Serial/Parallel Adapter

Combined serial port (of type RS232) and parallel port on one card.
Up to two of these cards (configured appropriately) may be fitted in the 5162.

Click here to see IBM's technical document for the card.
There is an error in that documentation in regard to the setting of jumper J2 - parallel port address/interrupt.
That error is on document page 20, where "Port 1" has been labelled as "Port 2", and vice-versa.
Accordingly, the first one of these cards in your 5162 should be jumpered per the photo below (Serial port 1 / Parallel port 1).

Serial port 1 corresponds to I/O base address 3F8 and interrupt 4.
Serial port 2 corresponds to I/O base address 2F8 and interrupt 3.

Parallel port 1 corresponds to I/O base address 378 and interrupt 7.
Parallel port 2 corresponds to I/O base address 278 and interrupt 5.

Enhanced Memory Expansion Adapter

Released about September 1987.

For the IBM 5170 and IBM 5162  ("for IBM Personal computer AT and the IBM Personal computer XT Model 286")

This appears to be the earlier released 'Memory Expansion Adapter' that has been enhanced so that it can also use 1 MB sized SIMMs.

Provides up to 12 MB (via twelve 1 MB sized SIMMs) of extended memory.
Some of the RAM fitted to the card can be used to 'top up' conventional memory.
Includes a parallel port and a serial port.

A magazine article describing the card is at here.

Some photos from an eBay item are at here.

The switch settings for this card appear to be here, but for some unknown reason, forteen SIMM sockets (instead of twelve) are described.




Fixed Disk and Diskette Drive Adapter   (second generation)

Combined controller for hard drives (fixed disks) and floppy drives.

This is the second generation of the controller.  The first was supplied in early model 5170s.  This second generation was supplied in later models of the 5170, and in the 5162.

Made for IBM by Western Digital.

Note that that document covers both the first and second generation controllers (2 sets of circuit diagrams).

Monochrome Display and Printer Adapter (MDA)

This card is designed to connect to IBM's 5151 monitor (MDA).

Connecting this card to a monitor that is not designed to accept MDA video/sync signals may damage the monitor.
The IBM 5153 monitor (CGA) and IBM 5154 monitor (EGA) are in that category (not designed for MDA signals).

The included printer port is hardwired to I/O base address 3BC, and interrupt 7.

Click here to see IBM's technical document for the card.

When this card is newly fitted to a 5162 (as the only video card), two things need to be changed:
  1.  Motherboard switch SW1 set to the rear position.
  2.  SETUP modified to reflect the monochrome video card.

Color/Graphics Monitor Adapter (CGA)

This card is designed to connect to IBM's 5153 monitor (CGA).

Connecting this card to a monitor that is not designed to accept CGA video/sync signals may damage the monitor.
The IBM 5151 monitor (MDA) is in that category (not designed for CGA signals).

The IBM 5154 monitor (CGA and EGA) will accept the CGA video/sync signals from this card.

Click here to see IBM's technical document for the card.

When this card is newly fitted to a 5162 (as the only video card), two things need to be changed:
  1.  Motherboard switch SW1 set to the front position.
  2.  SETUP modified to reflect the CGA video card.

Enhanced Graphics Adapter (EGA)

This card is primarily designed to connect to IBM's 5154 monitor (CGA and EGA), but if reconfigured via the red switch block, is capable of use with the IBM 5151 monitor (MDA) or the IBM 5153 monitor (CGA).

Unlike on the IBM CGA card, the RCA connectors, J1 and J2, do not contain video for a composite monitor.  Instead, J1 and J2 are part of the card's feature connector functionality (J4).

In the photo below, the optional Graphics Memory Expansion Card (plugs into J5) that provides additional video RAM, is not shown.  Without that add-on memory board, the EGA card has only 64 KB of video RAM, and that may result in some programs not displaying as intended (detailed here).  And CheckIt software has a problem with that as well (detailed here).

In the photo below, the switch positions shown on the red switch block suit an EGA monitor.

During the computer's Power-On Self Test (POST), the IBM EGA card will perform its own self test (a crude/basic one).  If the card finds a problem with itself (including video RAM), the card will cause the speaker to beep one of two possible error patterns: 1 long beep followed by 2 short beeps, or 1 long beep followed by 3 short beeps.
