That could help with transferring to e.g. I am planning for a small interfaced that disables and enables ESXDOS by the push of a button. So another interface will not be able to take over. This is because the DivMMC copies the 48 BASIC ROM into its own RAM and keeps that paged in at all time. The DivMMC and many other interfaces won’t work with Interface1/Microdrive, PlusD, Disciple, Multiface or other interfaces that have their own ROM. Not sure what the possibilities are with that, probably no +3 floppy disk features.Īnd that customized ROM won’t be legal to distribute with DivMMC interfaces, so end-user only. I read that there is a customized 128 BASIC ROM that can be activated with the ESXDOS 0.8.6 RC1 release. Since there isn’t much memory space for the ESXDOS developers to work with, it’s not easy or maybe simply impossible to add support for these ROMs. The 128 and +3 BASIC ROMs have completely different entrance points for routines compared to the 48 BASIC ROM.

You can now assemble a complete and 100% compatible ZX Spectrum 128K clone yourself! ZX Spectrum fans continued on this development which resulted in the design that is now known as the ‘Harlequin Superfo’, with 128K versions like the Harlequin rev 2D. Ī couple of years ago, Chris Smith reverse engineered the ZX Spectrum ULA (you can obtain the ZX Spectrum ULA Book to read about that).Ĭhris also developed the original Harlequin 48K: a ZX Spectrum clone based on parts that replace the ULA, so no ULA is needed. We successfully tested using a ZX Spectrum 48K ROM in a Harlequin 128 kit: all games run completely fine. Want to build your own completely compatible ZX Spectrum ‘Toast Rack’?
