[2020-05-03 19:43:58 CEST] * rune joined [2020-05-03 19:56:15 CEST] * bokje joined [2020-05-03 19:56:27 CEST] hi rune [2020-05-03 19:56:59 CEST] * heinz joined [2020-05-03 19:57:08 CEST] hi heinz [2020-05-03 19:57:10 CEST] Hello all! [2020-05-03 19:58:12 CEST] What about your vdrive? [2020-05-03 19:58:52 CEST] my vdrive is working perfectly! [2020-05-03 19:59:08 CEST] but the rom could be improved, [2020-05-03 19:59:09 CEST] That is very good. [2020-05-03 19:59:23 CEST] Rom? What dire i now notice it when the input/output is confused, [2020-05-03 20:00:12 CEST] perhaps there is a way without powering off; [2020-05-03 20:00:48 CEST] HELLO GUYS [2020-05-03 20:00:50 CEST] I di not find any possibility. It was always necessary to shut down. [2020-05-03 20:01:09 CEST] the present routine is very efficient, holmatic? but perhaps it may be more user friendly [2020-05-03 20:01:58 CEST] Sometimes the read-until-prompt-command helps. [2020-05-03 20:02:21 CEST] i saw the code paul is using for the zx80, perhaps there are some ideas there [2020-05-03 20:02:35 CEST] The vdrive refuses new commandfs if it still wants to send somethjing. [2020-05-03 20:02:54 CEST] yes, sometimes it works [2020-05-03 20:03:49 CEST] did you find a solution for the if and ace"s buffer? [2020-05-03 20:04:08 CEST] No. [2020-05-03 20:04:14 CEST] hello rune, how have you been? [2020-05-03 20:04:25 CEST] We have two different IFs . [2020-05-03 20:04:33 CEST] i see [2020-05-03 20:04:35 CEST] Hi Erik Im good. Was waiting until you two finished conversation [2020-05-03 20:04:40 CEST] One works, it contains 4066. [2020-05-03 20:04:55 CEST] Joysticks? [2020-05-03 20:04:55 CEST] these are switches? [2020-05-03 20:05:13 CEST] The other with the EPROM needs additionally a buffer IC, LS367. [2020-05-03 20:05:27 CEST] Dave, this will be the verwsion #5. [2020-05-03 20:05:48 CEST] With the buffer for both ZX81 and Speccy [2020-05-03 20:05:55 CEST] ? [2020-05-03 20:06:06 CEST] The Speccy don't need a buffer. [2020-05-03 20:06:21 CEST] Are there many changes. I may hobernate :) [2020-05-03 20:06:24 CEST] Only the ACE. [2020-05-03 20:06:52 CEST] It is the same problem as wwith the memotech keyboard. [2020-05-03 20:07:21 CEST] The memotech keyboard isnt great on the ZX81 either [2020-05-03 20:07:40 CEST] Looks fantastic but poor performance [2020-05-03 20:09:13 CEST] Hi Dave, didi you have success with your ACE? [2020-05-03 20:09:42 CEST] what does the 367 for the ace do? [2020-05-03 20:09:46 CEST] Does 82 CALL work? [2020-05-03 20:09:48 CEST] No, I am waiting until I get the correct transistor. Tried ZTX313 and 651 and had a corrupted scr4een and frozen keyboard [2020-05-03 20:10:11 CEST] No, I think the Z80 if freezing after about 1 minute [2020-05-03 20:10:13 CEST] But I have seen phantastic CLK signals. [2020-05-03 20:10:35 CEST] Which trasnsistor did you use for them? [2020-05-03 20:10:40 CEST] Yes, thatBMC2396 is better, but I still have screen corrupotion [2020-05-03 20:10:53 CEST] So I will wait to the 2n2396 arrives [2020-05-03 20:11:04 CEST] This can't be connected with the transistor. [2020-05-03 20:11:09 CEST] The BMC may just be a little underpowered [2020-05-03 20:11:25 CEST] Its similar to my V2. [2020-05-03 20:11:36 CEST] Changes the Z80 then to a 10Mhz [2020-05-03 20:11:46 CEST] I only have 6MHz just now [2020-05-03 20:11:50 CEST] You have to pull down a resistor of 270 Ohm at 5V. [2020-05-03 20:12:12 CEST] Where? [2020-05-03 20:12:12 CEST] This gives a current of 20mA. [2020-05-03 20:12:21 CEST] At Tr2. [2020-05-03 20:12:34 CEST] OK, I think it was 1K [2020-05-03 20:12:39 CEST] Hence a ZTX651 could do the job. [2020-05-03 20:13:02 CEST] Do you know what transistor? I'll try changing it [2020-05-03 20:13:20 CEST] Remember I am less than a novice with electronics [2020-05-03 20:13:26 CEST] I mean R8, the resistor at CPU/6. [2020-05-03 20:14:03 CEST] But the CLK was perfect. Don't touch. [2020-05-03 20:14:18 CEST] i have a 220 there, because i coudnt find a 270, works as well.. [2020-05-03 20:14:20 CEST] Search for the error elsewhere. [2020-05-03 20:14:51 CEST] What happens after 82 CAL? [2020-05-03 20:14:56 CEST] CALL [2020-05-03 20:14:59 CEST] Nothing [2020-05-03 20:15:19 CEST] for double speed the input could be connected to clk instead of cnt0, i might try it even though mine is 6 mhz also.. [2020-05-03 20:15:21 CEST] What happens after ENTER? [2020-05-03 20:15:23 CEST] I'll send some screen shots later. [2020-05-03 20:15:36 CEST] Sometimes, the letters and numbers are OK [2020-05-03 20:15:48 CEST] 80% they are corrupted to some extent [2020-05-03 20:16:16 CEST] Something is printed to the top of the screen and sometimes I see OK or just K [2020-05-03 20:16:22 CEST] Did you try 2 3 + . [2020-05-03 20:16:26 CEST] Yes [2020-05-03 20:16:34 CEST] And? [2020-05-03 20:16:50 CEST] It usually takes the first 2 and then acts like the next word is unknown [2020-05-03 20:17:01 CEST] Like if you enterd ylist [2020-05-03 20:17:13 CEST] Cursor is placed in front of y [2020-05-03 20:17:53 CEST] Does it answer correct for "VLIST"? [2020-05-03 20:18:02 CEST] I dont know [2020-05-03 20:18:22 CEST] The full screen corrupts and then changes continuously until it freezes [2020-05-03 20:18:36 CEST] Swap the ROM. [2020-05-03 20:18:39 CEST] The characters look like boxes, which get thicket and thicker lines [2020-05-03 20:18:57 CEST] I will try that, but the ROM was out of my working ACE [2020-05-03 20:19:26 CEST] I took it out when Erik sent the ROM with the INIT [2020-05-03 20:20:06 CEST] Did you try different CPUs? [2020-05-03 20:20:29 CEST] Yes, 4 different ones, 3 new [2020-05-03 20:20:49 CEST] Does Paul intend to build the V3? [2020-05-03 20:20:57 CEST] Maybe Im buying all the damaged stock [2020-05-03 20:21:19 CEST] I havent said to him yet. I was hoping for the transistor to arrive first [2020-05-03 20:21:54 CEST] I am sure that the3 transistor is not the problem. The CLK is perfect. Couldn't be better. [2020-05-03 20:22:44 CEST] OK, memory? I have 14 chips, they cant all be bad. I sent 3 at random to Erik and they worked [2020-05-03 20:23:16 CEST] Are you sure that you did not forget soldering one pin? [2020-05-03 20:23:29 CEST] But low power transistor = frozen screen and keyboard [2020-05-03 20:23:46 CEST] Almost correct transistor = almost working ACE [2020-05-03 20:24:03 CEST] I dont think I forgot and have reflowed al pins on main ICs [2020-05-03 20:24:10 CEST] ok, try the transoistor. [2020-05-03 20:24:20 CEST] Maybe need to do the same on the 74s [2020-05-03 20:24:46 CEST] Do you still need 2 joystick interfaces? [2020-05-03 20:24:57 CEST] Do you want to wait for V5 [2020-05-03 20:25:27 CEST] Dave, the idea to bulid a joystick IF originates in the problem that most of the games for the ACE have to be played by keyboard. [2020-05-03 20:25:42 CEST] I also need to order more memory/vdrive boards [2020-05-03 20:25:58 CEST] Now it came out that version 3 doesnot fit to the ACE. [2020-05-03 20:26:17 CEST] To be honest, the good ACE games dont need joysticks [2020-05-03 20:26:32 CEST] Why doesnt it fit? [2020-05-03 20:26:34 CEST] Which one? [2020-05-03 20:26:53 CEST] Sudoku, ACE star, chess, tetris [2020-05-03 20:26:58 CEST] I have a long list of games which need a keyboard. [2020-05-03 20:27:15 CEST] Tetris needs a keyboard. [2020-05-03 20:27:21 CEST] All games need a keyboard, but the arcade games [2020-05-03 20:27:26 CEST] Much easier to play with a joystick. [2020-05-03 20:28:04 CEST] I am maybe used to playing with keyboard [2020-05-03 20:28:43 CEST] But what is the problem and can we convert the Zeddy joystick to work with the ACE? Rather than using a twister card [2020-05-03 20:29:15 CEST] * heinz quit (CGI:IRC (EOF)) [2020-05-03 20:29:30 CEST] Was it something I said? :( [2020-05-03 20:29:31 CEST] * heinz joined [2020-05-03 20:29:37 CEST] Hello again [2020-05-03 20:29:51 CEST] The Zeddy card works perfectly with the ACE. [2020-05-03 20:29:55 CEST] The Zeddy card works perfectly with the ACE. [2020-05-03 20:30:03 CEST] But not the version 3. [2020-05-03 20:30:16 CEST] That with an Eprom. [2020-05-03 20:30:28 CEST] I thougfht that was Version 4 [2020-05-03 20:30:39 CEST] ??? [2020-05-03 20:31:01 CEST] We have on efor the Zeddy - V1, and one for the Speccy - V3. [2020-05-03 20:31:31 CEST] I am sure you mentioned V4. [2020-05-03 20:31:38 CEST] V1 works on ACE. Did you try it? [2020-05-03 20:32:01 CEST] No, the ACE I am trying to get to work is permanently set up. [2020-05-03 20:32:12 CEST] Any time I have free is used for that. [2020-05-03 20:32:38 CEST] Although I am building pre-configured PCBs for the V1 [2020-05-03 20:35:28 CEST] Hi Erik, I meant to email you. The SAVE routine didnt work [2020-05-03 20:35:41 CEST] Erik, are you still here in? [2020-05-03 20:36:13 CEST] He is gone to feed the cat [2020-05-03 20:36:20 CEST] yes i tried save only once... need more time i guess [2020-05-03 20:36:20 CEST] I think so. [2020-05-03 20:36:58 CEST] No problem, the joystick factory is very busy for the forseeable future [2020-05-03 20:37:06 CEST] Does your Vdrive freezes quite often? [2020-05-03 20:37:35 CEST] Mine, only when I make an error. [2020-05-03 20:37:47 CEST] No, I mean Erik's. [2020-05-03 20:37:49 CEST] Then it sits waiting for some input [2020-05-03 20:37:52 CEST] He wrote about it. [2020-05-03 20:38:17 CEST] Does the led on the vdrive flash when it freezes [2020-05-03 20:38:55 CEST] Heinz, Erik I need to go now. liz wants to watch a movie [2020-05-03 20:38:58 CEST] yes mine also only freezes when i make a mistake... but i make mistakes ;-) [2020-05-03 20:39:11 CEST] My experience is that a flashing LED indicates more data to be read. [2020-05-03 20:39:16 CEST] ok good luck with your ace! [2020-05-03 20:39:34 CEST] good to know! [2020-05-03 20:39:43 CEST] yes me too. I tried to write a word to read the characters until there were none left. It helps sometimes [2020-05-03 20:39:44 CEST] So let us stop for today. [2020-05-03 20:39:59 CEST] Bye. [2020-05-03 20:40:01 CEST] Yep, bye I will catch up with you during the week. [2020-05-03 20:40:03 CEST] Bye [2020-05-03 20:40:03 CEST] ok bye! [2020-05-03 20:40:06 CEST] Have fun with the movie,.
