Keep in mind that most programmers made in the last 25 years are microprocessor controlled, with their own firmware, so while you are at it, you might as well back those up too, but if it's your only programmer, you are stuck...

Then you are really looking fort some exotic programmers. Ironically, I bought a standalone programmer many many moons ago to back up a set of 1702's that I was concerned about. A few months ago, while cleaning out the lab, I found a paper listing of the contents of said UVEPROMs. Not quite sure where the programmer went to. :) On Oct 23, 2010, at 9:42 AM, Magnus Danielson <[email protected]> wrote: > Hi Chuck, > > On 10/23/2010 03:01 PM, Chuck Harris wrote: >> Hi Magnus, >> >> I keep an old Toshiba 1963 486 based laptop in good working condition >> to allow me to run my old ADVIN U84 DOS based programmer.
