Yep, that's them!Do you mean the W27C512-45 EEPROM chip that was made by Winbond?
There's a topic on here about these here. These have been obsolete and out of production for some time.
The generic numbers 27512 and 27C512 normally mean EPROM chips (with a quartz window for erasing on top) and OTP (one time programmable) EPROM chips (which are still manufactured by Microchip).
As far as I know, all EPROM chips (with a quartz window) are now obsolete.
