What is a benefit of using pico instead regular power supply one?

Not much really. I'm just find using the back power output connector on the pico to power my PAK/FRAK/etc is convenient.

Re: Pico PS load requirement

I use a pico in my Falcon and one of my STs and they work fine without 3.3V being used.

Here's the one in my ST for example.

Re: FRAK/2 Build and Install Project

Finishing up the changes recommended by Holger, there is a resistor to replace and a new GAL set to install on the FRAK/2. I'll also populate 2 ICs and the 6 jumpers which determine the FRAK's operating state. frak_partsb.jpg After putting the everything in place, the FRAK/2 is getting close to comp...

Re: FRAK/2 Build and Install Project

good work, nice ... Simm sockets with metal clips are better. Mine is broken when I change a simm. Thanks, yes, I also wish had the sockets with the metal clips, but these plastic ones should be ok if I don't change the simms in and out too much. Moving on with the changes Holger has been working w...

Re: Interesting Atari Computer from Germany

I wouldn’t be surprised if the 5-pin DIN has been wired to carry audio out of the system, should be possible to tell by seeing where the cables connect to. Steve I traced out the connections somewhat. The 5 pin DIN only has these signals connected to it. ground composite video/sync (ST mainboard ou...

Re: Interesting Atari Computer from Germany

Finally, just a couple more boards. First there is a asci<->scsi board. st-computer_asci.jpg After that there is a little perf board which seems to mainly route some power around but also the blue/black wires are for the reset signal.

Re: Interesting Atari Computer from Germany

Yes, it was the only thing connected on the asci bus. I had the jumper block open for id 0. I reconnected the original half-height drive which is a ST-1096N with id 0 and it booted fine. I might take a close look at the circuit board underneath the ST-251N drive. Maybe the trip overseas stressed a s...

Re: Interesting Atari Computer from Germany

I wanted to try to boot the hard drive even though the odds were that it wouldn't work. The drive is a 40MB Seagate ST-251N. It is 50pin scsi with auto-termination.

Re: ST as a flowerpot

Lol, the responses made me wonder what I was missing. I just see a Atari case re-purposed into something decorative. I figured the computer inside was not there anymore. So I went to the twitter page and sure enough, it's just someone decorating her house with the case. I think it looks good and she...

Re: Interesting Atari Computer from Germany

Oh thanks, that is good to know. I looked at the pcbs again and can't tell if it is Harry-O or Happy-O. The stenciling isn't real clear. I know those parts are from some little kit because the keyboard extender, floppy, and serial/parallel pcbs all have the same yellow stenciling with the Harry-O Co...

Re: Interesting Atari Computer from Germany

Couldn't help tearing it down to check out what's in there. I took out the scsi drive first and gently placed it aside. I'm hoping it will spin up, but probably not due to its age and shipping from Germany. st_computer_teardown_hdd.jpg Then I took out the drive carrier to expose the mainboard. st_co...

Re: Interesting Atari Computer from Germany

Thanks, yes, several of the small pcbs are printed and professionally made.

I'm thinking this was either a kit that was sold to recase a 520ST or an after-market seller was selling recased computers. It's interesting for sure.

It is built like a tank. With the cover off you can see the huge hard drive inside.

Interesting Atari Computer from Germany

I found this computer on the German ebay. What interested me was that the TOS screenshot in the ebay listing was 1985 so I knew it wasn't a megaST mainboard in it. Since I was looking for a desktop case for my PAK68 system I figured this might be big enough if it had a original ST mainboard in it. W...

Continuing to work with Holger on the GND patches. This time on the FRAK/2 board itself. Nothing tricky here. Just beefing up the GND profile through some patch wires. One resistor was removed and a couple of capacitors added per Holger's recommendation. Hopefully this completes the GND patching. :c...
