Sinclair ZX81 Chess by Psion

[jwse30]

I recently bought a lot of cassette tapes for my pocket computer and this was in the mix. It's a cassette for the Sinclair ZX81 (16k RAM) of Chess. It was made by Psion. Side A is Chess and side B is Chess clock.

I've no idea if it works, but I did run it through Audacity, and it is not blank. I don't have a Sinclair machine to test it.

I only have the cassette and the case (and its sleeve); there's no original box or instructions.

Would $10 plus shipping be out of line? If not, I like Paypal, but I cn also do a personal check or a US Postal money order.

Thanks,
