Display stationsModel 2, 3284 Printers Model 2, 3286 Printers Kodel
2, 3287Printer Models 1 and 2, and 3288 Line Printers Model 2. To
support this configuration, the following are required:
--Device Adapter feature(13250) is required if more than 4 devices
are attached to the 3272.Up to 4 additional devices can be
attached with each device adapter.
--A 3271/3272 Attachment(18330) is required to attach each 3287 Printer. • IBM 3274 Control Unit Kodel lB (supported as a 3272) for attachment
of up to 32 display stations and printers. All of the 32 devices can
be 3278 DisplayStations Models 2, 3, and 41 (supported as 3277s),
3287Printers Models 1 and 2, (supported as 3284s or 3286s), and 3289
LinePrinters Models 1 and 2. (supported as 3288s). A maximum of 16
of the 32 devices can be 3211 DisplayStations Model 2, 3284 Printers Model 2, 3286 Printers Model 2, 3281 Printers Models 1 and 2, and
3288 LinePrinters Kodel 2. To support this configuration, the
following are required:
--The basic 3214 ControlUnit permits attachment of up to 8 devices
(3278, 3287, and 3289). At least one 3278 is required.
--Each of the Terminal Adapter TypesAl, A2, and A3 ('6901, 16902, and 16903) permits the attachment of up to 8 additional devices per
adapter (types 3218, 3281, and 3289).Only one of each type
terminal adapter is permitted. Terminal Adapter TypeAl is a
prerequisite to Type A2, and A2 is a prerequisite to Type A3.
--Terminal Adapter TypeBl (#1802) permits the attachment of up to 4 additional devices (types 3277, 3284, 3286, 3287, and 3288). Only one adapter is permitted.
--Each of Terminal Adapter Types B2, B3, andB4 (t1803, #7804 and
#7805) permits the attachment of4 additional devices per adapter
(types 3211, 3284, 3286, 3287 and 3288).Only one of each type
terminal adapter is permitted. Terminal Adapter TypeBl is a
prerequisite to Type B2, Type B2 is a prerequisite to Type B3, and
Tvpe B3 is a prerequisite to TvpeB4. Terminal Adapter Tvpes Al and B3 are mutually-exclusive. ----- --A 327q/3276 Attachment (18331) is required for each 3287 Printer Models 1 or 2 that attaches to the basic 3214 Control Unit, or that
attaches to Terminal Adapter Types Al, A2, or A3. A 3271/3272
Attachment (#8330) is required for each 3287Printer Model 1 or 2
that attaches to Terminal Adapter Types Bl, B2, B3, orB4. And only needed if a Type B adapter is used:
--Control storage Expansion feature(11801) provides the ability to
access control unit storage addresses above 64K.
--Extended FunctionStorage feature ('3622) provides additional
storage required to support particular attachments or
configurations. ControlStorage Expansion feature (11801) is a
prerequisite.
