SINCLAIR TIMEX TS2068
Z80A processor
clocked at 3.58Mhz
AY-3-8912 Sound
Chip (same as 128K Spectrums) w/ clock 1.76475Mhz It is attached to different
ports compared with the Spectrums, so you don't hear AY music when playing
Speccy games (of course, it can be overcome). I mention the clock rate
here because it is slightly different from the Spectrum's.
72K (48K RAM;
24K ROM) which is bankswitched between three internal 64K memory banks
called the HOME bank (16K ROM, 48K RAM), the EXROM bank (8K ROM; this one
is not completely decoded and can only hold 8K), and the DOCK bank which
is empty and is reserved for cartridges. The memory is bankswitched in
8K chunks.
The BASIC is
a superset of 48K Spectrum BASIC (ie - has a few commands added).
A cartridge dock
is located under a door on the right side of the computer.
Two joystick
connectors (not compatible with any Sinclair joysticks)
RF out, Composite
video available on jacks. RGB signals available on rear edge connector.
Hardware was
nicely designed to support DMA and memory bankswitching.
Video Modes:
256x192 pixel, 32x24 attributes (Spectrum screen)
256x192 pixel,
32x192 attributes (extended colour mode)
Dual screen mode
where you could flip between two Spectrum screens
512x192 pixel
monochrome
Power Requirements:
DVE power supply, 15 V at 1 Amp DC, and with the outside sleeve of the
plug positive and the inside negative. |
