As I was looking through my old CP/M files earlier when I found this I couldn’t resist converting it to something a little more old fashioned.
I was looking through some of my old CP/M files (running on a virtual ALTAIR Z80 using simh) when I can across this old FORTRAN IV program.
I first encountered VMS sometime in the 1980’s after having used an ICL1900 and a DEC System 20 and I’ve been a bit of a fan ever since, particularly of the file system which supports file versioning, which is something … Continue reading
I have two network interfaces in my workstation and I wanted to dedicate one to a separate network to use with my real and simulated MicroVAXs. The first problem was how to bring the second interface up without giving it … Continue reading
While sorting through some old FORTRAN notes I found what amounted to a one line program, which was included as a minimalistic example of what could be achieved using implicit DO loops.
Obviously UFW does not affect network protocols like DECnet or LAT but to allow incoming TCP/IP connections to a tap/tun interface that is being used by SIMH or QEMU you need to modify the firewall rules.
I’ve known about this website for a while but although the author had made some (considerable) progress enhancing the VAX simulations in ‘simh‘ until a few months ago there was no code available to run on Linux.
I use the SIMH simulator to allow me to run VAX/VMS on my linux desktop using an OpenVMS Hobbyist license. Compiling simh and getting a simulated MicroVAX II running on my Raspberry Pi was relatively easy.
I have not had much time to post any updates lately – largely because I’ve been so thoroughly distracted by some new old technology.
