[time-nuts] Synthesizers

[paul swed]

Joe
On the 3325 I will also bet they had to change a jumper next to each
socket. HP was quite good about that. I just did sort of teh same fix on my
HP54100d that simply forgot. Lucky for me after 3 years of hunting someone
finally put a good set on Diddiers site.
Regards
Paul.
