From their web site, "...Captek/Science Products has a 50-year history of adapting an extensive array of items for use by the vision impaired. Our focus has always been on innovation, quality, and service. In recent years our specialty has become voice adaptation of digital displays, but we continue to investigate other creative ways to make equipment accessible through touch and sound." end quote.

They've a small enterprise that's been going for 50+ years, but it looks like they've had to scale back their business in recent years due to declining sales.

I'm sure they'd appreciate knowing you've managed to recover a piece of their history to working condition.

Some interesting reading on their history here:

Thanks for that find, I tried - couldn’t pull it off….

I dropped them a note as you suggest, let’s see if they respond

UPDATE

They responded!

It appears to be on of the first units they converted - it is from before they started tracking Serial#s

I took the chance to ask a couple of questions which might be interesting for the forum, I'll come back if /when I get a response - let's see

UPDATE

Mike responded, he said that they had made 50-100 of these and also the TI-66 (apparently that was their first model to mod)

He could not recall the exact price but suggested 5-600 dollars a pop, so not far from the 1000 (incl the 15c) that I had expected.

When I have the courage, I may take it apart completely to see where the device gets the display data, nothing obvious comes to mind - suggestions are welcome.

It has to come from the display somehow as it reads only what the display says, four-point-zero-zero-zero-zero in FIX 4 less in FIX 2

I can hear the NUT-CPU running when it is. The readout can only be done after the CPU goes into idle - I can hear the CPU working when I turn up the loudspeaker (it would not pass todays EMI)
