ZX-Uno

Sorry, I really have been out of the loop. SE Basic IV 4.0 (Anya) is a 32K ROM designed for the Spectrum SE. It is a development of OpenSE Basic 3. It's not quite as compatible but it does have the advantage of offering an 80 column mode. Just enter: MODE 1

Let's see, I think that by now it is more than seen that the ZXU is not squeezed to the fullest or almost. The point is that with all the experience acquired we should move on to an evolution of the plate. It is clear that the 512K does not give more than if, many have the expansion of 2 MB, to cit...

En realidad no es emulación. Es un método para meter la ROM del TS2068 (clon americano legal de spectrum) en un ZX-Uno. The TS2068 emulator is a 32K soft-ROM for the ZX Spectrum SE, dating from 17 years ago. I wrote it with help from Alvin Albrecht. The 2068 has a 24K of ROM, 16K in the HOME bank, ...

Or there's UnoDOS 3 which does everything via dot commands instead of overloading BASIC.

No. Spec256 uses a 64-bit Z80 co-processor and parallel memory to store the images. There isn't physically enough RAM or gates on the FPGA to do it. RAM Access = 17.85ns(SRAM R/W) * 8bytes(64bit) = 142.85ns(CPU R/W) + 142.85ns(Video R) = 285.71ns(3.5MHz CPU Clock) My project Spec256 uses ROM 16K + ...

NextOS supports the esxdos api and dot commands so that's not going away. Because of the mmu, there is likely going to be an allocation map to show which 8k ram pages are available, which will mean loading programs into a scattered memory map could be a thing along with really big dot commands and ...

Is it possible to make something like Spec256 in the ZX-UNO? http://www.emulatronia.com/emusdaqui/spec256/index-eng.htm If yes, we can convert a lot of games. :mrgreen: No. Spec256 uses a 64-bit Z80 co-processor and parallel memory to store the images. There isn't physically enough RAM or gates on ...

Seems all this is moot because esxDOS support is being dropped from the Next.
