Re: ISO: Cipher F880 tape drive, Fujitsu Eagle disk drive
Ok, I think I have the 2312 or 2322. Could emulate an RM03 disk or two. Starting to work on digging things out of the shed, the Decsystem20 box is in the back there somewhere...

Yea, it isn't as straight a line as I paint it...

This explanation ignores that terminals like the VT52 pre-date the PC world
and were made for some custom gear that DEC engineers made that had no
relationship to NTSC. VT-52 was 1974 and had 80x24 lines. The Apple ][ was
also designed for the TV, but wasn't 24x80 because most TVs at the time
couldn't cope, but even it had custom CRTs and even on those custom CRTs
there was no 80 column mode standard. But the VT-52 was just a reflection
of the VT-50 which was 80x12 lines which was a reflection of the
Datapoint-2200 which was introduced in 1970 which was 80x12 lines as well.
DEC copied this, I've been told in classes in school ("the early terminals"
is all I recall now), but I have no good references between the dots here.
So the connection between 029 punch cards and terminals is clear... But
beyond that back to hollerith and the census to the 029 punch cards is less
clear...

Ah, that's true... And the whole 80 column thing is pervasive today as a
standard for any reason...

RE: Monroe 7860
As Monroe Systems is still in business. Contact them, they might have an historian that could help you. https://monroe-systems.com Also, there a brochure for sale on ebait. There is a preview of 4 pages that supplies some general info (for free) https://www.ebay.com/itm/VINTAGE-1983-MONROE-7860-DESKTOP-ACCOUNTING-CALCULATOR-BROCHURE-23-LB-32-CHAR/381996877124?hash=item58f0c9c544:g:NTAAAOSw32lYwl6G In 1972, I programmed Burroughs L3000 accounting machines that could read magnetic ledger cards. I wonder if the Monroe could use the same kind.

Great. Now I can finally get copies of my Siggraph papers.
