At the time I was only interested in the Apple II, DEC PDP-10, and BSD 4.x on VAX, so I didn't pay much attention to his system. I had problems similar to what you describe when I was bringing up the PACE version of fig-Forth, and tracked down and fixed a serious bug in the published listing. AFAICT, I am the only person other than the author who ever ran the PACE version. I found it far easier to debug on a simulator rather than the real hardware. The 6800 version must surely have been far more popular than the PACE version, so it seems somewhat unlikely that there would be a huge defect in the published listing, but it's not impossible. I wrote some 68HC11 assembly professionally in the late 1980s, but the only actual 6800 code I've writen was a 6800 version of the Apple I monitor. Writing 6800 code after being used to the 68HC11 and 6809 was a huge step backward; I kept trying to use newer instructions and addressing modes that the 6800 did not have. I have a non-working Electronic Product Associates Micro 68; maybe someday I'll fix it up. Eric N2ES
