Willow Valley Vending Posted March 22, 2018 Share Posted March 22, 2018 Is #1 the EPROM or is #2? What is the other one called? Thank you, Jonathan Link to comment Share on other sites More sharing options...
AZVendor Posted March 22, 2018 Share Posted March 22, 2018 Number 2 is the EPROM which has the software version on it and #1 is the firmware chip that you don't need to change. Link to comment Share on other sites More sharing options...
orsd Posted March 23, 2018 Share Posted March 23, 2018 Yup, #2 #1 is actually soldered to the board and you really couldn’t change it unless you can solder SMD well. Which requires some pretty pricey equipment to do well. Link to comment Share on other sites More sharing options...

Coinco BA30's and Vendo controllers v9 and later use that type of socket for their eproms. Link to comment Share on other sites More sharing options...
