(ve watched. [2018-05-20 20:02:37 CEST] weather is beautiful here too. [2018-05-20 20:02:48 CEST] even tomorrow. [2018-05-20 20:02:49 CEST] I was outside all day, still got lots to do in garden [2018-05-20 20:03:04 CEST] Supposed to be 22/23 for rest of the week [2018-05-20 20:03:25 CEST] do you have free tomorrow? [2018-05-20 20:03:45 CEST] no, Im in at work. Planning to retire in October [2018-05-20 20:03:51 CEST] whitsun moday is free in germany. [2018-05-20 20:04:15 CEST] We are off on the 28th? Week tomorrow [2018-05-20 20:05:05 CEST] what is on 28th? [2018-05-20 20:05:24 CEST] last may bank holiday. [2018-05-20 20:05:33 CEST] i see. [2018-05-20 20:05:34 CEST] We always have two in May, start and end [2018-05-20 20:06:03 CEST] 1st of may for demonstrations? [2018-05-20 20:06:04 CEST] French colleagues are off for the week. They have about 15 days more than us [2018-05-20 20:06:31 CEST] Yes, May Day. Was that the bolshvik uprising? [2018-05-20 20:06:46 CEST] you will retire this year? [2018-05-20 20:07:21 CEST] Hopefully, Im fed up working and management are hell bent on destroying the business. Im almost sure its deliberate [2018-05-20 20:08:39 CEST] will liz also stop working? [2018-05-20 20:09:03 CEST] No, she has a bit yet to work. I will be 63 she is only 60 [2018-05-20 20:09:48 CEST] I need to see what I can do with my Parkeon and British Steel pensions [2018-05-20 20:10:14 CEST] Probably lift 25% of parkeon pension at 64.5 yrs [2018-05-20 20:10:35 CEST] same here. [2018-05-20 20:10:48 CEST] I need to see how taking British Steel pension early affects whats paid. [2018-05-20 20:11:08 CEST] if one stops before 66 the pension will be reduced. [2018-05-20 20:11:28 CEST] But if its close to 65, it may not be reduced by much [2018-05-20 20:11:42 CEST] did you work in the steel industry? [2018-05-20 20:11:45 CEST] I pay 300.00 a month in fuel and bridge tolls [2018-05-20 20:12:24 CEST] Also the mileage on my car means more for tyres, repairs etc [2018-05-20 20:12:44 CEST] do you get it back in form of reduced taxis? the fuel etc.? [2018-05-20 20:13:01 CEST] Yes, I started as a chemist and then went into coke ovens as foreman [2018-05-20 20:13:19 CEST] No, we get nothing back in taxes. [2018-05-20 20:13:47 CEST] I was in Steel Works from 17 until 35. [2018-05-20 20:14:33 CEST] the cost for transport or cars will reduced the "income" which has to be rated. [2018-05-20 20:14:56 CEST] Yes, I can survive on much lower savings or salary [2018-05-20 20:15:31 CEST] nearby here there is a steel compny, closed now but open as a museum. [2018-05-20 20:15:38 CEST] My mortgage is paid off. All I need to pay is elcetricity, council tax, phone, etc [2018-05-20 20:15:48 CEST] siemens-martin ovens. [2018-05-20 20:15:56 CEST] very interesting. [2018-05-20 20:15:57 CEST] Same in Scotland. I like working in steel industry [2018-05-20 20:16:06 CEST] Maggie Thatcher closed it all down [2018-05-20 20:16:27 CEST] here it was closed after reunion. [2018-05-20 20:16:59 CEST] do you know siemens-martin ovens? [2018-05-20 20:17:20 CEST] Where I satrted, we had open hearth ovens, then new works had continuous casting. First took 8-12 hours to make 100 tons, second made 100 tones every 1 hour [2018-05-20 20:17:24 CEST] to make steel from iron. [2018-05-20 20:17:33 CEST] I have hear of Seimens. [2018-05-20 20:17:39 CEST] Not Martin [2018-05-20 20:18:13 CEST] siemens [2018-05-20 20:18:49 CEST] Looked it up on web, Siemens martin was open heath ovens. Same as at Dalzell where I started. [2018-05-20 20:19:19 CEST] how did you call your ovens? [2018-05-20 20:19:54 CEST] I cant remember, maybe just open hearth. I am sure there was some sort of name plate on them [2018-05-20 20:20:16 CEST] But I've been sleeping a couple of times since then [2018-05-20 20:20:37 CEST] it was surely a hard job. [2018-05-20 20:21:08 CEST] how did you come to informatics? [2018-05-20 20:21:15 CEST] Yes, I remember at Christmas. The furnace men always smuggled bottles of whisky in. [2018-05-20 20:21:40 CEST] While in steel works I studied part time for a degree. [2018-05-20 20:21:57 CEST] This was mainly mathematics and computing [2018-05-20 20:21:59 CEST] cybernetics? [2018-05-20 20:23:14 CEST] When steel works shut I got job in Royal Ordnance for a couple of years then into full time study at university for degree in software engineering [2018-05-20 20:23:43 CEST] Then I was self employed writing ballistic and explosive modelling programs for Royal Ordnace. [2018-05-20 20:24:09 CEST] was it interesting? [2018-05-20 20:24:32 CEST] Then I was on development team for a Stationers back offic eprogram, the document management, then now as systems engineer fo a parking equipment manufacturer [2018-05-20 20:25:05 CEST] Royal Ordnance was great. I went all over the country testing tank ammunition. [2018-05-20 20:25:09 CEST] lots of different jobs. [2018-05-20 20:25:29 CEST] Usually out in the wild moors which was very enjoyable [2018-05-20 20:25:44 CEST] Yes, some very good, others terrible [2018-05-20 20:26:15 CEST] why did you leave the royal ordnance? [2018-05-20 20:26:48 CEST] Government cuts, they closed the factory. I didnt want to move. My friend did and now travels all over the owrld [2018-05-20 20:27:13 CEST] Also I want to go full time to university, even as a mature student [2018-05-20 20:27:34 CEST] i see. [2018-05-20 20:27:51 CEST] are you english or scottish? [2018-05-20 20:27:56 CEST] Scottish [2018-05-20 20:28:30 CEST] If Scotland stays in EU, I can get a Scottish passport [2018-05-20 20:29:05 CEST] What is the ZX NU news [2018-05-20 20:29:27 CEST] but living close to bristol channel is also nice. isnt it? [2018-05-20 20:29:43 CEST] Yes, absolutely. I love the Forest of Dean [2018-05-20 20:30:10 CEST] ok. nu: works well. [2018-05-20 20:30:22 CEST] do you know the nu? [2018-05-20 20:30:32 CEST] Yes, I have on with a VDrive [2018-05-20 20:30:50 CEST] do you use h4th on it? [2018-05-20 20:31:00 CEST] I have a strange one. It doesnt like H4th [2018-05-20 20:31:38 CEST] we now have a new h4th version which runs on nu perfectly. [2018-05-20 20:31:44 CEST] When I have that ROM the start up screen is offset and corrupted [2018-05-20 20:32:00 CEST] i know this problem. [2018-05-20 20:32:07 CEST] Well, I'd like to try it. Can you send an image please? [2018-05-20 20:32:21 CEST] it is caused by the following: [2018-05-20 20:33:18 CEST] conflict between ram and addresses of the system variables. [2018-05-20 20:33:45 CEST] i will send you the images. [2018-05-20 20:34:07 CEST] Thanks, I am using the BBC a lot just now. I can load 16 ROMS [2018-05-20 20:34:15 CEST] it has 32kb, 4x8kb. [2018-05-20 20:34:28 CEST] Disappointed with Pascal ROM though. Only 3.5 k for program [2018-05-20 20:35:01 CEST] Have you tried the super basic ZX81 rom? [2018-05-20 20:35:10 CEST] never. [2018-05-20 20:35:30 CEST] I think it could be interesting if it runs on real hardware [2018-05-20 20:35:44 CEST] What ROMs do you use? [2018-05-20 20:36:43 CEST] zx81 is on the 2nd bank, h4th on the 3rd one. [2018-05-20 20:37:00 CEST] bank 0 is used for the vdrive. [2018-05-20 20:37:19 CEST] I remember now. [2018-05-20 20:37:21 CEST] now we found the following: [2018-05-20 20:37:55 CEST] we cn use the math fcts from the zx81 rom if we run forth. [2018-05-20 20:38:07 CEST] sqrt, sinus, ... [2018-05-20 20:38:16 CEST] so floating point math [2018-05-20 20:38:24 CEST] by bank switching. [2018-05-20 20:38:44 CEST] yes. floting point too. [2018-05-20 20:38:54 CEST] bokje found it out. [2018-05-20 20:39:14 CEST] Would it be feasible to use the 4th bank for special routines and bank switch? [2018-05-20 20:39:21 CEST] hence, forth get more powerful. [2018-05-20 20:39:41 CEST] Im am always amazed at what can be achieved on old computers [2018-05-20 20:40:01 CEST] the 4th bank is already used to control the system. [2018-05-20 20:40:07 CEST] Now, programmers just through menory and processors at problems [2018-05-20 20:40:13 CEST] memory [2018-05-20 20:40:30 CEST] the new rom was called nu5-oli17. [2018-05-20 20:40:56 CEST] you cal load code files under z381. [2018-05-20 20:41:03 CEST] I will test as soon as I can get it. I prefer ZX81 to BBC [2018-05-20 20:41:05 CEST] zx81 [2018-05-20 20:41:46 CEST] I designed new keys which are half cherry and half bespoke to take the clear key tops. [2018-05-20 20:41:50 CEST] do you have the led display in your nu? [2018-05-20 20:41:54 CEST] Yes [2018-05-20 20:42:01 CEST] It is fully loaded [2018-05-20 20:42:05 CEST] whch color? [2018-05-20 20:42:13 CEST] green I think [2018-05-20 20:42:36 CEST] what has colour got to do with it? [2018-05-20 20:42:47 CEST] i bought 4 pieces by ebay (yellow) for 30 eur. [2018-05-20 20:43:16 CEST] I cant see mine, its enclosed in DK Troniks keyboard [2018-05-20 20:43:22 CEST] there are three clors: green, yellow and red. [2018-05-20 20:43:48 CEST] i have a small window in my cse. [2018-05-20 20:43:54 CEST] case [2018-05-20 20:44:07 CEST] You use the standard zx81 case? Yes? [2018-05-20 20:44:17 CEST] yes, i do. [2018-05-20 20:44:43 CEST] I found my "good" ULA, but no back poarch [2018-05-20 20:44:52 CEST] but the key membran is hard to ue. [2018-05-20 20:45:03 CEST] I need to start testing the board. I dont seem to have anything at the crystal [2018-05-20 20:45:34 CEST] for blck/white a back poarch is not so important. [2018-05-20 20:46:00 CEST] ZX81 doesnt do colour. [2018-05-20 20:46:33 CEST] And read no pack porch as no signal at all [2018-05-20 20:46:37 CEST] back [2018-05-20 20:46:44 CEST] my zx8 also dont have a black poarch. [2018-05-20 20:47:02 CEST] Do you use a modern monitor/tv [2018-05-20 20:47:05 CEST] depending on the monitor. [2018-05-20 20:47:31 CEST] some of them are are bitchy. [2018-05-20 20:48:09 CEST] Most of them... [2018-05-20 20:48:18 CEST] i will take an oscillogram tomorrow and send i to you. from a woking zx81. [2018-05-20 20:49:12 CEST] Thanks, I plan to get a reference for all standard signals. Basically I can put the scope onto a pin, but dont know if the signal is typical or not [2018-05-20 20:50:02 CEST] if you need ref pics i will send it. [2018-05-20 20:50:20 CEST] talk next sunday again? [2018-05-20 20:50:25 CEST] Thanks, I have finished woring on house. Just grass to cut now [2018-05-20 20:50:32 CEST] Yes, I better go wash dishes [2018-05-20 20:50:40 CEST] before liz gets in :) [2018-05-20 20:50:49 CEST] Next week definitely. [2018-05-20 20:50:52 CEST] Bye [2018-05-20 20:50:53 CEST] i have to cut the hedge. [2018-05-20 20:51:09 CEST] bye. [2018-05-20 20:51:11 CEST] Get a fake one. Im thinking of astro turf [2018-05-20 20:51:14 CEST] bye [2018-05-20 20:51:28 CEST] * rune quit (Leaving) [2018-05-20 20:51:41 CEST] * heinz quit (EOT)
