Please take a look, idea is to support as much as possible ROMs.
Meanwhile I will work on Erik, I have already booted machine, and have video out work. Need to map ports now.

If you use machine translator on my message, it's might be totally incorrect. So, I said this:

@cr0acker
Idea of MESS is to implement emulation of all machine same are realy bad design, have some bugs in ROM, but idea is to support as much as possible.
@HardWareMan
I agree that it is incompatible code since none of games/applications for Specialist works on it. they are all using direct memory access to write on screen, so in this case when video memory start is on different location it just can't work.

Screen offset = 0x8000 --> Screen width = 512?

@b2m
Looks like you are right. Only command that could display something usefull was D (disassebler) .
And it is shown fine in that mode only, if I put 384 data is missing.
So it looks like hi-res modified model.
Thanks for suggestion.

Все правильно не нужно использовать в эмуляторе ПЗУ от Эрика (кстати не совместимого со Специалистом МХ). Вот можно взять ПЗУ предложенного HardWareMan'ом:

I have used Erik.bin from Shaos and using PDF documentation I was able to make it run fine.
@fifan
Can you please explain more where to map this in Erik memory map.
Since if I place ROMDISK.BIN instead of ROM it can't work.
Guess this is placed as extension but my question where and how to make it book.

I have already used that PDF as guide to make driver.
And Eric boots and I get monitor running fine.
My question is: Is Romdisk.bin you have sent me for Erik ?

I guess not. This ROMDISK.BIN is a image of external ROM disk for NC for Specialist (attached to VV55 - 8255). And this image is NOT BOOTABLE. Here is bootable ROM (and internal ROM disk) for Specialist MX:

@hardwareman
I have booted NC and it works (used only romdisk image).
Are all programs from it working on real machine?
I have error running ED7000.COM,DISS.COM,ASMHQ.COM and ASSM.COM
If you have other rom disks please upload them.
Thanks

Shure, but not under NC. Some of applications must run under old monitor "MAGIC.COM". You must just load this program and then run MAGIC. Then use standard command "G<ADR>". That is my compilation of ROM disk and I did not have enough time to test it.
Well, I have some separate applications, and original NC boot ROM. Man, who did this NC has died (Could be just hearsay. I heard it from the head of radiotech hobby group I used to attend. That's where I was using the "Specialist"), so no possible get more info and apps for NC. But, IMHO, it is the best OS (hm.. not "OS" - it may be called "DOS") fo Specialist MX.
