Nomadness: Maudlin Front Panel Retrospective
There were 8 interrupt channels, 64 bits each of input and output, a graphics subsystem using a pair of 8-bit multiplying DACs outputting X-Y to my Tek 7504 oscilloscope from a DMA display list, and a painfully slow math co-processor made from a Taylor-Series calculator chip with kluged BCD and 7-segment interface (mostly because I was intimidated by writing floating-point routines). I remember the night it drew a lovely (sin X)/X curve… took HOURS and I had consumed half a bottle of Jack Daniels by the time it was done, but it was a thing of beauty, I tellya what.
