[2018-06-02 21:18:34 CEST] * heinz joined [2018-06-02 21:18:44 CEST] * heinz quit (EOT) [2018-06-03 19:55:58 CEST] * rune joined [2018-06-03 19:59:37 CEST] * heinz joined [2018-06-03 20:00:22 CEST] hello heinz [2018-06-03 20:02:04 CEST] # [2018-06-03 20:02:04 CEST] # [2018-06-03 20:02:19 CEST] hello dave [2018-06-03 20:02:42 CEST] hi, did you see my last email. Good news [2018-06-03 20:02:55 CEST] no, ( didnt. [2018-06-03 20:03:07 CEST] what news? [2018-06-03 20:03:13 CEST] I found a 5" LCD TV in junk shop. [2018-06-03 20:03:25 CEST] NU works perfectly, so problem is TV [2018-06-03 20:03:42 CEST] that is very good. [2018-06-03 20:03:57 CEST] do you have 50hertz in uk? [2018-06-03 20:04:02 CEST] I dont understand hpow it affects the NU running. I had a problem with FAST command, now it runs [2018-06-03 20:04:06 CEST] yes [2018-06-03 20:04:13 CEST] PAL 50 Hz [2018-06-03 20:05:01 CEST] the tv is black/white? [2018-06-03 20:05:15 CEST] Its colour [2018-06-03 20:05:35 CEST] no problems any more? [2018-06-03 20:05:39 CEST] Also resolution isnt great, some scan lines seem to be missing [2018-06-03 20:05:55 CEST] But everything boots and runs [2018-06-03 20:06:12 CEST] this is main important. [2018-06-03 20:06:25 CEST] i use a black paper. [2018-06-03 20:06:34 CEST] yes, Im moving all my retro kit to the summer house now. [2018-06-03 20:06:52 CEST] weather is good? [2018-06-03 20:06:53 CEST] White paper/balck paper... The display is solid. [2018-06-03 20:07:08 CEST] i prefer black pape. [2018-06-03 20:07:14 CEST] Perfect. I have been out all day wotrking on garden and house [2018-06-03 20:07:35 CEST] here it was terriblle hot. [2018-06-03 20:07:38 CEST] Yes, black is best, but its nice that white runs well to now [2018-06-03 20:08:15 CEST] Go to Mull, I think its 12 degrees just now [2018-06-03 20:08:43 CEST] I am hoping for 20 in 2 weeks. Probably 16 [2018-06-03 20:08:50 CEST] when do you will go to mull? [2018-06-03 20:08:55 CEST] 15th june [2018-06-03 20:08:56 CEST] this month? [2018-06-03 20:09:15 CEST] Im looking forward to it. [2018-06-03 20:09:16 CEST] have a nice time there [2018-06-03 20:09:30 CEST] Also thinking of going to Nerja or nearby in October [2018-06-03 20:09:51 CEST] october is a good time. [2018-06-03 20:09:59 CEST] Liz found a finca nortyh of frigliana [2018-06-03 20:10:13 CEST] malaga is also very nice and closer to the airport. [2018-06-03 20:10:33 CEST] i will look for frigliana. [2018-06-03 20:10:35 CEST] Yes, but Malaga is high rise building from what I saw [2018-06-03 20:10:46 CEST] Frigliana is beatiful [2018-06-03 20:10:57 CEST] We went on the bus to there last time [2018-06-03 20:11:38 CEST] Narrow streets - old town. they have many modern facilities too [2018-06-03 20:12:12 CEST] our hotel in nerja wa 1.5 km far from frigliana. [2018-06-03 20:12:30 CEST] i did not remember the name of this village. [2018-06-03 20:12:34 CEST] I thought it was further from Nerja [2018-06-03 20:12:45 CEST] The bus went up the mountain [2018-06-03 20:12:46 CEST] we have been there, really nice. [2018-06-03 20:13:23 CEST] our hotel was north of the highway at the street to frigliana. [2018-06-03 20:13:24 CEST] Yes, we thought Cyprus as Liz lived there for 2 years. Then we discussed nerja and there was no more argument [2018-06-03 20:13:45 CEST] OK, I know where you were [2018-06-03 20:14:03 CEST] We always stayed in my friends flat in the old town [2018-06-03 20:14:30 CEST] I wandered into a cemetary once. Really strange - all burials were abovew ground [2018-06-03 20:14:40 CEST] we have been in the hotel almazara. [2018-06-03 20:15:26 CEST] do you have been in granada? [2018-06-03 20:15:44 CEST] No, I would like to go. Thats an old Moorish city [2018-06-03 20:15:48 CEST] All red brick [2018-06-03 20:16:28 CEST] with a beautiful old palace from the osmanians [2018-06-03 20:16:51 CEST] but you have to order the tickets in advance. [2018-06-03 20:16:52 CEST] Did you hire a car when you were there? [2018-06-03 20:17:18 CEST] yes, we drived a car from airport to nerja. [2018-06-03 20:17:33 CEST] and have used it the full time. [2018-06-03 20:17:45 CEST] I may do that. Last time Liz was robbed when at the bus station [2018-06-03 20:18:00 CEST] also for a trip through the mountains - sierra madra. [2018-06-03 20:18:33 CEST] Yes, that is what I like. I dont like lieing on the beach all day or night clubs [2018-06-03 20:20:03 CEST] they also have good food in granada. [2018-06-03 20:20:25 CEST] try ox tail. [2018-06-03 20:21:27 CEST] Eh. maybe not. I like OXtail soup, but Liz made Oxtail stew/casserole once. I didnt like that [2018-06-03 20:21:46 CEST] She will try anything though [2018-06-03 20:21:52 CEST] yes, stew. perfect. [2018-06-03 20:22:00 CEST] Yeuch!!! [2018-06-03 20:22:17 CEST] Sorry, I think you may same about Haggis. [2018-06-03 20:22:51 CEST] never tried. [2018-06-03 20:23:11 CEST] I love haggis and black pudding (made from blood) [2018-06-03 20:23:18 CEST] but there is a dish made from cow maw. [2018-06-03 20:23:28 CEST] I suppose it is what you are used to eating [2018-06-03 20:23:32 CEST] i like it. [2018-06-03 20:23:37 CEST] Is that Tripe? [2018-06-03 20:23:42 CEST] right. [2018-06-03 20:23:51 CEST] The lining of cows stomachs? [2018-06-03 20:24:04 CEST] but not itaian style. [2018-06-03 20:24:15 CEST] They used to serve it at the works canteen. My boss loved it. I had chips that day [2018-06-03 20:24:29 CEST] I think they cook it in milk here [2018-06-03 20:24:35 CEST] how it is called in uk? [2018-06-03 20:24:39 CEST] It looks very pale [2018-06-03 20:24:43 CEST] Tripe [2018-06-03 20:25:27 CEST] i have eaten it in franfurt in a turkish restaurant. [2018-06-03 20:25:34 CEST] cooked in milk. [2018-06-03 20:25:47 CEST] we dont do it this way. [2018-06-03 20:25:51 CEST] Ah, there may be a difference. Internet says the Maw is the outer part of the stomach. [2018-06-03 20:26:02 CEST] But Tripe is the inner lining. [2018-06-03 20:26:10 CEST] no, i mean tripe. [2018-06-03 20:26:25 CEST] maw was wrong word. [2018-06-03 20:26:28 CEST] OK, I couldnt eat it [2018-06-03 20:26:34 CEST] :P [2018-06-03 20:26:56 CEST] we eat it cooked with paprika and lot of marjoram. [2018-06-03 20:27:01 CEST] a bit soure. [2018-06-03 20:27:31 CEST] let us talk about the nu. [2018-06-03 20:27:35 CEST] I am prejudging. Here is the recipe for haggis. [2018-06-03 20:27:38 CEST] A traditional haggis recipe describes haggis as "sheep's 'pluck' (heart, liver, and lungs), minced with onion, oatmeal, suet, spices, and salt, mixed with stock, and traditionally encased in the animal's stomach and boiled". [2018-06-03 20:28:03 CEST] OK, whats new with the NU [2018-06-03 20:28:04 CEST] sounds delicious. [2018-06-03 20:28:10 CEST] nu. [2018-06-03 20:28:26 CEST] erik fro nl had a new idea. [2018-06-03 20:28:30 CEST] from [2018-06-03 20:28:47 CEST] OK, tell me.... [2018-06-03 20:28:50 CEST] i dont know if you read it in the forum. [2018-06-03 20:29:05 CEST] very interesting idea. [2018-06-03 20:29:23 CEST] first one starts the nu in h4th mode. [2018-06-03 20:30:09 CEST] then, with help of a short code pgm he could switch to zx81 and finally back to h4th. [2018-06-03 20:30:27 CEST] I saw something about that. [2018-06-03 20:30:33 CEST] Does it work? [2018-06-03 20:31:00 CEST] You posted about saving/reloading variables [2018-06-03 20:31:06 CEST] the advantage: one could use the numerical functions from the x81 under h4th. [2018-06-03 20:31:28 CEST] for instance squre roots, sine,... [2018-06-03 20:31:43 CEST] OK, I divide 100/3. When I return to NU, how is result held? [2018-06-03 20:32:22 CEST] you mean 100/3 in zx81 mode? [2018-06-03 20:32:58 CEST] Yes, the answer is 3.33333333333..... When you go back to NU, do you return an arbitary 33333 [2018-06-03 20:33:08 CEST] no. [2018-06-03 20:33:40 CEST] the result 3.333... is on the computationla stack in the zx81. [2018-06-03 20:34:07 CEST] and in NU? [2018-06-03 20:34:56 CEST] the is a routine in the zx81 rom (fp-to-bc) which transfers the entire part into theregister bc. [2018-06-03 20:35:34 CEST] the register bc will now copied to the register hl. then back to the nu. [2018-06-03 20:35:43 CEST] But the BC register can only hold a 16 bit number [2018-06-03 20:35:44 CEST] the result is still in hl. [2018-06-03 20:36:12 CEST] So the number returned is 33333? [2018-06-03 20:36:20 CEST] under h4th the contents of hl can be put to the stack. [2018-06-03 20:36:32 CEST] so you can use it in forth. [2018-06-03 20:36:51 CEST] the number which returns is 3. [2018-06-03 20:37:07 CEST] no, 33. [2018-06-03 20:37:12 CEST] 100/3. [2018-06-03 20:37:32 CEST] Thats like the state in USA in 1920's? That wanted to make Pi = 3 for simplicity [2018-06-03 20:37:50 CEST] Nuts fell off bolts... [2018-06-03 20:38:14 CEST] we can do it better. take sin(45)=0.4041. [2018-06-03 20:38:43 CEST] OK [2018-06-03 20:39:15 CEST] next, multiply in zx81 by 10000. !0this gives 4041...., and entire part is bc=4041. [2018-06-03 20:39:38 CEST] in h4th you get 4041. [2018-06-03 20:39:51 CEST] for digits precision. [2018-06-03 20:40:07 CEST] I get the x10000, but you would need to do the same with 100/3 = 100*10000/3 [2018-06-03 20:40:09 CEST] pi=31416 [2018-06-03 20:40:19 CEST] so surely the result would be 33333 [2018-06-03 20:40:26 CEST] yes. [2018-06-03 20:40:41 CEST] Otherwise, how do you know where the decimal point is? [2018-06-03 20:40:45 CEST] but it makes no sense to use the division. [2018-06-03 20:41:16 CEST] the problems are those fcts which are not implemented in forth. [2018-06-03 20:42:16 CEST] Forth is estensible. Wouldnt it make sense to writh floating point libraries. Sorry, just being devils advocate there [2018-06-03 20:42:22 CEST] write [2018-06-03 20:43:19 CEST] a good library would be quite long. why not use the zx81 calculator? [2018-06-03 20:43:30 CEST] Would the ZX81 floating point routines be faster or slower than anything equivalent written in Forth? [2018-06-03 20:43:53 CEST] it is an idea which cant be simulated by any emulator. [2018-06-03 20:44:03 CEST] only on nu possible. [2018-06-03 20:44:37 CEST] the speed is quite low since switching takes a lot of time. [2018-06-03 20:45:08 CEST] if you like i could send you the short programs for you nu. [2018-06-03 20:45:09 CEST] Is that because you have to restore variables? [2018-06-03 20:45:25 CEST] Yes, off course I and interested. [2018-06-03 20:45:30 CEST] I am [2018-06-03 20:46:02 CEST] Here is a question. Is there any way to print inverse characters with H4th? [2018-06-03 20:46:32 CEST] I tried printing all characters from 0 to 255 and they were the same black/white [2018-06-03 20:47:01 CEST] surprisingly, there is no need to restore the variables. !heu ae preserved. since zx81 and h4th uses different memory parts. [2018-06-03 20:47:44 CEST] Thats interesting. I thought they shared the same RAM [2018-06-03 20:47:46 CEST] ( will send the stuff and you can play withit. [2018-06-03 20:48:01 CEST] Thanks, I'll give it a try. [2018-06-03 20:48:19 CEST] How is your keyboard? I need to see a picture of it [2018-06-03 20:48:50 CEST] h4th usese 7c00 upward for the system variables, and zx81 uses another addresses. [2018-06-03 20:49:22 CEST] }es, i will send a picture next week. [2018-06-03 20:49:51 CEST] brigitte and me want to spend some days in brno for holidays. [2018-06-03 20:49:52 CEST] But doesnt the address space from either system get used in some way by the other [2018-06-03 20:50:11 CEST] Whyere is BRNO? Google.... [2018-06-03 20:50:27 CEST] moravia/czech republic [2018-06-03 20:50:37 CEST] not far from vienna. [2018-06-03 20:50:42 CEST] czech.??? [2018-06-03 20:50:49 CEST] Vienna is austria [2018-06-03 20:51:21 CEST] Is austria to the south? [2018-06-03 20:51:23 CEST] yes, 100km far. [2018-06-03 20:51:50 CEST] did you find brno? [2018-06-03 20:52:31 CEST] yes, I see relationship between them now [2018-06-03 20:52:52 CEST] we already got tickets for the opera. [2018-06-03 20:52:54 CEST] I know mist european countries, but not alsways how they relate to each other [2018-06-03 20:53:01 CEST] cosi fan tutte. [2018-06-03 20:54:24 CEST] a nice city, good located, old castle, old market place,... [2018-06-03 20:54:26 CEST] Thats Mozart... An opera? [2018-06-03 20:54:34 CEST] mozart. [2018-06-03 20:54:35 CEST] Or concert [2018-06-03 20:54:49 CEST] did you have seen it? [2018-06-03 20:54:59 CEST] opera [2018-06-03 20:55:02 CEST] No, google showed me just now [2018-06-03 20:55:26 CEST] very funny act. [2018-06-03 20:55:30 CEST] Was Mozart the guy whose music was very closely related to mathys? [2018-06-03 20:55:47 CEST] Also did he write a lot of masonic music [2018-06-03 20:56:01 CEST] the painter mathys? [2018-06-03 20:56:42 CEST] Sorry, I remember seeing a program in old computer mag. It was possible to write similar music to Mozart by rolling dice [2018-06-03 20:56:47 CEST] mozart lived at the end of the 18th century, and he was a free mason. [2018-06-03 20:56:47 CEST] Maths [2018-06-03 20:57:24 CEST] OK, the masonic part is correct. My cousin was in freemasons and listened to Mozart [2018-06-03 20:57:30 CEST] yes, the rolling dices were also a funny idea of him. [2018-06-03 20:57:53 CEST] there is a movie "amadeus". [2018-06-03 20:58:12 CEST] I have heard of it, but now seen it [2018-06-03 20:58:24 CEST] very good movie. [2018-06-03 20:58:35 CEST] try to watch it from dvd. [2018-06-03 20:58:54 CEST] I will. Is this the one you are going to see? Cosi fan tutte premiere 18/5/2018 [2018-06-03 20:58:59 CEST] liz will be excited. [2018-06-03 20:59:10 CEST] Why? [2018-06-03 20:59:23 CEST] funny movie. [2018-06-03 20:59:55 CEST] It gets good reviews [2018-06-03 21:00:13 CEST] so, next sunday i wil be on the highway returning back from brno. [2018-06-03 21:00:43 CEST] and on sunday 17th you will be at mull. [2018-06-03 21:00:44 CEST] OK, the week after I will be in Mull. Wellington boots or flipflop sandals.... [2018-06-03 21:01:07 CEST] have a nice time there. [2018-06-03 21:01:20 CEST] talking next time in july. [2018-06-03 21:01:22 CEST] Yes, we will talk when i get back. Around the 24th [2018-06-03 21:01:33 CEST] ok. [2018-06-03 21:01:36 CEST] bye [2018-06-03 21:01:38 CEST] Yep. Bye [2018-06-03 21:01:42 CEST] * heinz quit (EOT) [2018-06-03 21:01:44 CEST] * rune quit (Leaving)
