Hello all,

I've been given a HCR Electronics Eprom writer. I'm new to this and wondered a few things....

Can only certain ROMS be written on to? (I assume this is true and they have to be eproms?)

If 1 is true then.... How do I know a Eprom is an Eprom and not a regular ROM

Thanks.

Jon

Hi Jon

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.
