I think all these old machines were impressive.
Most of the board layouts were by hand, there are no programmable devices on most machines for several years, slow parts make timing even more critical, parts were expensive so you tried to maximize the use of the gates on your chips which makes board layout even more difficult, and most of the software/firmware was developed with limited development tools.
Now you draw the board layout on screen, the software can auto-route a board in a couple minutes (though it usually needs tweaking), you can program large portions of a circuit into programmable devices, parts are cheap, and you have cross development tools capable of building and programming a ROM with little effort. You can literally do in hours what used to take days or weeks.
I totally agree! I am amazed of the things they did back in the 60's and 70's with the early computers.
