Here are the latest news about my HP-9835A. I have received and replaced the capacitors on the PSU and it did solve the strange sounds when booting. Now the machine boots fine with or without interfac

Does anybody has the user manual or knows the HP-IB command set for the HP-59313A Analog to digital converter ? I can’t find any copy on the net. The manual is on Ebay, but I thought I ask here first.

Blank as of nothing on screen or completely white (green) ? What I am getting is a white display. But I will check as soon as I have repaired my PSU. Envoyé de mon iPad

Hi, Here is a picture of my special effect rig for the movie I am doing. The motion control camera setup is driven by my HP-9920. It needs to control both axis motors, plus the projector focus and the

Effectively, I have sent most of my original 9845 blueprint scan to Ansgar a few years ago. It includes the 98770 monitor and its PSU. I also have the blueprints for the 98780 monitor but they are not

A few years ago, I tried to raise Ken Shirriff interest about the 9845C and specifically the 98770 monitor and its PSU, but it seems I was not successful ;-) What an fascinating article it would make

Hi Steve, Do you know if this ROM board (BASIC 2.0) would work in a HP-9920 ? If so, then I could be interested. Best Regards, François Envoyé de mon iPad

Hi Craig, Rik, Can you elaborate on how exactly you implement a 9895 on the HP85disk for use with the 98X5 computers ? What does the entry in the config file looks like ? I took a 9895 image file I am
