MicroMaster LV48 Eprom Programmer, anyone have any experience of these?

  1. Bassoonbloke
    Hi Folks,

    I have a Micromaster LV48 Eprom programmer from Ice Tech. It seems to have developed an issue !!
    If I either use the programmer on mains supply or batteries I get a Hardware error 121 on selftest. The programmer seems to work but is intermittent on testing.
    I've taken the thing apart and nothing is obviously going wrong (no burn ups or signs of caps going bad).
    The web gives no clue as to what these errors actually point to (memory test and oscillator test pass fine !).
    Does anyone have any experience of these programmers and if so, any idea what the hardware errors actually mean?

    Cheers for any info,
