What is the exact error message? This should work fine on the Alpha, if it works fine on the x86 version of FreeBSD. The only real difference is the size of non-sized types (e.g. "long" and "pointer") and alignment. If it's an alignment error, it should be "automagically" fixed up (but the code will complain about it). As you say you're having a problem, it's probably an assumption about type size somewhere (I believe NetBSD and FreeBSD have a difference of option about the size of int or long -- I can't remember which -- John Baldwin would know, and so would Drew). > There are 3 available simulators: > KLH10 from Ken Harrenstein, this is a KL10B simulator that can run > tops10/20, its.

I might have to try this out myself (not that I'm really jonesing for TECO or anything. 8-)). Actually, I have a 9-Track tape containing code I originally wrote in college. Amongst other things, it has a DCL interpreter that I wrote in a combination of C and Harris H-800/H-1000/H-1200 assembly language. I really missed the DEC-20 when it was taken off line and retired. 8-). I'm guessing that people who are *really* into emulators could probably run the code "as is". 8-) 8-). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
