Remapping the HP150 keyboard

   [HP59401 HPIB
analyser]

  I got the user/service manual, it's handy
when fixing the thing.  
 Does this manual have any detailed information (ROM dumps, 
 state diagrams, etc) on the operation of the various state 
 machines in the instrument. It's the only bit I've not 
 seriously tried to understand yet.  
 I'll have the ROM listings, if you want a scan let me know. 
 No state machines, except a overview diagram. 
That could be useful... If you have time to scan it sometime (no hurry, 
my 59401 is working perfectly at the momnet), please send any scans to 
tony_duell at yahoo.co.uk, and not here.

Thanks in advance for any help.

  For doing quick tests on HPIB stuff like that, I
find the 
 handiest thing to used is an HP71B + HPIL interface + HP82169 
 HPIL-HPIB translator.   
 Why this combination and not a HP 9816 or other basic machine with HP-IB ? 
It's a lot smaller for one thing (read : I can noramlly find space for a 
71B on the bench, fiding space for a 9816 + disk drive is a bit harder!). 
It has BASIC in ROM, I don't need to boot it from disk. And the HPIB 
interface is not shared with the boot device, which means that whatever 
the device-under-test is doing, it's not going to prevent the machine 
...
 from booting, or worse still corrupt the boot disk.

Yes, I _could_ configure my 9816 with ROM BASIC and/or a 98624 HPIB card 
and avoid those problems, (I have both of those PCBs), but it still 
wouldn't make space for it on the bench.
