RasPi Powered ADM-3A Dumb Terminal

ADM3A

[Andrew Curtin] tipped us off to another excellent resurrected vintage one piece ADM-3A dumb terminal. [Andrew] not only resurrected this sexy machine by breathing life into her once more after 37 years but he also got it connected online to retro.hackaday.com for those coveted retro Super Nerd bonus points.

As with other ADM-3A terminals we have seen on Hackaday, the terminal screen can be interfaced over an RS-232 serial connector to a laptop, however, [Andrew] didn’t have a laptop to sacrifice so he utilized the now popular laptop stand-in RasPi. It’s a clever form factor solution which makes it appear more like a standalone computer for the first time in its life.

To make the hack work he needed a serial adapter to link the ADM-3A terminal to the Ras-PI so he constructed one for himself. It’s another clever solution but he didn’t share much information on this build. Maybe he’ll comment below or elaborate on his site with more details on the construction and utilization of the adapter board from the Ras-PI so others could easily repeat this fun hack.
