My bad on the disk size. My memory gets worse and worse.

I eventually did buy TM100-2s for that machine and expanded it with a
Quadboard and bulk-purchased 4164s. A surplus B&W composite monitor served
for a bit before a Princeton RGB display replaced it. I wish I'd have saved
that machine. I haven't seen one with a lower serial number since.

IBM was pricey in the day, but they were competitive. You still pay nearly
$3K for cutting edge.

That was 160K for the DOS 1.00. 512 bytes per sector, 8 sectors per
track, 40 tracks, 1 side. (multiply) arguably (rarely done), you could
subtract 4.5K if you don't consider the DIRectory to be part of the disk
capacity.

You could have saved ~$400 by buying the same Tandon TM100-1 drive
after-market.
You could have saved ~$400 by buying 48K of the RAM aftermarket.
You could have saved ~$100 by buying the RF modulator aftermarket.
($1360 for bare computer + $300 for video card + $300 for disk controller
+ everything else aftermarket)


You could have paid more for CP/M-86 or UCSD P-system. (neither available
immediately, but in 6 months.)
IBM sold Easy-Writer (by John Draper) and VisiCalc.
