But Sun designed real workstations, unlike the original PC which was assembled in a hurry from catalogue parts and with some choices already totally stupid, such as default text only, 8088 cpu, poor card sockets like Apple II and S100 instead of indirect connectors, no battery backed HW clock, and impossible to ever have more than 640K without holes in the memory map. Compare the Victor 9000 /ACT Sirius 1 designed by Chuck Peddle which was on sale in UK & Ireland before the IBM PC.
I never saw a Sun in real life

I did use the Sirius 1 in two jobs. Big difference too between Apple II 100k floppy, much better IBM and other 160k floppy. The Sirius varied floppy speed to fit 2.4 M when 8" drives 1M and PC 160K or 320 k.
