This is education at its finest. break the students down and you get the best in them.

Reminds me of my first computer: a Sinclair Spectrum using a Z-80, on the back connector of which you could plug a 32K (yes K) memory pack. You know something else? I don't think I ever managed to use all the 32K.....

I like this exercise of historical value, reminds me of early college days. Must applaud engineers that enjoy torturing themselves with this type of effort.

very cool article, I have a CRAY 3 ASIC encased in plastic on my desk and I have always wondered what it would it cost to do this today and now I know!

What a really neat idea! I love the concept of marrying the old with the new. It does show you how far we have come. In my earlier days, I designed an array processor that ran at a blazing 10MHz with 2 ALUs, a Multiplier, 4K words of program memory and 128K words of data memory. It sat in a 19in standard rack and used 1000+ amps at 5V. This was state of the art at the time and a very hot ticket for a few years. This would probably easily fit into a FPGA today with room to spare (and run much faster). I do like the "scale" model as well. Very nicely done.

One thing these recreations are useful for is to provide a way to run legacy code that was created for processors that no longer exist. Now my mind is buzzing with ideas for potential projects...
