How was C128 not slapt together without any plan or adult supervision? You paid for 2 cpus and two graphic chips, one cpu only ran a reset routine?, and the second "graphic chip" had no graphic enhancements and required expensive monitor. Zero practical upgrades when running C64 software, no incentives to develop c128 native software. Price with floppy drive on par with Atari ST and 20% away from Amiga. As a bonus C128D was more expensive to manufacture than Amiga.
