microNovas are hind to find these days, unlike microVAXen or the "micro"PDP-11s. I have only ever seen two (both of which I owned at one point). They were both MP/100s - the 2nd flavor to come out - and was based around a Nova on a 40-pin chip. The previous version was simply called "microNova" and had a detachable control panel that looked an awful lot like a calculator of the day (1977 or so). The succeeding version, after the MP/100, was the MP/200 and used a much faster multichip processor. There was also a microNova/Dasher combination called the MPT/100 - probably DG's answer to DEC's PDT series. I am not sure when that came out. Cheesy little boxes, them microNovas. The interface to the drive was interesting, being a simple 16 conductor ribbon cable (obviously VERY serial!). If size is an issue, get yourself a real Nova, like a 4, or maybe an Eclipse. They are around, if you look long and hard for one. In fact, I am looking into buying a bunch of DG stuff, including a Nova clone(!). Anyway, they are not much bigger than microNovas.
