Ok? thanks,
I got the user/service manual, it's handy when fixing the thing.
I'll try it out when I'm going to play with the multi-programmer.

And now something completely different......(free after

Did you ever use the HP 59401A HP-IB analyzer ?
Yes, I have one, and have a fair idea how it works.
The lower PCB is the PSU (the +5V switching regulator is
somewhat odd), the data capture RAM and data path circuits
The upper PCB contains 2 seaprate sections. The display
driver in the front left corner and the main control state
machine, based round those 4 ROM chips in the middle.
I can provide a _lot_ more info on it if you need it.

It's fun to look at the HP-IB(us) the display
flickers
nice, but is =
there realy meaning full use for these analyzers
?
It's not very useful for mass stroage devices (it can't hold
enough data, and if you single-step it, the host connected to
said mass storage device generally times out and gives an
error). But I've found it very useful for examping data
to/from HPIB instruments, and for testing HPIB interfaces,
printers, etc.
