Thing-a-ma-jig available As part of another deal, I acquired a piece of HP gear I have no interest in (nor do I know for sure what it is). It's an HP 30151A or "ATP Expansion Package". It appears to have 24 modems in it, or serial ports at the least (I haven't popped the cover). Pictures of the unit are at: http://www.ezwind.net/jwest/hp30151A Can someone elicudate what this is and what it's designed to connect to? If it's nothing I can use... it's available for shipping costs. Jay West

This is an external ATP port housing. It contains the RS232/422 ports which normally fit on the IO panel bays on HP 3000 Series 64, 68, 70, 58, 48, 44, 33 systems. They were also used as the IO panel bay for the HP 3000 Series 52, 42, 40, 30. There were cables which ran from the ATP cards to the chassis. Each panel could handle four DB25 RS232 modem style or eight (?) three pin ATP RS232 or 5 pin ATP (RS422?).
