Thanks everyone!
I hadn't even bothered to look on eBay for it recently. As it was on an Amiga Computing Coverdisk in a full version, I had a look round to find out which issue it came with. I found out it was Issue 59, or at least that was ONE of their coverdisks which it was included on. It was called Coverdisk No. 42 though, so I suppose that means early issues of Amiga Computing came without coverdisks at all, but I can't take the time to look ithat up now.
I managed to downlioad an ADF of Amiga Computing Issue 59 Coverdisk as an ADF file from
www.archive.org and I've already got it up and running! It accepts 19 as the current year as well. I think this software is fantastic and particularly suitable for individuals, instead of for companies. Now to work some more miracles with my finances!
One problem may be that I've recently been away to Germany and the Netherlands where all my spending was in Euros, although during this time some charges or penalties for using Euros were made by my bank in Pounds for using Euros and I had some regular charges for subscriptions made in Pounds by my ISP and by Spotify, as well as in Euros by two online German TV streaming services. Should I do a seperate file for any periods of time when I was in the Eurozone, or what does anyone suggest? A similar situation could have occurred in 1993 when this Coverdisk came out, only then there would have been 3 currencies, £, fl (Dutch Guilders), and DM.
