When I worked for Litton Systems, we had FIDS (Flight Information Display System) machines running 486s with custom cases and hardware. Under the hood, though, it was just DOS 6.22 launching a program reading a one-way radio modem off a serial port. The expensive custom hardware was mostly about making it look expensive; I set up a terminal in my office just running commodity hardware. :)

pls preserve that chameleon thingy, it’ll be sad if it’s lost, even though we don’t have a use for it now

I'd prioritize the imaging of the drive, it doesn't sound entirely healthy.

The npn chip is the 512kb vram, not keyboard controller.

Note that the log says it's loading L3RouterX25.
It's also worthwhile knowing that X.25 isn't only used for terminals. It was used for checkout tills as well.
I also used systems that delivered internet over X.25.

The 8 Port ASYNC Card is a serial communication card.  The large port is for a corresponding cable specifically manufactured for it.  One end of the cable connected to the card then out of that connection were 8 wires leading to 8 corresponding 25 pin RS-232 connectors.  The 8 serial connections could have connected to modems or DSU's (BBS host or Dial-up Internet profider , serial dumb terminals, printers, industrial or laboratory equipment or a combination of things.
x.25 is a WAN protocol, used for networking over telephone company leased lines.  When compared to the 7 layer OSI model, x.25 implements layers 1,2 and 3: Physical, Data Link and Transport.  Once an x.25 connection to another system was established, the remaining network protocol stack was applied (IPX/SPX, TCP/IP, etc.)

80186 was used a lot in satellites afaik for a very long time, as they are quite resilient.

The 80186 was popular for embedded systems and industrial applications.

Cool. Gotta love antiquated technology!

Tekelec Chameleon?  Used to work at a software company that wrote software for testing telephone networks and exchanges amongst other things in the 80s!

The 3DFX Logo in the background.  Retro creds confirmed!

I spotted the 'Viewdata' string earlier in the vid and knew exactly where it was going! 😄

Quality video indeed, I really enjoyed watching this stream today. Keep-up on the content creation it's awesome!

Fascinating stuff cheers

Similar experience a while back , never know what's out in the wild

Looks like a terminal server/reverse telnet server, or a dial-in gateway.  Perhaps an X.25 "pad"  for local users or systems.
X.25 may be a product of the Seventies, but we were using it to carry our intraoffice I.P. traffic across the pond in the early Nineties.

I'd never heard of actual PCs using an 80186 before, but I did have an 80186-based caching hard disk controller.

Loved it, thanks for sharing

13:37 Erinnert mich an das AX.25 Protokoll von "Packet Radio" über CB Funk.
