Two ROMs from VectorEyes's collection, with professionally-printed labels marked ETL 3800A ROM 1 and ETL 3800A ROM 2. Presumably related to this: https://shop.unigreenscheme.co.uk/gener ... -lab-x4x18 (see also: viewtopic.php?t=5098)
WIth both ROMs installed, you can do *ROM then *EXEC !BOOT to get a menu. I guess you need the hardware to do anything useful with this, but the convolution option with a generated waveform does something that looks about right.
You can also do *SDUMP. On b2, the emulated Beeb then gets stuck with the shift lock light flickering away. I didn't investigate; I assume this is another thing that you'd need the hardware for.
Looks like ROM 1 is supposed to go in a lower priority socket than ROM 2, as *SDUMP craps out if you have ROM 1 in a higher priority socket.
