EPROM programmer and eraser

[Stephen Early]

People looking in the top of the Stratasys last night sounded interested when I mentioned I had an EPROM programmer and ultraviolet eraser knocking around at home.  Is there any interest in these finding a new home in the hackspace?  The programmer has a serial interface and can program chips from 2716 to 27512 (instruction manual here).  The eraser is a small ultra-violet light box.

If it can program this chip :

4k-Bit 1-Wire EEPROM

Then I would be very interested.

An older eprom programmer of the type used for UV-erasable eproms
probably won't handle that (though some of the more flexible ones,
like the Dataman might).

It's more easily done with a bus pirate, or with the 1-wire library on
an arduino.

The one I was posting about can't, but I do actually have a couple of 1-wire interfaces (one serial, one USB) that will.  I'll try to bring them in next time I'm around.

Kal,

I'm sure that you could temporarily plug that into an Arduino and write to it.

Someone out there has surely been there and done that.

Try here  http://code.google.com/p/gfb/source/browse/arduino/?r=65

Looks like someone has written a 1-wire library for the DS2433

I have a bus pirate BTW if you need to try one.

I'm probably at the space tomorrow afternoon/evening

I am borrowing the one in the space and have got as far as reading the
8bit unique ROM address but not figured out how to use the bus pirate
to read or write to the actual memory...

If you are around I could use some input. Could you email me roughly
when you are near the space tomorrow as I'll be nearby? Thanks
