Yes, finding new 1Mx8 EPROMs is not difficult but that isn't what I am asking about. They only cost about $10 new and are an excellent value, IMO. However, I am trying to find some low cost *used* EPROM parts to help out some homebrew SBC builders. The N8VEM SBC homebrew computer I designed uses the 27C080 or 27C801 for its boot device/block device/ROM drive. I'd like to keep the costs as low as possible and am trying to keep the EPROM at or below $5 each. OTPs are an option but they are less desireable than the reuseable parts with UV windows. As it turns out, most of the people requesting the PCB for building their own homebrew computer are also requesting the EPROM. It rather surprised me as I thought more people would have their own EPROM programmers and erasers. I have a limited quantity of the 1Mx8 EPROMs on hand but not very many. At the rate they are going out with the PCBs, I will exhaust my stock quickly -- long before I run out of PCBs. In retrospect, that is probably bad planning on my part this is an amateur project and I am not a professional businessman. I found a few more 1Mx8 EPROMs on eBay but that doesn't really solve the problem. What I need is the 1Mx8 EPROM equivalent to this website: http://epromman.com/ I have purchased bulk used EPROMs from "Mr. EPROMMAN" before and they are an excellent value. Unfortunately, he doesn't carry the 1Mx8 parts. :-/ Thanks in advance if anyone can help. Andrew Lynch
