Commodore released the PC1 in the mid 80’s. It featured a 4.77 mHz Intel 8088 processor. (Note that they included the decimals in the clock speed!. It’s not 4. It’s not 5. It is 4.77.
It was mounted with 512kb of memory and a 5,25″ floppy disk (360kb on each side) and was delivered with a MSDos 3.1 boot disk, which also had Microsoft’s own version of Basic, GWBasic.
