HA-89-3 Graphic & Sound Card
The HA-89-3 add-on board added color graphics and sound the any of the H-89 class of systems (H-88/H-89/Z-89/Z-90). The card was designed and marketed by New Orleans General Data Systems.
The HA-89-3 offers the same features as the HA-8-3, plus 3 counter timer channels and a priority interrupt controller. In addition to the optional Am9511A, it also offered an optional VORTRAX voice synthesis and 2 12-bit digital/analog converters.
Manual
Here is a copy of the HA-89-3 manual. Roy Jenevein, along with the other co-founders of NOGDS, have released their manual (minus the datasheets) to the public domain: "Except for the data sheets which remain copyrighted by their respective copyright holders, the manual is in the public domain and may be used for any legal purpose."
Actual Board
I received an HA-89-3 card and a photocopy of the manual, in the donation from P.R. Unfortunately, I do not have a diag/support disk for this card. I have not yet attempted to install the board in any of my H-89s.
