I use an old, rather well-worn Needham's PB-10 for programming EPROMs. Lately, I've had call to program larger chips - and while my old beastie can handle 27c080's, that's where it tops out. I love the Needham's, and would love to be able to use larger EPROMs with it - such as the 27c160 or 27c320...
I know my programmer can handle 16bit EPROMs (like the 27c1024) with an adapter. However, since Needham's has been out of business for a few years now, and the PB-10 has been obsolete for even longer - finding the proper adapter might be a hard thing to do. I've found schematics to build an adapter intended for the Willem programmer - as well as pre-made versions on eBay. It seems like such an adapter _should_ work with any programmer. I just might have to add a manual switch on the highest address bit, and program a 27c160 in two passes.
So, basically, has anyone had any experience using the PB-10 with larger or 16 bit EPROMs? Anyone have the schematics of the official adapter? Anyone have an adapter or even another PB-10 to sell?
And what about the software? Is there any way to hack in extra device types?
Any help would be appreciated. Thanks!
