PDP8? Geez I don't feel so old anymore. The oldest computer I remember programming on was 486 with 4MB of RAM. I guess that's probably about as old as my 300E (1988). Of course I've had the honor to work on some VAX 4000's running OpenVMS. VMS like Mercedes is rock solid if you take care of it. Also being a software developer by trade, I continually see people who think they need a software solution for every data collection duty in their lives. For me, I let the receipts speak for themselves. Just put them in an envelope (relational of course). If you must keep records for your Panzer on the 'puter, make a backup. They just don't make things like they used to.
