Are there BIOS versions other than 0xb796, 0x7931, 0x7adb?

[Peer]

Greetings everyone,

are there any other original/official Vectrex BIOS versions out there? Other than those with checksums 0xb796, 0x7931 and 0x7adb?

I am not talking about homebrew patches, e.g. like the fastboot ROM, only BIOS versions that came with manufactured consoles.

Many Cheers,
Peer

Those are the only ones I know of from the production units.

The GCE HOME-ARCADE prototype might have another one. But would not be something people would normally have.
