For a small eprom ( 74288 and the like ) I used to burn them with a switch
setup.  Switches to select Address, Switches for Data, and a pushbutton to
write.

These days I use an M2L programmer :

The EZ-EP in particular

For old stuff or weird stuff I picked up a DataIO programmer for cheap.  Its
huge and noisy but actually has a computer interface.  Will program 2708s
and small TTL stuff like the 74288 and the AM27S19 ( which I have gazillions
of and use like crazy ).

There are also some kit programmers available but I dont have any experience
with them.
