The Philips Videopac G7200 is a Videopac game computer with its own 9-inch black and white monitor and loudspeaker in the case, so it needs no television. It plays all Videopac cartridges, including the C7010 chess module, and has the same alphanumeric keyboard and two hand controls as the Philips Videopac G7000.[3] An eight-pin DIN socket at the back carries RGB, sync and sound for a colour television with a SCART socket.[3] The game electronics follow the G7000, but the clock, video output and power supply are different, and the monitor is a separate board with a high-voltage line output transformer.[2][5][6]
Warning: the G7200 contains a cathode ray tube and a mains power supply. See CRT Discharge Procedure before working inside.
Versions
[edit | edit source]Owners on the Videopac / Odyssey2 forum know four versions of the 7200 series: the Philips G7200 for most of Europe, a Philips G7200 for France, the Schneider 7200 and the Radiola Jet 27, both sold in France.[7][8] The French Philips version starts with QUEL JEU? where the others show SELECT GAME. The versions also differ in keyboard legends and mains plug, and every version has the RGB output.[9][1] In the UK the set was supplied without a mains plug.[3] MAME's notes also list the Philips Videojeu N60, sold in France, and French Wikipedia describes the N60 as a more compact version of the G7200.[2][8]

Hardware

Game board
[edit | edit source]The game board has the same Intel 8048 and 6810 RAM as the G7000, and its 8048 can be swapped with a G7000's; a G7000 chip only changes the start-up text.[1][2] MAME gives the G7200 two crystals, 5.911 MHz and 3.547 MHz, where the G7000 divides every clock from one 17.734476 MHz crystal.[2]
The G7200 has no PAL colour encoder and no composite video at all. The monitor is driven from the TTL red, green and blue signals of the game board, and the same signals go to the DIN socket at the back.[5][9] The game board is supplied with 5 V and 12 V.[5]
RGB output
[edit | edit source].png)
| DIN pin | Signal | Level | SCART pin |
|---|---|---|---|
| 1 | Status RGB | 3 V, 75 Ω | 16 |
| 2 | Earth | 4 | |
| 3 | Blue | 0.7 V, 75 Ω | 7 |
| 4 | Sync | 0.3 V, 75 Ω | 20 |
| 5 | Red | 0.7 V, 75 Ω | 15 |
| 6 | Status CVBS | 12 V, 10 kΩ | 8 |
| 7 | Sound | 0.2 V rms, 1 kΩ | 2 and 6 |
| 8 | Green | 0.7 V, 75 Ω | 11 |
Pin 6 carries no picture. It is the 12 V switching signal that tells a SCART television to select its external input.[9] An RGB cable needs a DIN plug with the "C" pin layout, according to one owner.[10]
Monitor and power supply
[edit | edit source]The monitor and the mains supply are on a board of their own, joined to the game board by a plug; one owner proved a dead console's game board good by running it from another G7200's monitor and supply board.[6] The supply is a switch-mode design with a TEA1039 controller and a BUX84 transistor.[6]
The deflection IC is a TEA1011 (IC1). It takes the horizontal pulse from the sync separator at pin 13 (point G on the circuit diagram) and drives the horizontal output transistor TS3 from pin 15 (point P). The line output transformer supplies the tube's high voltage and part of its heater supply.[11] Owners give the TEA1011 supply as 24 V at pin 2 and 11 V at pin 12, name R25 as the height control and R23 as a fusible resistor in the vertical stage.[12] The line output transformer seen by one owner was marked 11 SF 107 11720, No 133840; no replacement is sold, and owners take one from another G7200, an N60 or a Minitel 1 terminal.[13] Owners compare the monitor with that of the Minitel 1, which was also made by La Radiotechnique, and one replaced half of a G7200 supply with half of a Minitel supply.[14][13]
Controls
[edit | edit source]The on/off switch is pushed inwards from left to right.[3] Its red lever is a long sliding plastic part that runs below the tube; it is often broken or missing, and owners have drawn a 3D-printable replacement. The red knob of the G7400 does not fit.[15][16] The contrast control has seven positions and can reverse the contrast, so that symbols drawn in different colours stay distinct on the black and white screen. Philips's instructions give the best setting for each cartridge from 1 to 43.[3]
Known faults
[edit | edit source]- A power switch that no longer latches, or a lever that has broken off.[11][17][15]
- A dead supply on the monitor and power board, which is a switch-mode type and harder to repair than the game board.[6][18]
- No glow from the tube: a missing supply voltage, the TEA1011, the horizontal output stage or the line output transformer.[11][13]
- A picture squeezed to a thin band: the vertical stage round the TEA1011.[12]
- Keys 0 to 7 dead: a broken track at the bend of the keyboard foil.[17][10]
- Scrambled screen with no response to the keys or RESET: a dead RESET input on the 8048.[1]
The checks are on Philips Videopac G7200 Troubleshooting Guide, and care and the controls on Philips Videopac G7200 General Maintenance. Philips Videopac G7200 Capacitor Replacement Guide lists what is known about the electrolytics.
Documentation
[edit | edit source]Philips's English and German instructions and the French instructions are hosted and described on Philips Videopac G7200 Documentation. Owners refer to a G7200 service manual with a complete parts list, and one owner found a copy that lacked the power supply and monitor sections.[19][18]
