I have most of this stuff in a box back in the office.
*> The GE software is "LogicMaster One" L1PC.bat (or LM Family L1FPC.bat)
*> Neither LM90 or VersaPro, or Proficy ME will work.
*> The audio port on the HHP is 1/8 inch jack, I have used a 3.5 MM.
*> You will need a "real good" audio grade tape, they are hard to find now that CDs have taken over, I used a micro cassette at one time.
*> You should 3 minutes or more to change the battery, but use good static protection and do make a backup first.
*> Only problem with these things is that when properly implemented they last so long that no one remembers how to use them when they do need attention.
*> I believe that there is a manual online either here or at
MrPLC.
*> There is software available to convert logic to GE 90-30 PLC also.
