Obviously one should do websearches when they bring such things home.
Because it can be surprising how often one can find a manual online,
be it from the manufacturer or some third party. If the item has some

might find some value in keeping that 1975 calculator going, or that

Not working... But, it might be a good deal if the CPU is still good - in
the past, I've seen 4004 chips go for upwards of $100 USD on Ebay.
