I'm finding two entirely different things with the numbers... I at least know for sure that TEC = Toshiba. The PC-TDLC would indicate a 'twinax data link control,' which would be a terminal emulator card... but the DEC-22V0 number seems to indicate a board related to the old Data East arcade games. I'd say it's more likely a terminal emulator rather than an arcade emulator.

What're the four chips at the bottom left corner, next to the EPROMs, and also, are there any labels on those LEDs along the rear bracket?

There are no markings next to the leds im afraid. The bracket has no markings whatsoever.
(update) they are numbered 0-7 (bit status?). The two red ones are marked P and S.

I have identified the main chip as an intel R80186. The 16mhz crystal next to it suggests it runs at a clockspeed of 8mhz. The chip has 1mb of adres space which seems to fit with my findings below.

The 4 chips in the bottom left next to the two socketed eproms are 256k static RAM chips.

is it from a point of sale system (epos)

My first thought was a cp/m card.

I have no idea what it is, but I know that I do love a full-length-ISA card! 😀

It'll be helpful if you can post the view of the bracket side of the card to see the type of connector on it. I believe the white cylinder is a... speaker?

boy that cap is really hanging off

Is there an FCC ID or anything on the back of the card?

I'd say it's a twinax terminal emulation card.

wtf is a terminal emulator?

Emulates a terminal that connects to old mainframes. Terminals were display and keyboard, any computing was done on the mainframe.

Does it emulate the whole terminal --> mainframe? (some typical brand ICL etc)
At my work we still use the same system we had in the 70's with Singer, ICL mainframes but it's now emulated in Windows...true server/clent software 😁

No, it makes use of the PC's monitor and keyboard, what's lacking to complete the emulation is done on the card and possibly some software.

The bracket just has a standard db-9 connector.
No FCC id code that I can see.

If anyone wants to take this card off my hands send me a PM.
