High-Resolution Graphics Unit for Video Genie

High-Resolution Graphics Unit for Video Genie

This expansion unit for the Video Genie provided a high-resolution monochrome graphics overlay of 384x192 pixels. The high-res layer xor'ed with the text layer and overlapped it exactly - each text character mapped to a 6x12 block of pixels. The software interface was via four I/O ports and was therefore not particularly fast.

 
Tandy 1000 EX Personal Computer

Tandy 1000 EX Personal Computer

The Tandy 1000 EX was designed as an entry-level IBM compatible personal computer. Initailly marketed as a competitor to IBM's PCjr, the the EX was a compact computer that had the keyboard and 5.25" floppy drive built into the computer casing. The 5.25" drive was accessible on the right-hand side of the computer. The EX was marketed as a starter system for people new to computing, and sold for US $1000.00 from RadioShack in December 1986. The EX and later the HX would be among the most popular of the Tandy 1000 line because of their (relatively) low price. The EX doubled the on-board memory to 256kB.

The EX was upgradable by Tandy PLUS cards, and system had bays for three. The PLUS cards' connector was electrically identical to the ISA slot connector, but used a BERG-style 62-pin connector instead of a 62-contact ISA card edge connector. The RAM could be upgraded in the EX and later the HX to 640kB, but required a PLUS memory expansion card. This card also provided DMA. Other PLUS cards could be installed to add serial ports, a 1200 baud modem, a clock/calendar and bus mouse board and a proprietary Tandy network interface.The 1000 EX came with MS-DOS 2.11 and Personal Deskmate on 5.25" 360 kB diskettes.

The 1000 SX came with MS-DOS 3.2 and Deskmate II on 5.25" 360 kB diskettes. While Deskmate II used a text-based interface, Personal Deskmate used a graphical interface and also supported a mouse-like cursor using a joystick-mouse driver or a Tandy bus mouse. The MS-DOS was a version specialized for and only bootable on the Tandy 1000, as it would announce on the screen of any other PC-compatible one tried to boot with it; it included a version of BASICA (Microsoft's Advanced GW-BASIC) with support for the enhanced CGA graphics modes (a.k.a. Tandy Graphics or TGA) and three-voice sound hardware of the Tandy 1000.

Nintendo NES Zapper

Nintendo NES Zapper

The NES Zapper was an electronic light gun accessory for the Nintendo Entertainment System (NES) and the Japanese Famicom. It was released in Japan for the Famicom on February 18, 1984 and alongside the launch of the NES in North America in October 1985.

The Zapper allows players to aim at the television set display and "shoot" various objects that appear on the screen such as ducks, clay pigeons, targets, cowboys, criminals or other objectives. The Zapper is used on supported NES games, such as Duck Hunt and Wild Gunman. The Zapper could also be used on the title screens of games to move the cursor—done by pointing the device away from the screen and pulling the trigger—or starting the game (pointing at the screen and pulling the trigger).

MGT Plus D Interface

MGT Plus D Interface

The +D (or Plus D) was a floppy disk and printer interface for the Sinclair ZX Spectrum home computer, developed as a successor to Miles Gordon Technology's earlier product, the DISCiPLE. It was designed to be smaller, cheaper, simpler and thus more reliable.

It discarded a number of the less important features of the earlier product — the network and joystick ports, the inhibit button and the pass-through connector — and replaced its ancestor's plastic wedge-shaped design which fit under the Spectrum with a simple flat metal slab which protruded from the rear of the computer.

It provided only floppy disk and Centronics parallel interfaces, plus a non-maskable interrupt button. The +D's casing was simple folded steel, which was not only stronger than before but acted as a heatsink, improving reliability. Apart from the missing ports, though, it was software-compatible with the larger device.

 
TI-99/4A Speech Synthesizer

TI-99/4A Speech Synthesizer

This highly popular plug-in speech synthesizer module was available for the TI-99/4 and 4A. Speech synthesizers were offered free with the purchase of a number of cartridges and were used by many TI-written video games. The synthesizer uses a variant of linear predictive coding and has a small built-in vocabulary. The original intent was to release small cartridges that plugged directly into the synthesizer unit, which would increase the device's built in vocabulary; however, the success of software text-to-speech in the Terminal Emulator II cartridge cancelled that plan. Cartridges sold to expand TI's Speak & Spell vocabulary are compatible with the speech synthesizer, with the added vocabulary being accessible through TI Extended BASIC. In many games (mostly those produced by TI), the speech synthesizer has relatively realistic voices.

TI Little Professor (boxed, with cards)

TI Little Professor (boxed, with cards)

The Little Professor is a backwards calculator designed for children ages 5 to 9. Instead of providing the answer to a mathematical expression entered by the user, it generates unsolved expressions and prompts the user for the answer

When the user turns the Little Professor on and selects a difficulty level, an incomplete equation such as "3 x 6 =" appears on the LED screen. The user has three chances to enter the correct number. If the answer is incorrect, the screen displays "EEE". After the third wrong answer, the correct answer is displayed. If the answer supplied is correct, the Little Professor goes to the next equation. The Little Professor displays the number of correct first answers after each set of 10 problems. 

Compared with the early Little Professor with the LED display this one uses a LCD to ask the child one of thousands pre-programmed math questions. 

Instead of the membrane keys introduced few years ago with the Little Professor (1982) in the United States, this one followed the Little Professor (UK) developed in Europe and uses again normal keys. The technology of the keyboard is identical to well known scientific calculator. Compare it with the TI-30.

Date of introduction: 1985
Display technology: LCD
Size: 5.3" x 3.3" x 1.3"  
Weight: 2.3 ounces
Batteries: 2*LR44
