These things worth anything these days?

Those things do standalone QCII encode, don't they? I have an old Moden 10 or 50 that I've been meaning to hook up and play with.

Yes they do QCII format. They will interface into most Motorola mobile/base radios.

The 100 has talk delay time for the voice part of the page, sorta 'hands free'.

I have one of those old things in a junk box, the only thing i didn't like about them is that they would only do one group and it was hard programmed into the IC of the encoder. Mine was programmed for Motorola Group 2 so anything outside that group couldn't be done. Hence why you have to only enter 2 digits when you page.

You have the Moden 100. There is a look-alike version called the Moden 36 that further divided those tones into UPPER and LOWER for each tone group. I had a 3 UPPER Moden 36 that did half of the Group 3 tone block. The biggest problem with either the Moden 100 or Moden 36 is they aren't robust enough to handle most paging applications today. They were designed for self-dispatched fire and EMS agencies and very small businesses that only needed a handful of paging tones, and you almost needed to install them as part of a new system so you could coordinate all the paging tones into one group.

i have a few of those here as well

they also made an mdc console in that same package

My two bits worth:
The blank fusible PROM has not been available from Harris for the last 15 years or so.
I built a programmer from the Harris application notes, decoded the truth table for setting the programmer.
The MODAX 100 dial up terminal uses the same PROMS.
The MODEN 36 & 100 use random logic. This is pre micro processor technology.
An excellent mock up for learning basic TTL logic.
Counters, shift registers. BCD-7 segment decoder.
Audio synthesizer phase lock loop.
Big discrete parts, easy to understand.
I built the programmer because Motorola insisted that we purchase the entire 4 chip MODEN 100 prom kit to replace only one bad PROM. Many hundreds of dollars and we are a Motorola company shop.
I requested a spec sheet on the PROM, found that it is easy to program.
When parts discovered that it is possible to home brew code plugs the price came down.

Gotta love the DRNKEN BAT!
