My Mark-8 reconstruction, built 25 years after the original Radio-Electronics article:
The PCBs are new, the ICs and other components are as close to the correct age as possible.  The switch PCB is my design; the original switches were hand-wired.

Tools

My 8008 Interactive Assembler for Windows (570KB)  (sample program)
updated 7/29/2002 - V1.12 - added hex file output, new directives (BSS, DATA, CODE) and new opcode LHLI
updated 10/31/2002 - V1.15 - added file backup and fixed some display bugs

8008 Inverse Assembler for HP Logic Analyzers  Simple, but it works (screen shot).  As few as 12 connections to the CPU and you can see what instructions are being executed.  There are two versions; one demultiplexes the 8008 address bus  itself, and one uses the latched address present in most designs and has a bit more flexibility in clocking and tracing.  Source code included.

Hardware

The switch printed circuit board.   I mounted the switches on a printed circuit board for a cleaner appearance and a better mechanical mounting, since I didn't want to mount my Mark-8 inside a cabinet.
The Mark-8 prototyping board.  I laid out this board in order to have a clean way to add some memory and I/O to my Mark-8.  It is intended to replace the existing memory board, but could also co-exist with it.
