We should note that PC did not always mean IBM PC, the pet, the apple, the trs80, the Altair, are all PCs, just not IBM PCs.  


These systems came with 16 or 64K, and were expandable to 256K. I think it also used PC-DOS 1.0 supplied by MS, tho you could also get cp/m.  


These machines were grossly over priced compared to other offerings.

Yep, but this was the 'first' 'PC' as we understand it today. A collection of parts from different suppliers being packaged and assembled as a single computer. It was priced accordingly for an IBM product. It wasn't until the clone wars that prices came down.
