• 1541 — Commodore 1541
• commodore 1541 — (storage)   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.
• ibm 2741 — (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.
• rfc 1341 — (messaging, standard)   The June 1992 RFC defining Multipurpose Internet Mail Extensions (MIME). This RFC has been obsoleted by RFC 2045, RFC 2046, RFC 2047, RFC 2048, RFC 2049, and BCP0013.
• rfc 1441 — (networking, standard)   The RFC introducing SNMP v2.
