RE: HP-IL IC?
Figured out more of the card requires external clocking and I found a pinout of the connector to the main board of the 5890. After providing a suitable clock the processor does run but the HP-IL chip is never selected so it looks like the 5890 needs to send a command to turn on the HP-IL.
