That was a relatively simple and economic way to get started, so I assume that commercial versions should also be available at reasonable prices. I've spent some time searching, but maybe I haven't used the right search terms or perhaps my terminology is wrong because I can't find anything but odd references on the net. I can't use a commercial service because I need to go to where the donor eproms are located and copy on site. Any ideas on where I can buy a copier, kitset or otherwise, and a ballpark approximation of price range? Cheers Billy 8-{) Edit: Eproms are MBM2764-30Z or equivalent	Billy T (70)

But there are a couple of (overseas) possible links in the first couple of pages. You could get the Silicon Chip (or even the older EA) article, and build their one without a kit, though it's the sort of thing which is easiest with a PCB. The local PCB manufacturers used to be able to supply the boards for EA and ETI construction articles ... you could try them. My Z80 development board had one EPROM socket wired as a programmer, but I only used it a couple of times, and that was from code entered with a hex keypad. Now that the EPROMs are cheap enough (like nothing, often) I never use them. I use only eeprom based MCUs and ROMs now, and the serial programmers are just so easy to build that it's ridiculous.
