The '''IBM 5153''' (officially the '''IBM Personal Computer Color Display''') is the 13-inch RGBI colour monitor IBM introduced in March 1983 to pair with the [[IBM Color Graphics Adapter|Color Graphics Adapter (CGA)]] in the [[IBM PC (5150)]] and [[IBM PC XT (5160)]]. It produces a 640 × 200 monochrome or 320 × 200 four-colour image at 60 Hz and can render all 16 CGA colours, including the famous '''brown''' that lower-quality third-party CGA monitors typically reproduced as dark yellow.

The 5153 reduces the green signal amplitude by about one-third internally; this is the trick that produces "brown" from the (R + G) bit combination at low intensity. Third-party clones that drove R, G and B with equal gains showed dark yellow in that combination instead.

IBM 5153 Personal Computer Color Display

Manufacturer IBM
Type TTL RGBI colour CRT monitor
Release date March 1983

Compatible IBM PC (5150), IBM PC XT (5160), any CGA-compatible system
Dimensions 13" CRT
Model 5153

The IBM 5153 (the IBM Personal Computer Color Display) is the 13-inch RGBI colour monitor IBM introduced in March 1983 to pair with the Color Graphics Adapter (CGA) in the IBM PC (5150) and IBM PC XT (5160). It can render all 16 CGA colours, including the famous brown that lower-quality third-party CGA monitors typically reproduced as dark yellow.

Display Characteristics

[edit | edit source]
  • CRT: 13" shadow-mask colour tube.
  • Resolution: 640 × 200 (CGA mode 6, monochrome graphics) or 320 × 200 (CGA mode 4/5, four colours); 80 × 25 or 40 × 25 text.
  • Vertical scan: 60 Hz.
  • Colour interface: TTL RGBI — four digital lines (Red, Green, Blue, Intensity).

The 5153 reduces the green signal amplitude internally; this is the trick that produces "brown" from the (R + G) bit combination at low intensity. Third-party clones that drove R, G and B with equal gains showed dark yellow in that combination instead.

Input Connector

[edit | edit source]

DB-9 female TTL RGBI:

  • Pins 1, 2: Ground
  • Pin 3: Red
  • Pin 4: Green
  • Pin 5: Blue
  • Pin 6: Intensity
  • Pin 8: Horizontal sync
  • Pin 9: Vertical sync

Common Faults

[edit | edit source]
  • Convergence drift — colour fringing at the edges. Adjustable via the convergence trimmers behind the rear bezel.
  • Loss of one colour channel — dry joint at the DB-9 input, or a failed video amplifier transistor on the corresponding RGB output.
  • Geometry distortion — failed deflection-circuit electrolytics on the chassis board.

CRT Safety

[edit | edit source]

The 5153's CRT retains a lethal anode charge. Discharge before opening — see CRT Discharge Procedure.
