IC Tester is electronic device for testing ICs (integrated circuits) and may test some others electronic elements with appropriate addon.
Device is connecting to parallel (printer) port at computer, currently you can connect it to PC and Amiga computers.

Something about price, by my estimation all listed parts in table should cost about 25 dollars.
In that price isn't included price of printed board and optional parts, in most cases you probably make this board by yourself.
In that case you should spend about 5 dollars, otherwise you can spend up to 30 dollars.
When you manually making board, in PDF document are printed board layouts, when printing check that Fit to page option isn't checked to get ratio 1:1. If you need change something on board, use PCB file with appropriate free software to modify it. See download section.
Dimension of board is 100 by 93 millimeters, +/- 1 millimeter variation isn't catastrophic important is that holes for IC1 to IC6 match.
