I don't think HP every did one, but I remember seeing other companies
making them. No names pops up in my head right now, though. This was a
long time ago. (Still have my 41CX around.)
Annoyingly I realised I picked up an HP41C manual in a charity shop a
few months back, too. If I'd remembered that I had a manual for it at
home I'd have picked it up straight away...
