Northstar Horizon

I am not, nor have I been, trying to get a Horizon, or any other model of N* going. I recently arranged to give away my last bit of N* hardware, a Z80A CPU card. I have had lots of trouble finding people who would take it. The problem, of course, isn't that they don't work, because they do, and very well, too, but rather that the N* environment is so limited, particularly in the Horizon with its 8K ROM space, that many compiled programs won't work because the TPA is too small. What's more, the FDC isn't capable using of CP/M-standard (IBM-3740, SSSD 8") diskettes. They're OK as a curiosity, but back in the lat '70's and early '80's, they were not well received because of the TPA and FDC issues mentioned above, and I warn everyone off them due to their resulting limitations. regards, Dick -----Original Message----- From: JusmeSJ(a)aol.com <JusmeSJ(a)aol.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Saturday, October 30, 1999 10:30 PM Subject: Northstar Horizon i/o,
