I’ve noticed that many Data I/O 29B units for sale are missing their PROM shield covers. Fortunately, all of mine still have them! However, for anyone in need, I’ve taken the liberty of designing a replacement. You can now 3D print your own cover to restore your unit. Designed This with Easyedapro PCB… I Was going to make it from a Circuit Board With a RF Shield But Exported the 3D Model for 3d printing since the thinner thicknesses of FR4 Was to Expensive. And if Data I/O did not have RF Shielding it was prob not needed. But was an Idea.


Compare to the Original Clear Data I/O 29B Programmer Prom Shield Cover to the Black 3D Printed Cover.


Fit In the 3D Printed Cover in the Data I/O 29B Programmer.
