Paul,
I would love it if you brought the programmer over. It'll be a week or two
before I can use it, if you don't mind me hanging into it for a bit..

I'm replacing a TMM2764D but, the mod I'm doing calls for a standard 16Kx8 EPROM
(27x128 chip).

Dragons are for avr though I suppose some of the hvpp modes are pretty
close to eproms.
It should also be a no brainer to build one.

We have a dragon programmer at OpenTechSpace that you are welcome to use any time. Scott has it.

I have an old Needham's EMP-21. It's USB, as modern as any eprom
programmer gets, and I definitely know where it is. I could bring it to
the meeting on Monday.
Here is the software. (Needhams went out of business, no website anymore)

You need to check if your chip is on the list, and if it is, which simm

I have an old programmer sitting around somewhere. If nobody else coughs up one that's ready to use, I'll dig around, dust it off (if I can find it...) and see if I can talk to it. It's almost certainly a serial interface, so as long as the protocol isn't too arcane, we should be able to make it work...

Wow. Bummer that mine is locked up in my storage unit and I'm in California. ;-)
In my experience, (parallel) Flash and EEPROM all follow the same
(JEDEC?) standard pinouts. In the olden days there were variations,
but "now" things are pretty standard. ("now" is in quotes because all
this stuff is obsolete!)

Hi, I'm looking to update the firmware on a synth that I have and I need to
program an eprom. I'm wondering if anyone here has an eprom programmer I could
use?
Also.. generally, would eeprom with the same memory organization and pinout
work in place of eprom?
Thanks,
Alex

Hey Dan,
I had a live chat (chat room support thingy on their site) with one of the
late night tech guys over at DigiKey, Matt I think. He was extremely
helpful and put virtually all the parts together for me. I think he even
installed Eagle on his personal laptop so that he could look at the various

If you are wanting really long range, check out the space chair project!
Simon faithful launched a weather balloon with a chair + camera attached to
it in 2004 and streamed the video for the audience back on earth.

I just read this:

and thought about this project. It seems like if you don't need
realtime transmission of the footage another approach would be to
build something that could withstand the fall and be easily

how about this one?
R2 100_NM R-EU_ R0805RND RESISTOR, European

a resistor with NM as units? I'm trying to put together the parts for
a Duemilanove, and working on the decoding of the eagle parts list.
Thanks.
