"Dan Luu, in his blog, suggests that editing binaries is something that we should consider from time to time. From that blog:
Editing binaries is a trick that comes in handy a few times a year. You don't often need to, but when you do, there's no alternative. When I mention patching binaries, I get one of two reactions: complete shock or no reaction at all. As far as I can tell, this is because most people have one of these two models of the world:
- There exists source code. Compilers do something to source code to make it runnable. If you change the source code, different things happen.
- There exists a processor. The processor takes some bits and decodes them to make things happen. If you change the bits, different things happen.
If you have the first view, breaking out a hex editor to modify a program is the action of a deranged lunatic. If you have the second view, editing binaries is the most natural thing in the world. Why wouldn't you just edit the binary?"

You'd probably get a kick out of this

which is a 1802 programmed from a binary front panel
Or this

which is a 6502 programmed in hex.
I have both. Its hard to say which is better for new guy. The 1802 is certainly a simpler system but the binary coding is maddening. On the other hand 6502 is more complicated but the UI is far better. Probably better off with the KIM-1 6502 board.
I also owned one of these in the late 80s somewhat soon after it became obsolete but before it became a classic:

which is a 8080 programmed in octal, although you could upgrade it to a Z80 unfortunately still programmed in octal. It was an interesting experience.
Although if you feel the need for octal, this architecture is dramatically superior to the 8080:

And no I never owned one but fooled around extensively with emulation. They sell on ebay for about the price of a used car now in the 2010s.

Sir, thanks!, *this* is why I read SoylentNews.
Now where is my credit card, I'm gonna order a 1802 memship at once.
May the Forth be with you.

thanks for links... lead me to this http://www.brielcomputers.com/wordpress/?cat=18 [brielcomputers.com]
not a *real* altair, but would be just about worthy of programming while wearing a stormtrooper outfit
