Could you provide documentation on how your devices are marked (EPM3512AQC208 & EPM3512AQI208)? This will help us mitigate counterfeit components. In addition, is there any change Intel could fabricate these devices again?

Hi MCaso1,

Effective July 28, 2003, Altera will transition from a single mark to a dual mark on its MAX® 3000A products. You may refer to the Customer Advisory ADV0306 for more information.

In addition, please be noted that Altera has its authorized distributor to sale Altera Devices. If the customer got the devices from formal Altera Distributors, they should be valid Altera devices. Otherwise, Altera do not ensure the device quality and do not provide the further service. Here is solution published for your reference:
