    You're referring to xtrs. I agree with you that it's great software. I maintain the Debian package for it and have made some minor contributions over the past 20+ years.

    I think the original Model Is all had a pound sterling symbol at 0x60 instead of the grave accent, which looks in this dump more like a closing (or "right-pointing" single quote).

    In my day I...

    It seems the fight to win the 16-bit war was so vicious that it ended up being won by a chip and an ISA that none of the manufacturers would have chosen. At least no one in the engineering...

    Dang. Now I want to get my 6000HD shipped to me here in Sydney so I can jump on that Fre8t-train.

    But this idea (of shipping it) fills me with terror.

    Thanks, I'll check that out. I'm sure I won't be able to love it totally--it's an Intel chip, it'll still be little-endian. :P

    Segmentation is a good idea, but you'd never ever guess it from the horrible implementation on the 8086, which failed to combine it with virtual memory, access protection, and a hardware MMU.

    Oh, that's interesting. I go way back and never managed to hear about that one. We need that diffed, disassembled, and commented somewhere.

    I can't think of any changes to xtrs's build system that either Tim or Alan have made. xtrs is very portable; its Makefile.local is only about 18 lines...
