In 1986 I was developing on a 68010-based SYS V machine for Morrow Designs which had a whopping 1MB of RAM. This was considered to be a very well endowed machine! It was packed with all kinds of controller boards and I was doing custom drivers for Morrow Designs. It even had one of the very first Syquest removable-disk drives in it, I think it was the 5MB model with MFM encoding. Unfortunately, 1986 was also the year in which Morrow Designs went tits up. I then owned the only UNIX-based machine which Morrow Designs had ever produced. Eventually I donated it to the VCF. -- Gary Jennejohn
