They are actually called SP0256-AL2 ICs (with a zero), not SPO256-AL2 (with a letter "O"). Easy mistake to make. Even an 80s game manufacturer made the same mistake.
I use them a lot, mostly to repair ZX Spectrum and C64 Currah μSpeech synthesizers.
If they are from a reputable supplier you should be able to get a refund without to much trouble.
Those may be counterfeit chips originating from china; some sources have been caught selling counterfeit Commodore SID sound chips. I once had a chip supplier tell me that they do not deal with Chinese inventory due to widespread counterfeiting (relabeling)
Yikes! Did you ever get any of these chips to perform, or did you get your money back?
I'm just getting into project work with the Arduino microcontroller and I have one or two of these chips. I once built a working synthesizer for the Commodore 64.
What kind of project were you working on that you needed one or more of these chips?
