- And why did the market choose otherwise.
-
- Easy. Dos 1.0 - on a 64k max memory machine with a single 160k floppy
- at $60 list price was a much better deal than CPM from DRI at $300.
-
- DOS 1.0 looked a lot like CPM. But when I used it I found that the
- S-100 4Mhz Z80 based machines with memory mapped display was so much
- faster than the 4.7 Mhz 8086 machine with the IBM 'idea' of a video
- display adapter was pretty poor.
-
- The machines were pretty evenly matched, but the slow display on the PC
- made it look slow.
-
- I remember one demo I saw of a computer called a Max80 by Lobo. It was
- CPM or Radio Shack Model I hardware compatible.
-
- They'd fire up a program writing numbers to a screen on the PC, and
- then walk across the room, type in the program on the Max, and then run
- it, and have the Max finish first. Impressive to people who didn't
- know a damn thing about computers.
-
- And when DOS 1.0 came out the Xenix wasn't even talked about for low
- end machines. I remember seeing the first effort by SCO at one of
- their very first public outings. I believe it was at Comdex in 1984.
-
- The *IX variants up to that time had a real problem running on an 8086
- chip. I wouldn't say it was slow, but the only other computer that I
- saw that was slower was turned off.
-
- Microsoft's Xenix efforts were for Tandy on their 68000
- based machines. That was the 1.x series. The 3.x series for those
- machines was done by SCO. The IBM Xenix 1.0 was released unsupported.
- The 2.0 was really bad - supported - but bad.
