Dave Johnson (WB4JTT) has documented how to adapt the DG5 emulator to be a SB-650 emulator: USING THE KV6O DG-5 EMULATOR IN HEATHKIT EQUIPMENT.PDF
I have created this page to capture build pics from others (send ’em in!), and to serve as a place to ask questions that hopefully Dave can answer. Until I adapt my SB-102, I really have no experience with this. But it sure looks like fun! Thanks Dave!
