Commodore 1520 Plotter

Some time ago I suggested some possible updating of Page 1 of this newsletter. Having had a Commodore 1520 plotter for a few years plus John McMichael’s programming and interface (Oliger) but not having actually done any programming for it, now seemed to be a time to get at it and see what I had. Page 1 shows the results of the plotting for the graph, making it similar in size to the old TS 1000/2040 print and the more recent 2068/Epson printer output
