Spectrum 128 was designed in the UK but first made in Spain by Investronica. Sinclair didn''t sell it in the UK until 1986 because of an agreement with Lasky''s to shift all the remaining rubber and plus models first. However you could get Spanish 128s (which included a external numeric keypad) at all the major retailers in the UK from about August 1985. They cost about 200 quid - about the same as a Commodore 64 at the time.

The 128 is a 48K system, the 80Kb above ramtop could be used as a ramdrive in BASIC, or swapped in 16K at a time in MC.

Spectrum 128K memory was not organized in two blocks. It was top 16K of the regular addressable 64K that was used to switch into additional 64K of memory.

Does anyone know of a single chip spectrum (ON FPGA) like the Altera DE0 board ?? or has anyone made a new speccy running on the eZ80. The eZ80 runs 50 times faster than a 4MHz Z80A !!!!!!

It would be a great project.... or even make a Sam Coupe running on an eZ80 !!

Does anyone know of a tape database for speccy software that I can download for free ?? I''m looking for audio files not digital ones, as I''m meaning to put the software onto floppy 3" disks !!

If anyone knows please post a message !!
