Thank you so much! I'll try it out tomorrow. What address is your driver configured to use (in autoexec.bat)?

 

I don't believe that's what those boxes are for. In those pictures you posted, those boxes look like standalone 68000 ICE units, similar to the ZAX unit. Those 64-pin connectors on the front would connect directly to the 64-pin socket a regular M68000 unit would normally connect to, or a 65816 processor in the case of that one particular unit. The SNASM2 card is no doubt compatible with these standalone boxes as well, but they're separate and distinct units from the Cross Products MegaCD dev unit.

 

It was just the default settings the install threw at me, 390 comes to mind?
Hmm... and whoops. That Disk on Module isn't ever going to work again... the power cable got so hot it melted the insulating plastic.
I've been meaning to fix that connection...

It might also be something to do with the order I installed the disks. Sega-CD SNASM, SNServer then the Sega 32X disks.
Perhaps the Sega 32X disks had something updated compared with the Sega-CD SNASM?
I really need to dedicate a hard drive to just that. Good to see that Windows 3.11 (Not for Workgroups) works on a PIII 800MHz too!

 

Just thought I'd pop up a video of how I have mine connected up, hope it can be of some use.
Fingers crossed you have some luck shortly! :encouragement:
Let me know if there's anything else I can do to help!



Edit: Managed to hook up the DoM (Those things are indestructible!) and imaged it.
Which led me to the autoexec.bat file, which led to WHAM!
C:\SNASM2\SCSILINK 390

Address is 390 for me and was what Jackhead had set as well on his system...
I'd imaged his hard drive onto the flash drive too but wanted to start fresh everything was German!
Bratwurst this, fussgangerzone that! :wink-new: Mein Deutsche ist sehr limited!
Anyway... Good luck! :victorious:

 

Thanks for the video, nice to see one working! I've tried identical DIP settings and card address, but still no luck. Here's where I'm at: Apologies for the muffled voice and lack of enthusiasm, I have a cold coming

 

Oh I hate it when colds appear, it's usually when I decide to document a whole bunch of things and want to do videos too...

Does the dev unit itself work OK with Mega Drive games and Mega-CD games?
And were you running in pure DOS 6.22?

Short of that these are some last ditch ideas;
1. Check the fuse (Is the fuse for the entire card or just the connector)
2. Reseat all the chips on the board (if they are socketed like mine).
3. How much power are you feeding into the dev unit? I've only for ~2.2A, but it might require 3A unless the manual is lying...
4. I'll think of more, keep bouncing ideas around!

 

I'm running whatever DOS is underneath Windows 95, I'll try an older version. I believe the fuse has its own test after the Card Settings test has passed. It's transparent anyway, and looks fine. I'll try reseating the chips. Just out of interest, does the driver load fine even without the MegaCD connected?

 

The power supply is whatever my retail Genesis came with, the label showing the amps is missing but the unit plays Genesis carts and SegaCD games fine with it. I'd still expect the driver to install (or at least get further than the self tests) even without the MegaCD hooked up anyway, so at the moment I'm just pointing fingers at the card and host PC. No luck with various MSDOS versions, or reseating the chips. Apart from trying a different motherboard (it could take me a while to get hold of one) I'm all out of ideas. I really really hope my card isn't dud, it's about the rarest item I own

 

I'm completely stumped.

Does anyone in the UK have a working setup? I'd be willing to post my SNASM2 card to someone to give it a try with their equipment. I'm desperate at this point

Another thought running through my head is to try replacing the two capacitors on the card.

 

Sending the card to RJ wouldnt cost much.

 

I suppose not. RetroJunkie, would you be up for me sending you my card?

 

Hello! Sorry about the lack of replies, real life has been barging in and trying to cease my internet and fiddling-with-old-things time.
If you'd like me to give it a test that's no problem I guess! I've noticed the post is pretty darned quick between the UK and here as of late too.
Just poking my XRGB I picked up off Yakumo... I know the thread is around here somewhere! :dejection:
Must be because we are part of the colony and trusted, right? I mean I did steal that loaf of bread... but sending me to a desert island? Geez! Talk about overkill!

Oh all the chips are socketed too. I could easily swap them around easily to see if there's a dud chip on there!

 

Brilliant! Cheers RJ, I'm very grateful

I'll PM you later for an address, etc.

 

Sounds like a plan! I do tend to watch the PMs more than subscriptions... now that I am subscribed to almost every thread.
Watching... waiting... oh and a happy 100th post too! :encouragement:

 

Woooo! Well spotted

I'll have a celebratory pie at work for lunch.

 

Stop! Hammer ti... hang on... Could it be your SCSI cable perhaps?

Edit: Seconds after posting RetroJunkie realises that the card should still initialise and hits his forehead against the desk.

 

It was a cheap cable, and there was nothing "SCSI" about it on the label, it just has the correct amount of pins either end. But yes, I would certainly expect the card to initialise correctly with nothing plugged in, and get at least as far as the SCSI Link test.

What happens if you unplug the cable and try initialising the card?

I still haven't sent that PM, I'll do it on my lunch break...

 

I dont understand why you guys try this with a P2 board. Remember me on getting a h2500 working with 5 different P2 boards. At the end the AGP card made anything bad.
Use a 486er with a real 6.22 only, and anything will be fine. My cable cost 5€ on ebay, well retros cable now . But my experience with using that old hardware is, use correct boards/chipsets and so.
Its not only the ISA slot.
