I was talking to Holger about the first PC he used was a Sinclair ZX81,
and I was thinking out loud that they sold a ZX80 PC too, and found out
that I remembered it correctly.

But You talking about the Z80 CPU in the C=128 brought a memory back to
me.

Rodney Zaks wrote a book called "How to program the Z80" {at} 1980.
I was in a Radio Shack store in 1984 and seen the book Marked Clearance
and bought it thinking I'd learn some about CPU's from my reading it.

I didn't, but I kept the book for reference.

RS priced the book at $10.95 USD.
