Hey folks-- through some of my own projects, I've ended up with equipment that can dump and program the elusive 1702/1702A EPROMs as well as 2704/2708/2716 etc. I know this need comes up occasionally in the 1970s computing stuff, and not everyone wants to DIY or scavenge a programmer. Since I have the equipment around anyway I decided to hang a web shingle to offer the world's most incredibly niche hobbyist service to other vintage computing people. If you need to work with 1702As (etc) and I can be of assistance let me know, here's the page!

Welcome to VCFED.

This looks to be a handy adventure - not that I have a requirement at the moment though.

Can I suggest adding your location to your profile though? I guess you are in the States somewhere (as your prices are in dollars).

Done, thanks Dave. I am indeed in the States-- I'm more than happy to help out anyone outside the US, but the US international outbound postage has gotten almost prohibitively expensive so it may or may not make sense. Anyway, hope this will be useful for someone at some point.

Hi
I'm always looking for code used by the Intel SIM4 setups. I'm looking for the A0542 EPROM that has the correct timing for the 1702 ( non-A ) EPROMs. I'm also looking for the ROM set A0750-A0758 ( The ROM simulator ). If you find 1702A with these labels please don't erase them.
I do have A0540,A0541 and A0543. I also have the assembler, A0740-A0743.
I have a setup to program 1702As but it is flaky right now and I've not had time to analyze the failure.
I have a large box of 1702As that were pulls. Most with bent or broken pins. If anyone needs a few 1702As for a project let me know. If 4 or 5, I'll send them for shipping cost. If the pins are broken, they can be easily piggy backed by soldering a pin from a sacrificed chip.
I don't have any white Intel chips in the box( nothing collectible ). These are mostly second source vendors but do have a few Intel purple packages.
