About the DS3800HIOB1H1G

The DS3800HIOB1H1G is a printed circuit board manufactured by GE as part of the Speedtronic/Mark IV series. The DS3800HIOB1H1G acts as an Input/Output card, and has the following specs:

• three LEDs labeled imok/adr/lact. The first of these is amber, the second and third are red.

• markings along the edges of the board. Upper (A through J.) Left (10/20/30/40/50/60/70/80.) Right(JA/JB/JC/JD.) Bottom (6BA09.)

• chamfered corners through the top layer of the board only

• factory drilled through the bottom layer of the board

• eight jumper switches. Seven have the option of 0 or 1. One has the option of IN or OUT.

• seven TP test points. T6 sits by itself on the right side of the board. T1-T5 are labeled reset, data, dsync, sync, and com and sit above T7 (test) along the left edge.

• one transistor

• one switch

• male 90-degree PCB connector sits along the right edge of the board.

• two lines of spare PTH (plated through holes) available

The DS3800HIOB1H1G is manufactured with ceramic metal film resistors of varying values. It has several capacitors. There are multiple integrated circuits, including oscillators, DIP switches, and Eproms. Some of these include:

• Intel 68A9168P LD8748

• Motorola SN701S00NI85

• 68A7860 18.4320 MHz

• P8552DM74LS175N

• 74L5374N

• 745374N

• 4168S SN74LS29
