"Jim Pruitt" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Hello Mike and the group.
I have it from 2 reliable sources that U9003 was actually a mask programmed 74S387 which is a 256 x 4 bipolar prom. I have found circuits for a couple of readers. One is at http://www.geocities.com/SiliconValley/5857/progamr.htm but will only do the Signetics versions (82S126, 82S129, etc) which are available from Jameco but much more expensive than the 74S387. What I have not been able to find is what software to use with that hardware. N7OCS sells a dos program but I can not tell from his web page if that will only set up files for Syntor and MCX100 Motorola vhf radios or if it will read and program all the devices the programmer will work with. So if anyone knows where to get software that will work with the programmer I would be interested in knowing. I do know that there are many "universal programmers" in current production that read bipolar proms but most are in the $800 plus price range. There was one a pocket programmer that I ran across that is usb but is $250. It is or was very popular with the PIC group. I do not know if any of this information helps or not but I would also be interested in getting the hex file if anyone does happen to read one of the U9003 devices. Thank you.
