Hello Andrey
Thank very much you for your thorough explanation. By the way, let me say that your work restoring the source code of the HiTech compiler seems to me awesome!!
I am also interested on UZI180 (among other operating systems), and this source code version of the HiTech compiler.
I am going to receive a P112 board, hopefully in two weeks, or one month, so that is great news for me!! It will include GIDE, a 1.44Mb floppy drive, and a dual CF-IDE adapter.
So I will try to install the last version of UZI180 on it. I would like to help with some of the pending items you have mentioned (some stability issues, an editor, etcetera). Only the future can tell if that is possible for me, specially in the short term, if I will have the sufficient knowledge for it, and also enough spare time.
We can also talk, I suppose better on another thread (so that things are easier to search by theme on this group), about Fuzix. The advantages and drawbacks we see on it.
I hope talking about unix-like operating systems are not considered out of topic for this group, as its name is "comp.os.cpm". Well, I don't know, the thing is that they share the same hardware, so, from that side, it makes sense to talk about software that run on the same common hardware. If necessary, we could move the discussion to other Google groups. I at least know two others: "retro-comp" and "RC2014-Z80".
This question arises for me as I am , in practice, new to this group.
Of course, CP/M also interests me , as it requires so little resources of RAM, and for me has gained more interest recently, as they have appeared , for example, channels in YouTube that not only talk about CP/M, but also are great videos to learn other things, such as assembler for the Z80 , the SPI interface, etcetera. One thing I want to investigate is the capabilities of MP/M for multitasking. In any case , CP/M is also a great place to learn things
One last thing for now, so as not to make this message too long.
In case you haven't see it, let me tell that yesterday I saw at the group "RC2014-Z80" a thread that talks about improvements, made by a member of that group, to the assembler of the Hitech compiler. The thread has the title "Z80AS - new Z80 assembler, compatible with the HiTech tools". In case this interests you. Ummm, I think this person is working with CP/M
So , step by step, I first have to receive the P112 board, and then install the last version of UZI180. Afterwards, I will see if I can help with any pending item you have mentioned.
Regards,
Alvaro Garcia
