40/44 PIN IDE and 68K Expansion

Do I have this correct?  The 40 PIN IDE is now gone?  I was shopping for cables, did some double checking, and discovered no 40 PIN IDE connector on the drawing at EXTERNAL LINK 
I was hoping to be able to use a CD Rom on this connector.

As for the 44 pin connector, how much power can it supply, or should I plan to provide power to the connected device desperately?  Looking at using a M.2 SSD using an M.2 to IDE adapter I found.

Lastly, as a curiosity, how does one interface with the 68k expansion?

My recommendation is to use the V4 with CF adapter and CF card.

You can still connect 40pin drives. On ebay there's 40-44 pin adapters specially for Amiga. But you still need to provide power.
 
  I have one here, not used, for when I get V1200.

I would not recommend to do this.
The 40pin header was removed to "protect" people from accidently creating short circuits and other stuff which could fry their boards.
So this was done with the intention to protect people as there are risks.

I'm sorry but that's absurd. Plugging in IDE drives isn't difficult. Everyone had to do it for 20 years, amiga people still do it today.

You might as well remove all headers, and have us safely use vampire in our imaginations.

I agree with the decision, just wish I knew before I purchased a Checkmate that this was going to happen.  Such is life, I probably missed the news.

As we know, connecting slower IDE devices onto an IDE bus with faster devices makes the faster devices run at the speed of the slower device.  So I want to avoid that.

I don't really need a CD-ROM, just had the intention originally to do so.  I have T-Zero on CD, as well as a few others, and would like to use it, hopefully with the included CDDA tracks.  Anyway, Not a big deal.

The M.2 drive I'm going to attempt, under worst case scenario while writing, will consume about 600ma of current, 5ma idle.  I suspect that if the IDE interface is built to specification, this shouldn't be a problem, but I think only the Vampire team knows this, and what the overall drain on the power supply is under max load and typical configuration.

But this is not the topic.

We spoke here about CDROM drives ... and those need extra power.
With PSU voltages like 12V.
And adding a 2nd PSU with different voltages into 1 system can lead to frying the system if you make a mistake.
This does not mean everyone will fry his systems
but there is an added risk for this.

What kind of stats from sysinfo do you get with yours Tim. ;)

  There isn't any risk at all.
 
  Really it's a simple thing, IDE cable between vampire and IDE drive, PSU cable to drive. How does 12v go to vampire? It doesn't, unless the drive is in water.

I'm speculating, but it appears that the decision to remove the 40 pin IDE may have a little to do with cost and safety and more to do with philosophy.  This is supposed to be a standalone unit, and to provide an IDE connection that requires a separate 12v power source to use contradicts this philosophy and doesn't make sense.  I guarantee that someone will manage to back-feed 12v on the 5v 44-pin power also.  I also suspect that the 40 pin IDE wasn't on a separate IDE channel, and so of this was the case, there is no benefit whatsoever for it's existence.

I don't know.  It's all speculation until someone explains it.  Regardless, I'm good with it.

    Exactly why we need standard mighty ATX PSU in next Vamp edit, it is small but desktop system - and so little phone like power on small voltage might be industrial upper hand, but is minus for desktop use. Too bad, my DVD RW is gone, will have to prepare ISO files :)
   
  In next edition,  Alongside classic PSU, return 2nd IDE channel and 2nd connector :)

  Do we have nuff power for classic IDE HDD / SATA2IDE SSD (I would use real big one, not M2s)? I can live with cards alone, but feeling would be its highly integrated toy, altough SD performance is nice and you always get max transfer rates with cards.

Sysinfo is irrelevant. You just need to know it's a 1GHz ASIC with 2GB RAM and a 512GB SSD.

  I am with Yoda on this: Try not. Do. Or do not. There is no try.
 
  On your argument, 12V not being connected to Vampire... will you be using one psu offering 5V and 12V or will you be having two psu? Or even two sources of 5V? Both currents will be connected to the CD-ROM drive. IDE adapters offer voltage input. Quite some sources for the guy new to the area can make mistakes.
 
  Politeness is nothing you get by phrasing “Sorry, but”. Absurd is trying to educate people about their vision.
 
  Have fun.
