content: Not sure where to put this, but if it needs moving someone will.Ok so the question is. What test gear have you got and what is it's eprom size(s). Why do I ask, because I think I might like to collect hex files of equipment and the dates etc etc on their labels.

content: You can archive all eeprom based testgear for a few cents a year on s3. And it is a noble goal I fully support. Nvram too.

content: KO4BB has a lot of ROM images for different equipment. Have you checked it? The most common one I have seen are are 128 kbits and 256 kbits.

content: Older equipment that ran with a Z80, 6502, 6800 or other 8 bit micros often used a 2716 or 2732 eprom, so the files would be only 2 or 4k in size.Still have a pile of them around, probably all still work and might still have readable data on them. Those stored though in the UV light box probably are pretty well wiped by now though. they probably had around 30 hours of UV applied to them over time.

content: I didn't spot your reply till just now jwm_ so apologies for not replying. I have been to KOBB site, and I want to have as many copies of as many eproms etc etc as is possible. Primarily older gear as it decays and dies of the internet.Anyone who wants to send me such roms please do. just send a copy of any label on the rom and what it is out of.

content: Main problem is that reading ROMs ain't always quick and easy, and lot of people who have gear, usually may not want risk damaging gear (as may need desolder ROMs etc) or simply don't have programming hardware.Second problem is collecting files is one thing, but providing them to public and making it searchable and accessible is different story. That's even more important, than storing them. Also it takes time to catalog them and sort, leave alone testing if they are valid.Having all that said, is it worthless? By no means, but be ready for way more work and time on this, if you serious about it, than "give me files, i'll store them". Size is non issue here, but your time and commitment is, believe me.P.s. I do have unlimited storage and public site dedicated exclusively for T&M gear firmwares, files, documents and notes, you can join if you seriously into this

content: Hi TiN.Sorry if this comes over as combative it is not meant to be, sadly being ill lately has made me rather ( insert correct wording as I have forgotten it ) and I keep falling asleep on my PC.I have no concerns about being able to serve things up to people. My problem is, and here I go on a rant that will annoy some people but tough, is that I have no time for selling things I get for free, there are those who are given such things in goodwill with the belief that they will be made available to all who need them for free and then suddenly after getting given it decide that it is only right they make money out of it as it costs them money for a hosting service and time etc. they did not say that when asking for these thing for free from those who gave originally and in the spirit of why it was given. I am not saying you have, would, did or ever would do such, I am merely explaining how I feel on it all. Hell if I had my way I would send the damned things programmed on receipt of a SAE and blank rom chips. I guess that would never happen. I suppose I lived on the dark side of efnet etc too long.I can and have had my own searchable database before when I used to collect coins and PC games so that is not a problem. I am only interested in T&M roms, not other sorts. and yes I understand many would not want or be able to read theirs for fear of breaking something. So I will just have to wait and see what comes. If I could stay awake more than ten minutes a day to achieve something it might help !.
