[2017-05-14 20:01:10 CEST] No, the scope was giving crazy scans. I thought it was dead [2017-05-14 20:01:24 CEST] I have the calibration signal back [2017-05-14 20:01:38 CEST] and the back porch, but not done much more [2017-05-14 20:01:54 CEST] other than trace connections from Z80 to ULA, ROM, RAM [2017-05-14 20:01:57 CEST] check the clk signal. [2017-05-14 20:02:12 CEST] I on pin 6. [2017-05-14 20:02:20 CEST] yes. [2017-05-14 20:02:42 CEST] I get saw tooth, but I never worked out frequency [2017-05-14 20:02:45 CEST] right amlitude,#right frequency? [2017-05-14 20:03:09 CEST] there should be no tooth but meander. [2017-05-14 20:03:14 CEST] ? Im a novice at this. Would it be half that from the crystal? [2017-05-14 20:03:24 CEST] yes. [2017-05-14 20:03:44 CEST] This signal is up 45 degrees down 45 degrees, repeat ad infinitum [2017-05-14 20:03:46 CEST] time base is measured inn sec per unit. [2017-05-14 20:04:07 CEST] the reziproce is the frequenncy. [2017-05-14 20:04:34 CEST] the shhape at zx 1a was good, [2017-05-14 20:04:46 CEST] I'll try again next week. Im not even sure the ROM in one of the boards is ZX81 [2017-05-14 20:05:13 CEST] OK, then 1b and 3 was not what we wanted. [2017-05-14 20:05:20 CEST] yes. [2017-05-14 20:05:28 CEST] I'll try swapping ROM on 1a [2017-05-14 20:05:35 CEST] mark had saaid the same. [2017-05-14 20:05:56 CEST] good idea. [2017-05-14 20:06:11 CEST] 1a ULA pin 14 and Z80 pin 6 were the same [2017-05-14 20:06:27 CEST] not quite. [2017-05-14 20:07:12 CEST] there is tr2 in between. [2017-05-14 20:07:16 CEST] OK I think I should concentrate on 1a [2017-05-14 20:07:41 CEST] check the frequncy for 1a. [2017-05-14 20:07:55 CEST] then pin14 cpu. [2017-05-14 20:07:57 CEST] I've been collecting parts for my ZX80 board. [2017-05-14 20:08:06 CEST] there was a scann. [2017-05-14 20:08:21 CEST] Got all resistors except 1. Looking for caps next [2017-05-14 20:08:21 CEST] scan for pin14. [2017-05-14 20:08:38 CEST] this picture looks steady. [2017-05-14 20:08:45 CEST] was it so? [2017-05-14 20:09:22 CEST] Yes first time when I took photo. It was just Fuzzy mess when I tried wednesday and thirsday [2017-05-14 20:09:24 CEST] check one of the address lines pin34-40 cpu. [2017-05-14 20:09:49 CEST] they should oscillate. [2017-05-14 20:09:56 CEST] "fuuzzy" [2017-05-14 20:10:15 CEST] Yes out of focus with lots of patterns superimposed. [2017-05-14 20:10:25 CEST] Like reading graphs when drunk [2017-05-14 20:10:34 CEST] but the rom is important. [2017-05-14 20:10:42 CEST] I was sober by the way [2017-05-14 20:11:03 CEST] check for zx81 [2017-05-14 20:11:29 CEST] ZX81? [2017-05-14 20:11:55 CEST] i mean the rom, it should be a zx81-rom. [2017-05-14 20:12:13 CEST] I think I have a different ROM in each board [2017-05-14 20:12:24 CEST] swap them [2017-05-14 20:12:33 CEST] And an eprom in the board that works. [2017-05-14 20:12:40 CEST] OK, good idea [2017-05-14 20:12:51 CEST] They are always 24 pin and compatible [2017-05-14 20:12:54 CEST] you have a working bboard? [2017-05-14 20:13:34 CEST] I have three working ZX81s, but didnt really want to open one. Byut it is probably best thing to do [2017-05-14 20:14:10 CEST] yes, to compare the ignals and to learn something. [2017-05-14 20:14:44 CEST] OK, I will open one later, without the internal ram expansion [2017-05-14 20:15:18 CEST] good wheather for biking? [2017-05-14 20:15:45 CEST] Yes, its great here. Got the insurance renewal in = 280 up from 190 [2017-05-14 20:16:09 CEST] so I renbetered my info on their web site and got a quote of 150 [2017-05-14 20:16:25 CEST] I think I need to speak to them this week [2017-05-14 20:16:53 CEST] dont understand. [2017-05-14 20:17:04 CEST] is it cheaper now? [2017-05-14 20:17:28 CEST] Well last year is was 190, this year they said best they could do was 280 [2017-05-14 20:17:49 CEST] do you mean pounds? [2017-05-14 20:17:50 CEST] so i went onto the web site and entered my details again and they quoted 150 [2017-05-14 20:17:52 CEST] yes [2017-05-14 20:18:04 CEST] i see. [2017-05-14 20:18:08 CEST] someone is lieing to me [2017-05-14 20:18:25 CEST] good luck. [2017-05-14 20:18:48 CEST] Yep, I just love spending my time aguing with insurance people [2017-05-14 20:19:10 CEST] But if you dont they charge more each year and hope you just accept it [2017-05-14 20:19:32 CEST] right. [2017-05-14 20:19:41 CEST] What about you? Getting out on the bike? [2017-05-14 20:19:56 CEST] eBike? [2017-05-14 20:20:09 CEST] but there are clearr financial formulas to compute the charge. [2017-05-14 20:20:45 CEST] this weekeend we had guests. [2017-05-14 20:20:52 CEST] Not really, same with breakdown services. They up the price and only offer a lower one if you phone and complain [2017-05-14 20:21:17 CEST] and weve visited an old steel plant. [2017-05-14 20:21:35 CEST] Non-working? [2017-05-14 20:21:43 CEST] no more. [2017-05-14 20:21:47 CEST] I worked in a steel planet for 20 years [2017-05-14 20:21:52 CEST] plant [2017-05-14 20:21:53 CEST] it was very big. [2017-05-14 20:22:13 CEST] 2 millions tons steel per year. [2017-05-14 20:22:15 CEST] Was it an official tour, or did you just go and wander round [2017-05-14 20:22:29 CEST] it is a museum. [2017-05-14 20:22:44 CEST] Ah, sort of heritage/industrial thing [2017-05-14 20:23:05 CEST] they had 12 siemens-martin ovens. [2017-05-14 20:23:36 CEST] Did it have integrated iron plant and coke plant [2017-05-14 20:23:44 CEST] both. [2017-05-14 20:24:14 CEST] I worked in chemistry lab analysing all sorts from production process then moved to coke ovens [2017-05-14 20:24:17 CEST] they uuseed only scrap. [2017-05-14 20:24:35 CEST] Scrap would be mostly refined [2017-05-14 20:24:46 CEST] so no need to smelt iron ore [2017-05-14 20:24:47 CEST] riht. [2017-05-14 20:25:11 CEST] In the last days of our plant we had a big order for steel for Ladas [2017-05-14 20:25:21 CEST] they used oiil for heating. [2017-05-14 20:25:41 CEST] There was a mistake and we supplied high alloy steel. So last ladas will never rust [2017-05-14 20:26:10 CEST] you should buy oone. [2017-05-14 20:26:14 CEST] one [2017-05-14 20:26:25 CEST] We used gas from coke ovens then electricity [2017-05-14 20:26:38 CEST] I havent seen a lada in years here. [2017-05-14 20:27:02 CEST] I havent seen many cars from the 70s or 80s in years come to think of it [2017-05-14 20:27:26 CEST] There is a web site that give the numbers of the old cars still registered [2017-05-14 20:27:39 CEST] some are less than 100 [2017-05-14 20:28:15 CEST] lads or minis?? [2017-05-14 20:28:20 CEST] ladas [2017-05-14 20:28:37 CEST] ladas, rovers, triumphs, fords, [2017-05-14 20:28:40 CEST] minis [2017-05-14 20:29:00 CEST] most cars are from 2000s [2017-05-14 20:29:14 CEST] vauxhall is now a part of citroen. [2017-05-14 20:29:32 CEST] how do youthink about that? [2017-05-14 20:29:34 CEST] Yes, and I found out the engine in my nissan is puegeot [2017-05-14 20:29:51 CEST] surprising. [2017-05-14 20:30:11 CEST] french words? [2017-05-14 20:30:16 CEST] Yes, but the xtrail and other nissans were designed and built in UK at newcastle [2017-05-14 20:30:28 CEST] NISSAN is japanese [2017-05-14 20:30:36 CEST] i know. [2017-05-14 20:30:48 CEST] but nngine french? [2017-05-14 20:30:52 CEST] engine [2017-05-14 20:30:54 CEST] Yes [2017-05-14 20:31:02 CEST] at least the electrics arent [2017-05-14 20:31:23 CEST] Peugeot make good engines, but electrical system is terrible [2017-05-14 20:32:08 CEST] new castele belons to scotland? [2017-05-14 20:32:14 CEST] I had a 407 at work, it losts all lights at 70mph on a busy road and sometimes all the lights on the dash would come on [2017-05-14 20:32:16 CEST] belonngs [2017-05-14 20:32:38 CEST] No, its right at the north-east of england. [2017-05-14 20:32:39 CEST] some shorts? [2017-05-14 20:32:50 CEST] No shorts, gremlins [2017-05-14 20:33:24 CEST] Once the heating failed as I passed a huge lorry. all windows steamed up [2017-05-14 20:33:26 CEST] gremliin? [2017-05-14 20:33:49 CEST] the little imps that live in engines and cause all sorts of trouble [2017-05-14 20:33:57 CEST] imps - little people [2017-05-14 20:34:08 CEST] i see. [2017-05-14 20:34:31 CEST] things that happen with no explanation [2017-05-14 20:34:34 CEST] ok, lets stop for today. [2017-05-14 20:34:49 CEST] OK, I have stuff to do on raspberry pi [2017-05-14 20:34:58 CEST] I'll talk to you later [2017-05-14 20:35:03 CEST] bye [2017-05-14 20:35:13 CEST] next sunday? [2017-05-14 20:35:20 CEST] yes [2017-05-14 20:35:33 CEST] bye [2017-05-14 20:35:35 CEST] * rune quit (Leaving) [2017-05-14 20:35:40 CEST] * heinz quit (EOT) [2017-05-14 20:43:09 CEST] * siggi quit (ping timeout) [2017-05-14 21:11:07 CEST] * siggi joined [2017-05-14 23:59:55 CEST] * siggi quit (EOT)
