Computer's Projects
I have several computers Model HP9825A and HP9845B von Hewlett Packard. These computers are not a "home computer", but both were from the beginning a pioneering masterpiece of the Hewlett Packard company. Maintenance this computer in original state requires many spare parts. On the other hand, using original computer HP9825A and HP9845B is very difficult in these days. I have decided to completely convert one HP9825A and HP9845B into a new computers to be usable for many purposes of today. That is, a new CPU with memory, new power supply, etc.
On this website I publish from time to time result of my activity in this process. All schematic drawings and component locations on the circuit boards were created by me using EdwinXP CAE. The documents are available in PDF format and upon request in EdwinXP format. The ROM dump copies are available in binary format compressed to ZIP. On request are available in Intel or Motorola ROM format.
