After going through a number of weeks of angst, which I must stress, was beautifully cured through tremendous help from Buffo and our mutual friend icemaker (thanks icemaker for suggesting the contact) I have reached a plateau of laser enlightenment or nirvana in terms of the ILDA projector standard. I wrongly assumed the 1999 standard that I downloaded for the ILDA web site years ago and still posted was something ILDA members and their products or compatible products sought to comply with.
If most people and products of the ILDA consortium are not following the 1999 laser color intensity standard by using differential balanced line drivers to the projector then it would follow the standard should reflect the industry accepted norms, or at the very least include accepted alternatives that are also part of the standard, including publishing this on the IDLA web site and in the PDF document.
My efforts related to taking my old Apple IIe single DAC card and blanking lines which was always used as a single-ended output solution to interface with the rest of the single-ended control consoles, AOM's and scan drivers, and building an ILDA projector interface. It also but my mind thinking about doing a similar thing to interface my later, more advanced time-based 4 channel DAC co-processor Apple IIe system with 32 programmable on/off control lines (named LaserMaster) to one or more ILDA projectors. I spent months designing and fabricated an ILDA interface board and mini-console based on the written standard. Fortunately, the circuit boards are still viable for the intended purpose with the unnecessary parts removed.
Now that I don't have to use balanced lines for color intensity my parts count went down from 79 to 44, a huge savings when applied to either DAC system I have from yore. I'm thrilled!
Icemaker, things are moving much faster now!
And thanks to the other forum members for their thoughts and ideas from my other posts. You are all a great bunch of guys.
