[2019-05-05 20:06:33 CEST] <HEINZ> i will change to zx81.
[2019-05-05 20:06:36 CEST] <rune> OK
[2019-05-05 20:06:47 CEST] <HEINZ> it takes 1 min.

[2019-05-05 20:11:02 CEST] <rune> I see that, 
[2019-05-05 20:11:11 CEST] <zheinz> tokes more time.
[2019-05-05 20:11:23 CEST] <zheinz> nickname was already occupied.
[2019-05-05 20:11:34 CEST] <rune> Looks like H4th code needs a little more work
[2019-05-05 20:11:38 CEST] <zheinz> had to try 3 times.
[2019-05-05 20:11:56 CEST] <rune> Well, you are in now which is what counts
[2019-05-05 20:12:16 CEST] <zheinz> i like the h4th way.
[2019-05-05 20:12:27 CEST] <zheinz> but not yet quite good.
[2019-05-05 20:12:46 CEST] <rune> Yes, just some debugging and polishing
[2019-05-05 20:12:55 CEST] <zheinz> i have also a 3rd way to go online.
[2019-05-05 20:13:03 CEST] <rune> How is you health now. Everything good again?
[2019-05-05 20:13:16 CEST] <zheinz> health is ok.
[2019-05-05 20:13:22 CEST] <rune> Good
[2019-05-05 20:13:25 CEST] <zheinz> thank you for asking.
[2019-05-05 20:13:35 CEST] <rune> No problem, I worry ;)
[2019-05-05 20:14:13 CEST] <zheinz> the 3rd way is a pi zero wifi piggyback on a zx81.
[2019-05-05 20:14:32 CEST] <rune>  Now thats impressive.
[2019-05-05 20:14:53 CEST] <zheinz> but still not completely finished.
[2019-05-05 20:15:11 CEST] <rune> To be honest, using an ethernet cable is a problem for me as Liz likes to watch TV on Sundays
[2019-05-05 20:15:32 CEST] <zheinz> pi zero wifi.
[2019-05-05 20:15:51 CEST] <zheinz> no cable anymore.
[2019-05-05 20:16:03 CEST] <rune> What are you doing? Zeddy controls the PI or do you send data to a PI terminal program
[2019-05-05 20:16:29 CEST] <zheinz> i think the last one.
[2019-05-05 20:16:42 CEST] <rune> Cool.
[2019-05-05 20:16:49 CEST] <zheinz> look into the forum.
[2019-05-05 20:17:13 CEST] <zheinz> keyword zx dual uart pi zero.
[2019-05-05 20:17:17 CEST] <rune> I have a Harlequin 99% finished. A ZXNU done except for diodes and logic chips
[2019-05-05 20:17:34 CEST] <rune> and a Multiface 128 finished except for logic chips
[2019-05-05 20:18:25 CEST] <zheinz> you have been very hard-working.
[2019-05-05 20:18:39 CEST] <rune> Yes, and building fences and repairing my car
[2019-05-05 20:18:46 CEST] <rune> I need a holiday
[2019-05-05 20:19:08 CEST] <rune> Oh, Im also using KiCAD to build a Jupiter Ace
[2019-05-05 20:19:31 CEST] <rune> If I can get the PCB design correct I'll get some made up
[2019-05-05 20:20:01 CEST] <zheinz> i would like to have a pcb of jupi ace.
[2019-05-05 20:20:33 CEST] <rune> Well lets see how I get on. Im at a point now I need to print out the schematic and tick off what I have done
[2019-05-05 20:20:36 CEST] <zheinz> there is no ula on a jupi ace, isnt it?
[2019-05-05 20:20:40 CEST] <rune> No
[2019-05-05 20:20:48 CEST] <rune> all just logic chips
[2019-05-05 20:21:10 CEST] <zheinz> easy to find?
[2019-05-05 20:21:17 CEST] <rune> The RAM is 6116 and ROM 2764,
[2019-05-05 20:21:27 CEST] <rune> yes all logic is just 74LSxx
[2019-05-05 20:21:53 CEST] <rune> Im sure that the RAM and ROM could be upgraded to newer stuff
[2019-05-05 20:21:55 CEST] <zheinz> and the keyboard is similiar to zx81?
[2019-05-05 20:22:05 CEST] <rune> Exactly the same layout
[2019-05-05 20:22:14 CEST] <zheinz> i mean the wiring.
[2019-05-05 20:22:25 CEST] <rune> Yes, same wiring
[2019-05-05 20:23:17 CEST] <rune> I would probably prefer to build on a real keyboard instead of using the standard one.
[2019-05-05 20:23:21 CEST] <zheinz> i wish you good luck.
[2019-05-05 20:23:48 CEST] <rune> Well, lets see what happens. I have a great schematic from a spanish or italian
[2019-05-05 20:23:48 CEST] <zheinz> when it will be finished?
[2019-05-05 20:24:15 CEST] <zheinz> what is the size of the board?
[2019-05-05 20:24:17 CEST] <rune> He has built one using wire wrap. But KiCad can that that and use it to design a PCB
[2019-05-05 20:24:34 CEST] <rune> 21cm wide by 18.5 deep.
[2019-05-05 20:25:02 CEST] <rune> But the PCB companies quote on size, which seems to go in steps of 5 cm
[2019-05-05 20:25:05 CEST] <zheinz> that is quite large.
[2019-05-05 20:25:19 CEST] <rune> so I would like to reduce the width to 20 cm
[2019-05-05 20:25:24 CEST] <zheinz> same as the original?
[2019-05-05 20:25:53 CEST] <rune> yes same, motherboard and keyboard are on the same PCB. Half and half.
[2019-05-05 20:26:08 CEST] <zheinz> is there any graphics?
[2019-05-05 20:26:26 CEST] <zheinz> i never have seen a jupi.
[2019-05-05 20:26:29 CEST] <rune> Or it may be possible to reduce by more and ignore the original format
[2019-05-05 20:26:55 CEST] <rune> Yes, sound (beeper), 256x192 (I think) hi res, Black and White display
[2019-05-05 20:27:21 CEST] <zheinz> i am really interested to get a pcb.
[2019-05-05 20:27:29 CEST] <rune> There are also lots of acessories, such as a twister board so you can use zeddy addons
[2019-05-05 20:27:53 CEST] <rune> You will if it comes about. Help with checking schemas and it will be free
[2019-05-05 20:28:27 CEST] <zheinz> gladly.
[2019-05-05 20:28:31 CEST] <rune> Would original dimentions matter to you? Or would a "best fit" with seperate keyboard be acceptable
[2019-05-05 20:28:49 CEST] <zheinz> the last one.
[2019-05-05 20:28:54 CEST] <rune> Same here
[2019-05-05 20:29:11 CEST] <rune> One problem is finding libraries for older components.
[2019-05-05 20:29:38 CEST] <rune> It didnt come with the old RAM but I found a library with that and other stuff in it
[2019-05-05 20:30:07 CEST] <rune> Next is edge connectors. Surprisingly there doesnt seem to be anything for header pins
[2019-05-05 20:31:32 CEST] <rune> Are you still with us?
[2019-05-05 20:31:45 CEST] <zheinz> are you already working on this?
[2019-05-05 20:32:23 CEST] <rune> yes, I have the power side of things done, a lot of logic, ram and rom connections. About 20% done
[2019-05-05 20:32:54 CEST] <rune> But its getting complicated now, so I need the layout in print form so I can tick off connections
[2019-05-05 20:32:56 CEST] <zheinz> good to hear.
[2019-05-05 20:33:35 CEST] <rune> When I try generating the PCB, I get lots of warning about unterminated connections
[2019-05-05 20:33:46 CEST] <rune> So quite a bit to go
[2019-05-05 20:34:34 CEST] <rune> Have you any projects on the table?
[2019-05-05 20:34:40 CEST] <zheinz> i cant help in this direction.
[2019-05-05 20:35:00 CEST] <zheinz> i mean with the devellopment of the pcb.
[2019-05-05 20:35:12 CEST] <rune> It will get there, just get most of the work done and then see what happens
[2019-05-05 20:35:20 CEST] <zheinz> my projects are almost finished.
[2019-05-05 20:35:37 CEST] <rune> Radios? All working
[2019-05-05 20:36:05 CEST] <zheinz> yes:, one week ago i got an old radio.
[2019-05-05 20:36:14 CEST] <zheinz> meanwhile working.
[2019-05-05 20:36:29 CEST] <zheinz> i had to replace 2 tubes.
[2019-05-05 20:36:34 CEST] <rune> Question, can 74LS series be used instead of 74HCT? I know the LS uses more power
[2019-05-05 20:36:43 CEST] <zheinz> and 3 caps.
[2019-05-05 20:36:50 CEST] <rune> Are the tubes new or old stock from the 50s
[2019-05-05 20:37:16 CEST] <zheinz> old stock from my stock.
[2019-05-05 20:37:38 CEST] <zheinz> why you dont use the hct?
[2019-05-05 20:37:42 CEST] <rune> Right, they must have made millions to be available today
[2019-05-05 20:37:56 CEST] <rune> Thats what is says in the ZXNU build document
[2019-05-05 20:38:07 CEST] <rune> But I have many LS
[2019-05-05 20:38:27 CEST] <zheinz> the ls need more power and they are not as stable.
[2019-05-05 20:38:55 CEST] <zheinz> but if you have such a lot then take them.
[2019-05-05 20:39:06 CEST] <rune> Is stability in the range/speed that a ZXNU would run at or is it at the top end
[2019-05-05 20:39:09 CEST] <zheinz> do you use sockets?
[2019-05-05 20:39:19 CEST] <rune> Yes, ZXNU are all turned pin
[2019-05-05 20:39:55 CEST] <zheinz> two other projectss are also finished.
[2019-05-05 20:40:05 CEST] <zheinz> one is the stepper.
[2019-05-05 20:40:55 CEST] <rune> I have the Y plane finished for the laser engraver. I used the DVD chassis in the end
[2019-05-05 20:41:14 CEST] <rune> The Zeddy can send it back and forth
[2019-05-05 20:41:42 CEST] <zheinz> did  you already grave something?
[2019-05-05 20:42:01 CEST] <zheinz> engrave
[2019-05-05 20:42:35 CEST] <rune> No, I need to do the X chassis. I have to much to do in the last month. So thats been put on hold
[2019-05-05 20:43:26 CEST] <zheinz> keep me informed about the progress.
[2019-05-05 20:44:05 CEST] <rune> I will, I may need to change drivers as the ones I have only allow 1/8 step. But I think 1./16 or 1/32 step is needed for accuracy
[2019-05-05 20:44:38 CEST] <zheinz> next weekend i will spend on the baltic sea.
[2019-05-05 20:45:04 CEST] <zheinz> i hope for warmer wheather.
[2019-05-05 20:45:05 CEST] <rune> Really, I will be in Glkasgow, near Baltic Street
[2019-05-05 20:45:13 CEST] <rune> Yes, its got cold recently
[2019-05-05 20:45:28 CEST] <zheinz> we have only 12 degrees now.
[2019-05-05 20:45:30 CEST] <rune> Baltic is Glasgow slang for really cold
[2019-05-05 20:45:44 CEST] <zheinz> interesting.
[2019-05-05 20:45:56 CEST] <zheinz> i will be close to gdansk.
[2019-05-05 20:45:59 CEST] <rune> Where on the Baltic? Are you going to a resort?
[2019-05-05 20:46:13 CEST] <rune> OK, looking at maps now
[2019-05-05 20:46:21 CEST] <zheinz> it is in poland.
[2019-05-05 20:46:31 CEST] <zheinz> big city.
[2019-05-05 20:46:46 CEST] <zheinz> dont know the english name.
[2019-05-05 20:46:59 CEST] <zheinz> danzig.
[2019-05-05 20:47:01 CEST] <rune> Thats where Lech Walessa started the trade union in the shipyards
[2019-05-05 20:47:05 CEST] <zheinz> like in german.
[2019-05-05 20:47:15 CEST] <zheinz> right.
[2019-05-05 20:47:36 CEST] <zheinz> nice old hanse town
[2019-05-05 20:47:37 CEST] <rune> It looks nice. Why did you pick to go there/
[2019-05-05 20:48:03 CEST] <zheinz> i never have been at the polish side of the baltic sea.
[2019-05-05 20:48:24 CEST] <zheinz> and danzig is a travel worth.
[2019-05-05 20:48:30 CEST] <rune> Right. Heh, Im in Glasgow for my sons wedding. His honeymoon is in berlin
[2019-05-05 20:49:00 CEST] <zheinz> have a nice wedding celebration.
[2019-05-05 20:49:23 CEST] <rune> Yes, it may be difficult as my ex wife and her family will be there.
[2019-05-05 20:49:27 CEST] <zheinz> he will go to berlin just after the wedding?
[2019-05-05 20:50:02 CEST] <rune> I think so, Wedding is next friday. So he may go on Saturday or Sunday
[2019-05-05 20:50:32 CEST] <rune> He was there a year oir so ago and really liked the city
[2019-05-05 20:50:50 CEST] <zheinz> berlin is very interesting.
[2019-05-05 20:51:14 CEST] <zheinz> everybody can find something,#as in london.
[2019-05-05 20:51:30 CEST] <rune> Yes, he told me a lot of stories. He doesnt usually get enthusiastic about places
[2019-05-05 20:51:32 CEST] <zheinz> let us stop for today.
[2019-05-05 20:51:57 CEST] <rune> OK, If I have anything on the Jupiter project wotrth looking at I will send it 
[2019-05-05 20:52:15 CEST] <rune> Not next week, we will have a holiday in Scotland after the wedding
[2019-05-05 20:52:40 CEST] <zheinz> talking in two weeks again.
[2019-05-05 20:52:48 CEST] <rune> Yes, bye for now
