id-state circuits. Each PDP-1 is tai lormade to specific customer needs by select-

ing h e proper equipment from a 1 i s t of cenhwl processor and input-outpu t options. A iypica!

system insfu l lotion cou Id include one or more of the units described be low. In most cases sy s-

tem unitsure housed in standard Digital cabinets, However, some pieces of equipment, esps-

ciaJly hose thaidrequire writing surfaces or tables for accessory equipment, have specially de-

signed cabinets, Note that dimensions in the table are for complete units, sknding aione . If desired, units may be &ached to one another by removing end panels. Over-all dimen-

sions wi l l then be reduced by the wid* of the removed pnels (1 -1/4 inches &r side for sfan-

dard cabinets); weight wi l I be reduced by 45 pounds per panel.

ENVIRONMENTAL REQUIREMENTS The central processor and input-wpu t devices operate satisfactorily under ordinary cond i-

tions of humidity, shock and vibration in a 50 to 1 OO°F temperohre range. However, a 70 to

85OF range is recommended. Tolerable humidity is up to 80 percent. Consult the system heat

characteristics that follow in planning room air conditioning if required.

POWER REQUIREMENTS Eachunitof the PDP-I systemrequiresa seprate source of 105- to 125rolt, 60-cycler single-

phase power. (On specia t request, the cenfral processot can be factory-wired for 220-vol t,

one- or two-phase power or 50 cycle ac .) The power source must also be capable of ma intcr in-

ing consbnt nmina l current and supplying transient current. The electrical characteristics of

individual units appear in h e bble be tow.

tacles (or their equivalent) to mate with inpufrwtput equipment power cables. The same kind

of recepfacle, but with a 30-arnp current rating, is required for the cenfra I processor power

cable.

Fifty-wire shielded sigm l cables with Amphenol 1 15-1 14P male connecbrs at both ends inter-

connectsyskmunits. Anyspecialequipmentusedwiththesystemmust have Amphenol 115-114s

female connectors and 1 391 she1 Is to accept signa I cables.

Unless otherwise specified, power cables are supplied in 20-foot lengths, permanently wrred

atone end to individual units. Signal ~ables come unatbched in 25-foot lengths. Power and

sigm l cables measure 1 1 /I 6 and 1 3/16 of an inch in d hmeter, respectively . Power and sig-

nal cables enter cabinets through bottom pork. Cabling for a typical system instat lotion is
