[DECtec] [HECnet] RE: Slight OT: SIMH Framebuffer support

by e.olofsen＠xs4all.nl

Hi Mark and others trying QVSS support, Compiling a microvax2 with the QVSS display under Ubuntu on a laptop was successful. Booting an image for my VAXStation 3100 with device XQA0 was also successful and it was possible to login at the DECWindows login screen and the usual windows appeared - great!!! Unfortunately, the mouse does not work (moving and clicking), although with ctrl-right-shift the mouse releases. This is not really an issue with the QVSS display, and it could be because I used a VAXStation 3100 image; but should a mouse be configured in simh's initialization file?

Just last night I got code pieces from Matt Burke (the guy at 9track.net) to add VCB01 (QVSS) support to the simh codebase for the MicroVAX I and MicroVAX II simulators. I'm in the process of merging that code and adding the necessary build mechanisms to the makefile as we speak. This will be cleaned up and visible at https://github.com/simh/simh in at most a couple of days.... For folks who build their own binaries, the latest github code has a VAXStation I and VAXStation II with the MonoChrome QVSS video capabilities. sim> SET CPU MODEL=VAXSTATION enables the video subsystem. The VAXStation I has a limit of 4MB of RAM, the VAXStation II has a limit of 16MB. The makefile should just build the right thing if the development support for libSDL is installed on your platform. Please provide bug reports and/or other feedback with issues created at https://github.com/simh/simh/issues There is a glitch in my scripts which build and package the windows binaries which is failing to build the simulators with video support, so folks who count on the Windows Binaries will have to wait until I fix this.

Hello! Robert if I remember correctly, it was originally built to run first on a R.Pi device, and as a service on Windows? (That should be a statement not a question, but I'm surmising my way across this thread.) Actually my primary platform is Windows, so that is where it is tested most. I have also run it on the R.Pi but not that much to be honest. Others have played with it on various Unix flavours. Regards Rob

No. It has to be enabled on both sides. Easy to test. If I just turn off outgoing proxy on a VMS node, proxy access does not work on RSX for the incoming connection.

Seems like just failed access to me (unless the account actually have an empty password). Johnny
