Eddy Yeung wrote the assembler for the Thor 21. The Thor 21 had a 68020 chip with floating point co-processer. After using this assembler for a while I detected an error in the FP instructions. I reported this and received a correction. Later on I discovered a second fault. I reported this too, but was told that Eddy had gone abroad to some exotic place (Cyprus?) and could not or would not make the necessary correction. I was also told that the source code could not be divulged. Later on I tried to use the Assembler Workbench but, even after hacking out the requirement to "load the original microdrive" before the program would start, I found it not too easy to use. Anyway, it does not cope with FP instructions or 68020+ instructions. It was that experience which led me to write GWASS, But only after taking a VERY BIG BREATH. I gave up using Workbench years ago but I might just have a copy somewhere - perhaps on a 5 1/4 inch floppy. I'll have a look and report back.
