Hello, all.

I recently picked up a Micromainframe 5150, which came with the v4.0 driver that otherwise doesn't appear to be available online (?).

I'm using the unofficial v4.1 from Tvdog's Archive, which is based on a reverse-engineering and improvement of the official driver. The author of v4.1, however, mentioned his reverse-engineering was based on v3.2 & that he didn't have access to v4.0.

I'm therefore sharing the official v4.0 here in case anyone's interested. Preservation is important!

Note I've tested this on my Tandy 1000 TX, which has two such boards installed: a 5150 and a 5150t. Works fine.
