I'm still in the process of reading and understanding the RQDX3 source code posted by Al but think I now understood most of it and I'm currently in the process of translating the source code into code for the microcontroller I have selected for my own MSCP controller. However there was one thing I'm not familiar with at all because which relates to the micro VAX. Not very important as I don't think I will have to translate this part as well but still I'm curious what it is and how it works.
In the module UQSSP.MAC of the source code there is a function call "map.buffer" with the following comment
does anyone know what this UQSSP specifications is and where it is described?

In the module UQSSP.MAC of the source code there is a function call "map.buffer" with the following comment
;
; this routine maps a virtual Q-bus address into a physical Q-bus address
; (this is only needed when the host is a microVAX I) -- we need the address
; of the current PKT to fetch the address of the map register table
;
; the UQSSP specification describes this in detail
;
does anyone know what this UQSSP specifications is and where it is described?
