[2019-12-01 19:56:39 CET] <rune> Hello heinz
[2019-12-01 19:56:48 CET] <rune> Ws
[2019-12-01 19:57:06 CET] <rune> Was fixing the mess I made of the tracks in Kicad
[2019-12-01 19:57:35 CET] <rune> I think my problem is with Z5-6/z7-8 tracks 20/21
[2019-12-01 19:57:53 CET] <rune> IS there any cuts needed for anything here
[2019-12-01 20:03:02 CET] <heinz> Hello Dave, I also think thaat z7-8 is not correct. 
[2019-12-01 20:03:32 CET] <rune> Id agree, but Ine checked until Im blue in the face.Cant see anything
[2019-12-01 20:03:49 CET] <heinz> I had the same problem and the reason was the missing power at Z30.
[2019-12-01 20:04:00 CET] <rune> On my schema in Kicad, I had 20/21 connected to 21/20
[2019-12-01 20:04:17 CET] <rune> but I may have done that after you pointed out the error
[2019-12-01 20:04:29 CET] <rune> I have power and ground to Z30
[2019-12-01 20:04:37 CET] <rune> Changed the IC 3 times
[2019-12-01 20:05:23 CET] <heinz> What do you mean with 20/21 to 21/20?
[2019-12-01 20:05:56 CET] <rune> Z7/20 went to z5/21 z7/21 went to z5/20
[2019-12-01 20:06:08 CET] <rune> But that may have been an error intorduced later.
[2019-12-01 20:06:16 CET] <rune> On my board its 20-20 21-21
[2019-12-01 20:06:44 CET] <rune> Are any tracks needing cut on Z506 or 7-8
[2019-12-01 20:07:20 CET] <heinz> ok, 20-20. Then check 20Z7 to 2Z30
[2019-12-01 20:08:04 CET] <heinz> And 21Z7 to 1Z30.
[2019-12-01 20:08:40 CET] <rune> Just checked continuity - all OK
[2019-12-01 20:09:12 CET] <heinz> I will have a look to my board for cuts.  Wait.
[2019-12-01 20:11:10 CET] <heinz> No cuts. Did you connect 19Z5 with GND?
[2019-12-01 20:11:32 CET] <rune> yes
[2019-12-01 20:11:53 CET] <heinz> Let us have a look to 18Z5.
[2019-12-01 20:12:03 CET] <heinz>  Where does it go?
[2019-12-01 20:12:32 CET] <heinz> to 1Z24?
[2019-12-01 20:12:39 CET] <rune> z23/4
[2019-12-01 20:13:15 CET] <heinz> Yes, it is the same.
[2019-12-01 20:13:41 CET] <rune> then z24/1
[2019-12-01 20:14:37 CET] <rune> Its very strange. I need to triple check the componnents
[2019-12-01 20:15:26 CET] <heinz> There was a missing connection Z27/10 to Z24/13.
[2019-12-01 20:15:41 CET] <heinz> sorry, to Z27/13
[2019-12-01 20:16:19 CET] <heinz> But my board runs also whithout this connection.-
[2019-12-01 20:16:48 CET] <rune> I have connected it.
[2019-12-01 20:17:32 CET] <rune> hold on,,,,,
[2019-12-01 20:18:20 CET] <rune> I may have connected on wrong side
[2019-12-01 20:18:54 CET] <heinz> at Z27?
[2019-12-01 20:19:07 CET] <rune> ive connected pin 1 an pin4
[2019-12-01 20:20:27 CET] <heinz> even Z27/1 and Z27/4 should be connected to +5V.
[2019-12-01 20:20:58 CET] <rune> Yes it is. So I need another fron 10 to 13?
[2019-12-01 20:21:24 CET] <heinz> Z27/4 was GND before, this is wrong. No SAVE in this case. 
[2019-12-01 20:22:04 CET] <heinz> Yes, but I did not have one and it works. But there should be a connection. Definitely.
[2019-12-01 20:22:53 CET] <rune> No SAVE wouldnt  cause the corrupt characters?
[2019-12-01 20:23:14 CET] <heinz> No. No SAVE was a different problem.
[2019-12-01 20:23:54 CET] <rune> Are you sure its 10-13? The scvhema seems to show 9-13
[2019-12-01 20:24:40 CET] <rune> no, got the wrong IC
[2019-12-01 20:25:05 CET] <heinz> Z27=LS74
[2019-12-01 20:26:40 CET] <rune> OK, my pin 10 isnt connected. I'll do that and see how it goes
[2019-12-01 20:27:03 CET] <heinz> I think there will be no difference as before.
[2019-12-01 20:27:14 CET] <heinz> But it should be connected.
[2019-12-01 20:27:17 CET] <rune> Need to wait until tomorrow though. Too dark and cold
[2019-12-01 20:27:33 CET] <heinz> Should we continue?
[2019-12-01 20:27:45 CET] <rune> yes, talk about USB scopes
[2019-12-01 20:28:15 CET] <rune> I'll send a pic of the back of my board. Maybe you will spot what I cant
[2019-12-01 20:28:15 CET] * heinz quit (CGI:IRC (EOF))
[2019-12-01 20:28:23 CET] * heinz joined
[2019-12-01 20:28:41 CET] <heinz> I had a problem. Wrong key.
[2019-12-01 20:28:55 CET] <heinz> Are you there?
[2019-12-01 20:28:55 CET] <rune> Are you on the Raspi?
[2019-12-01 20:29:04 CET] <heinz> No, I am on PC.
[2019-12-01 20:29:23 CET] <heinz> Could we continue with the board or is it to cold?
[2019-12-01 20:29:41 CET] <heinz> Take the board and go in a heated room.
[2019-12-01 20:29:52 CET] <rune> Its too cold for me to go make any changes. Im happy to test/check anything you suggest
[2019-12-01 20:30:05 CET] <heinz> Changes are not needed.
[2019-12-01 20:30:09 CET] <rune> Im in a heated room. The soldering iron is in my shed
[2019-12-01 20:30:20 CET] <heinz> Just measuremants for connection. tn
[2019-12-01 20:30:28 CET] <heinz> Or a good magnifier glass.
[2019-12-01 20:30:31 CET] <rune> I have a multimeter
[2019-12-01 20:30:38 CET] <heinz> This is enough. 
[2019-12-01 20:30:47 CET] <heinz> Are you in a warm room now?
[2019-12-01 20:30:47 CET] <rune> The magnifying glass is out oin the shed too
[2019-12-01 20:30:52 CET] <rune> Yes
[2019-12-01 20:31:12 CET] <heinz> Firsat let us have a look onto the board for cuts.
[2019-12-01 20:31:27 CET] <rune> ok
[2019-12-01 20:31:30 CET] <heinz> Starting at the top side from left to right.
[2019-12-01 20:31:52 CET] <heinz> I have two cuts left of Z3-4.
[2019-12-01 20:32:18 CET] <rune> OK, I have 1
[2019-12-01 20:32:41 CET] <heinz> Going to the ROM or to the Z3-4?
[2019-12-01 20:33:10 CET] <rune> At Pin 19 A10, which I now soldered to the GND
[2019-12-01 20:33:55 CET] <rune> Nothing else cut
[2019-12-01 20:34:22 CET] <heinz> I have a second one coming from the ROM.
[2019-12-01 20:34:45 CET] <rune> What track?
[2019-12-01 20:34:46 CET] <heinz> Might be you have that at another oplace.
[2019-12-01 20:34:51 CET] <heinz> place
[2019-12-01 20:35:15 CET] <heinz> Next cut left of Z18
[2019-12-01 20:36:49 CET] <rune> No, I dont see a cut there
[2019-12-01 20:37:35 CET] <heinz> I will take your picture of the board and mark all of my cuts. Then you can track them and compare with your cuts.
[2019-12-01 20:38:06 CET] <rune> Thats a great idea. I only have 2 cuts on my board. Cant see second one just now
[2019-12-01 20:38:15 CET] <heinz> Because you could have them at a different place - or forgotten.
[2019-12-01 20:38:26 CET] <rune> I will think forgotten
[2019-12-01 20:38:34 CET] <heinz> Will do it tomorrow.
[2019-12-01 20:38:50 CET] <heinz> You were aksing for the dig scoppe.
[2019-12-01 20:38:54 CET] <heinz> scope
[2019-12-01 20:39:18 CET] <heinz> there is no need to use it for our repair. 
[2019-12-01 20:39:48 CET] <heinz> You spoke about 110 GBP.
[2019-12-01 20:39:56 CET] <heinz> What typeß
[2019-12-01 20:40:01 CET] <heinz> type?
[2019-12-01 20:40:51 CET] <heinz> Hello?
[2019-12-01 20:41:13 CET] <rune> Hello I was looking for the MODs image
[2019-12-01 20:41:48 CET] <rune> Yes, I am thinking about a new scope. The one I have is good, but too big and I need to use it in the shed.
[2019-12-01 20:41:59 CET] <heinz> I will taake the ACE_pcb_topbottom.jpg
[2019-12-01 20:42:13 CET] <rune> So I was thinking of a USB one where the PC screen diplays the traces
[2019-12-01 20:42:18 CET] <heinz> topbot.png
[2019-12-01 20:42:25 CET] <rune> Thanks a lot
[2019-12-01 20:42:43 CET] <rune> I'll send you two links to two scopes I was thinking about.
[2019-12-01 20:43:12 CET] <rune> I found a DSO212 scope. Not sure if its the later version of yours. Send that link already
[2019-12-01 20:43:30 CET] <heinz> I will have a look to them tomorrow. Your board will run!! I am sure. 
[2019-12-01 20:43:48 CET] <heinz> How much isd the DSO212? 
[2019-12-01 20:44:21 CET] <rune> 95.00 roughly
[2019-12-01 20:44:31 CET] <rune> I saw it at 118.00
[2019-12-01 20:44:44 CET] <rune> About 54.00 from China
[2019-12-01 20:44:51 CET] <rune> It pays to shop around
[2019-12-01 20:45:10 CET] <heinz> Found it on amazon. 2 channels, but only 1MHz?
[2019-12-01 20:45:35 CET] <rune> Did you get the russian PCB?
[2019-12-01 20:45:48 CET] <rune> So not an upgrade...
[2019-12-01 20:45:57 CET] <heinz> Yes, I got the Russian board. 
[2019-12-01 20:46:26 CET] <rune> Good, The RAM is easily obtained.
[2019-12-01 20:46:42 CET] <rune> I need to get a bundle of sockets
[2019-12-01 20:46:59 CET] <heinz> My scope is DSO203.
[2019-12-01 20:47:21 CET] <heinz> The Russian board has tweo errors:
[2019-12-01 20:47:27 CET] <rune> Is it the same make as that DSO 212?
[2019-12-01 20:47:37 CET] <heinz> a) designed for the 2532 ROM.
[2019-12-01 20:48:08 CET] <heinz> b) The bottom key line is not ok. 3 cuts needed.
[2019-12-01 20:48:25 CET] <rune> A converter needed. Have you started to build it?
[2019-12-01 20:48:31 CET] <heinz> Concerning the DSO212 I will have a closer look.
[2019-12-01 20:48:50 CET] <heinz> Don't think that it is an upgrade. 
[2019-12-01 20:49:02 CET] <rune> If its only 1 MHz, consider it eliminated. The other two links are 20 MHz and 10 MHz
[2019-12-01 20:49:21 CET] <heinz> 20MHz?
[2019-12-01 20:49:30 CET] <rune> So it says on the spec
[2019-12-01 20:49:49 CET] <heinz> I will look into the specification.

[2019-12-01 20:49:57 CET] <heinz> Let us stop for today.
[2019-12-01 20:50:11 CET] <rune> OK, you have given me lots to think about
[2019-12-01 20:50:12 CET] <heinz> We have 1st of Advent
[2019-12-01 20:50:15 CET] <rune> Thanks
