Apple IIc-1
APPLE IIc SERIES IIn 1984, IIc was announced as the fourth model of the Apple II series following the announcement of Lisa and Macintosh. I would definitely choose this machine if it is said to be the only one among the successive apple II. A cute machine dressed in a white body called Apple Fog (fog color of Apple) or Snow White designed by Hartmunt Esslinger in Germany combines with a 9 inch monochrome monitor to show a very attractive appearance. Although the main body looks the same, there are four kinds (5 types including IIc Plus) depending on the difference between built-in ROM and RAM. It is also interesting that the case of the nameplate on the back etc. is slightly different from the manufacturing age and the fabrication factory. |

INSIDE IIc
The main body is fastened with 6 bolts on the back, and it can be easily
disassembled if it is removed.
Decomposition is carried out while shifting the rear fit little by little, but a
bit of trick is needed.
The first place in the horizontally elongated IC vertically aligned is 65C02
(1.023 MHZ), and the lateral side is ROM.
The design of the motherboard made of 21 chips is concise and beautiful.
This board realizes the functions of Apple IIe + RC 232 × 2 + video output × 2,
mouse / joystick port, disk controller and so on. |
ROM IN IIc The left photo is expanded part of IIc ROM. Copyright of MICROSOFT 1977 and APPLE 1977-1983 are in line. It is known that there are five types of IIc ROM versions including IIcPlus. This can be confirmed by entering the monitor mode (*) with CALL - 151 from the mode (]) of Apple software BASIC and examining the FBBF address.
It is a big difference that Unidisk 3.5drive can connect with 3.5ROM II C or later, and that it is possible to install additional memory since Original "Memory-Expandable" IIc, and in the case of 3.5 ROM IIc, allocating AppleTalk to SLOT # 7 (which did not realize after all), shifting the Mouse Map from SLOT 4 to SLOT 7, it seems to be reflected the change mind of the designer. IIc have been given a nickname from Bert, Ernie, or the characters of Sesame Street for each version of ROM. |
