after quite some time, i reached an important milestone with hp9k_3xx in mame: booting HP-UX!
It's only HP-UX 7, but at least a start. The goal is to get HP-UX 9 running, but have to fix some unsupported MMU stuff for that.
There are also a few things (bugs!) left:
- BASIC/PASCAL doesn't work if the DMA controller is present
- The RTC doesn't seem to work in HP-UX 7 - or is it only Y2K, as HP-UX 7 isn't Y2K compliant?
- other stuff that needs to be cleaned up before submitting, namely my HP DIO implementation, the DMA controller, and the MB87030 SCSI controller
Here are a few pictures:
