Modern ZX Spectrum today
This page is about a Speccy for 21st century, enhanced in all important parts like turbo CPU, memory upgrade, DMA, professional PC keyboard, scroll-wheel mouse, ethernet/comms/SPI/I2C, expanded sound (SAA or 2xAY, FM synth, SID), high quality digital display and modern storage device with a PC-compatible DOS.
Forget about old chips, FPGA rulez!
When purchasing a new ZX Spectrum, think about...
- capacity of the FPGA is big enough and the core should be easily expanded
- unified one core, no limited small cores for different peripherals (no fragmented Speccys!)
- all zx-expansion and interfaces combined in one FPGA core, without compatibility issues and without collisions
- implemented interfaces do not cause problems with other connected external interfaces
- all devices can be used, if possible, at once and in parallel
- both west- and east-european hardware is supported (Timex with Pentagon, Radastan with General Sound, DivMMC with Z-Card)
- single peripherals can be easily switched on and off "on the fly"
- whole hardware is linkable with common cheap PC peripherals
A good modern Speccy clone should be able to run all software written for any ZX Spectrum model or a popular clone, it also should support brand new and innovative programs (in recent years coming mainly from East Europe), using advanced hardware like TSFM, GS, ULA+, DivSD or HR(X)C.
After years, most ZX Spectrum followers do not meet abovementioned requirements (sorry, old ZX-Unos and SpecNext users...).
Currently there are only two perspective compact models with common expansions built-in (DivSD, ULA+, Covox+Soundrive, etc.).
