According to the 1969 catalog, BRPE11 + BRPEB6 is6 , 7 , or 8-level, 7/8" or 1" width, In-line feed hole633 wpm28VDC 1 ampere signal and tape feed out magnetsSee pdf page 10I thought that the parts book showed that the adjustable punch block would handle 5-8 level?I really need to get back to my BRPE project - I got a couple of the typesetter 6-level units (with leading feed hole) and convinced some machinist buddies that making a new 5-level in-line punch block would be a "challenge". Now I need to build some driver electronics and figure out how to feed it a character stream.On Wed, Jan 17, 2024 at 11:25 AM <pbirkel@gmail.com> wrote:______________________________________________________________Of possible interest is a poorly identified (and a bit rough) BRPE11 on eBay: https://www.ebay.com/itm/296166916217
I suspect from other sources (https://museum.wales/collections/online/object/a7dea37f-0f0a-3cfc-833e-f22b59972974/Paper-tape-puncher/) that’s a BRPE6 base -- hence the electrical support for an 8-level punch. However the CDC 160 used the BRPE11 and that was a 7-level paper I/O system. So apparently this may be a 7-level unit. The vendor confirmed that there are only 4 relays/solenoids on the right. I think that the mechanics and tape feed ought to work fine as a 6-level unit given the design of my BRPE21 tape feed mechanism.
I’ve suggested that the seller remove the punch cover and post suitable pictures. And relabel the listing appropriately!
Unfortunately this unit falls in the valley between supporting the much more common 5-level and 8-level tapes.
Interestingly https://collection.sciencemuseumgroup.org.uk/objects/co62588/westrex-8-hole-paper-tape-punch-punch claims that a “Westrex” unit used a BRPE11, yet was “8 hole”. I suspect that they included the feed hole in the count.
The "laid back" reel support is interesting (ignoring the fact that the reel isn't properly engaged in the photo). That design is confirmed by: https://www.computerhistory.org/collections/catalog/102696402
