ROMs Instead of manually flipping all the switches to load code into the Altair people installed ROM chips or only programmed a bootloader by hand which then would load the rest of the data from paper-tape, casette or disk. The Altair-Duino is based on an Altair 8800 emulator project published on hackster.io by David Hansel using the Arduino Due and Arduino Mega 2560, which you can, of course, replicate from scratch. The main goal was to be able to run the original image of MITS BASIC 4K 3.2 on it, which happens to work now. Sim-8800 emulates a MITS Altair 8800 on an Apple II. Thanks for answers.

Sure, there are other Altair 8800 clones out there, but all seemed out of reach for a simple working-man hobbyist. 3 years ago. I actually used an Altair 8800 when it was a current machine, and it blows my mind that this was done with two active packages, a few resistors, LED's, regulators and capacitors - about six 21'st century dollars of electronics (probably $1.50 1970's dollars).
