I also don't remember this particular game but did play 13 Ghosts on the TRS-80. Both the TRS-80 and the COCO-64 were one of the few good memories I have about my high school experience. These two gadgets got me interested in programming, with BASIC and Assembly Language. I actually got the COCO, an external floppy as well as a cassette recorder for loading and saving the programs I'd experimented with. I had purchased the Editor Assembler cartridge for the COCO. Can't believe I lost that machine when I moved across the country :(
