Years ago, I stumbled across an article about emulating the PDP 11 computer. After doing a little more research I found a package of programs called SimH, which allowed you to emulate a number of computers. Amongst these was an emulator program for the PDP 11 system.
RSTS/E stands for Resource Sharing, Time Sharing, Extended and systems that ran it quite often had dial up connections. Our high school had several. The emulators I have found let you set up dial up connections using telnet.
I set up a simulation of the PDP 11/70 that I used in high school. I could not find a version of RSTS/E that was close to V06 that I used in high school so I installed one of the later version of RSTS/E, 9.2, I believe, and patched it with the y2K patch to fix dates. I ran that for years to play with occasionally.
I later found a version that was much closer, V7.0.07. This I installed and patched with a Y2K patch. Again I ran this version for years.
Since 2003 or 2004, I’ve been running these simulations, and one thing has been missing, the ability to print seamlessly, just like a real 11/70.
In this time, I have looked at another emulator, Ersatz 11, from time to time. It is a commercial emulator for businesses who need to retain their software, but replace their hardware. They allow hobbyist use for smaller configurations, and that works for me.
Last fall, I bought a Rosewill PCI communications card for my PC. It has two serial ports and one parallel port. I bought it to replace a usb serial adapter that I used to move files back and forth between my PC and either my Apple //c or my Macintosh SE.
Recently, I was reading through the documentation of Ersatz and realized, that printing was something it does. I decided to try it out. I started setting it up and added a little something extra.
I set it up to assign both serial ports as terminals. My apple //c is set up as KB1: and my Mac SE as KB2: using terminal emulation software on both machines. I also setup to assign lp0: to the windows printer using OSPRINT:.
