Specifications

NamePhilips G7000 'Videopac Computer'
Made by
  • Philips
  • the G7000 was originally developed by Magnavox as Odyssey2 (successor to their Odyssey videogame system). Magnavox was then bought by North American Philips (N.A.P), subsidiary of the european Philips company
Released1978
  • was produced until 1984, when N.A.P decided to quit the videogame market
  • from board- and chip-labels, I assume that this particular machine was built in 1983
Additional infoTYPE G7000 / 22

Board-info
CPUIntel P8048H
  • the P8048H is a microcontroller coming with integrated 64 Bytes RAM, 1024 Bytes ROM, 2x 8 bit I/O-ports, IRQ-line and timer
Speed
  • 1.79 MHz
  • according to Hans Franke, the G7000's NTSC-version (the Magnavox Odyssey2), had the same CPU clock. So apparantly, the video circuitry is clocked independently from the CPU in both variants (which is, of course, the best solution for compatibility)
RAM192 Bytes
ROM
  • 1024 Byte 'bootstrap ROM' integrated in the Intel P8048H (which was mainly used to start the program from cartridge)
  • 30 pin cartridges ('Videopacs'), 2-8 KBytes capacity (see 'Media')
  • for carts greater than 2 KBytes, bankswitching was done
Keyboard/ Layoutnon-standard QWERTY membrane keyboard
  • 48 Keys + RESET (directly connected to CPU RESET-signal)
  • keyboard scanning was done via one of the 8048's I/O-ports
Graphics'video display controller' (VDC), integrated in Intel P8245
  • contains 64 character set
  • 144x96 Pixels, 8 colors (from 12 colors palette; 8 different colors can be set for either characters/ sprites and dark or bright background)
  • can create a 'background grid', characters (from its charset) and 4 independant sprites (which can be one color only, 8x8 pixels)
  • has a screw to adjust RF-output
  • this is a PAL-version; didn't find anything about the NTSC-version specs (which is the Magnavox Odyssey2)
SoundIntel P8245, again
  • 4 volume settings
  • 2 output-frequencies (983 Hz, 3933 Hz)
  • can loop sound, can generate noise
  • controllable via P8245's registers
  • there was a voice-module with SP0256B speech synthesizer and sample ROM available
Media
  • Cartridges via 30 pin connector on its top
  • carts had 4-8 KBytes capacity and were called 'Videopacs' (thus the 'Videopac Computer'). Furthermore, the carts could be exchanged while the machine was running (!) - that was because there's no POWER-switch - you had to pull the plug
  • carts came with a handle to pull them out easier
Input/ OutputIntel P8048H used for I/O as well (reads joysticks, scans keyboard)
Miscellaneous
  • The G7000 was the european version of the Magnavox Odyssey2, and suprisingly it was much more successful than its US-counterpart. Originally developed by Magnavox (a Philips subsidiary), it was introduced in 1978 as an opponent to ATARI's VCS 2600
  • It was called 'Videopac Computer' because of its cartridges, the videopacs. They came with a handle (to easier pull them out), and could be exchanged while the machine was running
  • Due to its success in Europe, there were different variants of the G7000, some coming with external power-supply or detachable joysticks. Later introduced (but little successful and thus rare today) were the G7200 (with integrated b/w-TV), the N60 (with a smaller case) and the G7400 (codename 'G9000', with slightly enhanced graphics and sound)
  • The machine has a RESET-key (as part of the keyboard), but no POWER-switch! You had to pull the plug to turn the machine off
  • Reliable information on this machine is hard to find. Most of the G7000-specific data listed above was taken from Dan Boris' Homepage, which seemed the most authentic to me. Should you have any additions, feel free to contact me!


'Superbee' screenshot (4 KBytes) 'Invaders from Hyperspace!' screenshot (6 KBytes)
Two games I owned back in the days, when I had a G7000 as a child: 'Superbee' (left) is a distant 'Nibbles'/ 'Tron' relative - as a bee, you have to collect fruits, which turn into bars after that. Needless to say that touching these means instant death, and that it gets more difficult, the more fruits you collect (not to mention that game speed increases after a while...). On the right, 'Invaders from Hyperspace!' (aka 'Laser Wars'), which was a cool 2-player game. Except for the players' ships, the playfield contains ten moving objects (asteroids?), which will change their color when hit by a player (or one of the two UFOs contantly appearing). The goal of course is to change them all to your color, while avoiding the asteroids or getting shot - tricky, but it's great fun!
