Apple IIc-3

IIc FLAT PANEL DISPLAY

The liquid crystal flat display made by Sharp. It was released at the end of 1984. The screen looks horizontally to display full screen, and 80 digits display is possible. It is structured to be put on top with a simple stand, it is wonderful in terms of design, but carrying is not practical. Apple Design A variety of prototypes are introduced in Apple Design and some are those of integrated design. It is inferred that the designer intends to integrate, but it may have become a separate type considering the cost of the liquid crystal display at that time.


C・VUE DISPLAY PANEL

The LCD liquid crystal flat panel made by SWI INTERNATIONAL SYSTEM, USA. This is a structure that hinges are attached to the main body of IIC, it is structured to be able to fold up with the liquid crystal panel inside, and it can be carried together as one. Resolution etc. are equivalent to genuine products, but there is no black-and-white inversion function (there are cases where this is easier to see in word processors etc.) that was found in genuine products. I wanted to be sold as a portable system in combination with the battery of PRAIRIE POWER which will be described later. There is a matching canvas carrying case for carrying around.


VIDEO ACCESSORIES

There are two video outputs at the back panel of IIc. One is the standard RCA pin plug jack for video monitor as with IIe and the other is D-Sub 15 pin connector for video expansion. Apple's design team seemed to want to make this video extension port a standard design for future design, but during the progress of RGB monitor and standard design, it was designed differently from the RGB port adopted in the later IIGS,. On the other hand, the video expansion port of IIc is special from the technical point of view. The left photo is a video accessory for connecting to a TV system without video input. D-Sub Connect the modulator (upper left) to the D - Sub connector and connect it to the TV switch box (upper left) with RCA coaxial cable from the box. From the switch box connect to the TV with a 300 ohm parallel feeder wire. Channels can be switched between 3 and 4 channels with switches on the modulator side. There are small accessories, but they are neat design. On the other hand, the point that the designer could not incorporate this function into the main body seems to be slightly wrong. The pursuit of compact design and the point that the target of the user whether business use or home use could not be narrowed down is presumed to have concluded the style of such accessories.


VIDEO-7 Screen Enhancer

The left photo is Video extension attachment using D - Sub connector. RGB RGB interface (top), grayscale interface (bottom). Both are products of Video-7 Incorporated. The color interface supports IIc's text mode and three other graphics modes (low resolution, high resolution, double resolution). The description in the manual of the monitor and pin assignment that can be connected is only in RGB monitor, the details are unknown.

When I tried connecting AppleColor RGB Monitor for Apple IIGS using IIGS connection cable, it could displayed very clearly, but the display of G (green) and R (red) is reversed. According to the manual of the monitor, since pins 1 and 2 are red, and 5 and 6 are green signals, it is necessary to make own cables by replacing them. AppleColor RGB Monitor Since AppleColor RGB Monitor is not multi-scan type, it is a scan type of 15.734 Hz ​​(60 Hz), 15.659 Hz (50 Hz), it seems to be the design of this frequency band. For grayscale, gray scale signal is outputted to RCA standard pin jack and simulate color. It outputs very sharp grayscale. On the case side there is an output port of D-Sub 9 pin which is not in the manual. There is no description in the manual for this port, and although it has not been tried, it may connect to a VGA monitor.
