EPROM for various Microprocessor boards on Studer A820 (custom - enquire)

NEW REPLACEMENT EPROM SETS for A820

Nagravox can supply new replacement EPROM sets using new high quality EPROMS freshly burned and tested. We can supply all accepted stable versions. This listing is generic due to the large number of models and variations. You should initiate an enquiry with full details of your machine so we can provide recommendations and a quotation.  Pictures shown are generic for illustration and not specific.  

What are the EPROM’s or PROM’s? They are a set of 3 or 4 permanent memory chips that contain the full machine program that runs many of the various microprocessor based boards on the A820 - all tape transport and audio control. The EPROM is a programmed ROM that is ‘burned’ electrically once and then can last between 15 – 30 years before it may need to be refreshed or re-burned. These days it makes sense to offer new EPROM’s freshly burned with the appropriate code.  Random error codes are typical example of a failing EEPROM set as is inability to boot up correctly.

Studer constantly updated and improved the actual code to improve the functions, fix minor errors, but also to add extra functionality such as speeds, equalizations and time code. Nagravox can offer all accepted stable versions.
