Wow...absolutely fantastic idea... :excited:

Over the last few weeks, I've finally managed to make time to go through my Atari collection & see what state things are in.

From memory, the hoard comprises
1 x Falcon - internal HDD failed
3 x 1040 STFs: all 3 have red LEDs, two with 1024k & TOS 1.00, other one (my original 1987 purchase) is 4096k & TOS 1.04
2 x STEs (one is 4096k with dual TOS 1.6x/2.06)
5 x STFMs in various states (including one 520 with S/S floppy): one only boots with no floppy connected, another only shows the white border & black centre

So, at least 2 need some attention so I for one would definitely be interested in the super diag cart (or whatever name we are going to give it).

Having realised quite how many working boxes I had, my first thought was to see how many could run as a MIDI Maze multiplayer game (I remember those ninjas as being absolutely lethal).

How sad am I :-D
:lol:

These multi-carts are not anything new, theres a few people been making various types for a while now. Though I wanted to do my own version and add in the stuff which is useful for me as well. So adding in YAART and GB6 plus the Atari diagnostic ROM's make it my ultimate debugging tool.

It would have been nice to have had Diagrom on there as well, though IIRC the whole thing is pretty big, maybe 1MB mark. Though there isn't any reason a second board can't be used with that chip anyway.

Some time ago I was asking about possibility of preparing ROM versions of YAART and SysInfo, but with no response. I only know, that it is impossible to just put an PRG file on a ROM.

Version 8..

Hard to physically get it all to fit and route in just 2 layers... So its a bit messy, but its as good as it can be without spending ages on it all again.

So hacked up another jumper header which can link A15 to the ROM, or can be switched HI or LOW to select a "sub bank" for the 2 versions of YAART.

I half thought a row of DIP switches would be nice, but the ones I used in the past are not very strong , or take up a lot of space. Even so, I don't think its a good idea since with DIP switches they can only have ON/OFF, I need to isolate signals as well, So it would take more switches to isolate or break connections.. but i fear it may well end up shorting out A15 if the wrong combo is selected, so I am not going to think about it anymore..

With the jumpers, its physically impossible to short anything out with the jumper links with how they are all arranged. They may look a bit messy, but again, layout and routing is a issue, but also its done like that to prevent any mishaps.

Atarian Computing has put together a tool set to do just that. GB6 is now a PRG on the cartridge.

I never thought about sysinfo.. but there isn't any room left in this particular ROM. I guess I second ROM could be done with Diagrom and some other stuff like sysinfo.

It may be worth doing a second ROM just for general utils rather than diagnostics. Things like sys_info, FCOPYIII... no idea what else be useful... I dont use many apps past GB6 and FCOPY personally..

Another thought I just had about GB6.. it needs the desktop.inf files on there to boot to medium res...

These are the 2 files I used.. newdesk.inf and desktop.inf.

Of course the A:\ paths will need to be altered to c:\

Then GB6 should auto boot from medium res desktop and auto load GB6... With it being the only app there, it be better to auto boot it anyway.

K, here's a very alpha GUI version of my Powershell script. Make sure you have the files to be converted in the same directory as the executable.

You can select either 64KB or 128KB. I have not coded any safeguards if the file is larger than the image you are converting to. Expect crashes. Otherwise it works just fine.

This would only work with a complex ramdisk. I'll see if there is another way to autoboot.
