[2018-02-25 19:58:05 CET] not anymore, ttemp below -8 clsius uring night. [2018-02-25 19:58:17 CET] during [2018-02-25 19:58:24 CET] Same here, cold front coming in from Russia now [2018-02-25 19:58:30 CET] Very cold next week [2018-02-25 19:58:52 CET] lakes are frozen? [2018-02-25 19:59:05 CET] Ground is frozen. at least I can walk the dog without geting covered in mud [2018-02-25 19:59:44 CET] We have a mission. To find the Skyware Forth ROM image for the Spectrum [2018-02-25 20:00:06 CET] in two weeks we will have the annual meeting at mahlerts. [2018-02-25 20:00:12 CET] Same idea as ZX81. I can find references to it, but not actual image [2018-02-25 20:00:26 CET] Alrady? 1 Year has passed!!! [2018-02-25 20:00:35 CET] Already [2018-02-25 20:01:37 CET] skyware? ( have abersoft, arctic and bendshop forth for spectrum [2018-02-25 20:01:47 CET] i have [2018-02-25 20:02:04 CET] and robotrics [2018-02-25 20:02:15 CET] Yes, Skyware did H4th for ZX 81, they also brought out an interface with Forth 83 on ROM for Speccy [2018-02-25 20:03:01 CET] I have their Forth ROM for BBC, but no manual. Found the TRS80 manual [2018-02-25 20:04:13 CET] i hav he h4th manual fo zx81, and really, it is written by skywave. [2018-02-25 20:04:53 CET] husband is mentioned as "partner" [2018-02-25 20:05:08 CET] OK, then replace Skywave above. The name does change when mentioned on the web [2018-02-25 20:05:59 CET] i could ask dieter from 8bi-wiki for skywave for speccy. [2018-02-25 20:06:35 CET] Ok, please. I think that would be a good 2nd ROM for Zeddy [2018-02-25 20:07:00 CET] Heres a page where the name is used as Skywave and Skyware. Both D Husband [2018-02-25 20:07:02 CET] http://www.dibsco.co.uk/forth/skywave/zx81-forth [2018-02-25 20:07:35 CET] ? for zedd} ? [2018-02-25 20:07:39 CET] zeddy [2018-02-25 20:08:19 CET] speccy= zx spectrum [2018-02-25 20:08:26 CET] zeddy=zx81 [2018-02-25 20:08:31 CET] For Zeddy, also Speccy BBC TRS80 and now Mascom [2018-02-25 20:08:35 CET] Nascom [2018-02-25 20:09:06 CET] i dont understand. for zx81 we have h4th. [2018-02-25 20:09:21 CET] Yes, but there is also a ROM for the Speccy [2018-02-25 20:09:27 CET] Same company [2018-02-25 20:09:39 CET] But I can only find references to it. [2018-02-25 20:10:09 CET] I'd love to find ROM image and use on Speccy [2018-02-25 20:10:27 CET] the point is that almost nobody in our team is working with forth. [2018-02-25 20:10:52 CET] Thats OK, I will ask anyone who may be able to help. [2018-02-25 20:10:53 CET] but there s a guy from nl who knows a lot. [2018-02-25 20:11:06 CET] I'll keep looking. It must be available somewhere [2018-02-25 20:11:08 CET] i will ask him. [2018-02-25 20:11:14 CET] Thanks [2018-02-25 20:11:55 CET] Any new projects? [2018-02-25 20:12:37 CET] not now. i will give talk at mahlerts about vdrive and speech chi at the zx81. [2018-02-25 20:12:44 CET] chip [2018-02-25 20:13:14 CET] My next project was to 3d print a frame for the keyboard. [2018-02-25 20:13:27 CET] But the holes printed as solid and the frame as space [2018-02-25 20:13:42 CET] Design looks perfect in software [2018-02-25 20:14:35 CET] do you use the desin software from the web? [2018-02-25 20:14:59 CET] Yes, I use some on the web, and also downloaded some to use on my PC [2018-02-25 20:15:29 CET] I downloaded some to split designs then found it in the sw that came with the printer [2018-02-25 20:15:36 CET] i will take the both models ou have sent to m to mahlerts. [2018-02-25 20:16:07 CET] Oh dear, they werent too good. I have the printer set up much better now. [2018-02-25 20:16:14 CET] Do you want bigger ones? [2018-02-25 20:16:37 CET] I printed a nice 2 stroke engine and some fossils [2018-02-25 20:16:39 CET] as far as i know nobody in our team has a 3d printer. [2018-02-25 20:17:09 CET] Im going to do a Spectrum themed case for the Raspi [2018-02-25 20:17:36 CET] no bigger, they aregood as key fob. [2018-02-25 20:17:44 CET] OK. [2018-02-25 20:18:05 CET] Did you drill and add a keyring? [2018-02-25 20:18:27 CET] i will do it. [2018-02-25 20:18:36 CET] excellent. good idea [2018-02-25 20:18:43 CET] send me a picture [2018-02-25 20:19:17 CET] Will there be a good attendance at Malherts this year [2018-02-25 20:19:24 CET] es, o oure [2018-02-25 20:19:28 CET] course [2018-02-25 20:19:33 CET] and will there be a live web cam? [2018-02-25 20:20:03 CET] a lot of people are xpected bein there. [2018-02-25 20:20:19 CET] Good, the scene is still strong [2018-02-25 20:20:40 CET] with the web cam there is the main problem of very poor internet connection. [2018-02-25 20:20:59 CET] mahlerts is in th middle of nowhere. [2018-02-25 20:21:05 CET] Well, plenty of pictures then [2018-02-25 20:21:19 CET] I like looking as I cant go [2018-02-25 20:21:40 CET] to use a mobil one has to go to the 3rd floor. [2018-02-25 20:21:43 CET] Did you get anything at the flea market a few weeks ago [2018-02-25 20:22:34 CET] no sinclair parts, but an old valve meter. [2018-02-25 20:22:58 CET] for ten eur. [2018-02-25 20:23:00 CET] The meter test valves, of the meter uses valves [2018-02-25 20:23:26 CET] or [2018-02-25 20:23:42 CET] test meters are very expensive, more han 150 eur. [2018-02-25 20:24:20 CET] So a very good deal. [2018-02-25 20:24:26 CET] my tool is a meter to measure voltage using valves. [2018-02-25 20:25:10 CET] Do you collect vintage electronics, or is the meter better than modern ones [2018-02-25 20:25:12 CET] they were used in the good old time. [2018-02-25 20:25:51 CET] i bough t just for fun, [2018-02-25 20:26:18 CET] Does Bridget allow you? I have to keep my toys in the shed [2018-02-25 20:26:24 CET] they digital meters e use nowadays are much better. [2018-02-25 20:27:02 CET] upto 10 eur it is allowed. [2018-02-25 20:27:29 CET] highre prices reuires permission by my .wif. [2018-02-25 20:27:35 CET] I can buy, but Liz doesnt like me keeping stuff on the table [2018-02-25 20:27:54 CET] She things the treasure is just Junk [2018-02-25 20:27:59 CET] thinks [2018-02-25 20:28:39 CET] do you use your oscillograph sommes? [2018-02-25 20:28:47 CET] sometimes [2018-02-25 20:29:16 CET] Yes, when I get the bench in my shed cleared. Its still too cold to be out there for more than 30 minutes [2018-02-25 20:30:03 CET] My test Zeddy is sick. Got back porch at ULA but not at CCB [2018-02-25 20:30:31 CET] Its almost constantly connected to oscilloscope [2018-02-25 20:31:06 CET] might be you could tune the ccb? [2018-02-25 20:31:32 CET] what issue? [2018-02-25 20:31:43 CET] The CCB was perfect. But the signal is missing at take off on PCB so before CCB [2018-02-25 20:32:03 CET] I chnaged the ROM, now no signal [2018-02-25 20:32:12 CET] even with original ROM back in [2018-02-25 20:32:33 CET] what zx81 issue? [2018-02-25 20:32:35 CET] I need to trace from ULA to around the CCB takeoff [2018-02-25 20:32:56 CET] I also changed Tranbsistors and Electrolytic caps [2018-02-25 20:33:13 CET] No issue. I was testing 28Bit rom carrier. [2018-02-25 20:33:29 CET] This board is purely a test rig [2018-02-25 20:34:26 CET] no real zx81? [2018-02-25 20:34:43 CET] Yes, its a real ZX81 [2018-02-25 20:35:07 CET] I built a ROM converter from 24 to 28 pin [2018-02-25 20:35:13 CET] so it is either iss1 or iss3. [2018-02-25 20:35:21 CET] Issu [2018-02-25 20:35:31 CET] I cant remember, maybe issue 3 [2018-02-25 20:35:45 CET] Green solder resist [2018-02-25 20:36:08 CET] issue3 has a better ula with better black porch. [2018-02-25 20:36:59 CET] It was working fine, but I heard the chip sockets were very poor and could stop working if anything other than an IC was plucgged in [2018-02-25 20:37:28 CET] i see. [2018-02-25 20:37:57 CET] So maybe desolder the socket and replace with a modern rolled pin on [2018-02-25 20:39:05 CET] do you hav a viddeo signal at ula pin 16? [2018-02-25 20:39:25 CET] Yes [2018-02-25 20:39:52 CET] ut nothing where the wire comes out of the PCB at the case with CCB [2018-02-25 20:40:03 CET] Possible short? [2018-02-25 20:40:04 CET] sometims it is a bit tricky o tune the ccb. [2018-02-25 20:40:54 CET] do you have a ccb from pokemon? [2018-02-25 20:41:06 CET] Yes, I have a few of them [2018-02-25 20:42:13 CET] Most program OK. That one wa sperfect. [2018-02-25 20:42:31 CET] check the ground line of the ccb. [2018-02-25 20:43:23 CET] OK, will do that as soon as I can. Work is a bit busy just now [2018-02-25 20:43:45 CET] o.k. next sunday? [2018-02-25 20:43:49 CET] Can we finish for tonight [2018-02-25 20:43:54 CET] Yes, sure thing [2018-02-25 20:44:03 CET] Bye for now [2018-02-25 20:44:04 CET] all the best.
