[2018-10-21 20:01:43 CEST] everything is fine. i hope the same for you. [2018-10-21 20:02:03 CEST] yes, some good weather this weekend. What more csan I ask for [2018-10-21 20:02:16 CEST] How is the maths co-processor [2018-10-21 20:02:17 CEST] osan? [2018-10-21 20:02:25 CEST] can [2018-10-21 20:02:29 CEST] csan? [2018-10-21 20:02:34 CEST] can [2018-10-21 20:02:36 CEST] ok. [2018-10-21 20:02:50 CEST] big fingers syndrome [2018-10-21 20:03:03 CEST] the project co-processr is finished from my side. [2018-10-21 20:03:26 CEST] now i am waiting for a productiion of a board. [2018-10-21 20:03:31 CEST] so, what now? a PCB? [2018-10-21 20:03:41 CEST] OK, can I order one? [2018-10-21 20:03:47 CEST] yes. tokabln will do that. [2018-10-21 20:03:54 CEST] Good. [2018-10-21 20:04:10 CEST] i think it will take several weeks. [2018-10-21 20:04:13 CEST] Im trying to run some working Zeddies with the ZXPand [2018-10-21 20:04:28 CEST] and? [2018-10-21 20:04:32 CEST] Without ZXPand, the zeddy works [2018-10-21 20:04:38 CEST] with it, it doesnt [2018-10-21 20:04:57 CEST] Its a 700mA PSU. Could it be the problem? [2018-10-21 20:05:13 CEST] sorry, cant help in this field. ( dont have an zxpand. [2018-10-21 20:05:18 CEST] There is no video signal [2018-10-21 20:05:42 CEST] no sync pulses? [2018-10-21 20:05:55 CEST] Im wondering if the "low" power would kill the signal as that may be the problem with the board Im trying to fix [2018-10-21 20:06:14 CEST] Not tested. Just had 10 minutes this evening [2018-10-21 20:06:48 CEST] Been lifting the lawn today, 3/4 finished. then I'll put sone down [2018-10-21 20:06:49 CEST] i dont know the current consumption of zxpand. [2018-10-21 20:07:02 CEST] I'll PM Charlie [2018-10-21 20:07:12 CEST] do that. [2018-10-21 20:07:30 CEST] What is your next project [2018-10-21 20:07:32 CEST] the co-processor is really fast. [2018-10-21 20:07:44 CEST] I saw you say its 30x faster [2018-10-21 20:07:54 CEST] the board can do the following: [2018-10-21 20:07:57 CEST] is it totally transparent to applications [2018-10-21 20:08:11 CEST] 1. just computing. [2018-10-21 20:09:18 CEST] 2. i can start the original sinclair, the load some programs,#then switch to the apu-rom and run the program there. [2018-10-21 20:09:53 CEST] 3. i can use the board whithout the apu, just to run an external rom. [2018-10-21 20:10:36 CEST] there is a reaaly interesting new rom for the zx81, called bigbang-rom zx81x2. [2018-10-21 20:10:43 CEST] very fasst. [2018-10-21 20:10:47 CEST] fast. [2018-10-21 20:11:08 CEST] did you hear about it? [2018-10-21 20:11:21 CEST] Questions.... [2018-10-21 20:11:25 CEST] in the zx81-forum? [2018-10-21 20:11:51 CEST] Have you tested the speed difference bewteen programs? [2018-10-21 20:12:23 CEST] Not, benchmarks, but real programs, games etc [2018-10-21 20:12:44 CEST] yes, sqr 2*sqr3*sqr4 is 30 times faster than the sinclair rom. [2018-10-21 20:12:58 CEST] benchmark. [2018-10-21 20:13:05 CEST] not with games. [2018-10-21 20:13:13 CEST] dont play games. [2018-10-21 20:13:35 CEST] What about apps? [2018-10-21 20:13:50 CEST] Primes? [2018-10-21 20:14:11 CEST] but if the games would use the sinclair computational routines for sqr or sine, then it should be faster. [2018-10-21 20:14:39 CEST] Maybe the wireframe, flight sim games? Interesting? [2018-10-21 20:14:49 CEST] but i expect that games use just addition executed by code. [2018-10-21 20:15:24 CEST] Im looking up the biggang rom. [2018-10-21 20:15:26 CEST] i could try a game, which one should i select? [2018-10-21 20:16:30 CEST] big bang rom in sinclair zx80/zx81 forum [2018-10-21 20:16:42 CEST] Does it help with logical comparrisons? [2018-10-21 20:16:49 CEST] like big bang in the universe. [2018-10-21 20:16:55 CEST] Maybe LIFE or Flight Sim [2018-10-21 20:17:02 CEST] Like ZX81x2 [2018-10-21 20:17:10 CEST] Looking at benchmarks [2018-10-21 20:17:13 CEST] no, logical operations are not supported. [2018-10-21 20:17:24 CEST] also addition is not. [2018-10-21 20:17:36 CEST] only higher operations. [2018-10-21 20:17:56 CEST] Looking at benchmarks, what about an astronomy program? [2018-10-21 20:18:17 CEST] which one? [2018-10-21 20:18:55 CEST] can you add an additional card if the zxpand is plugged on? [2018-10-21 20:19:16 CEST] I dont know, I'll need to look. There was one to show constellation positions through time. [2018-10-21 20:19:36 CEST] I'll try to find some to test. The results could be really interesting [2018-10-21 20:19:46 CEST] did you hear about th zx81x2 before? [2018-10-21 20:20:22 CEST] I read a post where it was mentioned this evening. But I never registered it was a new rom [2018-10-21 20:20:48 CEST] completely new, and very fast. [2018-10-21 20:20:52 CEST] Oh, it was the ZX More running an instance of Sponzy so that the USB can be used [2018-10-21 20:21:23 CEST] I see the printing routines are a LOT faster [2018-10-21 20:21:50 CEST] yes, mainly printing. [2018-10-21 20:22:19 CEST] Im downloading it now [2018-10-21 20:22:32 CEST] the apu on the board gets very hot. [2018-10-21 20:23:21 CEST] What about heatsink and/or small fan [2018-10-21 20:23:23 CEST] if the temperature is higher as 46 celsius then the apu doesnt work anymore. [2018-10-21 20:23:50 CEST] What IC type is used [2018-10-21 20:23:54 CEST] i have use a thick heatsink now. [2018-10-21 20:24:13 CEST] What about using a Raspberry PI fan? [2018-10-21 20:24:14 CEST] amd9511 [2018-10-21 20:24:34 CEST] there are versions for 1mhz and for 4mhz. [2018-10-21 20:25:08 CEST] 24 pin DIL? [2018-10-21 20:25:10 CEST] but i did not found any differences. [2018-10-21 20:25:20 CEST] 24 pim [2018-10-21 20:25:43 CEST] Water cooling :) [2018-10-21 20:26:08 CEST] the intel c8231 is very expensive. [2018-10-21 20:26:27 CEST] How Expensive? More than 5.00 [2018-10-21 20:26:54 CEST] the main point with both of them is the fact that they need 85ma at 5v and 90ma at 12v. [2018-10-21 20:27:10 CEST] this makes about 1.5 watt. [2018-10-21 20:27:52 CEST] What were they used in originally? [2018-10-21 20:28:38 CEST] in ebay very often is written that the items were pulled from military devices. [2018-10-21 20:29:08 CEST] they were produced in 1979. [2018-10-21 20:29:24 CEST] Are they interchangable. Oh from prehistoric times then [2018-10-21 20:29:30 CEST] the amd chips from china are cheaper, about 5 eur. [2018-10-21 20:31:06 CEST] concerning the zxpand: did you clean the connector carefully? [2018-10-21 20:31:15 CEST] Just looked at ebay, between 15.00 and 85.00 with 66.00 average [2018-10-21 20:32:00 CEST] No, I'll do that next. I did try on 3 Zeddies though and nothing on monitors [2018-10-21 20:32:25 CEST] no idea. [2018-10-21 20:32:38 CEST] The memotech keyboard works though [2018-10-21 20:32:55 CEST] good news. [2018-10-21 20:33:27 CEST] Yes, it was always my wish to get one back in the 80s. They arent nearly as good as they look [2018-10-21 20:33:57 CEST] The keys stick at times if you dont press vertically. So does the BBC keyboard too [2018-10-21 20:34:24 CEST] Best keyboard the the DK'Tronics one I have my ZX Nu in [2018-10-21 20:35:45 CEST] i have sent you a photo of my equipment i use just now for chatting. [2018-10-21 20:36:15 CEST] not very sharp, sorry. [2018-10-21 20:36:27 CEST] Looking [2018-10-21 20:37:43 CEST] Brilliant, you are dedicated indeed! [2018-10-21 20:38:07 CEST] another one. [2018-10-21 20:38:18 CEST] i use the zx81nu. [2018-10-21 20:40:11 CEST] Love the keyboard. I have two cherry keyboards with mechanical keys that I want to use [2018-10-21 20:40:29 CEST] You can get new caps very cheap from china [2018-10-21 20:40:54 CEST] i dont know who was the producer of that keyboard, i bought it on the fleamarket. [2018-10-21 20:41:39 CEST] tell me something about your holidays. [2018-10-21 20:41:45 CEST] Is it converted from a PC keyboard, or produced for the Zeddy market? My bet is its a PC one [2018-10-21 20:42:03 CEST] Holidays were great. 27 min every day. [2018-10-21 20:42:04 CEST] did you visit some towns? [2018-10-21 20:42:30 CEST] We just chilled at the Balcon, ate ice cream, drank beer and people watched most days [2018-10-21 20:42:59 CEST] We went to Frigliana and had a great day. So I have booked 14 days there next year [2018-10-21 20:43:09 CEST] i remember this small village in the mountains. [2018-10-21 20:43:26 CEST] i mean frigliana. [2018-10-21 20:43:30 CEST] The only disappointments were going to the "recommended" restruants. [2018-10-21 20:43:39 CEST] The best were found by chance [2018-10-21 20:43:53 CEST] this is the rule. [2018-10-21 20:44:22 CEST] Our apartment is two bedrooms, beatiful views to the west and sea. 35.00 euro per day [2018-10-21 20:44:24 CEST] do you have been in cordoba? [2018-10-21 20:44:41 CEST] very good price. [2018-10-21 20:44:47 CEST] No, next time we may rent a car and see these places [2018-10-21 20:45:05 CEST] How far is cordoba [2018-10-21 20:45:24 CEST] 160 km from nerja. [2018-10-21 20:45:43 CEST] nice city. not as big as granada. [2018-10-21 20:45:47 CEST] That must be farther than Granada? [2018-10-21 20:46:11 CEST] Liz wants to do the river walk up thye Rio Chiller [2018-10-21 20:46:18 CEST] yes, much further. of course, granada is first choice. [2018-10-21 20:46:57 CEST] There is also caves at the mountain side of Frigliana [2018-10-21 20:47:05 CEST] did you do the river walk? [2018-10-21 20:47:39 CEST] we have been in this caves. really worth to visit them. [2018-10-21 20:47:48 CEST] anNot this year. Next year. Liz got a massive blister on her foot. After she gave me a row for wearing sensible shoes [2018-10-21 20:48:09 CEST] The Nerja caves? Or those behing Frigliana? [2018-10-21 20:48:18 CEST] nerja caves. [2018-10-21 20:48:34 CEST] dave, we will stop now. [2018-10-21 20:48:36 CEST] Yes, I have been in both time I went. [2018-10-21 20:48:49 CEST] spend the rest of the day with our wives. [2018-10-21 20:48:52 CEST] OK, I'll try to send some apops to tes APU speed [2018-10-21 20:48:55 CEST] next week? [2018-10-21 20:49:08 CEST] Bye [2018-10-21 20:49:27 CEST] * rune quit (Leaving) [2018-10-21 20:49:31 CEST] no, next week our son is here for a visit, with wife and babies - twins. [2018-10-21 20:49:46 CEST] bye [2018-10-21 20:50:16 CEST] * heinz quit (EOT)
