So I have 2 Trumpcard 500's and both say "This Device is not connected" when I boot off of version 1.3G of Trumpcard utilities. I've even tried 2.0? I think..or a later version. Same thing. The A500 has 2.04 ROMS. TC 500 is set to 1.2 kickstart, but changing to 1.3 didnt solve anything. Surely these two cant be bad? Very clean board inside also. Drive spins up and stays spinning.
set the trumpcard for 1.3 ,this is needed to autoboot. use 1.3 rom or up, preferrably 3.1. try hdtoolbox on it with the scsi device set correctly to the trumpcard device. i cant recall the name of it. if you can see the drive all is well. I have had the eprom go bad on mine so it may be what happened.
another test is have it all connected and jumper set to 1.3 and run sysinfo from floppy. look in devices and you should see the trumpcard device in the list,if not the eproms prob. gone.
