[2016-04-24 20:01:03 CEST] Im great thanks, ZX NU is runnign perfectly now [2016-04-24 20:01:11 CEST] and You? [2016-04-24 20:01:30 CEST] yes, you have had a great week. [2016-04-24 20:01:49 CEST] dryer, scope, nu. [2016-04-24 20:02:31 CEST] Wardrobe door, cut the grass, 2 dead ZX81s showing what I think is a video signal with back porch [2016-04-24 20:04:10 CEST] The back porches are different vertical values though. One is about 1.75V in total the ther about 4v [2016-04-24 20:04:50 CEST] how are you satisfied with the scope? [2016-04-24 20:05:54 CEST] Yes, I keep losing my way and am finding "new" features, like pulling a know out to get x10 magnification. Some features I dont totally enderstand. [2016-04-24 20:06:17 CEST] at which point did you check the vid signal? [2016-04-24 20:06:56 CEST] I checked at pin 16 on the ULA [2016-04-24 20:07:22 CEST] then 4/ could be ok. [2016-04-24 20:07:27 CEST] 4v [2016-04-24 20:08:03 CEST] it will take some time to get familiar with a scope. [2016-04-24 20:08:07 CEST] So one is probably OK. The other is about 1.75, Signal drops 1.75, comes up .75 the up 1v [2016-04-24 20:08:31 CEST] it looks ok. [2016-04-24 20:08:37 CEST] But no noise and looks good. [2016-04-24 20:08:57 CEST] could you send a picture? by pn in the forum? [2016-04-24 20:09:03 CEST] The 3rd ZX81 has 5 V on most pins on ROM and Z80 - would this be dead? [2016-04-24 20:09:23 CEST] Sure, I'll try to do this later. [2016-04-24 20:09:25 CEST] check clk signal. [2016-04-24 20:09:32 CEST] How to check? [2016-04-24 20:09:52 CEST] do you have a scheme? [2016-04-24 20:10:26 CEST] yes, on screen [2016-04-24 20:10:45 CEST] at pin 6 of cpu should be a good clk signal. [2016-04-24 20:11:22 CEST] Yep see it going to TR2 [2016-04-24 20:11:30 CEST] tr2 in between ula and cpu is amplifying [2016-04-24 20:11:38 CEST] what should I look for, V and fequency? [2016-04-24 20:12:14 CEST] So clock is going into collector? [2016-04-24 20:12:15 CEST] good sqare shaped singal of amplitude 4v [2016-04-24 20:12:28 CEST] square [2016-04-24 20:12:46 CEST] OK. I'll check that too and take photo [2016-04-24 20:12:52 CEST] frequency about 3.6 M^z [2016-04-24 20:13:11 CEST] MHz [2016-04-24 20:14:01 CEST] you have a dog? [2016-04-24 20:14:08 CEST] big one? [2016-04-24 20:14:20 CEST] Biggish, a boxer [2016-04-24 20:14:56 CEST] snappish? [2016-04-24 20:15:35 CEST] No very docile. Our family have had boxers since before I was born. All very good, especially with the kids [2016-04-24 20:15:49 CEST] ok. [2016-04-24 20:16:12 CEST] my parents had a dog. [2016-04-24 20:16:19 CEST] What kind [2016-04-24 20:16:29 CEST] dachshund. [2016-04-24 20:16:51 CEST] brown with long hairs. [2016-04-24 20:16:59 CEST] A, small and long? Saw a pup it was tiny [2016-04-24 20:17:28 CEST] yes, small with short legs. [2016-04-24 20:17:41 CEST] I though dachshund were all black and tan lige dobberman or rotweiller colours [2016-04-24 20:17:52 CEST] Never heard of a hariy one [2016-04-24 20:17:58 CEST] like [2016-04-24 20:18:39 CEST] might be ( did not use the right translation. [2016-04-24 20:18:50 CEST] wiener dog? [2016-04-24 20:19:07 CEST] Sausage dog, yes :) [2016-04-24 20:19:20 CEST] yes. !hat it is. [2016-04-24 20:19:49 CEST] What were they originally bred for? [2016-04-24 20:20:40 CEST] i think foor hunting. [2016-04-24 20:20:42 CEST] Looked at web, hunting badger and other burrowing animals [2016-04-24 20:21:18 CEST] my friend hhas had a with boxer. [2016-04-24 20:21:18 CEST] My dog gets beaten up by the kitten. [2016-04-24 20:21:55 CEST] white [2016-04-24 20:22:02 CEST] They used to kill white boxer pups because they werent the correct colours [2016-04-24 20:22:05 CEST] white boxer [2016-04-24 20:22:27 CEST] I would take a white boxer [2016-04-24 20:22:27 CEST] right. [2016-04-24 20:22:51 CEST] it was also a bit smaller than usual [2016-04-24 20:23:01 CEST] Oh, do you have any assembler division routine for two 16 bit numbers? [2016-04-24 20:23:32 CEST] Yes, theres a boxer up the street that is about 20cm tallewr than ours. [2016-04-24 20:23:34 CEST] what do you want to do with? [2016-04-24 20:23:46 CEST] 16 bit [2016-04-24 20:23:55 CEST] Im writting a routine to print variables in a basic program. [2016-04-24 20:24:23 CEST] why not completely in basic? [2016-04-24 20:24:31 CEST] Displaying the floating point numbers is fine, but Dimmensioned arrays are two bytes. I need to conver to a string [2016-04-24 20:25:07 CEST] Because basic would reqire variables. I wanted to keep it seperate [2016-04-24 20:25:28 CEST] you want to do this on a zx81? [2016-04-24 20:25:43 CEST] I also want to save the screen, display the variables, then restore the screen [2016-04-24 20:25:55 CEST] for zx81? [2016-04-24 20:26:06 CEST] Yes [2016-04-24 20:26:19 CEST] save to vdr? [2016-04-24 20:26:48 CEST] Thats a possibility. never thought of it [2016-04-24 20:27:30 CEST] i do not know the routines for the zx81. [2016-04-24 20:27:48 CEST] i even have no assembler for it. [2016-04-24 20:27:53 CEST] I have two division routines, but they dont seem to work. [2016-04-24 20:28:13 CEST] But its a hobby and I'll spend time to get them working [2016-04-24 20:28:24 CEST] i have used assembler only oon the spectrum. [2016-04-24 20:28:50 CEST] On ZX NU, Is there a way to move files from vDrive to Microdrive. Some autostart and disable the break key [2016-04-24 20:28:57 CEST] for the spectrrum you have to use the calculatoor. [2016-04-24 20:29:20 CEST] I use TASM which produces a .p file to run on the emulator [2016-04-24 20:29:39 CEST] rst $28 [2016-04-24 20:30:32 CEST] i do not know the zx81 rom good enough. [2016-04-24 20:30:40 CEST] OK, RST28 is available on ZX81 too. I have toni bakers book for both computers [2016-04-24 20:31:14 CEST] I'll look at it over the week. Just started yesterday [2016-04-24 20:31:36 CEST] with rst $28 yyou can compute everrything. [2016-04-24 20:32:36 CEST] a year ago me and roko have written a mc program which uses a lot of computations. [2016-04-24 20:32:38 CEST] Can you use integers, or do you need to convert to floating point? [2016-04-24 20:33:02 CEST] i dont remember. [2016-04-24 20:33:11 CEST] just wait a minute. [2016-04-24 20:35:02 CEST] The ROM can handle integers, but I need the remainder too. But its a step forward [2016-04-24 20:35:42 CEST] i had a look to the prg but did not find the point. [2016-04-24 20:35:57 CEST] no problem, dont worry for now. [2016-04-24 20:36:10 CEST] if you like i can send it to you. [2016-04-24 20:36:26 CEST] the code is commentd. [2016-04-24 20:36:40 CEST] Yes please. I would like take. Its good to learn that way [2016-04-24 20:36:56 CEST] the idea was to soolve a differential equation fast. [2016-04-24 20:37:13 CEST] and to draw the curve. [2016-04-24 20:37:49 CEST] the equation of a damped pendulum. [2016-04-24 20:37:53 CEST] Did you succeed? [2016-04-24 20:38:09 CEST] yes, it looks nice on the screen. [2016-04-24 20:38:34 CEST] one can change the parameters during run. [2016-04-24 20:38:52 CEST] I may be able to use for an idea I have. I want to simulate a bouncy ball being dropped. [2016-04-24 20:39:04 CEST] are you familiar with ode? [2016-04-24 20:39:16 CEST] ode? [2016-04-24 20:39:40 CEST] ordinary diff equations [2016-04-24 20:40:16 CEST] Yes, I did a maths degree almost 40 years ago. Lots of math and lots of time to forget it all. [2016-04-24 20:40:33 CEST] your bouncy ball will follow the same equation [2016-04-24 20:41:31 CEST] Yes, and if I put it over distance I have a simulation for shooting a penguin out of a cannon. [2016-04-24 20:42:09 CEST] as a code pgm? [2016-04-24 20:42:46 CEST] Yes. there were some games that used it when android phones became popular [2016-04-24 20:43:29 CEST] You had to see how far you could get the penguin. Past or over obstacles on the way [2016-04-24 20:43:40 CEST] my pgm is written for the spectrum. [2016-04-24 20:44:00 CEST] Thats OK, I have one or five of those too. [2016-04-24 20:44:22 CEST] I can load is as a TAP on the IF1Bis [2016-04-24 20:44:25 CEST] i have used gens as asembler. [2016-04-24 20:44:41 CEST] do you know gens? [2016-04-24 20:44:44 CEST] Hisoft? [2016-04-24 20:44:58 CEST] yes, and mons too. [2016-04-24 20:45:10 CEST] Yep, got the manuals printed and bound [2016-04-24 20:45:39 CEST] I liked Hisofts software back in the 80s. I had urchased version of Pascal [2016-04-24 20:45:48 CEST] purchased [2016-04-24 20:46:09 CEST] i will send you the coode file and a print of the source. [2016-04-24 20:46:26 CEST] Thanks. Are there any utilities for the ZX NU? [2016-04-24 20:46:41 CEST] i like hisoft pascal very much. [2016-04-24 20:46:46 CEST] Like copy/move between the vDrive and Microdrive [2016-04-24 20:47:31 CEST] the trivial versionn: load from vdr and save to disk. [2016-04-24 20:47:52 CEST] But if the program austostarts and disables the break key? [2016-04-24 20:48:10 CEST] did you get the pgm toolkits.p by siggi? [2016-04-24 20:48:59 CEST] No, I dont think so. I did get a toolkit program but it doesnt do anything specific with the ZXNU [2016-04-24 20:49:18 CEST] It did have a Vars dump. But didnt do dim'd arrays [2016-04-24 20:50:29 CEST] another tooi will send he toolkits.p too. [2016-04-24 20:51:15 CEST] do you know how to save/load code pgms from vdrive? [2016-04-24 20:52:01 CEST] Thanks, I need to collate all the commands and apps for NU. Yes, I have been using it a lot now everything is stable [2016-04-24 20:52:26 CEST] The 4 stroke engine demo has been runnig since 8:00 am [2016-04-24 20:53:01 CEST] rokos pgm for spectrum? [2016-04-24 20:53:25 CEST] No, this is ZX81. Got that and a 2 stroke one [2016-04-24 20:53:41 CEST] please send it to me. [2016-04-24 20:54:05 CEST] No problem. I'll send with the back porch pictures [2016-04-24 20:54:17 CEST] back to code ppgms: do you know how to load hem from vdr? [2016-04-24 20:54:25 CEST] them [2016-04-24 20:54:40 CEST] Yes, load "+programP [2016-04-24 20:54:46 CEST] or loadP [2016-04-24 20:54:53 CEST] will not work. [2016-04-24 20:55:03 CEST] only with basiic. [2016-04-24 20:55:10 CEST] or load "*program" for microdrive [2016-04-24 20:55:21 CEST] no [2016-04-24 20:55:24 CEST] OH, no I dont know how to load in assemblet [2016-04-24 20:55:58 CEST] i mean i command like load "name" code 40000 for spectrum. [2016-04-24 20:56:13 CEST] how too do this with nu? [2016-04-24 20:56:28 CEST] how to do [2016-04-24 20:56:47 CEST] I did see something somewhere. Is the address appended to the program name? [2016-04-24 20:56:59 CEST] yes. [2016-04-24 20:57:09 CEST] the saame with save. [2016-04-24 20:57:16 CEST] Tell mne and I'll put into my document [2016-04-24 20:57:39 CEST] this could be used in a running pgm to save the screen. [2016-04-24 20:58:04 CEST] you nneeed a program for this. [2016-04-24 20:58:50 CEST] it is not implemented in the nu-rom. [2016-04-24 20:59:11 CEST] i will send it to you too. [2016-04-24 20:59:21 CEST] OK, you spoke about someone writing it. Now I remember. [2016-04-24 20:59:30 CEST] iit was created by tom lienhardt. [2016-04-24 20:59:47 CEST] Thats the guy with the website? [2016-04-24 20:59:50 CEST] hence i have called it tom. [2016-04-24 21:00:13 CEST] and he has an electronics business? [2016-04-24 21:00:33 CEST] i do not know. [2016-04-24 21:00:44 CEST] he his fom switzerland. [2016-04-24 21:01:09 CEST] and short wave amateur. [2016-04-24 21:01:16 CEST] I entered tlienhardt.com instead of zx81.tlienhardt.com [2016-04-24 21:01:41 CEST] this is his enterprise? [2016-04-24 21:02:41 CEST] I thinks so. Does T. Lienhard Electronics [2016-04-24 21:02:41 CEST] Münzelweg 10 [2016-04-24 21:02:41 CEST] CH-5506 Mägenwil look like its in Switzerland? [2016-04-24 21:03:12 CEST] yess, it is. CH is switzerlannd. [2016-04-24 21:03:34 CEST] means canton helvetia or something. [2016-04-24 21:04:34 CEST] I thought I was buying some ULAs from Switzerland, they came from Greece [2016-04-24 21:04:51 CEST] my son is callling just now. [2016-04-24 21:05:01 CEST] i have to finish. [2016-04-24 21:05:04 CEST] bye. [2016-04-24 21:05:12 CEST] Mixed up Helvetia with Hellas [2016-04-24 21:05:19 CEST] No probs, buy [2016-04-24 21:05:22 CEST] bye [2016-04-24 21:05:24 CEST] o [2016-04-24 21:05:30 CEST] * heinz quit (EOT) [2016-04-24 21:05:34 CEST] * rune left (Leaving) [2016-04-24 21:31:43 CEST] * dave_ joined [2016-04-24 21:32:23 CEST] * dave_ quit (Leaving)
