https://www.tes.com/news/telly-trolleys-and-ohps-5-pieces-outdated-teacher-tech The telly trolley, the overhead projector, the banda machine, chalkboard and roller board. So these bits of kit that those of us who started teaching in the 70s and 80s are only too familiar with are now considered obsolete. OK, the telly trolley has pretty much had it's day but at least you can still display your OHP transparencies (lovingly crated in all different coloured permanent pens) if the school wi-fi goes down and you can't access that all singing, all dancing power point. The banda machine was pretty primitive but it was fairly simple, if a little messy, and never broke down unlike modern photocopiers. It was also considerably cheaper to run. With school reprographics budgets being slashed these, as I have predicted on other forums, may well be coming back in an updated reincarnation. As for chalk and roller boards, well, don't teachers still use their modern equivalents - the white board and marker pens? I remember about 5 years ago my old school was refitted with brand spanking new interactive whiteboards during the summer hols. The only trouble was that when we turned up after the summer break, no training or instruction was given on how to use them so when I left last Whitsun, the majority of staff still only used them to log into SIMS, take a register and then off they went and out came the whiteboard pens. At about £3000 per interactive display, these must have been the most expensive whiteboards ever. Let's not write off all this seemingly outdated technology too soon.
