The punched tape machines I have seen with 6 channels are typesetting devices, from early tape operated Linotype machines (1940s vintage) to 1960s or 1970s era phototypesetters. Those are upper/lower case. > > paul > >>> On Dec 8, 2021, at 2:23 PM, Mike Katz <bitwiz at 12bitsbest.com> wrote: >> >> I thought I had recalled that Baudot was 5 bits but the paper tape is 6 bits across and I don't know of any 6 bit character codes except for DECs upper case only character set and even their paper tape had 8 bits so I guessed Baudot. >> >> On 12/8/2021 1:16 PM, Paul Koning wrote: >>> 5 bit; if it really were 6 bits it would typically be typesetting codes. >>> >>> That's a relative of the machine used as console terminal on Dutch Electrologica X8 computers; I recognize the "Iron cross" symbol, the figures shift character on the D key.
