IBM 705 Drawings

Here are some drawings for an IBM 705 system. Most are from the IBM 757 printer controller, one of the three I/O units I have complete drawings for.

These are large black-and-white GIF files. Most are about 2500x3000. They were scanned at 300 DPI.

Cathode Follower

Sample module

This is a sample module containing the 10's and 100's positions of the "buffer counter", which keeps track of the print position. There are 120 print positions on a 717 printer.

Power Supply

This is from the 705 Central Processor drawings, volume 6. (I have only volumes 2 and 6.) It shows the +140 power supply. Most of the supplies are similar.
