Note that this has to be an 800XL equipped with a 65C816 board, and it is best to have the CPU accelerated. Otherwise this program will not run.

thanks for the information.
I put the cp/m back to the side.

Hi drac030,

 

I have a C128 and have played a little bit wih CP/M on it. But CP/M on the ATARI would be much smarter!

 

My 130XE is equiped with the Rapidus, VBXE and U1MB, that means, ready to go.

 

But I need more detailed instructions to run CP/M on the ATARI and/or Altirra.

 

I really would appreciate if you could publish a kind of "Step by step instruction".

I downloaded the tools and programms on your website, but with no success to run CP/M on Altirra

 

Many thanks

Ok, here you are:

 

a) on real machine: press Invers/Reset, select Preference->Rapidus, Esc, Save & Exit

b) on Altirra: select CPU 65C816, clock speed whatever you like, but I recommend maximum

c) on Altirra: select High memory 4 MB (or 16, whatever)

d) on Altirra: setup Rapidus OS as ROM OS: http://drac030.krap.pl/pl-acc-pliki.php

e) on Altirra: enable VBXE (optional, but recommended)

f) boot SpartaDOS X

g) unpack cpemu06.tar.gz to a convenient place on your HDD. If no HDD, setup some ramdisk and unpack there. IIRC, the files inside occupy 880k unpacked, so it has to be a 1 MB ramdisk. On real Rapidus you may setup a ramdisk in banked 16 MB SD-RAM using RAPIDRD.SYS driver (to be found on Tookit disk -> spartados.com -> Download). TAR.GZ files can be unpacked in one of two ways: using XUNZIP.COM (by Fox&Epi) directly on Atari, or ungzip on PC and untar on Atari using TAR.EXE (-> Toolkit disk).

h) CD CPEMU>SYS[Return]

i) run S_VBXE.SYS (if you have VBXE) or RC_GR8.SYS (if not). Later you may want to get more recent versions of these drivers from the Toolkit disk.

j) CD ..[Return]

k) X CPEMU.EXE CPMSYS.XDI

l) should now load for a while spitting some messages on the screen

m) next the screen shold turn black with green (VBXE) or white (no VBXE) characters, and the following on the top: DLT CP/M 2.2 BIOS REV4 / Hit Return to continue

n) hit Return. This should follow: COPYRIGHT (C) 1979, DIGITAL RESEARCH, and the A> prompt.

o) success.

That is so damn cool!  Question (just for general knowledge).  I have used your excellent Trub Terminal with VBXE to run CP/M on my Indus drive.  This is obviously just a 64kB Z80 implementation.  Does there exist a CP/M which can use > 64kB?

Trub Terminal, as the name says, was written by @trub In CP/Emu implementation I only followed its look and feel, so these two are very similar.

For Atari - none I know of. I know that trub had plans to make a bigger RAM-Charger for Indus/LDW/CA to run CP/M 3 on that, but so far, it seems, nothing has been completed in this respect. Also, making a CP/M port is just the question of perparing proprietary CP/M BIOS for the machine. Now, CP/M 2 BIOS is very simple and there is also a good DRI documentation on how to prepare own version, what functions do, which of them are optional, which are mandatory etc. From what I have seen, CP/M 3 BIOS is much more complicated, it probably requires a banked ROM, and the documentation I have seen was also quite insufficient especially for someone (like me) who has never seen CP/M 3 in action.

Oops - sorry.  I see all of you guys as the genius "polish wonders" providing us with all these goodies.  Please - I do not mean this in any way negative.  I mean it like the "fantastic four" of the Atari folk who formed Activision.

No problem, it is the ambiguity of English "your" which is to blame ("thy" would sometimes be useful). I just wanted to clarify, then, that I am not claiming the authorship of that excellent program (which I also was using while my CA-2001 was in working condition and was able to run Indus CP/M).
