Thanks, Alastair. Yes, the program can be started manually. I just wanted to say, that this is the only program I saw, that does not auto-start, like all of the the others.
And I noticed, many programs can be launched via "EXEC" without address! They start anyway.

I had not much time, but here is a picture of my little "multi-cartridge production line". As you can see, I ran out of components.

I still have to test the remaining rom images. And I want to try some 16k types. Not done yet.

Hahaha. Cool 8-)

I wish I was organised enough to build more than one thing at a time. :D

I'm sure Rolo won't mind me telling you all this, but we had a little project exchange and so I've been playing with one his multicarts this evening...

What a great bit of kit this is. 32 8k rom files on one cartridge barely any larger than a regular cart, and it works perfectly. Build quality is good - very sturdy; and I have no complaints about its ease of use - you turn the knob, insert the cart and power-up, the little displays confirms which slot you've got selected, and then an exec &hc000 loads your rom.

Some of his game choices are a little dubious but hey. ;) I'm going to get great use out of this, I can tell already.

Congratulations mate - project has turned out very well indeed.

Thanks Rink :oops:

Yes indeed. I'm not through, examining all available roms, so I simply put 32 "random" games on the eproms. I don't know the games, but I noticed, not all games are really, ahhmm, "great" games. I suggest, you simply reprogram the eproms someday (simply eight sequential 8k chunks per eprom).
Maybe it's the best way to adapt the multi-cart to one's personal needs and wishes.

List of roms working on Dragon multi-cartridge

Postby Rolo » Mon Oct 07, 2013 8:27 pm

Roms for use with the Dragon multi-cart and other Dragon cartridge devices

:lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol:

I tested these roms on a Dragon 32 with the multi-cart. There are no special requirements for the multi-cart and these roms should work with any other cartridge device built for the Dragon computer. The "modDragon"-denoted CoCo-roms only were changed to make them compatible with the Dragon, not because of the use with multi-cart. The "modDragon-roms" can be found as attachments of several posts in the Uploads-section.

:!: Some of the CoCo-programs have that joystick-dependent noise, since Dragon Color Basic does not, like CoCo, switch off audio, when it reads the joysticks' axis. In the meantime, I've changed most of them.
-------------------------------
:!: Many of the CoCo roms are NTSC versions. They appear black and white on PAL. Also cross-color is not working on PAL.
-------------------------------
:!: I closed the 8k-list. I modified almost all of the 2k/4k/8k Tandy rom images, where needed. Almost all programs are working. I leave some programs like painting applications, which probably nobody will ever use anymore, these days (If somebody absolutely wants to load one of those programs into the mulit-cart, I can have a look at it). I will check for new roms from time to time.

I uploaded two new patched Tandy roms and one Dragon rom. Check them out at the Upload section.
Have fun,

Dragon multi-cartridge modified for 16k-roms

Postby Rolo » Thu Nov 28, 2013 11:36 pm

In the meantime I modified one my multi-cartridges for the use of 16k roms. This is quite easy to do. I marked the changes with red ovals on the photos below:
multicart16ktop.jpg
Dragon multi-cartridge 16kmod top

multicart16kbottom.jpg
Dragon multi-cartridge 16kmod bottom
multicart16kbottom.jpg (223.8 KiB) Viewed 1328 times

One cartridge now can hold up to sixteen 16k-roms, using four 27C512 eproms. There are not many 16k-roms out there, so this is plenty!
Changes:
    The switch is no longer needed.
    An extra address line must be connected to the cartridge port.
    The same address line must be disconnected from the multi-cart's selection circuit (notice the little drilled hole inside the IC3-socket).
    The jumpers must be set like it is shown on the photograph.
    One additional connection must be made, where the switch was (red wire).
I've already tried a few roms. They are working fine. Unfortunately there is that incompatibility of the keyboard connection of Dragon and CoCo, which is giving me headaches. Changing that in the game roms is quite some work to do and not exactly easy, but I don't want to modify my Dragon's hardware and to rearrange the "PIA lines" or make them switchable.
I appended the names of the tested 16k-roms to the big 8k-list of the other post.
All in all the experiment was a success (I just have to patch another few roms).
