Any Acorn computer experts? I need help troubleshooting

We still have 3 Acorns (A7000's) for the more severe disabled children as they can do pretty much anything and until today never break it. One restart later and it all works.

Today Oxford reading tree level 5 starts giving an error message. Internal error no stack for trap handler. Illegal instruction PC=021446cc: Register at 0003A80C any ideas what this means or how to fix it? I tried reinstalling the program which is about all I can do on an Acorn. No luck.

Bit of a long shot I guess not many people know about Acorns anymore.

Memory settings, hrrm right click, middle click not the green acorn? Now you mention it I seem to recall font size memory often needed boosting.

Just one machine. Virus is unlikely, as nothing has changed, no network, no new disks. Big problem if it is, as all the virus checkers don’t work anymore. Could be hardware but no reports of other programs not working. Then again it is a teacher perhaps they didn’t bother to tell me. Time to gather more intel.
