Locator EPROM IC chip for Revox PR99 mk2 mk3


$52.00 AUD


 Nagravox can supply a new replacement PROM using new high quality EPROMS freshly burned and tested.  

 What are the EPROM’s or PROM’s?  They are a permanent memory chip that contain the full machine program that runs the PR99 locator system on thePR99 MPU board. The EPROM is a programmed ROM that is ‘burned’ electrically once and then can last between 10 – 15 years before it needs to be refreshed or re-burned.  These days it makes sense to offer new EPROM’s freshly burned with the appropriate code.  Most of the PR99's out there are almost 30+ years old so one can appreciate that the likelihood of an EPROM error is pretty high.  Random error codes are typical example of a failing EEPROM set.

This listing is for 1 x PR99 EPROM

Nagravox is starting a library of obsolete and unavailable PROM's for Studer and Revox machines. We keep our own original masters and then also store teh actual machine code on file which we use to clone new EPROM's in an appropriate burner. All PROMS are double checked after the burning process with the original  machine code byte by byte.
