I would go with the later firmware though anyway. Previous firmware had known issues which were all fixed in the last version.

OK, TLDR

i've got one of these drives now, which I'm using on a Mega ST. So it comes with the ribbon cable and adaptor to DB19. Is it possible to connect the ribbon cable to the internal ACSI header? Or is an adapter PCB required?

Hi
A quick look at a MST schematic shows it will need an adapter board. If that's something you can do, look at the Db19 pin out for signals - MST schematic

Good luck

Thanks, do you have the pinout for the IDC connector on the board itself? I'll likely make up a cable to interface directly from there, then power it from inside the Mega ST somewhere.

Yes of course. I'm not home during the week. If I get a chance (remember :)), I'll post details over weekend

Cool, thanks, no rush.

Just thought - it's the same as UltraSatan if you can find that

Ok that's even betters I have one of those with their adaptors. I'll just duplicate that then, thank you.

I have 19 of these Atari ST SD hard drives left in stock. I'm not planning on building them again.

They are built up ready to use with DMA cables and SD card.


SHORT TERM OFFER.

If someone buys more than 5 then I will refund 20%.

@exxos - did someone confirm there was no issue with this connected to an STE with a 32MHz accelerator in the end?

I bought one (and have used it on a plain ST thus far...might even get connected to the Mega ST with my ATW800/2 board inside it at some point) but still haven't tried it with the accelerated STE.

Now trying to work out if I can push my birthday & father's day list far enough to take advantage of that special offer...but I suspect I'll get a straight 'No' from my wife & kids... :(
