[2017-10-15 20:00:28 CEST] <rune> hello heinz
[2017-10-15 20:01:11 CEST] <heinz> hello dave
[2017-10-15 20:01:28 CEST] <rune> hi, good news this side
[2017-10-15 20:01:45 CEST] <rune> h4th runs great on NU
[2017-10-15 20:01:49 CEST] <heinz> tell m
[2017-10-15 20:01:52 CEST] <heinz> me
[2017-10-15 20:02:05 CEST] <heinz> 8k?
[2017-10-15 20:02:23 CEST] <rune> the version i found on zx team forum
[2017-10-15 20:02:33 CEST] <rune> yes
[2017-10-15 20:02:38 CEST] <heinz> the hmfp?
[2017-10-15 20:02:57 CEST] <rune> yes, if ha FF at1FFF
[2017-10-15 20:03:01 CEST] <heinz> written by gert?
[2017-10-15 20:03:29 CEST] <rune> dont know
[2017-10-15 20:03:49 CEST] <heinz> it has a4 at 2000?
[2017-10-15 20:04:38 CEST] <heinz> this marks a rom extension by 8k more.
[2017-10-15 20:04:38 CEST] <rune> i just needs routines for vdrive
[2017-10-15 20:05:03 CEST] <rune> I ignored that
[2017-10-15 20:05:16 CEST] <heinz> the vdrive is not as easy.
[2017-10-15 20:05:40 CEST] <heinz> how do you want to connect the vdrive?
[2017-10-15 20:05:49 CEST] <rune> standard nu?
[2017-10-15 20:06:24 CEST] <heinz> in this case you have to use the rom- file i ve sent.
[2017-10-15 20:07:08 CEST] <rune> one of the roms you sent is very different
[2017-10-15 20:07:11 CEST] <heinz> the vdrive drivers replace the tape loading routines.
[2017-10-15 20:07:28 CEST] <rune> do you have addresses
[2017-10-15 20:07:58 CEST] <heinz> i mean that rom with he menu zx81/forth.
[2017-10-15 20:08:31 CEST] <fuzb> hello gentlemen
[2017-10-15 20:08:52 CEST] <rune> I only checked the single rom with vdrive
[2017-10-15 20:09:10 CEST] <rune> heh fuzb
[2017-10-15 20:09:13 CEST] <heinz> did it work?
[2017-10-15 20:09:18 CEST] <rune> no
[2017-10-15 20:09:22 CEST] <heinz> hi fuzb
[2017-10-15 20:09:30 CEST] <fuzb> tomorrow I will visit hamburg
[2017-10-15 20:09:51 CEST] <heinz> niceheather in grmany now.
[2017-10-15 20:10:00 CEST] <heinz> wheather
[2017-10-15 20:10:07 CEST] <fuzb> I bet it will be better than in FI
[2017-10-15 20:10:19 CEST] <fuzb> 4 degrees C now
[2017-10-15 20:10:54 CEST] <rune> Its wet here
[2017-10-15 20:11:12 CEST] <heinz> 23 degrees in berlin.
[2017-10-15 20:11:22 CEST] <fuzb> it will be like finnish summer in there, probably
[2017-10-15 20:11:23 CEST] <heinz> sunny.
[2017-10-15 20:11:31 CEST] <rune> Ill email with detail re vdrive rom
[2017-10-15 20:12:12 CEST] <heinz> dave: there are two different ways using the vdrive.
[2017-10-15 20:12:32 CEST] <rune> on the nu?
[2017-10-15 20:12:55 CEST] <heinz> 1st take a zx81 with h4th rom and an external vdrive.
[2017-10-15 20:13:53 CEST] <heinz> 2nd on nu with internal vdrive and the rom i had sent to you.
[2017-10-15 20:15:20 CEST] <heinz> this last one has 32kb
[2017-10-15 20:15:51 CEST] <heinz> the first way uses a 16k rom.
[2017-10-15 20:16:23 CEST] <rune> How do you burn that on eprom
[2017-10-15 20:16:33 CEST] <rune> for the nu
[2017-10-15 20:16:51 CEST] <heinz> i dont understand why the screen driver dont work correct.
[2017-10-15 20:17:38 CEST] <heinz> for the nu you need the 32k rom with olis menu zx81/forth.
[2017-10-15 20:18:22 CEST] <rune> 1 rom had addresses near 64k, 1 that works has same addresses near 32k
[2017-10-15 20:18:33 CEST] <heinz> do you have a working nu with the zx80/zx81 rom?
[2017-10-15 20:19:15 CEST] <rune> Every H4th rom before the las tdidnt work
[2017-10-15 20:19:36 CEST] <heinz> answer my question.
[2017-10-15 20:19:45 CEST] <rune> Yes
[2017-10-15 20:19:52 CEST] <heinz> 32kb?
[2017-10-15 20:20:05 CEST] <rune> 64k
[2017-10-15 20:20:16 CEST] <heinz> mirrored?
[2017-10-15 20:20:20 CEST] <rune> yes
[2017-10-15 20:20:26 CEST] <heinz> 2x32kb?
[2017-10-15 20:20:38 CEST] <rune> yes
[2017-10-15 20:20:57 CEST] <heinz> vdrive is working with them?
[2017-10-15 20:21:35 CEST] <rune> Yes on zx80/81
[2017-10-15 20:21:40 CEST] <heinz> ok.
[2017-10-15 20:21:48 CEST] <heinz> what ram?
[2017-10-15 20:22:00 CEST] <rune> 32k or 64k
[2017-10-15 20:22:05 CEST] <heinz> ok.
[2017-10-15 20:22:32 CEST] <rune> Ollies
[2017-10-15 20:22:57 CEST] <rune> ollies rom did work on zx81 or nu properly
[2017-10-15 20:23:07 CEST] <heinz> take this machine, put a 32k ram in it, burn an 27c256(32kb) wih the rom i have sent ant try.
[2017-10-15 20:23:11 CEST] <rune> or h4th
[2017-10-15 20:23:27 CEST] <rune> doesnt work
[2017-10-15 20:23:56 CEST] <rune> Both have display problems
[2017-10-15 20:25:47 CEST] <heinz> the name of the rom was very long: nu-zx81-h4th-vdr-oli2017-256.bin
[2017-10-15 20:26:31 CEST] <rune> yes 
[2017-10-15 20:27:06 CEST] <heinz> it should work.
[2017-10-15 20:27:08 CEST] <rune> doesnt work - display problems , 
[2017-10-15 20:27:19 CEST] <heinz> i will send it again.
[2017-10-15 20:27:25 CEST] <rune> incompatible with mr x
[2017-10-15 20:28:18 CEST] <heinz> mrx: depending on the addresses you re using.
[2017-10-15 20:28:33 CEST] <rune> how do you change address
[2017-10-15 20:28:56 CEST] <rune> i did not see any jumper
[2017-10-15 20:31:12 CEST] <heinz> the addresses are defined by the gal-functions.
[2017-10-15 20:31:39 CEST] <rune> ok, the mrx is fine with the last eprom
[2017-10-15 20:32:12 CEST] <heinz> there was a preversion of the h4th-rom for nu without vdrive.
[2017-10-15 20:32:50 CEST] <heinz> i ll try to find this rom image. try this, and the picture should be clea.
[2017-10-15 20:32:56 CEST] <heinz> clear.
[2017-10-15 20:33:22 CEST] <rune> The last h4th rom i got is perfect , just no vdrive
[2017-10-15 20:34:48 CEST] <heinz> is this gert s rom?
[2017-10-15 20:35:00 CEST] <rune> yes, i think so
[2017-10-15 20:35:29 CEST] <heinz> did you try plot?
[2017-10-15 20:36:09 CEST] <rune> no, just got it running this afternoon
[2017-10-15 20:36:27 CEST] <heinz> where did you find it?
[2017-10-15 20:36:40 CEST] <rune> on tlienhart forum
[2017-10-15 20:36:49 CEST] <heinz> more preciely
[2017-10-15 20:37:08 CEST] <rune> cant remember hold on 
[2017-10-15 20:38:22 CEST] <rune> dogs pulled the vmouse out searching difficult
[2017-10-15 20:38:39 CEST] <heinz> wait.
[2017-10-15 20:43:13 CEST] <heinz> i found it.
[2017-10-15 20:43:45 CEST] <rune> So did I - had to get the mouse working again first
[2017-10-15 20:43:57 CEST] <heinz> it is the thread h4th for zxmore from nov 4,2016.
[2017-10-15 20:44:54 CEST] <rune> Yep, that ROM works perfectly. Everything before either didnt work or had big problems with the display
[2017-10-15 20:45:24 CEST] <rune> I just used first 8K, 
[2017-10-15 20:45:51 CEST] <heinz> look to the post from febr 2nd, 2017
[2017-10-15 20:46:26 CEST] <rune> What to search on?
[2017-10-15 20:46:29 CEST] <heinz> did you use this rom in the nu?
[2017-10-15 20:46:37 CEST] <rune> Yes
[2017-10-15 20:46:42 CEST] <rune> perfect
[2017-10-15 20:46:53 CEST] <heinz> title h4th for zxmore.
[2017-10-15 20:46:58 CEST] <rune> What to search for fen 2nd post
[2017-10-15 20:47:31 CEST] <heinz> you will find the command 43 0 do i i plot loop
[2017-10-15 20:47:40 CEST] <heinz> this plots a line.
[2017-10-15 20:48:28 CEST] <rune> I see that post
[2017-10-15 20:48:39 CEST] <heinz> the thread starts on oct 20, 2016
[2017-10-15 20:49:14 CEST] <rune> got it, is there any way to get VDrive routines into that ROM?
[2017-10-15 20:49:23 CEST] <heinz> no.
[2017-10-15 20:50:02 CEST] <rune> Why? I thought you said it was possble to overwrite the tape Save and Load routines
[2017-10-15 20:51:00 CEST] <heinz> yes, but you have to plug in the patch in a very involved way.
[2017-10-15 20:51:30 CEST] <heinz> i could send you the source text and you could try to do it.
[2017-10-15 20:51:45 CEST] <rune> Surely if the patch has a start and end address, its a matter of using a hex editor?
[2017-10-15 20:51:56 CEST] <rune> Please, any clues are welcome
[2017-10-15 20:52:51 CEST] <rune> One thing I did notice was the difference between gerts rom and the last one you sent were addresses. Gerts seemed to use just below 32K, yours were just below 64K
[2017-10-15 20:53:27 CEST] <heinz> you have also to study the structure of h4th and change some more addresses . you have to cut a hread and to connect it from new.
[2017-10-15 20:54:06 CEST] <rune> OK, this is something I want to work so am prepared to put the effort in
[2017-10-15 20:54:23 CEST] <heinz> do you mean the address fd00?
[2017-10-15 20:54:34 CEST] <heinz> vesus 7d00?
[2017-10-15 20:54:58 CEST] <rune> Yes, FD and 7D, not 00 though
[2017-10-15 20:55:24 CEST] <rune> I have disassembly of both ROMs and can compare line by line
[2017-10-15 20:55:59 CEST] <heinz> did you run this rom on nu?
[2017-10-15 20:56:40 CEST] <rune> I ran both, FD address didnt work, just black screen. 7D does work very well.
[2017-10-15 20:57:40 CEST] <rune> There are other differences too, but these are most common
[2017-10-15 20:58:59 CEST] <heinz> try to implement my patch from #1501 - #1675.
[2017-10-15 20:59:39 CEST] <rune> OK, will do
[2017-10-15 21:00:16 CEST] <heinz> i will send you a short instruction.
[2017-10-15 21:00:38 CEST] <heinz> and stop for today.
[2017-10-15 21:00:44 CEST] <rune> Thanks, one more short question. Is it possible to use a 16K rom with ZX NU
[2017-10-15 21:01:11 CEST] <heinz> i dont know, dont believe.
[2017-10-15 21:01:19 CEST] <rune> OK, it has been very informative tonight.
[2017-10-15 21:01:21 CEST] <heinz> the nu ues 4x8k.
[2017-10-15 21:01:52 CEST] <rune>               I have 10 Flash ROMs ordered
[2017-10-15 21:02:07 CEST] <heinz> uses
[2017-10-15 21:02:08 CEST] <rune> ... from China :( Long wait
[2017-10-15 21:02:23 CEST] <rune> OK, we finish now?
[2017-10-15 21:02:24 CEST] <heinz> be pationed.
[2017-10-15 21:02:32 CEST] <heinz> yes, finish.
[2017-10-15 21:02:40 CEST] <heinz> bye.
[2017-10-15 21:02:41 CEST] <rune> Talk to you later, bye
