Unfortunately the software isn&#8217;t recognizing the programmer nor is it able to identify which PIC has been inserted in it. Ah well, I think it&#8217;s a matter of parallel port settings, which I&#8217;ll mess with another night.<\/p>\n<p>Oh, and I had to etch two PCBs for it, because I screwed up the first one. I also learned what was most wrong with the <a href=\"https:\/\/nuxx.net\/blog\/wp-content\/uploads\/2026\/06\/sk1_midi_pcb_001.jpg\">PCB for the Casio SK-1 MIDI Modification which I screwed up<\/a>. I think I didn&#8217;t let the photoresist &#8216;develop&#8217; for long enough. I&#8217;ve found that with a fairly warm lye solution (the bottle had been soaking in hot tap water for half an hour) it takes about 1:30. With a room temp \/ cold solution after 12 minutes things still aren&#8217;t right. And when a contrast-y image appears, there is still some photoresist left in some points, which makes for an unclean etch.<\/p>\n<p>At least now I know. Now I can go to bed and stuff. Oh, but only after I wash the lead off of my hands.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tonight I made a parallel port PIC programmer from the MIDIbox PIC Burner schematic.
