Disk drive peripheral for Timex Sinclair machines and CP/M computer. From Wikipedia, the free encyclopedia
The Timex FDD 3000[1] in 1982 was a nearly complete computer by Timex of Portugal.[2] It began its development at Timex Computer Corporation in the U.S., but it was at Timex of Portugal that the work was finished.

The Timex FDD 3000 is an upgraded Timex FDD (sometimes known as the FDD3 because it consisted of three separate boxes: a floppy-disk drive, the controller and the power supply).[3][1][2] The Timex FDD3 was intended as a floppy disk peripheral for the Timex TC 2048 or TC 2068 microcomputers.[3] It usually had 16K RAM and only one 3″ disk drive, but could be upgraded to 64K RAM and a second disk drive, making it capable of running CP/M. Since the controller is electrically compatible with today's disk drives, it is possible to connect a 3.5″/5.25″ disk drive to the Timex FDD3 Controller.
Later, Timex combined the three boxes of the FDD into one big box called the Timex FDD 3000. Timex also added 64K RAM, a second 3″ floppy disk drive and a line in the controller cable to pass the video signal generated by the Timex Terminal 3000 to the back of FDD 3000 box.
The FDD/FDD 3000 can be used as a disk drive peripheral or as a CP/M computer.
To use the FDD or FDD 3000 with a computer, an interface module is needed. It's called Timex Interface (TI) and contains the FDD/FDD 3000 initialization code in a ROM.
Because of the differences between the TC 2048 and the TC 2068 ROMs, there are two TI versions: an all-black version for ZX Spectrum & TC 2048 and a black with silver reset button for T/S & TC 2068. The TI TC 2048 version can be used with T/S & TC 2068 plus emulator cartridge (it has to be a "bootable" cartridge as you cannot type OUT 244,3 because the computer will crash).
Zebra Systems Inc.[5] sold an all-silver TI. There is a TI ROM version that will work with ZX Spectrum 128.
