I picked up a Heathkit Microcomputer Learning System, Model ET-3400 at
Goodwill yesterday. It has hex keys for entering data, and LED readouts,
plus some you can blink. It's all laid out and labeled, with a breadboard so
you can jumper the parts together.

Oh yeah, in searching for info on it, it appears they still sell an
ET-3400A, and I found an emulator for Windows that shows the LED's and keys
on screen.
Here's some info from the readme:

TRAINER Version 1.1
(C) Copyright 1996-1999, Bill Lovegrove

This program is a software simulation of the Heathkit Model ET3400
microprocessor trainer. It implements the full 6800 instruction
set, and allows the user to practice writing 6800 programs.
The ET3400 keypad and display are accurately simulated.
