Used them at my Dad's PCB manufacturing business in South Wales for standard accounts and payroll, then went on to develop production control software for the company with my cousin: still have a pile of 3.5" floppies with Pascal code on them somewhere. Happy days!
At one time we actually ended up manufacturing PCBs to go into various Apricot machines: I vaguely recall the odd little LCD display ("microscreen") on some of the keyboards: did it have printed carbon pads for the membrane keyboard?
As far as we were concerned, they were great machines.
After using InDesign CS6 for many years, (small-scale print/publishing), and trying Affinity Publisher for a time, I stumbled across VivaDesigner a while ago: https://viva.systems/designer/
I don't know how it compares to QuarkXpress, but it's a pretty good commercial replacement for InDesign / Publisher in my personal opinion: it has decent typography, styles, and good options for PDF/X-4 export (with FOGRA39 as a destination etc). I've also successfully imported .idml
They have various perpetual / subscription options (I'm on a commercial perpetual licence), a decent trial version, and they even do a Linux version, which works great for me on Mageia9.
I've contacted their support a few times, and they've been very responsive, professional and helpful, which was a pleasant surprise.
