HOME COMPUTERS
TI 99/4A (Release:1981,End:1984)
CPU : TI TMS 9900 (with 256 bytes 'cache', actually it accesses to 256 bytes of RAM) @ 3,3 MHz (The TMS-9900 was the only 16-bit processor to be used on a 1981 home-computer).The CPU can only access its main memory through the 9918A, hence the low speed of the system.
COPROCESSOR : TMS 9918 (TMS 9929 in Europe) - Video / Sprite (8bit)
.The TMS-9918A was used in the ColecoVision/ADAM, MSX series.
RAM : 16 KB - Memory expansion card can be added, 4 KB or 32 KB (up to 52 KB)
VRAM : 16 KB
ROM : 26 KB, 8 KB ROM connected to the CPU + 18 KB ROM in byte-serial bit-mapped circuits (usually known as GROM, Graphic Only Memory)
Text modes : 32 x 24 (16 colors), 40 x 24 (2 colors)
Graphic modes : Multicolor mode 48 x 64 with 16 colors,
256 x 192 with 16 colors (only accesed via machine code)
Sprites :
The display chip also has a nifty sprite engine. Up to 32 sprites are supported. Up to 4 (bits of) sprites can share the same scan line, though. Any more sprites aren't drawn on that scan line. Some programmers used this limitation to create special effects for games. (only with TI-Extended Basic)
Colors : 16
Sound : 3 channels, 5 octaves (110hz to 55khz) and 1 noise channel (periodic and white)
I/O ports  : Tape interface (450 baud), RGB video, Joystick (2), cartridge slot (Solid State Cartridge).The joystick port is incompatible with Atari joysticks, despite the fact that it's a male 9-pin D socket.
OS : Its ROM BASIC was even more horrible than the Commodore 64's: there was a minimal set of graphics/sound routines, but no POKE/PEEK/CALL commands for accessing the ROM directly or writing machine code programs. One of the most popular modules, Extended BASIC, offered access to almost all of the hardware (even optional peripherals, like the famous Speech Synthesiser, with a built-in vocabulary of 300 words).
Retail price :  99 (UK, 1983)

Please do not ask me questions like : " Will you sell me your ***** PCB / tabletop / computer ? " Sorry but can't sell. If I wanted to get rid of them I wouldn't have bought them myself in the first place. I'm not in this to try to make money off of people. I just collect them.
