[2020-02-16 19:59:07 CET] <heinz> Hello Dave.
[2020-02-16 20:00:03 CET] <heinz> Did you have strong storm?
[2020-02-16 20:01:04 CET] <rune> Hello Heinz, yes, the rain is moving sideways
[2020-02-16 20:01:11 CET] <rune> Lots of areas flooded
[2020-02-16 20:01:50 CET] <rune> I think I should stay in bed tomorrow
[2020-02-16 20:03:13 CET] <rune> did you get blown away?
[2020-02-16 20:03:14 CET] <heinz> Are you ill?
[2020-02-16 20:03:30 CET] <rune> No, its too horrible to go to work ;)
[2020-02-16 20:03:38 CET] <heinz> I see. 
[2020-02-16 20:03:54 CET] <heinz> What about the forecast?
[2020-02-16 20:03:54 CET] <rune> I did drop a pack of wood on my foot. Got a nice purple toe
[2020-02-16 20:04:06 CET] <heinz> You told me about it.
[2020-02-16 20:04:06 CET] <rune> Still lots of rainb to come
[2020-02-16 20:04:23 CET] <rune> How did the joystick go?
[2020-02-16 20:04:46 CET] <heinz> The joystick does not work.,
[2020-02-16 20:04:58 CET] <heinz> Did you try a joystick?
[2020-02-16 20:05:01 CET] <rune> thats not good
[2020-02-16 20:05:18 CET] <rune> No, Im trying to work out what to do with your vdrive code
[2020-02-16 20:05:27 CET] <rune> I cant get it to do anything
[2020-02-16 20:05:52 CET] <heinz> You can read and write single bytes to the vdrive. 
[2020-02-16 20:06:02 CET] <heinz> And also strings.
[2020-02-16 20:06:17 CET] <heinz> If you need assistance, please ask me.
[2020-02-16 20:06:23 CET] <rune> I am asking
[2020-02-16 20:06:41 CET] <rune> I see when I type TXT DR DIR
[2020-02-16 20:07:01 CET] <rune> DIR is put into the PAD plus the length
[2020-02-16 20:07:08 CET] <rune> But it just returns OK
[2020-02-16 20:07:14 CET] <rune> Sometimes crashes
[2020-02-16 20:07:27 CET] <heinz> Now you could proceed with SEND DR
[2020-02-16 20:07:48 CET] <rune> Ah, I was just trying SEND
[2020-02-16 20:07:55 CET] <heinz> After this the vdrive wants to send the directory.
[2020-02-16 20:08:20 CET] <heinz> Sorry, DR SEND (polish backwards) 
[2020-02-16 20:08:36 CET] <rune> So DR corresponds to the COMMAND" in the SEND word comments
[2020-02-16 20:09:08 CET] <heinz> Next you have to read from Vdrive: RDPT <CR> will read until D:>
[2020-02-16 20:09:52 CET] <heinz> Yes, corresponds.
[2020-02-16 20:09:52 CET] <rune> Do all drive commands end with >?
[2020-02-16 20:10:21 CET] <rune> I am thinking of making a folder, CD, Delete a file etc
[2020-02-16 20:10:26 CET] <heinz> The commands don't end with >, but the response from vdrive.
[2020-02-16 20:10:47 CET] <rune> OK, I will be testing that later :)
[2020-02-16 20:11:01 CET] <heinz> Yes, try it. One needs some practice.
[2020-02-16 20:11:18 CET] <rune> Next question, you saend to McKlaud that you could save a TAP from EightyOne
[2020-02-16 20:11:24 CET] <heinz> My joystick works technically perfect.
[2020-02-16 20:11:25 CET] <rune> I can only get TZX
[2020-02-16 20:11:54 CET] <heinz> EO: chosse .tap
[2020-02-16 20:12:06 CET] <heinz> choose
[2020-02-16 20:12:08 CET] <rune> I cant, there is no option. 
[2020-02-16 20:12:16 CET] <rune> What version do you use?
[2020-02-16 20:12:20 CET] <heinz> Just open the EO
[2020-02-16 20:12:36 CET] <rune> its open
[2020-02-16 20:12:38 CET] <heinz> Did you?
[2020-02-16 20:12:46 CET] <rune> yes
[2020-02-16 20:13:08 CET] <heinz> Then TOOLs, tape manager.
[2020-02-16 20:14:08 CET] <rune> I see it. Thanks. I was sure I had checked and only saw TZX
[2020-02-16 20:14:11 CET] <heinz> Did you?
[2020-02-16 20:14:19 CET] <rune> Yes, got it.
[2020-02-16 20:14:27 CET] <rune> Twice as happy now
[2020-02-16 20:14:35 CET] <heinz> Try : x ;
[2020-02-16 20:14:42 CET] <heinz> as example.
[2020-02-16 20:14:56 CET] <heinz> on EO.
[2020-02-16 20:15:28 CET] <rune> I have Dark Star loaded just now
[2020-02-16 20:15:36 CET] <heinz> ok.
[2020-02-16 20:15:43 CET] <rune> It works.
[2020-02-16 20:15:45 CET] <heinz> Then save DS <CR>
[2020-02-16 20:16:03 CET] <heinz> It appears in the tape manager.
[2020-02-16 20:16:19 CET] <rune> yep
[2020-02-16 20:16:49 CET] <heinz> If you save on disc, you will be ask for a path, name and file type..  
[2020-02-16 20:16:57 CET] <heinz> choose .tap.
[2020-02-16 20:17:03 CET] <heinz> OK?
[2020-02-16 20:17:17 CET] <rune> yes, very happy
[2020-02-16 20:17:41 CET] <heinz> Back to my joystick:
[2020-02-16 20:17:58 CET] <heinz> I can read by: IN 253 . <CR>
[2020-02-16 20:18:00 CET] <rune> OK, that link I sent has a program to test it
[2020-02-16 20:18:10 CET] <heinz> And got the right bytes.
[2020-02-16 20:18:24 CET] <heinz> But the games I've tried did not react.
[2020-02-16 20:18:40 CET] <heinz> I will try.
[2020-02-16 20:18:50 CET] <rune> It says to use port 1
[2020-02-16 20:19:12 CET] <heinz> There is only one example of joysticks at the archive, and they use the IO address 253. 
[2020-02-16 20:19:19 CET] <heinz> Diffedrent from ZX81.
[2020-02-16 20:19:40 CET] <rune> : JUP? 1 IN 1 AND ;
[2020-02-16 20:19:51 CET] <rune> first line starts with that
[2020-02-16 20:20:34 CET] <heinz> 1 IN is no IO address which is used somewhere.
[2020-02-16 20:20:50 CET] <rune> returns 1=UP 2=DOWN 4=RIGHT 8=LEFT 32=FIRE
[2020-02-16 20:20:56 CET] <heinz> IO of the keyboard is 254.
[2020-02-16 20:21:22 CET] <heinz> And the scheme of the joystick in the archive showws that 253 (A1=0) is wired.
[2020-02-16 20:21:45 CET] <rune> http://www.jupiter-ace.co.uk/hardware_joystick-AC5.html
[2020-02-16 20:21:54 CET] <rune> Are we looking at the same thing?
[2020-02-16 20:22:37 CET] <heinz> Yes, the same thing.
[2020-02-16 20:23:01 CET] <rune> The only address input I can see is A1
[2020-02-16 20:23:19 CET] <heinz> The LS368 is enable, if IORQ=0, RD=0 and A1=0.
[2020-02-16 20:23:41 CET] <heinz> A1=0 means IO=1111|1101 = 253.
[2020-02-16 20:24:11 CET] <rune> OK, so what is the 1 in the handwritten code at the bottom
[2020-02-16 20:25:03 CET] <heinz> Oh, I have overlooked that code. 
[2020-02-16 20:25:04 CET] <rune> There is also a bit where it says JOYSTICK PORT ADDRESS=1
[2020-02-16 20:25:20 CET] <heinz> But look to the scheme again.
[2020-02-16 20:25:44 CET] <heinz> There is a NAND at the left. 
[2020-02-16 20:25:55 CET] <heinz> No, NOR.
[2020-02-16 20:26:40 CET] <rune> Yes, Low RD & IORQ and High A1
[2020-02-16 20:26:52 CET] <heinz> This give 1 as output only if all three inputs are 0. Right? 
[2020-02-16 20:27:52 CET] <rune> Im trying to remember my boolean algebra
[2020-02-16 20:28:11 CET] <heinz> Your inputs would give 0 as output.
[2020-02-16 20:28:30 CET] <rune> OK, agreed
[2020-02-16 20:28:35 CET] <heinz> All three lines are equal.
[2020-02-16 20:29:11 CET] <rune> Then the second NOR has 2 at 0V + the 0 from the first NOR, so outputs a 1
[2020-02-16 20:29:28 CET] <heinz> If the output is 1, then the output of the next IC is 0.
[2020-02-16 20:29:45 CET] <heinz> Which means LS368 is enable.
[2020-02-16 20:29:46 CET] <rune> OK
[2020-02-16 20:30:44 CET] <heinz> Therefore, A1=0 is needed. 
[2020-02-16 20:30:55 CET] <heinz> Wait, 
[2020-02-16 20:31:30 CET] <heinz> the address 1 = 0000|0001 has also the property A1=0.
[2020-02-16 20:31:44 CET] <heinz> Hence 1 is also a possible address. 
[2020-02-16 20:32:23 CET] <heinz> Since I have only wired A1, my joystick would also react for 1 IN
[2020-02-16 20:32:23 CET] <rune> WOuld 253 and 1 be equivalent?
[2020-02-16 20:32:33 CET] <heinz> Yes, they are.
[2020-02-16 20:33:03 CET] <heinz> Only 0000|0000 is forbidden, 
[2020-02-16 20:33:16 CET] <heinz> since in that case the keyboard would answer.
[2020-02-16 20:33:34 CET] <heinz> Summarizing, my joystick should work.
[2020-02-16 20:33:37 CET] <rune> Have you tested the joystick response outside the games?
[2020-02-16 20:34:10 CET] <heinz> Yes, outside the games it works. 
[2020-02-16 20:34:24 CET] <heinz> And I am sure it will alos wok with 1 IN
[2020-02-16 20:34:34 CET] <rune> Then it must be the games that are incompatible
[2020-02-16 20:34:42 CET] <heinz> The only difference: fire = 16 , not 32. 
[2020-02-16 20:35:31 CET] <heinz> Wait a minute, I will plug on.
[2020-02-16 20:36:19 CET] <rune> I found Valkyr, will email to you
[2020-02-16 20:36:53 CET] <heinz> I have tried 1 IN with pressed RIGHT and got 4.
[2020-02-16 20:37:08 CET] <heinz> Will try Valkyr.
[2020-02-16 20:37:21 CET] <heinz> Do you have joysticks?
[2020-02-16 20:37:56 CET] <rune> Somewhere. I would need to look for them
[2020-02-16 20:38:13 CET] <heinz> And a a joystick IF?
[2020-02-16 20:38:38 CET] <heinz> I have used the Kempston IF for the ZX81 with some mods.
[2020-02-16 20:38:42 CET] <rune> Yes, I have a kempston compatible
[2020-02-16 20:39:02 CET] <heinz> The Kempston is wired for address 31.
[2020-02-16 20:39:19 CET] <rune> Its a cheetah model, same edge connector as Zeddy, but works on both
[2020-02-16 20:39:19 CET] <heinz> which is 0001|1111
[2020-02-16 20:39:52 CET] <heinz> You have to add the address XXXX|XX0X
[2020-02-16 20:40:01 CET] <heinz> using A1.
[2020-02-16 20:40:11 CET] <heinz> At the moment A5 is used.
[2020-02-16 20:40:11 CET] <rune> three wires and a cut?
[2020-02-16 20:40:42 CET] <heinz> I did the change in such a way that I can use the IF for both, ZX81 and ACE.
[2020-02-16 20:41:03 CET] <heinz> If you need it only for the ACE, one cut one wire.
[2020-02-16 20:41:20 CET] <rune> Will you post on the ZX TEam board?
[2020-02-16 20:42:04 CET] <heinz> The problem was that in my IF several unused pins of the address chip were connected. 
[2020-02-16 20:42:16 CET] <rune> I will look for a joystick, but vdrive commands will probably take all my attention
[2020-02-16 20:42:29 CET] <heinz> I had to isolated them by cutting the track.
[2020-02-16 20:42:39 CET] <heinz> isolate
[2020-02-16 20:42:41 CET] <rune> Is yours genuine Kempston?
[2020-02-16 20:43:03 CET] <heinz> Yes, I think so.
[2020-02-16 20:43:24 CET] <rune> Just remembered
[2020-02-16 20:43:29 CET] <heinz> It is written on the case.
[2020-02-16 20:44:10 CET] <heinz> I will try Valkyr, and then we could continue this thread.
[2020-02-16 20:44:17 CET] <rune> I have a COMCOM interface.
[2020-02-16 20:44:29 CET] <rune> OK, are you trying now?>
[2020-02-16 20:44:46 CET] <heinz> Did yoou already send?
[2020-02-16 20:45:05 CET] <rune> yes , i will check
[2020-02-16 20:45:36 CET] <rune> Yes, its gone
[2020-02-16 20:45:55 CET] <rune> Do you have problems with ZIP attachments?
[2020-02-16 20:46:33 CET] <heinz> I got it. Will try now.
[2020-02-16 20:49:57 CET] <heinz> How to get run?
[2020-02-16 20:50:03 CET] <rune> GO
[2020-02-16 20:50:04 CET] <heinz> I've loaded.
[2020-02-16 20:50:39 CET] <rune> crashes when I select KEYBOARD
[2020-02-16 20:50:42 CET] <rune> go
[2020-02-16 20:51:04 CET] <heinz> GO works.
[2020-02-16 20:51:47 CET] <rune> Goes back to OK prompt when I select Joy or Key
[2020-02-16 20:51:52 CET] <rune> vlist
[2020-02-16 20:52:15 CET] <rune> It also clears the program
[2020-02-16 20:52:22 CET] <rune> load vlakyr
[2020-02-16 20:53:48 CET] <heinz> I could start with GO, 
[2020-02-16 20:53:58 CET] <rune> Can you play it?
[2020-02-16 20:54:23 CET] <rune> I get through the instructions and setup to the point of selecting Joy or Keys
[2020-02-16 20:54:24 CET] <heinz> then I could select some options, finally J/K for joystick/keyboard. Have choosen J, ENTER.
[2020-02-16 20:54:50 CET] <heinz> But the game stops, and the program was forgotten.
[2020-02-16 20:55:00 CET] <rune> Same here
[2020-02-16 20:55:17 CET] <heinz> You've tried with keyboard?
[2020-02-16 20:55:19 CET] <rune> I edited the GO and got some graphics on screen before it locked
[2020-02-16 20:55:23 CET] <rune> Yes
[2020-02-16 20:55:44 CET] <heinz> Whrer did you get the game from?
[2020-02-16 20:55:52 CET] <heinz> where

[2020-02-16 21:00:36 CET] <heinz> I did not find the game section. 
[2020-02-16 21:00:45 CET] <heinz> Was it .tap?
[2020-02-16 21:00:50 CET] <heinz> originally?
[2020-02-16 21:01:00 CET] <rune> yes
[2020-02-16 21:01:05 CET] <heinz> Ok.,
[2020-02-16 21:01:16 CET] <heinz> Let me try tomorrow an finish for today.
[2020-02-16 21:01:17 CET] <rune> I'll load onto my drop box and send you a link
[2020-02-16 21:01:26 CET] <heinz> Yes, please.
