kodak80 progress
Re: kodak80 progress
Nice job Kodak80! Nice patches!
Re: kodak80 progress
I have just added the floppy pull-up patch but cannot get the board to recognise my floppy. Have tried both a Gotek and an Epson 308 drive. Any thoughts from those who have the floppy working?

Re: kodak80 progress
Mine sprang into life after the pull-ups on the floppy but I believe @Forgottenmyname had some issues on soldering around the WD1772. I think its the solder not making contact with the pads very well. I have also seen this on my board in several places. Check round the chip and make sure you are getting good contacts.kodak80 wrote: Sun Oct 07, 2018 1:37 am I have just added the floppy pull-up patch but cannot get the board to recognise my floppy.

Re: kodak80 progress
Yeah as Icky said, I had a problem with the 1772. Basically I'd soldered a few of the pins a little too fast, so that the solder had not penetrated properly to the other layers of the board. I only found this out by checking with a multimeter. Might be worth scoping the 1772 as well, to make sure you have all the relevant signals. I used a working ST to compare against.
Also I have TOS 1.04 selected by jumpering the rom jumper.

If it ain't broke, test it to Destruction.

Ah yes - I forgot that one. Good spot.Forgottenmyname wrote: Sun Oct 07, 2018 8:50 am Also I have TOS 1.04 selected by jumpering the rom jumper.
Re: kodak80 progress
OK, thanks for the pointer. Still waiting for my new scope to arrive so will try checking the soldering on the WD1772 socket. My expert mate is also away now for 3 weeks so will be diangosing things on my own. Have been mainly booting into TOS 1.04.
With my 2nd board, I now have it booting to TOS after doing some of the mods.
Still have a few mods to do though.
I also quickly tried my SatanDisk on the 1st board and at one point had it boot and show drive partitions. When I tried opening some folders on one of the drives, the system rebooted and now doesn't seem to see the SatanDisk. Not sure if this corrupted the disk partitions. Need to plug it into an old ST to test if things are corrupted.

BGACK PULL UP FIX: https://www.exxosforum.co.uk/forum/viewt ... =10#p10086
Question for Icky and Forgottenmyname: Just curious, do you have this modification still on your boards?
I note that Exxos advised that this modification is not needed: https://www.exxosforum.co.uk/forum/viewt ... ACK#p10785
Also, with the GLUE modification: https://www.exxosforum.co.uk/forum/viewt ... =30#p10524
When I connect GLUE D0 to RP3 pin 2, the board stops booting and I get a white screen. Any thoughts on why? Both of the tracks have been cut. If I disconnect this 1 bodge wire the board boots to TOS.

Re: kodak80 progress
Hi Kodak, I'm sure I did do this fix but not home right now to verify.
If it ain't broke, test it to Destruction.

Did you cut both tracks on STEP 1? The cut track line is across two tracks on the bottom of the board. One marked in yellow and the other in blue.kodak80 wrote: Mon Oct 08, 2018 9:39 am Also, with the GLUE modification: https://www.exxosforum.co.uk/forum/viewt ... =30#p10524
