content: In 20:36 in the video I noticed the hardrive was an IBM oem model DNES-309170 manufacturer January 2000 and I remember reading about them having high failure rates at around that time. I wonder if the software error had anything to do with that hard drive. Also I see date marks of 1996 and 1997 on the metal sheilding cover (that didn't have much underneath) so I wonder if that was some replacement drive.Not a Deskstar/Deathstar but according this:http://datacent.com/datarecovery/hdd/ibm/DNES-309170WQuoteThat model had overheating problems.

content: No wonder these machines were expensive. I would have expected far less technology, even in the 90s (there were some Media-Chips from Philips for Settop-Boxes that should have been able to provide a lot of the functions like OSD, video handling etc.) .

content: Now this was a proper teardown!Its truly amazing how much circuitry was used to do all of this. Just imagine the number of man hours taken to design all of it. I would imagine a modern ultrasound machine can do all of it on one pair of analog and digital boards and just send it into a standard PC.

content: Ha.. my job. I was an ATL service engineer. Know these systems intimately!This was a water damaged system by the looks of it.The 'filters' on the right at rear are two ferro-resonant isolation transformers, the big one for the system and the smaller one for peripherals. Pain in the arse to replace.ADAPTR handled Doppler mostly.Pretty much on the money for most of the description. :-)

content: Most of the hardware you see there is now done in software. Essentially a high-speed ADC feeding a PC now days (simplistically).The meaty engineering stuff has now passed into history for this application.The power requirements have dropped significantly, you can get a transducer terminated in a USB-C or micro-USB that plugs into a tablet and the Ultrasound is an app.https://www.philips.com.au/healthcare/sites/lumify

content: AMIS at 43:37 is AMI Semiconductor. They were bought out by ON Semi in 2008. I think that ASICs still make up a lot of ON's business.I interned for a small design group in Montana shortly after they were bought out that did custom dataconverter ASICs.
