from Wikipedia:

The Magnavox Odyssey², known in Europe as the Philips Videopac G7000, in Brazil as the Philips Odyssey, in the United States as the Magnavox Odyssey² and the Philips Odyssey², and also by many other names, is a video game console released in 1978.

In the early 1970s, Magnavox was an innovator in the home video game industry. They succeeded in bringing the first home video game system to market, the Odyssey, which was quickly followed by a number of later models, each with a few technological improvements. In 1978, Magnavox, now a subsidiary of North American Philips, released the Odyssey², their new second-generation video game console.

In Europe and Brazil, the Odyssey² did very well on the market. In Europe, the console was most widely known as the Philips Videopac G7000, or just the Videopac, although branded variants were released in some areas of Europe under the names Radiola Jet 25, Schneider 7000, and Siera G7000. Philips, as Magnavox’s European parent company, used their own name rather than Magnavox’s for European marketing A rare model, the Philips Videopac G7200, was only released in Europe; it had a built-in black-and-white monitor.

Videopac game cartridges are mostly compatible with American Odyssey² units, although some games have color differences and a few are completely incompatible. A number of additional games were released in Europe that never came out in the US.

VirtualC64 emulates a Commodore 64 personal computer on your Macintosh. I wrote the software with two major goals in mind. First, I wanted to create an emulator that can be used as a demonstrator program in a first year or second year course on computer engineering.

To achieve this goal, I have integrated various debugging capabilities that let you peek inside the CPU, RAM, ROM, or one of the custom chips. Second, I tried to make the emulator as user friendly as it can get.

In short: VirtualC64 tries to combine the ongoing fascination of the ancient Commodore computers with the great user experience of today’s Macs.

Changelog:

Fixed in beta 8

• Joystick handler has been rewritten from scratch. It’s now message based and supports hot plugging.
• Fixed a race condition that could cause the emulator to crash during shutdown.
• Fixed some minor GUI issues.

Aries was backordered on the required 24 and 28 pin headers needed to finish testing, and the order just came in this past week.  Thus, I finally had a chance to solder and test the units.  Testing went well, and I can program the units with my Willem programmer.

Originally designed to hold a 29EE512 64kB EEPROM, I found a good price on Atmel AT49F001 128kB 5V Flash, so I made the necessary adjustments and tested with the new memory.  Testing went well, so I am releasing the design to production.

I have noticed one issue that I need to address.  Some CBM units have an RFI shield that doubles as a heat shield.  To perform the latter function, metal “fingers are stamped out of the shield that press on the top of the ICs.  I need to ensure the metal shield/heat sink does not contact any of the pins on this unit.

Sound fix diagram here. (pdf)

from Cristian Secară Homepage:

The first release (the +3) has a fatal hardware mistake: the 128K sound output is completely distorted.

• Tech explanation: the analog output of the AY-3-8912 sound chip was intended to be amplified by a one stage common-emitter transistor. In practice, they have forgot to put a resistor to the transistor’s emitter. The result: the transistor works in switch-mode – the sound is converted from analog multi-level amplitude to digitized two-level amplitude, same as the old 48K sound system.
