Any Data I/O 29B / PROMlink 6.10 / LogiPak experts out there?

Trying to get the ball rolling with my recently-aquired Data I/O 29B, I have PROMlink 6.10 working perfectly with the Unipak 2B, testing out operations with some TI 27C256s, but I'm having problems getting the LogicPak to cooperate. the Unipak 2B is loaded, I can verify devices, I can blank check, and it all works. Referencing the "using computer remote control" application note, when the LogicPak is loaded, I can manually send commands from page 4 like "HHHH @" to set the device family code (the right socket lights up), "[" to return the device family code, "B" for blank check (and it _can_ tell blank from non blank parts), and "T" for illegal bit test... However, as soon as I pick an in-app operation that goes out to the programmer, it spins a character-based "in progress" flag for 8-10 seconds while "setting up" the programmer, then I get a red dialog box that says... "Timeout ... ... while sending VERIFY PASSES to the programmer" and I can't get any operations initiated (blank check, load, etc). Does this ring any bells with anyone? I've never worked with logic devices and Data I/O hardware - we had an older programmer at Software Results, perhaps a Data I/O 19. I used to program 6309 PROMs and lots of 2764-27512-sized EPROMs on it from the console pad. I'm new to a) PROMlink, and b) the LogicPak. Also, if anyone has LogicPak firmware newer than 1992, that might be nice to play with, too. Thanks, -ethan
