[2016-04-10 20:11:03 CEST] <heinz> hello dave, i am late. sorry.
[2016-04-10 20:11:09 CEST] <rune> Hello Heinz, I had to setup a new IRC client fast, the old one wanted money to continue
[2016-04-10 20:11:21 CEST] <rune> No pronlems
[2016-04-10 20:11:40 CEST] <heinz> what about your nu?
[2016-04-10 20:11:57 CEST] <rune> I have a lot of questions. 
[2016-04-10 20:12:16 CEST] <rune> I think the first thing to do is wait for the correct udrive chip
[2016-04-10 20:12:29 CEST] <heinz> ?
[2016-04-10 20:12:37 CEST] <heinz> vdr chip?
[2016-04-10 20:12:56 CEST] <heinz> do you mean the micro disk?
[2016-04-10 20:12:59 CEST] <rune> no, U its the closest I have to abreviation for micro
[2016-04-10 20:13:42 CEST] <heinz> let us talk step by step.
[2016-04-10 20:14:12 CEST] <rune> OK, micro drive chip is ordered. It wil lbe here Tuesday or Wednesday
[2016-04-10 20:14:26 CEST] <heinz> is the nu working fully without devices?
[2016-04-10 20:14:47 CEST] <rune> Yes as a computer but some strange things happen.
[2016-04-10 20:15:11 CEST] <heinz> what kind of?
[2016-04-10 20:16:03 CEST] <rune> If I put on cable to the reset button with a push button on the end, I get lots of NMI? or it sticks at TP0A.
[2016-04-10 20:16:20 CEST] <rune> When it does boot the display is corrupted at the bottom
[2016-04-10 20:16:29 CEST] <rune> Without everything is fine
[2016-04-10 20:16:54 CEST] <heinz> i never used the reset button.
[2016-04-10 20:17:19 CEST] <heinz> without reset cable all is fine?
[2016-04-10 20:17:51 CEST] <rune> yes, weird. But definitely happens. I used all day today withiut, then tried with and couldnt get past NMI?
[2016-04-10 20:18:05 CEST] <rune> when I attached cable
[2016-04-10 20:18:33 CEST] <heinz> i am not experienced with this cable.
[2016-04-10 20:19:03 CEST] <rune> Next pronlem is tape load doesnt work. I see you had problems with it too.
[2016-04-10 20:19:42 CEST] <heinz> let us start from the very beginning.
[2016-04-10 20:19:47 CEST] <rune> OK
[2016-04-10 20:20:03 CEST] <heinz> remove all devices and power it on.
[2016-04-10 20:20:12 CEST] <heinz> what happens?
[2016-04-10 20:20:33 CEST] <rune> It boots to the menu screen and I can chose #1 - ZX81
[2016-04-10 20:20:50 CEST] <heinz> ok.
[2016-04-10 20:20:58 CEST] <rune> Then its in ZX81 mode and I can enter programs and run them
[2016-04-10 20:21:04 CEST] <rune> all nice and stable
[2016-04-10 20:21:12 CEST] <heinz> fine.
[2016-04-10 20:21:27 CEST] <heinz> do yuo have the nu with you?
[2016-04-10 20:21:42 CEST] <rune> Its up stairs I can go up with laptop
[2016-04-10 20:22:05 CEST] <heinz> ok. let us just talk about it.
[2016-04-10 20:22:29 CEST] <heinz> did you try looad "pound  abcd" ?
[2016-04-10 20:22:57 CEST] <heinz> or save ...
[2016-04-10 20:23:00 CEST] <heinz> ?
[2016-04-10 20:23:31 CEST] <rune> Oops sometyhing bad happened. 1 minutes
[2016-04-10 20:23:37 CEST] <heinz> sorry, i cant use the pound key.
[2016-04-10 20:25:13 CEST] <rune> fixed, The cover pused a chip out of the socket. All good now
[2016-04-10 20:25:23 CEST] <heinz> ok.
[2016-04-10 20:25:48 CEST] <heinz> did you try the command load "pound abcd?
[2016-04-10 20:26:02 CEST] <heinz> abcd" ?
[2016-04-10 20:26:22 CEST] <rune> yes, I get whatever 4 characters I type after the £
[2016-04-10 20:26:25 CEST] <heinz> or save... ?
[2016-04-10 20:26:37 CEST] <heinz> ok.
[2016-04-10 20:26:49 CEST] <heinz> this also works fine.
[2016-04-10 20:27:00 CEST] <heinz> right?
[2016-04-10 20:27:15 CEST] <rune> Save works too
[2016-04-10 20:27:21 CEST] <heinz> yes.
[2016-04-10 20:27:27 CEST] <rune> yes
[2016-04-10 20:27:28 CEST] <heinz> next:
[2016-04-10 20:27:47 CEST] <heinz> remove the 1025.
[2016-04-10 20:27:56 CEST] <rune> its gone
[2016-04-10 20:28:05 CEST] <heinz> then connect the vdr.
[2016-04-10 20:28:13 CEST] <rune> OK
[2016-04-10 20:28:43 CEST] <heinz> plug in an usb stick with a tap program.
[2016-04-10 20:28:55 CEST] <rune> Done
[2016-04-10 20:29:11 CEST] <heinz> e.g. pinkpth.p
[2016-04-10 20:29:25 CEST] <heinz> sorry, not tap but p.
[2016-04-10 20:29:52 CEST] <heinz> do you have a p ?
[2016-04-10 20:30:05 CEST] <rune> I have 3.p files on the USB
[2016-04-10 20:30:15 CEST] <heinz> ok.
[2016-04-10 20:30:23 CEST] <heinz> now load"+"
[2016-04-10 20:30:31 CEST] <heinz> what happens?
[2016-04-10 20:31:12 CEST] <rune> Nothing, the display says V-LD. Nothing else, screen is black with no cursor
[2016-04-10 20:31:26 CEST] <heinz> that is bad.
[2016-04-10 20:31:58 CEST] <rune> How bad though :(
[2016-04-10 20:32:21 CEST] <heinz> let us hope that the vdr is not ddamaged by the wrong microo disk chip.
[2016-04-10 20:32:35 CEST] <rune> Im using a 4GB USB formatted as FAT32. No activity on the USB or VDrive
[2016-04-10 20:32:42 CEST] <heinz> did yuo removee the 1025 before?
[2016-04-10 20:33:11 CEST] <rune> Its been out all day. But I get the same results whether its in or out
[2016-04-10 20:33:43 CEST] <heinz> but it was in sometimes together with the vdr?
[2016-04-10 20:34:09 CEST] <rune> Yes, and remember it was the wron chip
[2016-04-10 20:34:57 CEST] <heinz> i will check what happens with the nu without a vdr. just wait 1 min.
[2016-04-10 20:35:02 CEST] <heinz> ok?
[2016-04-10 20:35:08 CEST] <rune> ok
[2016-04-10 20:37:54 CEST] * heinz quit ([Errno 104] Connection reset by peer)
[2016-04-10 20:38:14 CEST] * heinz joined
[2016-04-10 20:38:24 CEST] <heinz> i am back.
[2016-04-10 20:38:44 CEST] <heinz> i tried the following things:
[2016-04-10 20:39:04 CEST] <heinz> 1. no vdr and command load"+"
[2016-04-10 20:39:33 CEST] <heinz> in the led no change: just zx81. black screen.
[2016-04-10 20:39:47 CEST] <heinz> i could  stop by break.
[2016-04-10 20:40:13 CEST] <heinz> 2. with vdr but without a stick.
[2016-04-10 20:40:41 CEST] <heinz> led: zx81. onthe screenn: "disk?"
[2016-04-10 20:40:54 CEST] <heinz> try thhis.
[2016-04-10 20:41:37 CEST] <heinz> hello?
[2016-04-10 20:41:39 CEST] <rune> Same result as 1 for both test 1 & 2
[2016-04-10 20:42:28 CEST] <heinz> are you  sure that the vdr is wired in the right way?
[2016-04-10 20:43:11 CEST] <rune> I think so. I will tell you using pins 1-8 on Connector on ZX NU
[2016-04-10 20:43:15 CEST] <rune> 1 - red
[2016-04-10 20:43:21 CEST] <rune> 2 - No connection
[2016-04-10 20:43:41 CEST] <rune> 3 - Orange
[2016-04-10 20:43:50 CEST] <rune> 4 - green
[2016-04-10 20:43:56 CEST] <rune> 5 - Brown
[2016-04-10 20:44:32 CEST] <rune> 6 - Black
[2016-04-10 20:44:51 CEST] <rune> 7 - Yellow
[2016-04-10 20:44:53 CEST] <heinz> seems to be ok.
[2016-04-10 20:45:40 CEST] <rune> Yes, I wonder if i have blown the VDrive
[2016-04-10 20:45:49 CEST] <rune> it feels like it is dead
[2016-04-10 20:45:53 CEST] <heinz> if yuo plug in a stick, hhow does the vdr-led reacted?
[2016-04-10 20:46:35 CEST] <rune> Nothing at all
[2016-04-10 20:46:45 CEST] <heinz> hmmm.
[2016-04-10 20:47:10 CEST] <rune> But it did show V-LD earlier. No lights at stick or VDrive
[2016-04-10 20:47:30 CEST] <heinz> could you measure the voltage red to black?
[2016-04-10 20:48:00 CEST] <rune> Not at the moment. My meter is on my desk at work. I did measure before and it was 5V
[2016-04-10 20:48:16 CEST] <heinz> o.k.
[2016-04-10 20:48:45 CEST] <heinz> let us hope that the vr is ok.
[2016-04-10 20:49:00 CEST] <heinz> wait for the 1024.
[2016-04-10 20:49:18 CEST] <rune> Yes, I think there are lots of teething problems and I need to address them all 1 at a time
[2016-04-10 20:49:30 CEST] <heinz> next try with this chip, without vdr.
[2016-04-10 20:49:38 CEST] <rune> Yep, I still like the board despite the trobles
[2016-04-10 20:50:02 CEST] <heinz> we will overcome the bugs.
[2016-04-10 20:50:37 CEST] <rune> Definitely. I discovered Inverse screen and think its far better than the normal one
[2016-04-10 20:50:51 CEST] <heinz> for the moment no more to say about nu.
[2016-04-10 20:51:17 CEST] <heinz> yes, inverse is better readable on my lcd.
[2016-04-10 20:51:42 CEST] <rune> Nope, I need to go down. I am working away from home all next week and Mrs Rune is complaining I dont sit with her enough
[2016-04-10 20:51:50 CEST] <heinz> did you ever measure the total current?
[2016-04-10 20:52:09 CEST] <rune> No, that was one of my other questions. How to do it?
[2016-04-10 20:52:34 CEST] <heinz> do you use a switching regulator?
[2016-04-10 20:52:48 CEST] <rune> Yes
[2016-04-10 20:53:34 CEST] <heinz> the current with a sw reg is lower than wiith a lin regulator. should be 150 ma.
[2016-04-10 20:53:45 CEST] <heinz> do the following:
[2016-04-10 20:53:53 CEST] <heinz> take the psu.
[2016-04-10 20:54:24 CEST] <heinz> take another audio cable (mono)
[2016-04-10 20:54:40 CEST] <heinz> plug this in the nu.
[2016-04-10 20:55:11 CEST] <heinz> take your meter, switch the current rangge.
[2016-04-10 20:56:01 CEST] <heinz> connect the ground of you psu with the grround of the audio cable.
[2016-04-10 20:56:44 CEST] <heinz> connect the tip of the ppsu cablle with one side of your meter
[2016-04-10 20:57:19 CEST] <heinz> and the tip of the audio cable with the other side of your metr..
[2016-04-10 20:57:40 CEST] <heinz> (your meter is now in line).
[2016-04-10 20:57:47 CEST] <heinz> that is all.
[2016-04-10 20:57:56 CEST] <heinz> aavoid shorts.
[2016-04-10 20:57:58 CEST] <rune> OK, understand that. 
[2016-04-10 20:58:09 CEST] <rune> Yes, no shorts is good :)
[2016-04-10 20:58:18 CEST] <heinz> so, let us stop for todayy..
[2016-04-10 20:58:29 CEST] <rune> I have cables with crocodile clips
[2016-04-10 20:58:46 CEST] <heinz> yes, this is good.
[2016-04-10 20:58:50 CEST] <rune> Yep, I'll email on thursday with hopefully good results
[2016-04-10 20:58:57 CEST] <heinz> fine.
[2016-04-10 20:59:03 CEST] <rune> Nice speaking to you.
[2016-04-10 20:59:27 CEST] <heinz> yes, it was for me too.
[2016-04-10 20:59:29 CEST] <heinz> bye.
