I bought a programmer from ebay and I want to program 27C801 chips, but since right now I don't have any, I just want to test if the programmer is working ok. Here is a photo of my programmer: [br][img]http://www.mcumall.com/forum/uploaded/Otto/20108287360_willem-programmer.jpg[/img][br][size=1] 54.18 KB[/size=1] So, in order to test, I went to "Test H/W" tab and set the programmer switches like the picture below shows: [br][img]http://www.mcumall.com/forum/uploaded/Otto/201082873921_hw-test.jpg[/img][br][size=1] 51.29 KB[/size=1] But if I click on Help > Test Hardware, I get this error: "Hardware Error: Check power & connection". I have connected the USB and DB-25 parallel ports. Does this mean it's defective or what am I doing wrong? Thanks in advance.
