How about M65830 Looks like the top line can match that. It's a uC controlled delay IC.

Don't think it comes in a PDIP format. The one in your datasheet is closer to the size of the 6116 chip in the pic.

Yeah saw that, but i thought maybe a different manufacturier might

Been doing some more enhancing. Looks like Analog Devices logo on the right. Upper number ending in "JN". So far I see 75**JN, or 78**JN.

"Adult" themed hotel.. LOL

Yeah, you guys also have a Gram Parsons themed Hostel...

Wavely, do they have a nightly bon-fire and sing-a-long?

How about AD7569JN? Looks like the numbers would match the shapes, and it's 24 pin skinny package. Also, the datasheet states that it can be used with the 6116 for delay, and sample hold functions.

Yes, that looks like a very likely candidate. It also shows a 4040 to drive it. And as a bonus you could also use it to drive stepper motors!

digi2t · February 05, 2015, 01:24:10 PM

Yeah, saw that about the 4040. It could be one of the unmarked chips on the board.

The CD4040 is clearly marked in the picture on Page 1.

After some cognitive thought... I wonder if the Chip marked A2 (looks like it is IC7) might be a compander NE570? Thoughts??

Dang... I'm a dumbass. Thank you for that cognitive pointer.

Pretty expensive ic though

digi2t · February 07, 2015, 09:30:15 AM

I believe that the hidden 8 dip chip, hidden in the upper corner of the picture, might be a dual opamp. Looking at trace side pictures, the footprint looks like pin 7 going to an electro cap, and then connecting to a shielded cable out to the mix pot.

digi2t · February 14, 2015, 07:19:01 PM

Working on a deal right now, might have one on the bench soon.

Stay tuned folks......
