Re: TED series video promo The Magic Voice cart could be used on the plus4. with an adapter cartridge, which needs to be designed and built. Plugs into the Plus/4 and has a C64 cart connector on the other end, where the C64 Magic Voice cart can be plugged. Essentially what it would need to do, is map and address translate the voice chip address accesses from the Plus4 address to the C64 address. Also include ROM space on it, so that the 364 speech ROM can be put on it. The C64 ROM on the cartridge would be simply ignored. Should be easy to do.
Re: TED series video promo Nice find! Actually, most of the things they told was true. So it is far from a real scam.
Magic Desk was planned, but cancelled.
Most of the mentioned SWs exists, except maybe the Wizard of Wor. As the 364 dropped, without speech the Wizard of Wor would hardly keep up with the C64 version, as they did not have TCFS or a programmer with similar capabilities
