Interesting. Our current setup on this side of the room:

Nelson did the basic schematics and guided Adcom. I wrote the initial software and turned it over to someone at Adcom.
For the record, Wayne has done all of the preamp work for many years, giving me the leisure time to only work on power amps, sit on the beach and drink wine.

From googling around, I think the Phillips Ceibo DS-750 was the original:

That’s the one I had. I think one is on the way and I believe there is a Needhams at the factory. I will get one programmed.
I have successfully programmed a chip. Trying to find a working DOS machine took a bit of time.
there is a saying in my neck of wood, in fact more of a mocking of one saying the thing:
Moj majstore, lako je tebi kad znas i imas sa cim.....
literally translated to ZMEngrish:
My Meister, it easy for you when you know how and have all the Tools...
Unfortunately sometimes having a box doesn't mean it'll work. 🙂 A few months ago I was preparing a couple of old windows boxes (from early to mid 2000s) for recycling. They were fully operational before they went into storage but neither one booted up correctly.
That’s what I found, plus some dead power supplies. I finally found a win 98 machine that would boot up in DOS and had a working serial port for the old Ceibo programmer. It needed a PS2 keyboard because it lacked the usb drivers. Good brain memory exercise.
I recently gave away 8 early Windows/DOS laptops I used for years doing bat research (bioacoustics). As I was doing packing them up, I kept thinking - I need to keep one of these because something like this is going to come up. Did I? Of course not. Gave away dozens of 3.5" floppies, power supplies, docking stations. Just this week I had to buy a Win 7 laptop to use as a primary for my newly acquired Audio Precision SYS-2722, after giving away probably 3 of those over the years.
Hopefully my GFP-750 won't need a chip in the future!!! Yikes.

Wayne’s box arrived, I was scared, and nearly screwed the pooch removing the old chip which had been in its resting place since 2001. But I got it out and the new one in, and every function works like new. Volume is as precise as day one.
