TABBY.PRN
From Nick Higham’s note on Typewriter Art, referring to Bob Neill’s Book of Typewriter Art (with special computer program). Nick wrote the special program back in the early 1980s. What I did to get this output:
- open Nick’s program in GW BASIC under Dosbox;
- modify the program so it wrote the Epson FX printer codes to a file;
- convert those codes to PostScript using epsonps;
- convert it to PDF with ps2pdf.
Bob Neill’s art relies on being able to set a typewriter’s vertical advance to the same value as its horizontal one, and also being able to overprint lines to get darker results. The results are pretty good: tabby.pdf

ð’³ / ༳ == ( ⑽ – ð¹ ) * ( ð’² / ð…‰ ), of course
I just got brian d. foy’s Learning Perl 6 from the library. It’s a pretty good book, though it’ll take a good few readings for some of Perl 6’s features to stick.
Since Perl 6 is built using Unicode from the ground up, it does two rather wonderful things when dealing with numbers:
- regular expressions match numerals beyond 0–9: ٤ is as much four as 4
- numeric constants can (pretty much) be expressed in terms of Unicode values in your Perl 6 source code. Assigning π to a variable does what you think it does. Dividing by ¼ is the same as multiplying by, well, ٤.
So herewith a table (probably incomplete, and very unlikely to render properly for you) of Unicode glyphs accepted by Perl 6 as numeric values:

$ perl6 To exit type 'exit' or '^D' > ð’³ / ༳ == ( ⑽ - ð¹ ) * ( ð’² / ð…‰ ) True
What does it evaluate to? Well:
- 𒳠‘CUNEIFORM NUMERIC SIGN SHAR2 TIMES GAL PLUS MIN’ represents 432000
- ༳ ‘TIBETAN DIGIT HALF ZERO’ represents -½
- ⑽ ‘PARENTHESIZED NUMBER TEN’ represents 10
- ð¹ ‘RUMI NUMBER FIFTY’ represents 50
- 𒲠‘CUNEIFORM NUMERIC SIGN SHAR2 TIMES GAL PLUS DISH’ represents 216000
- ð…‰ â€˜GREEK ACROPHONIC ATTIC TEN TALENTS’ represents 10.
Definitely into just because you can doesn’t mean you should territory, and a feature to make the Pythonistas reach for the Zantac again, poor dears.

SBC6120 build: day 1(-ish)
SBC6120 (RBC Edition) with all the sockets Just started on a SBC6120 RBC Edition kit. It’s a DEC PDP-8-compatible single board computer that uses a CMOS chipset from the early 1980s. Yes, it will be very slow, even with the optional speedy 8 MHz oscillator installed. With a 12-bit processor and 32 kilo-words of RAM, this is definitely going to be a Slow Computing device.
Lots and lots of sockets. So many sockets. It’s quite soothing soldering them all in, one hole at a time. It looks like it’ll go more quickly than the Zeta did.
> Does anyone know what each of the pins on the 6502 CPU chip in the Apple II Plus does?
They all plug into the socket on the motherboard to keep the chip from drifting away. – c.s.a2 FAQ of yore -
Now *that’s* a Lego bridge …
