Northstar Horizon - them's fightin' words!

<cultural bias developed during the early years of CP/M compilers, which <often generated code blocks too large to be used in a N* with its BASIC RO <in place. There were some locally-generated business software packages What basic rom? The boot for the NS* and the memory mapped controller was only 2k though awkward at E800h orgin. the top 4k was available and quite usable. <The main issue for me, of course, was the compatibility issue, which, as <you've pointed out, could be dealt with by selective paring and pruning. Back then compatability was a generic issue. unless you were locked to only hardware do disk format (come to think of it, most of us were!). <Integrand, (Visalia, CA) which unified the drive and system packages, and <put whatever the currently "best" board set or assortment in it. That <usually meant CCS or SD Systems, at the time. Good stuff... but still thing like boot disks were generally locked to the disk controller used and often the serial IO used. CPM was supposed to fix that but being sparse in some areas people would go direct to the hardware and... incompatable... to say it was annoyance of the era would be an understatment. Allison
