Peripherals
Another topic one can't write anough about. I don't have enough information to make a decent page, so any comments would be appreciated! The list is now quite short for how long it could be, and doesn't contain the information I'd like to see here (not enough numbers, specs...). Please help me!
Teletype consoles, printers:
ASR33: Automatic
Send and Receive. "The" classic teletype, with upper-case only. Printing
speed was 10 cps due to the fact, that it was almost fully mechanical.
Data speed was 110 bps (it required two stop-bits, so each char takes 11
bits on the line). It could have an optional papertape reader/puncher on
the left side.
ASR38:
The lower/upper-case version of the ASR33
LA30 DECwriter:
30 cps matrix-consoleprinter
LA36 DecWriter II:
9-pin matrix-consoleprinter. It came in receive/send and receive-only versions.
Speeds: 30 cps/300 bps.
LA100 LetterWriter: 240 cps in draft-mode,
30 cps in high quality. 2 built-in fontset, graphics.
LA120 DecWriter III: 180 cps printer,
75-9600 bps data
LP11: high-speed lineprinter, 1100 line/min
LS11: normal lineprinter, 60 line/min
LV11: high-speed printer/plotter, 122880
dots/min
CRT terminals:
VT05: One
of DEC's first CRT-terminals, with a futuristic housing.
VT52:
A classic video-terminal, with cursor-, numeric and function keys.
VT55: A VT52 with built-in graphics printer
VT62: A VT52 with reverse video
VT100:
Another "the". It became a de facto standard. 24x80 or 14x132 characters,
detachable 83-key keyboard.
VT103: A VT100 with LSI-backplane in
the box.
VT125:
A VT100 with graphical capabilities.
VT220:
A CRT-terminal with 12" screen, and VT52/100 emulation. 80x24 or132x24
char resolutions, 105 keys, 75-19200bps, printerport.
VT240: 12" monochrome graphical terminal,
with a resolution of 800x240.
VT241: 13" color version of the 240
Card readers/punchers:
CR11: It
could read 80 column cards at 300/minute speed
CD11: high-speed (1200 cards/min) card
reader
PC11/PR11: high-speed papertape reader/puncher,
300 cps reading speed, 50 cps punching
Magnetic tape drives:
TU10: Classic
big tape driver, 5-20 MB on 2400 ft 0.5" wide tape
TU55:
Designed for the DecTape magnetic media, to store 250K of block information
on a 1" tape. These tapes were handled just
like a disk drive with a 'normal' file system.
TU56: An
enhanced version of the TU55.
Another picture
TU58: This
drive used the DecTape-II tape cartridge.
It could store 256K with 800bpi density. Average access time was 9.3 sec.
TU60 (DECcasette):
It was designed to replace papertapes. The tape-media looks like the one
used with audio casettes, but it uses a different metal-oxyde.
TU80, TU81,
TU81+: Big 9-track tape-drivers for heavy
backup duties.
TK50: A driver unit for a 0.5" magnetic
media, that could store 96 MB of data.
TK70: The enhanced version of the TK50.
It can read TK50 tapes, but can't write on them. The drive is still used
in many VAX-systems.
Floppy-meghatók:
RX01: Dual
8" floppy unit. One disk holds 250K data.
RX02: Successor
of the RX01, with double data density.
RX50: 5.25"
