There's one on eBay in Germany…

I don't think DBuG has tested his already?

Actually if I trust the schematics the -12V comes from the PSU *after* the first 1000.
And yes, these old power supplies can be nasty.

Although, in the case of peripherals using the same IO they will end up having trouble on the data bus anyway, but yeah…

We should to use open collector/drain or Tri-state outputs on /MAP, /ROMDIS, /IRQ, /I/O_CTRL and /RESET lines. Open-collector and tri-state are not the same. Open-collector basically creates an AND gate with all participating outputs, so any one setting it to 0 will get a 0 on the line. Tri-state i...

My ORIC-1 has a:
HCS 10017 | CDI-7C | 8316

My own Atmos:
HCS 10017 | CDI/8F | 8409

For the other two Atmos, one was never open and the other one:
HCS 10017 | CDI/8F | 8405

Ok, checking on RS-online, the lowest threshold voltage available for shottky diodes seems to be 240mV. Depending on the internal transistor voltage drop it might work.

<big voice> Are you telling me when I'm not around people design electronics without caring about open collector lines ? </big voice> Joking, you can't know everything, these kind of things are usually taught during several years at engineering school… Putting diodes should work, as long as the inte...

There's an attempt at Seilebost's site (scroll down) http://passionoric.free.fr/eng/oric.htm It's already a nice effort, but yeah something more up to date would be cool with all the new hardware around :) I sent a mail asking for permission to reuse but never got any reply. It's not like it's much...

Truth be told, I had to base the depth of the case on an educated guess as I didn’t have the SD card module at hand at the time I was modeling the case. Hence, it’s protruding. Also, in hindsight, I did realize it would’ve made more sense to put the whole card the other way around with the connecto...

Doesn't it have a cut on the bottom for the EXP cable? Why is it getting out from drive2 hole? :-p

You can find schematics here . Note the power connector has pins drawn not in order. And also they labelled it +5 and +12 but it's wrong as well. The power brick itself claims to be 8V and 15V, although it's actually quite more when measured. This is because the regulators are inside the Jasmin, so ...

You know there are black versions of the HE10

I'm still not too fond of 3D printing for such cases but I must admit it looks way better than the Cumulus already!
But why put the SD slot at the bottom and not on the top part (at the red-black junction)?
On the other end I the blue SD part protruding from the Cumulus doesn't look that nice either…

With 3 hours and 30min left I and my machines can still wish you a Happy New Year!

Just saw one in GB on eBay if anyone is interested.
