From that link, ILLIAC Suite / String Quartet No. 4 is a 1957 composition by
the ILLIAC I, programmed by Lejaren A. Hi
I'm not looking forward to trying to reverse-engineer 48-bit and 56-bit ECC
polynomials. However, they usually tried to choose polynomials with
relatively few terms, to minimize the number of XOR gates needed in the
hardware.
The common "Glover" 32-bit polynomial was:
x^32 + x^28 + x^26 + x^19

I took the thing apart last night. There is no room for an internal disk
drive.
I'll take photo's and post them by the weekend.
Overall the computer side is mostly a typical 9000/200/300 chassis.

As an aside, didn't the much later Radio Shack mouse for the CoCo work like

9.3V might actually work fine for a TMS9980, even though it's below spec.
It's not going to damage the part, so it may be worth a try before
modifying the board for 12V to the CPU socket.
In NMOS digital parts that predate depletion loads, Vdd needs to be
significantly higher than the most positiv
