Authentic Bits Programmer Pad (Z80) dated (c)1979 Bits, Inc.
This is a complete and unused pad, not just a single sheet -- an exceptional find for vintage computing collectors.
Originally used by early computer engineers to manually record memory maps, register states, and assembly instructions for the Zilog Z80 microprocessor, which powered systems like the TRS-80, ZX Spectrum, Kaypro, Osborne 1, and early arcade computers.
Each sheet includes:
Memory and register tracking layout for the Z80 architecture
Power status, flags, and instruction columns
Precision linework on archival-quality paper
Complete pad (unused, clean, and well preserved)
Printed in 1979 by Bits, Inc.
A true piece of computing history
Ideal for collectors, museums, retro tech displays, or vintage coding enthusiasts. Extremely scarce in this condition -- especially as a full, intact pad.
