The HP 150 does not accept ISA cards. It was from the era when top-tier vendors still thought they could sell PCs that were "better" than IBM's, and not fully compatible. (Even IBM made that mistake with the proprietary Mictochannel bus in most PS/2 models.)

There isn't such a thing as a "normal" PC-IB card. PC-IB is not the same as HP-IB/GP-IB/IEEE-488. PC-IB was only used for the short-lived 6101n series instruments. Both the instruments and the adapter cards are rare as hen's teeth.
