And then there's my work in progress, an 1130 emulator based on a Parallax Propeller microcontroller...

The CPU emulation is about 3X faster than the original 1130. I use an SD card for the card deck (emulating a 2501) and for the printer (1403). The disk is emulated on a 2MB flash chip, and there are 8K words of core memory.
A modified electronic typewriter (via RS-232) acts as the console keyboard/printer. I apparently damaged one of the connectors a while back and have yet to figure out how to fix it. It's on my (ever growing) project list.
In the meantime, I wrote a quick-and-dirty console emulator program so that I can still play the games.

In 2007, Richard Stofer demonstrated his IBM1130 emulator as seen in the links at http://ibm1130.org/party.
Today, I ran across this blog post detailing how Mr. Carl Claunch is recreating the 1130 with a mixture of modern and old hardware.
Fascinating! Here's the link... http://ibm1130.blogspot.com/

Was the game written in Fortran? EMU or 1130? Assembler?

It was written in Fortran with a smidgen of Assembler. The Assembler code was used to bypass the Fortran character set restrictions... you couldn't directly print "!", "?:, or ":", even though they were available on the element.
The routine simply set up an XIO instruction with the appropriate console printer (rotate/shift) code. The resulting "operation complete" interrupt from the printing was simply ignored by the interrupt handler.

Somewhere around here I have a couple of the old BASIC games books popular in the late ‘70s. I recoded the Dave Ahl version of Lunar Lander to 1130 Fortran
It’s only about 6k but I don’t want to attach it to this email since not everyone will want it. Send me an email and I’ll return a copy
If you want Robert Louden’s 3D TTT, just ask. I’ll send that as well.
