C41H64O13
(gcide) | digitoxin \dig`i*tox"in\ (d[i^]j`[i^]*t[o^]k"s[i^]n), n. (Chem.)
A steroid glycoside, one of the cardiotonic chemical
substances which is extracted from the foxglove. It is a
white, crystalline substance (C41H64O13), and is a
3-substituted triglucoside of a steroid, related structurally
to digitalin and digoxin. It is used as a cardiotonic for
treatment of certain heart conditions, such as congestive
heart failure. Chemically it is
(3[beta],5[beta])-3-[(O-2,6-Dideoxy-[beta]-D-ribo-hexopyranosyl-(1[rarr]4)-O-2,6-dideoxy-[beta]-D-ribo-hexopyranosyl-(1[rarr]4)-2,
6-dideoxy-[beta]-D-ribo-hexopyranosyl)oxy]-14-hydroxy-card-20(22)-enolide.
The related compounds digitalin and digoxin are also
extracted from the foxglove (Digitalis lanata and
Digitalis purpurea). The class of steroid glycosides having
cardiotonic properties are refered to as the cardiac
glycoside group. --MI11

1541
(foldoc) | Commodore 1541
1541
The best known floppy disk drive for the
Commodore 64. The 1541 was a single-sided 160 Kb drive but
converting to flippy disks would give another 160 Kb.
The disk drive used Group Code Recording and contained a
6502 processor as a disk controller. Some people wrote
code for it to vibrate the head at different frequencies to
play tunes.
The transfer rate was about 300 bytes per second. The 1541
used a bit-serial version of the IEEE 488 parallel
protocol. Some third-party speed-ups could transfer about 4
kilobytes per second over the interface, and some "fast
loaders" managed up to 10 kbps.
The Commodore 1570 was an upgraded 1541 for use with the
Commodore 128.

golf ball printer
A slow, letter-quality printing device and
terminal based on the IBM Selectric typewriter. The
print head was a little sphere resembling a golf ball, bearing
reversed embossed images of 88 different characters arranged
on four parallels of latitude; one could change the font by
changing the golf ball. The device communicated at 134.5 bits
per second, half duplex. When the computer transmitted, it
physically locked the keyboard.
This was the technology that enabled APL to use a
non-EBCDIC, non-ASCII, and in fact completely non-standard
character set. This put it 10 years ahead of its time -
where it stayed, firmly rooted, for the next 20, until
character displays gave way to programmable bit-mapped
devices with the flexibility to support other character sets.
