Period pricing references (was Re: Micro$oft Biz'droid Lusers)

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. Erik S.

(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.
