I was looking at the standard one on ebay for $39.00 will that do what I need.. I see on the forum some are having trouble with the 27C16,32 ect.. so I want to be sure I get what I need....

Thanks.. Mike

Go Dual Power or True-USB. The Enhanced does not work on old EPROMs.

All programmers, include Dual power and True-USB do NOT support 2708 and some Sinclair 2716 (eg. TMS2716). They need a negtive voltage supply (-5V).
