Christian,
You should try the service manuals of the HP 1000F series interface cards.
You need the service manual of the HP-IB cards.

I'm trying to repair a HP260/30 which fails self-test at step
9 (HP-IB Programmed I/O test). It seems that the HP-IB
interface card is the cause.
There's a 1TL1-0001 HP-IB controller IC and I'd like to know
if it could be replaced with a 1TL1-0006. The other ICs are
all standard TTL (apart from the 74F403 FIFO memories and the
HP-IB bus drivers).
I know I've seen a pinout of the 1TL1 IC somewhere, but can't
remember where...
