I recently scored a Hewlett Packard 1670A Deep Memory Logic Analyzer and I finally had a chance to fire it up. This unit dates back to 1992 and is packed with all sorts of interesting options for connecting peripherals to it. One particular feature that caught my eye was the option to connect to an X Server.
Aside from the really cool stuff regarding X11, I'm absolutely fascinated by the user interface of this exotic piece of hardware. It's quite utilitarian, but still has an interesting sense of beauty and focus. I'd love to play with this (even though I have no idea what this equipment actually does).
