This is the old OS named Oasis. I knew Oasis in 1986, in one version for the Olivetti M-20. I couldn't take the manual and disks before they go to the dumpster when my old employeer went down (together with one M-20, one AT&T 3b1, some Amstrad PCW's, some Olivetti M-24 and M-28, and so on... all with software, licenses, and documentation). Later, Oasis was converted in Theos, and Theos 386. Is a protected system. Multiuser, well documented, with one SDK. It has a good quantity of users, but in Spain there is a lot of them. Mostly in pharmacy and supermarkets. In this last case, it permits to control a lot of POS from one central computer. It has a multiuser Basic interesting, and the application that I saw permits even to see online the evolution of the business at minute (of course I speak of application key-in-hand). During the eighties there was only MSDOS here.WIndows was good for desktops, but ever cause some afraid in the business users... Unix was expensive and nobody knew it at all here, far from the University and Scientific business. Theos was expensive, but the seller (TISA) came to the buyers of the system with one system ready-to-use, easy of understand, and well covered for technical problems. Business didn't discussed about the anti-copy protection and paid. I know some system programmer's of Theos here. Very competent people. But the certain is that they begin to touch other fields of work. In the POS field, Windoze is entering step by step, even when the text-mode applications are realized (and purchased) yet.
