NaBloPoMo – Digital Equipment Corporation VT-220

The VT-220 was a followup to the VT-100.  It had the same screen size (I think they are the same).  But it was way smaller.  The VT-220 was introduced in 1983.  What a difference 5 years made.  It also had a video out so you could hook it to your big screen tv I guess.  And some,  this one included,  had the 20ma interface option.  It also had a serial printer output.  On a DB9 (DE9 for you purists).  However this was a different pinout that IBM chose to use on the IBM-AT in 1984.  Also the LK-201 keyboard was introduced.  It had the function keys on top like modern keyboards.  It was perhaps the first to do so.  It interfaced to the VT-220 with a modular cord,  the same as a telephone handset but heavier gauge wire.  It was also used on the PRO 300 series,  some Vaxstations and the followups to the VT220.  I think the VT-220 defined what we think of as a terminal more so than the VT-100.

This sample was bought from the University of Kentucky and bounced around our lab for years afterwards.  It needs a good cleaning.


And we connected but then got disconnected.    Should I call tech support?

    I love how digital is in the name plate. Like digital was such a new thing it was a selling point. You don't see Apple pushing their Digital iPhone 3GS.

    If you can find DEC tech support, you have crossed over into an alternate universe. Let us know what else is different.

    These are some great pictures of the VT220. Would you be willing to license them under Creative Commons? I’d love to use one for a personal project (and give you full attribution of course).
