Atari 2600 CX-42 wireless joysticks receiver
| Preliminary Information | |
|---|---|
| Release Year | 1983 |
| Batteries | receiver uses no batteries, wireless joystick controllers use standard 9V batteries (1ea.) |
| Mounting Technology | all through-hole, has output cables |
| Capacitor Types | few electrolytics, few ceramics, many poly film |
| Destructive Entry | No |
Known Issues
Symptom(s) and/or Problem(s) to be Encountered
Causes
- natural wear, ageing, hi/lo temp. cycles, decades of humidity changes, attic/basement/outdoors, artificial factors, vibratory track damage, a few caps optionally supply thus rely upon the power rail in the [optionally-powered] Atari console (when/if applicable, used as designed: as power pass-through and not just for the controller signals)
Solutions
- replace for chemistry, preventative, or damages
Disassembly Notes
screws, case/shell is 2 halves (a top, a bottom) plus a front plate with cosmetic model info & a back plate with telescoping antenna, ⅛in. (3.5mm) power input jack/output cable, small NEC 78L05 adjacent to 9V input jack regulates 5V for this receiver circuit.
