PARALLEL PRINTER INTERFACE CARD
The card manual for connecting a
printer to the Apple II.
Apple has
advanced peripheral expansion cards so that Apple II can appeal to other
than the hobbyist group.
This card was designed for printers
with a 7/8 bit parallel port which was common for personal computers at
the time. According to the manual and catalog, it can connect with
printers such as Axiom EX 800, Centronics, Printoronix, SWTP PR 40.
It has a jumper block on the base board and is designed to correspond to
the pin assignment of various connectors according to the setting of the
jumper, and the manual has detailed description of the pin assignment of
each printer and the corresponding jumper method.

COMMUNICATIONS INTERFACE CARD
Manual for
Apple II Communications Interface Card (A2B0003X).
It is compliant with EIA's RS232
standard and can switch between half-duplex mode and full-duplex mode with
software switching at 110 baud or 300 baud.
In the manual,
the article of Jef Raskin of Dr. Dobbs Journal is quoted as it is.
Using this
card, two Apple IIs were able to connect, transfer data, connect the
acoustic coupler and exchange data using a telephone line.
Circuit Schematic The
attachment in the manual is accompanied by a list of Circuit Schematic and
PROM FIRMWARE, and the PROM FIRMWARE programmer was in charge of Dr. W. B.
SANDER known as the developer of Apple III.
In 1977, it is
said that Waz designed and manufactured a digital telephone card with John
Draper named “Captain Crunch” who has an independent office and, and this
card is thought to have followed the design. |
SERIAL INTERFACE CARD

compliant serial interface card manual.
It can be set
from 75 baud to 19,200 baud with a dip switch.
Installation method, transmission /
reception method, dip switch, timing, etc. are described.
FIRMWARE At the end of the book are a circuit diagram and a source list of
FIRMWARE.
Diagrams are
the ones in the company use as they are, and they can read up to the
signature of the approver.
Since the
manual number is relatively small, it is considered as the original
genuine expansion card as Apple II. |
PROGRAMMER'S AID#1
In the
original system of Apple II released in 1977, among the 12 KB ROM area (2
KB × 6, F 8, F 0, E 8, E 0, D 8, D 0 socket), F8 used 2 KB monitor, the

DISK OPERATING SYSTEM INSTRUCTION
AND REFERENCE MANUAL
The release dates of the DOS version
are as follows.
This is a
manual of DOS 3.2 version.
It was attached to Disk II.
The right is a Japanese translated version of the above
manual by ESD Laboratory.
It has been
carefully translated to reference materials.
According to
Yutaka Saito's book "Under the tree of apples" (published by ASCII), ESD
has grown rapidly due to the import of Apple II, borrowing a 3 floor
building near Yushima Aria in Tokyo in the middle of 1978, employees 50.
One floor among the building was opened as a showroom (famous shop named
as “Computer Love Hongo”).
The excitement
of the time in the personal computer generation period is transmitted. |
