Re: Editing a message

I'm not upset about the change, but I do wish we could edit our posts. For example, I updated my Panther/2 thread from 5 years ago since I finally finished the project. Turns out all the linked pictures from 2014 were gone. So I updated them with local copies instead of an image hosting site. Wouldn...

Re: Installing the PAK68/3

Thank you for checking, that's good to know. I am using the F-types and I don't have any freezing or screen corruption.

Awesome! Yes, if you get to try the F373 we can know if the problem comes back with them.

Re: Installing the PAK68/3

Thanks Arne for the information. Sounds like you are having issues with 68030 mode also. @Gaiyan, your suggestion about the hdd got me thinking. I hooked up an ultrasatan and a spare SD card. ultrasatan.png As I suspected, the drive C wasn't even recognized. I added the drive C icon, but there is no...

Re: Installing the PAK68/3

I have a Mega ST1 Board with 4MB ST Ram and a Lightning ST, PuPla/2, PAK68/3-030, FRAK/2 und a Panther/2 Adapter with MACH64 and NE2000 card. The floppy is mostly working fine but sometimes the floppy are not working. I have to reboot. It is normal, I think ... My MST Mainboard has 4,7k and 2,2k Pu...

Re: Installing the PAK68/3

Well, the PAK boots to the desktop, the memory test passes and everything functions at the desktop like windows, menus, icons. But without the drive working, I can't run benchmarks or sysinfo and I can't do any burn-in to test stability under load so to speak. So really can't progress with the proje...

Re: Installing the PAK68/3

Ok, I was thinking about my floppy drive issue. Since it only happens in 68030 mode I started considering timing issues and the faster clock. The manual talks about clock buffering being able to fix some dma problems. Also mentions clock buffering as required when an fpu is equipped which I have. cl...

Re: Installing the PAK68/3

Ok, changed out the DMA controller and the drives are back on the desktop. :angel: The good news is the drive works when the PAK is used in alternate operating mode with the 68000. The bad news is it still doesn't work in 68030 mode. It makes a grinding sound trying to access the drive before throwi...

Re: Installing the PAK68/3

Uh oh, I think I killed something. I replaced all the remaining chips on the PAK except the Cache RAM and the floppy still wouldn't read. So then I decided to do the pull-up fix for the floppy data lines. I used a 4.7k resistor network because it's what I had handy. But I made a mistake. See the pic...

Re: Installing the PAK68/3

I have a 10k bus resistor array on the data lines on the 1772. But I had that installed before i got my PAK installed so never thought about that. Maybe try that? Interesting idea. The manual mentions possible problems with the floppy, but says the patched PAK-TOS has corrected the error. But that ...

Re: Installing the PAK68/3

Well, the PAK was apparently damaged by the previous owner as I've had to replace quite a number of components. But it is booting now and stable, but there is still a problem. The floppy drive will not read. It displays an error message when trying to open the A: drive. The error is the same with th...

Re: Installing the PAK68/3

After double-checking all connections I turned on the power to the ST. There was no smoke or loud pops so that was good :D but the screen just stayed white. It never made it to the desktop and there was no PAK logo. I felt the chips on the PAK and nothing was hot, but I turned off the computer after...

Just something to note. manual_markup.png manual_b_markup.png I needed to update a couple of the GALs (U4 and U5). Looking...

Re: Installing the PAK68/3

Oh yeah for sure I'll definitely hook up good grounds! As with the 5V, the GND pads are also pristine. So there are two options: 1) The PAK was never installed. or 2) The previous owner never hooked up the PAK's VCC and GND and just used the CPU socket connection for them. Either way I'm going to us...

Re: Installing the PAK68/3

Thinking about power requirements and how I'm going to hook up to the power connections. The strange thing is I took a look under the microscope and neither power hookup has ever been used. Pads are brand new. pak_power.png pak_power_b.png So can the PAK be operated under mainboard power only? It se...

Re: Dust cover for Atari.

The clear plastic ones are kind of nice but just like most dust covers they don't cover devices plugged into the cartridge port such as the Midex or Unitor. Yes, those are the ones I use. I have 3 of them, for my Falcon, STE and 130XE. They are nice because you can still see the computer and they h...

Re: Installing the PAK68/3

Looking at the RAM on the board. Seems the Tag-RAM U18 and U19 are 25ns parts. The Parts List calls for 20ns chips. Might not make too much of a difference until I get to higher speeds, but it's something to note. Also the Cache-RAM chips U14-U17 are under the ROM chips. These look like they are 15n...

Re: Installing the PAK68/3

The solder pads are clean and nothing has ever been soldered there. I'll probably need to solder a component ...

Forgot one point on the motherboard prep. The line drivers/buffers on the Marpet extension are 74HC244E type. Being CMOS, I think they should be fast enough.

Re: Installing the PAK68/3

I will be using an original ST for this upgrade. There a few things to do to prepare the motherboard for the PAK. These are recommended steps from the PAK manual, mainly if higher speeds are desired. Since I am going to shoot for 50MHz eventually, it probably would be best to get the motherboard in ...

So time to hook it up and see what happens. First I set up my test ST which I had used for testing the VoFa adapter. Also downloaded the Panther/2 ET4000 driver from Idek's site and put it on the floppy. Then I plugged in the bus adapter and placed the 68000 on top. step09.png I made a quick power c...
