Yes indeed - in 1988 I worked on the source code of 'Visula', a PCB design CAD package from Racal Redac Systems. All right, it was running on Apollo workstations using native Apollo graphics under Domain, rather than X Window System on top of the mickey-mouse 'Apollo Unix' shells - but Apollo was absorbed by HP a year or so later, Domain was killed off in favour of HP-UX, and I'd bet that Racal would have moved Visula over to X/Motif well before 1992! And most important, it used Informix as a database for sourcing the metafile descriptions from a catalogue of designable-in circuit components. I can provide some documentation on this, and I am in touch with the offices where the product was authored.
