(Bob R. is now the lucky owner of this machine now. I was never going to find the time to repair the disk logic.)

This is my old but nice Data General Nova 4/X minicomputer. At the moment it contains the Nova 4 CPU, hardware floating point, a Model 6070 10 megabyte fixed/10 megabyte removable hard disk, Model 6023 800 bpi vacuum column tape drive, a D410 terminal, SLC-1 clock/calendar, TP2 line printer; I've got a second tape drive, and a DGDAC 4300 I/O chassis with D/A and a bunch of parallel. I've got software for it all, FORTRAN4, FORTRAN5.

(Here's a very technically sweet summary of Data General's history complete with tech specs, 'hello, world' and other code example, and many hyperlinks to DG stuff. Quite nice.)

Many, many thanks to Bruce Ray (of both Simulogics and WildHareComputers) for much help, advice and software, without which this thing wouldn't be running, and for saving it from the dump heap in the first place.

This page is just taking shape as I bring the machine up to operating condition. Here's a few tidbits with no better place to be just yet:
