>Andy Modla has added Swords to his emulator of the RCA Studio II and related hardware.

I like the video clip, but after having more time to look at links and photos including some of the paperwork, I'd like to believe the RCA Fredotronic arcade hardware can also be emulated in MAME...assuming there is permission to support the tape data in MAME.
>Swords was developed by RCA for their Fredotronic arcade hardware in 1975. It was based on >the RCA 1801 CPU, a predecessor to the better known RCA 1802. It was location tested, but >never put into mass production. However, RCA did release the RCA Studio II home console in >1976 using similar hardware. To put the time frame into perspective, Midway released Gun >Fight, the first mass produced arcade game to use a CPU, in November 1975.
MAME is part way there to supporting the hardware. The cpu support is there, but unsure if other hardware components such as video need to be added first in MAME before the RCA Fredotronic arcade hardware can be emulated.

I hope more of the tapes can be preserved sometime later.
