Like 4MB RAM and 21MHz CPU (switchable to 3.5MHz). Also, I am able to write operating system to make use of such hardware - loading "*.TAP" and "*.Z80" files, emulating some disk extentions (TR-DOS, DISCiPLE, +D, Interface 1, TOS), extending BASIC syntax, etc. > The question is - is there any point pursuing it? If it was not only ZX128 - yes. Look at my mail list - "http://www.egroups.com/messages/zxvgs";, perhaps you find some inspirations. > It wouldn't be compatible with the +2a/+3. That's OK.

To have disk interface and hardware multicolor screen mode, for egzample. > If this came in 1991, I loved it.

But from my point of view, I prefer to hear sound generated by AY-3-8912 in real time than any emulation or record of it.

Yes, but this divides users to two ghettos. In one are ZX128 users and in second SAM users. None of SAM users will write a new program working ZX128, and SAM users must convert ZX128 programs to SAM. Each user group can find the other one as worser. Having ZX128 compatibility SAM users could make some programs useable on ZX128 and cooperation could be closer. (Please forgive the simplification.)

Existing one. Existing hardware! (I know about exceptions like SPEC256, but not much of them are there.) > This is like making a new human.

But I can faster solder e.g. 24E64 chip (8kB IIC memory) than you write and test emulation of it. > You'd better stop saying original hardware is better than > emulation.

However emulation usually follows hardware solutions... > Our technology isn't good enough to make software humans, so > we try to make at least software Sams :))) Software humans are not possible due to lack of the Aumakua equivalent. ;) David L wrote: > Personally, I'd rather see a nice k/b interface :) Why not make them together?
