I suspect it's still made. I just read an article a few days ago about a place that was using punched tape communication systems. 5 bit is what radio amateurs call RTTY -- Teletype model 15 or model 28 stuff. You might try ham radio lists for this. Classic computer folks are more likely to have 8 bit (1 inch wide) tape. paul (ni1d) On Apr 19, 2013, at 4:11 AM, Mark Wickens wrote: Hi folks, I've got a crazy idea, so please humour me... Does anyone have a length of punched tape they could send me? Ideally tape that is five bit, which is 11/16 inch wide I believe. I'm presuming that there is nowhere to obtain paper tape anymore? Thanks, Mark.
