Off-Topic: EPROMs?
Hi, My apologies for this marginally topical post... I have an 8086 that I'd like to use for some embedded projects. One of these is the dream of many linux people: the toaster that runs linux. Hehe... 'telnet toaster'... Anyways, I have a bunch of EPROMs that I'd like to program, but I can't get the silly things to erase. They're supposed to be UV-erasable, but I don't have a good source of UV. I tried sunlight but apparently the ozone is too thick here. Can anyone suggest a source of UV suitable for erasing EPROMs, preferably without too much skin cancer :) Thanks, dstn. --- -- Dustin Lang, [EMAIL PROTECTED] -- (java developer, linux guy, green-haired freak) Why Linux is so cool: /usr/include/string.h:190: /* Sautee STRING briskly. */ extern char *strfry __P ((char *__string)); ---

Can anyone suggest a source of UV suitable for erasing EPROMs, preferably without too much skin cancer :) Firstly, check if they're UV erasable or electronically eraseable, when you're sure they're UV erasable, then try the following ideas.. make sure the UV filter is off before you try and erase it, even if there's a bit of pastic sticker there that looks clear, it may still be a UV filter. If you can, try an eprom eraser, they cost around A$100 or so, and will do the job properly. Failing that, find a good source of UV light, such as a UV light globe. These cost around about A$10 at an electronics shop, and fit into a standard light socket. As a last resort, try and find a tanning studio, and ask if you can stick your eproms in one of their tanning machines for a little bit, on ultra high. Davey
RE: Dynamically linked, modular Operating system
Al - I would be very interested in seeing your design for the dynamic linking mechanism for 8086 code for ELKS. Being very interested in compilers/linkers and operating system codefile formats, I would be willing to work on the linker mods that might be necessary to keep the linkage phase doable in one step. Does your dynamic linking support both automatic user-loadable modules? Properly done, I think this technology could go a long way to keeping ELKS small for those folks who don't have much memory, without going to the linux loadable module ideas that only work for the kernel. Greg I have been working on a mechanism for dynamic linking over the last couple of releases, and I even got a very simple test case working, beofre I rethought the design and came up with a better way. Seeing as there is interest I will try and commit my ideas to paper in a clear way so others can understand them before I make the next release, which should support it by then. The scheme does not involve modifying the compiler as such, but it does require a post link change to the binary, and a more complex binary loading process. Al
Re: Off-Topic: EPROMs?
You could buy a black light - I've been told that they are UV (someone verify?), or (and I don't reccomend this unless someone can verify it...) try microwaving it on a really low microwave setting.

I'm guessing that it's simply a dump of your vector table, in which case, you should be able to just write a little .com file, to create a file, and copy 0x400 from 0: into a file. If you want, I could send you a little .com file to do this (assuming that's what needs to be done). Davey

The UV blacklight bulbs you can buy are no good---the wavelength is too long. Get the data sheet for your EPROM, find the wavelength you need, then consult a lighting supplier. Build an enclosure for the tube, short-wave UV is Bad Stuff. DejaNews will probably turn up more info on homebuilt erasers. cjb. -- | Christopher J.

Off-Topic: How not to erase EPROMs
On Thu, 29 Apr 1999, vandegrift wrote: try microwaving it on a really low microwave setting. Oh, I don't think that would be a very good idea. Besides the fact that the wavelength is all wrong, you would probably zap the part. Stick with uv that is the correct wavelength. Mike P.S. Whoever mentioned the bit about the adhesive was right on the mark. It can really make erasing last a *lot* longer. Clean the adhesive off before you try to erase the EPROM.

Hi I have this "simple" question: what does 'linuxmt' means (is the directory where the includes are :D ). Why not something like linux-elks, elks or whatever. I'm just curious I think that it would be a good idea to design a logo for the project (something better than just the name). I think that it would be nice to play with the name ELKS, and the logo could be an elk, maybe playing with an penguin or something. I've found a nice elk or moose picture on the web but the problem is that I don't know its copyright policy (As far I remember is in http://www.arrakis.es/~juanjo96/sooseani.gif). Another other pictures with are somewhere in the oreilly pages (www.oreilly.com/oreilly/poweredby/). bye, Juanjo
Re: ELKS on HP200LX
Hi there !!! I found this information from the web some time ago: ---cut- MINIX on the HP200LX by Dr. Richard L. Dubs (last updated: July 1, 1998) Summary I have developed PCMCIA and BIOS INT13 Hard Disk Services for the HP200LX that allow someone to boot MINIX from a PCMCIA ATA flash disk. MINIX is not stable yet on the 200LX, allowing you (at most) to login and type one command before it crashes. Nevertheless, I believe that by solving the PCMCIA problem, I have solved one of the hard parts of getting MINIX to run on the HP200LX, and I'm hoping that the Internet community will now help finish the job. The PCMCIA and BIOS services I have developed should be just as useful to boot and run LINUX-86 (ELKS) on the 200LX. The software I have developed is provided on my web page (www.erols.com/rld) for download. - I hope this would be helpful !

I would guess microwave to be a *much* higher frequency range than light, I don't know. Much lower actually. Only x-rays and gamma rays have higher frequency than light. Doesn't necessarily mean microwaves couldn't erase an EPROM though - I've never heard one way or the other. It would probably cause some sparking on the pins too.

Can anyone suggest a source of UV suitable for erasing EPROMs, preferably without too much skin cancer :) You need a germicidal lamp (looks like a short fluorescent tube and also uses a ballast) and a light tight enclosure (the UV will damage your eyes). Do a Web search, there should be some circuits around. Sunlight will take weeks if not years.
