Um. I don't recognise the name, but there were some early Honeywell PC type things called "Microsystem Executive". This was a design bought by Honeywell after the British company responsible, Future Technology Systems, went bust. The FTS series 86 was sold as the "Non-compatible compatible". OS was a version of CPM-86 with MS-DOS compatibility, multitasking, and one or two other fun features, called Concurrent DOS, and sold by a software house whose name I can't remember (Pegasus? Something beginning with P, I think). Despite its PC-incompatibility - architecture quite different at the hardware level - Lotus 123 version 1 ran without modification, and even drew graphs on the monchrome monitor... I have an FTS 86 somewhere. It was far too expensive, even tho' my father got a huge discount for not suing FTS for breach of contract when they failed to maintain our Series 88 machines. After FTS folded, Honeywell-Bull maintained it for a while; they gave that up at about the time Honeywell sold the rest of their computer arm to Bull group. More than that I can't remember, offhand. If you want more info, I'll see what I can find, but it won't be much...
