Learning the Art of Electronics - LCD
The board consist of:


One sylabs c2 usb programmer (10$ chinese on ebay)
Dallas microcontroller programmer (2 to 5$ because it's a common USB-Serial adapter)
A very very slow 32ch logic analyser, cheap alternative - LED and resistors (5$), expensive but future proof alternative: Hantek LA5034 34 Channel 500MHz USB PC Based Digital Virtual Logic Analyzer (95$)


If you don't need all the channels you can also use a cheaper one with few channels as you pointed in the comment.
