A friend of mine has a dozen or so NOS DataMetrics 1500 high-speed thermal printers. Even being from 1990 or 1991, they only have two or three ICs and the rest are transistors...100's of TO-5 transistors on cards which are used to drive the nichrome wire printhead.

wot an amazing piece of technology, i can imagine these things to be still useful today, as an analogue video (but digital in capture) based unit it would have so many cool applications, the amount of cool old school visual effects that could be generated using this thing is endless.. something that seems lost in todays world of cheap consumer electronic rubbish.. im glad u put it back together, i was worried that like so many tear down videos on youtube, things just get junked afterwards :-)

That makes sense, yes. The highest PCB revision I saw printed in copper was J, but many of them had only handwritten revisions that I could see. Still, that's a lot of changes going through a full release process!

Electronics sure has come a long way in 20 years.

Great video! It's been an unusually awesome week for teardowns

Re. the combining of data from the ADC and that other board - there was an option for this system for external inputs to be recorded alongside the video data - e.g. sensors - I wonder if that's what it's for.

As the AE rev is hand-written it probably includes build and PLD revs, not 26 PCB revs!

Thinking about it maybe they were mostly in the imager. I found a ZNA134 datasheet fairly easily via Google BTW.,

Even though they have the empty chip places, they still populated the decoupling caps, which is kind of interesting. :-)

Empty chip places are for potential mods or bodges

All that memory bus interleave in there would explain the need for two 68000 processors...

In the processor itself? I guess they designed most of them out, I only saw 2 Plessy chips in the processor, the sidebrazed cerdip video timing generator and another unidentifiable one near the composite video outputs.

My Ektapro TR was full of Plessey MOH chips - suspect they are custom/semicustom

That's basically DRAM in RAID 0

Yeeesss... I understand some of these words.

Great video! I was thinking if it would be possible to upgrade it with modern memory to increase the record time.? Anyway.- I think this system will be a 5 chip solution these days..?
