It contains a bootable DDDP image with a SPACEWAR image binary image. Just grab the dddp.dsk image and use the TU58FS tool (or some other TU58 emulator) to serve it to your PDP-11. If you don't want to go down the route of assembling and linking all the source moddules there is an easy solution. I don't have a VT11 neither a GT40 so this is my best option to get SPACEWAR on a PDP-11.
In the end the program assembled and linked correctly.Īs a side note there exists at least two more ports of the SPACEWAR game to the PDP-11 architecture ( for example this one), but both of those rely on the VT11 vector drawing option which is for example present in the GT40 system. Finally during linking a number of issues with global symbols were found. Byte for byte were checked and yet more problems were found. Then the output listing files was compared side by side with the original scanned files. The files were then then fed into the PAL11-S assembler and numerous errors were detected already when trying to get the files pass the syntax check. Then I partly OCRed and manually transcribed all files into text files. With some help the original PDFs were tidied up to help the OCR process. The sources were provided to me as scanned documents. By luck I got in contact with Bill Seiler and he sent me the source files. Ufortunatley DECUS threw away all the sources many years ago. Actually this type of phosphor was used in the PDP-1 screen which the original SPACEWAR was run on.
Has a very nice P7 phosphor that has fantastic after-glow. It was then submitted to DECUS as 11-192. This port to the PDP-11 architecture was done by Bill Seiler & Larry Bryant in 1974. The original Spacewar! game was written for the PDP-1 minicomputer and there were several ports to other architectures.
