Hello hero her> Have you ever filed a patent (copyright certificate)? :) Ratsuhi, but the boss always received the bonus. :v2_cry; her>; The question is how, for example, to pair the eZ80 Z80 RAM ROM VRAM BaseIO and her> etc. This is not emulated; it must be done in hardware.

Otherwise, from the bush 200% productivity (and her> respectively energy consumption) into the air Ok, I’ll lift part of the veil. There is a controller (100 legs), which becomes between two processors and... generates all the necessary resources for the z80, including real and virtual, about the latter a little later. So, real ports are which immediately go to devices, for example an expansion bus, time-critical treatment or the simplest, but the most important thing is that there are not a bunch of decryptors for each resource. Each device has its own “wire”. :v2_wink2; Now; virtual. The Z80 accesses the ports, let the keyboard, and in responsereceives data that is first scanned by the eZ80 from the ps/2 keyboard or something else which device and places them in the controller. The example given is rough though allowing you to see that you can use all the capabilities of the eZ80 with its i2c, serial ports, etc. Here, however, you can change eZ to ARM, but with these I haven’t worked yet and I would like to have command compatibility. In both cases, it is enough to indicate to the controller the “route” of receiving/sending data and voila. Programming down to BASIC, although it will be useful to have shell. her> And are you going to generate the video output using the process or is it for me her> it was an illusion (misunderstood) Problems only arise in the case of full clock speed on the z80, i.e. 20MZh. In the case of a standard or turbo clock there are no problems. I'm thinking about going to VGA too get. Although, judging by the correctness of the diagram, it will be necessary to hang up a formative video controller, only for the purpose of freeing up resources and systematizing the circuit on "modularity". :v2_finge; I; I don’t intend to intrigue anyone at all, the point is that several times people joined the project and... went into deep infighting with further burial of the project. It seems that with the proper degree of persistence, taking advantage of the end of the session and the beginning of vacation.. You can rush to Moscowand.. buy a screen and a couple of micro devices. I made a small mistake when ordering microcircuits in the planar, and now we need to make adapters.. :v2_cool:
