Altair 8800 reproduction

I thought about it long and hard. A fully configured Altair 8800c would be
at least $1200 plus shipping to Australia from all the different component
suppliers at least another $600. I would end up with a "real" system but
some parts wouldn't quite be real. For example the floppy drives are
emulated via a USB cable and a server running on a PC. It would be possible
to add real 8" or 5 1/4" drives plus power supplies plus cases and cabling
at great additional cost. At the end it would still be some hybrid system
with some modern bits substituting the original components. I would have a
nice S-100 bus system but it wouldn't be an authentic Altair 8800a. So I
decided to go down the fully emulated path and looked at Mike Douglas's
Altair 8800 clone and the Altair-Duino.

I ended up buying the Altair-Duino a very promising Arduino Due (ARM)
based clone similar to Mike Douglas's clone but without the nice metal case.
This Altair-Duino kit is affordable, is open source and has a powerful
hardware platform.  Now that I am retired I am time rich and money poor.

The "Standard" kit is $149.95:

Strangely the website says there is no stock available from the guy
himself, but Tindie has 4 in stock:

I can't wait for it to arrive. It is a long way from Minnesota to Western
Australia. Covid-19 doesn't speed it up either.    :-(
