Not familiar with that particular Eprom programmer, if it is BBC Eproms they must be 8K or 16K.
Eproms have a window in the top of them, if they have already been used they should have a sticker over that window, if you wish to re-use an Eprom you must erase it with Ultra Violet light in an Eprom eraser.
Please let me know how you go on.
Hope that is of use to you, if you have any further questions please contact me, I have an instruction manual for a Morley Eprom programmer somewhere, may be some useful information in there.
I may also be able to get some info from my collection of The Micro User magazines.

Hi Matt,
Thanks for the reply. I did a bit of research and found out how you could tell a eprom. As you rightly said they have the window, and also the more common ones have identifing numbers on them.
I gave using the programmer a go. I actually have the instructions and a Watford Electronics eprom deleter. Unfortunately I was unable to get it working, but I think this was just down to inexperience. I shall persist!
Thanks again for the reply.
