Why the divIDE interface?
- small and compact size
- energy savings construction
- works on all types of Spectrums
- cheap
- prepared for the old systems (GDOS, TRDOS) emulation
- suitable for safe system developments
- PC (IDE) devices support
- CF-IDE and SD-IDE devices work without additional power
- no boot needed, firmware could be flashed
- operation system could be changed on-fly (load and flash another one)
- reset resistent system
- 8KB and 16KB paging
- NMI support
- allram mode
- write protect
- automapper enable/disable
- system calls support
Versions and expansions of the divIDE interface
- The original, still in the shop divide.cz.
- DivIDE Plus alias DIWIDE sold by the RWAP. 512KB RAM and ROM expansion.
Please distinguish from the +divide (Disciple and +D compatible operating system).
- 512KB RAM expansion proposed by the author of divIDE. Needs some additional logic chips. No prototype exists, I think.
- Allram mode based on 16KB pages for the old units (till the 2007?). Needs one chip update (RGAL").
- 512KB RAM and 128KB ROM expansion made by Velesoft. Simple, needs some (GAL) chip update and a little wiring.
- Memory interface with MB-02 layout, a separate unit between ZX expansion bus and divIDE. For the full MB-02 compatibily is the Datagear (DMA) interface needed. Proposed by Velesoft.
