Thank you for banner! I used the data, abliet
modified, 40 years ago
in 1981, for a banner program as well, on an IBM 1130 (manufactured 1972)
so it could print on an 1132 line printer. The floor would vibrate
when it printed those banners. I used "X" as the printed char as the
1132 did not have the # char. But those banners looked great!
I wrote it in FORTRAN IV. On punched cards. I did this because
from 1980-1982 I only had access to UNIX on Monday evenings from
7PM-9PM, using a DEC LA120 terminal, it was slow and never had
enough ink on the ribbon.
I had only 8K of core memory with only EBCIDIC uppercase so there
were lots of compromises and cleverness needed -
- read in a 16-bit integer as a packed two 8-bit numbers
- limit the banner output to only A-Za-z0-9 !?#(a)'*+,-.=
- unpack the char data into buffer and then process it.
- fix the "U" charater data
- find the run-lenght ecnodings that could be consoldated to save space
(seeing those made me think it had to have been generated data)
The program still survives here - http://ibm1130.cuzuco.com/
(with sample output runs)
Also since I had to type all those numbers onto punch cards
with a 029 keypunch, to speed things up I coded my own free-form
atoi() equivalent in FORTRAN, reading cards, then packed two numbers into
a integer, then punch out those numbers along with card ID numbers in columns
73-80 on the 1442. This was many weeks of keypunching, checking,
fixing and re-keypunching.
That code is here http://ibm1130.cuzuco.com/ipack.html
When done the deck was around 8" or so. It took well over a
minute to read in the data cards, after complition.
Again thanks! Many hundreds of banners for many people were printed
by this, around 2 to 3 a week, until July 1982, when that IBM
was replaced by a Prime system. I still have many found memeories of
that 1130.

Nice. I wrote a banner
program in 1984, as a freshman in college for the
TRS-80 Model 100 laptop (with an 8x40 LCD), in BASIC, which if I recall
was the OS of the thing? It would peek the character ROM and use the
encodings (characters were stored in ROM as a 2d binary array bitmap) to
determine what to print to the printer and did some form of vertical and
horizontal expansion to reasonably fill up the sheets. I don't remember
if I took the horizontal and vertical expansion as input from the user
or what (it's been a while, and the code is long gone), or if I just
figured out what looked good on the ol' dot matrix we had access to and
set them... but it was, at the time, my crowning achievement in
programming. Everyone else in the class took pages and pages of code to
print their banners without reference to the character ROM, whereas mine
did it in very few lines of easy to understand, if somewhat complex (not
complicated, mind you), code (the story of my much later career).
Wow, that brings back memories :).. snip! after writing what turned into
my life story, I decided to spare y'all. Suffice it to say my early
experiences with computation (Commodore PET, TRS-80 Model 100, DEC
Rainbow 100) and later more formal educational experiences (my first
real maths and upper division cs professors) changed my life's
trajectory and gave me the tools to help me rise out of decades of
extremely harsh circumstances. Thank you Dennis, especially for C. I
wish I could have known you and thanked you personally. C was my vehicle
out of the depths of poverty and hardship. Sigh, sniff, and smile. Now,
I explore Unix, both historic and modern for fun, pester y'all with
questions, opinions, and sundry, teach CS and IS for fun and pay, and
hope that I can share 1/10th of the joy I experience every day with my
students and inspire them to pursue careers in the field.
Banner on!
