[2017-10-22 19:56:36 CEST] <heinz> hi all
[2017-10-22 19:57:13 CEST] <rune> hello Heinz
[2017-10-22 19:57:28 CEST] <heinz> hello dave
[2017-10-22 19:57:50 CEST] <rune> Sorry, was pulling H4th code from your 2nd ROM
[2017-10-22 19:57:54 CEST] <rune> Im back
[2017-10-22 19:58:22 CEST] <rune> Do we have a topic for tonight
[2017-10-22 19:58:27 CEST] <heinz> does the vdrive work?
[2017-10-22 19:58:53 CEST] <rune> Yes, but my edit screen is 34 characters wide which messes up the Store
[2017-10-22 19:59:27 CEST] <heinz> yes, this is a problem with hpfm.
[2017-10-22 19:59:30 CEST] <rune> I was busy until a couple of hours ago. I need to understand what is going on
[2017-10-22 19:59:57 CEST] <heinz> did you try the "aaa" pgm?
[2017-10-22 20:00:15 CEST] <rune> It crashes when I try to compile it
[2017-10-22 20:00:51 CEST] <heinz> crash or error?
[2017-10-22 20:00:55 CEST] <rune> I enter by hand, check everything, type CPL and it goes through the lines then H4th resets itselk
[2017-10-22 20:01:07 CEST] <rune> so... crash
[2017-10-22 20:01:18 CEST] <heinz> h4th or hpfm?
[2017-10-22 20:01:38 CEST] <heinz> nu1 or nu2?
[2017-10-22 20:01:39 CEST] <rune> I cant remember... possibly HMPF.
[2017-10-22 20:01:47 CEST] <rune> NU1
[2017-10-22 20:02:02 CEST] <heinz> nu1 is h4th
[2017-10-22 20:02:19 CEST] <rune> Im trying a number of different roms based on different versions.
[2017-10-22 20:02:21 CEST] <heinz> it should not crash.
[2017-10-22 20:02:56 CEST] <heinz> do you have a stable working h4th-zeddy?
[2017-10-22 20:02:56 CEST] <rune> It does... I need to stop, consolidate what I am using and retry
[2017-10-22 20:03:20 CEST] <rune> No, Im waiting for so Flash 27C64s to come
[2017-10-22 20:03:24 CEST] <rune> some
[2017-10-22 20:04:04 CEST] <heinz> do you use an emulator?
[2017-10-22 20:04:10 CEST] <rune> Yes
[2017-10-22 20:04:15 CEST] <rune> I can
[2017-10-22 20:04:18 CEST] <heinz> which one?
[2017-10-22 20:04:24 CEST] <rune> eighty one
[2017-10-22 20:04:28 CEST] <heinz> ok.
[2017-10-22 20:04:38 CEST] <heinz> take the h4th rom.
[2017-10-22 20:04:48 CEST] <heinz> boot it.
[2017-10-22 20:05:21 CEST] <heinz> i will do the same.
[2017-10-22 20:05:38 CEST] <rune> doing it
[2017-10-22 20:05:45 CEST] <heinz> edit.

[2017-10-22 20:07:18 CEST] <heinz> did fd00 come back?

[2017-10-22 20:09:07 CEST] <heinz> u.
[2017-10-22 20:09:27 CEST] <heinz> ???
[2017-10-22 20:09:38 CEST] <rune> u. shows fd00
[2017-10-22 20:09:52 CEST] <heinz> ok.

[2017-10-22 20:11:02 CEST] <heinz> top left???
[2017-10-22 20:11:23 CEST] <rune> I know I should get a character at the top left of the edit screen but there is nothing showing
[2017-10-22 20:11:57 CEST] <heinz> eighty one with h4th-rom?
[2017-10-22 20:12:10 CEST] <rune> Yes, it was working earlier
[2017-10-22 20:12:20 CEST] <heinz> try again.
[2017-10-22 20:12:24 CEST] <rune> when I was testing the HMFP rom

[2017-10-22 20:12:50 CEST] <rune> now if i type 21 FBUF ! it works
[2017-10-22 20:13:06 CEST] <heinz> top left?
[2017-10-22 20:13:29 CEST] <rune> yes when I type fbuf U. I get BD00
[2017-10-22 20:13:36 CEST] <rune> I will check RAM size
[2017-10-22 20:14:38 CEST] <rune> 32-16k but fbuf is still BD00
[2017-10-22 20:15:27 CEST] <heinz> this is a pecularity of h4th.
[2017-10-22 20:15:39 CEST] <heinz> bd00=fd00=fd00
[2017-10-22 20:16:19 CEST] <rune> Where does ram start? Is it 8K or 16K. When I disabled ram in 8-16K H4th wouldnt boot
[2017-10-22 20:16:22 CEST] <heinz> if i give fbuf i get fd00.
[2017-10-22 20:16:44 CEST] <heinz> 16k
[2017-10-22 20:16:48 CEST] <rune> Im using h4th rom supplied with eighty one
[2017-10-22 20:17:03 CEST] <heinz> try fbuf u.
[2017-10-22 20:17:34 CEST] <heinz> ???
[2017-10-22 20:17:38 CEST] <rune> Thats what I was doing. Still BD00

[2017-10-22 20:20:07 CEST] <rune> 22 BD00 ! gives a B
[2017-10-22 20:20:19 CEST] <heinz> ok.
[2017-10-22 20:20:32 CEST] <heinz> the we will take bd00.
[2017-10-22 20:20:43 CEST] <rune> ok
[2017-10-22 20:20:48 CEST] <heinz> strange.
[2017-10-22 20:21:02 CEST] <heinz> 21 bd00 shift w
[2017-10-22 20:21:28 CEST] <rune> Yes, A at top left
[2017-10-22 20:21:47 CEST] <heinz> remember: code "a"=41.
[2017-10-22 20:21:52 CEST] <heinz> try
[2017-10-22 20:22:01 CEST] <heinz> 41 bd00 shift w
[2017-10-22 20:22:21 CEST] <rune> Flashing screen
[2017-10-22 20:22:43 CEST] <heinz> this i have called the bit6-problem.
[2017-10-22 20:23:10 CEST] <rune> Because H4th uses real ascii characters rather than Sinclair codes
[2017-10-22 20:23:13 CEST] <heinz> always sutract #20 from ascii code.
[2017-10-22 20:23:34 CEST] <heinz> 21 gives a
[2017-10-22 20:23:38 CEST] <rune> Yes
[2017-10-22 20:23:45 CEST] <heinz> 22 gives b
[2017-10-22 20:24:07 CEST] <heinz> but 41 results in crash.
[2017-10-22 20:24:36 CEST] <rune> I understand. sinclair characters 0-63, 128-191
[2017-10-22 20:24:51 CEST] <rune> 64-127 has bit 7 set
[2017-10-22 20:25:07 CEST] <heinz> no.
[2017-10-22 20:25:18 CEST] <rune> No?
[2017-10-22 20:25:28 CEST] <heinz> use code number minns 32.
[2017-10-22 20:25:38 CEST] <heinz> minus 32dec
[2017-10-22 20:25:52 CEST] <heinz> or minus 20hex
[2017-10-22 20:25:53 CEST] <rune> Yes for real ascii on H4th. ZX81 codes are different
[2017-10-22 20:26:01 CEST] <heinz> right.
[2017-10-22 20:26:28 CEST] <heinz> try this experiments on your real zeddy later on.
[2017-10-22 20:26:43 CEST] <rune> I will
[2017-10-22 20:26:51 CEST] <heinz> in my nu1-rom i use fd00.
[2017-10-22 20:27:01 CEST] <heinz> at two places.
[2017-10-22 20:27:26 CEST] <rune> I saw those, I needed to change 
[2017-10-22 20:27:44 CEST] <rune> But I need to handle the extra 2 characters per line
[2017-10-22 20:27:56 CEST] <heinz> yes, look for fd00 in the txt-file.
[2017-10-22 20:28:31 CEST] <heinz> some other news?
[2017-10-22 20:28:34 CEST] <rune> Did you see my question about init?
[2017-10-22 20:28:47 CEST] <heinz> election in checoslovakia?
[2017-10-22 20:28:58 CEST] <heinz> init = prt.
[2017-10-22 20:29:10 CEST] <heinz> what was your question?
[2017-10-22 20:29:25 CEST] <rune> yes, it uses jp PRT so rest of code never completes. Is it correct
[2017-10-22 20:31:20 CEST] <heinz> why not complete?
[2017-10-22 20:31:58 CEST] <rune> Well PRT has a return, so INIT jumps there and PRT returns. Code after JP PRT and the ret of of init doesnt run?
[2017-10-22 20:33:20 CEST] <heinz> the code after jp prt belongs to "send"
[2017-10-22 20:33:29 CEST] <heinz> different story.
[2017-10-22 20:33:39 CEST] <rune> OK, my bad. 
[2017-10-22 20:33:48 CEST] <heinz> init and prt do the following:
[2017-10-22 20:34:49 CEST] <heinz> they just receive bytes from the vdrive, display them, and repeat it until > is found.
[2017-10-22 20:35:14 CEST] <heinz> > belongs to the prompt sequence d:/>
[2017-10-22 20:35:34 CEST] <heinz> the prt and init do ret.
[2017-10-22 20:35:50 CEST] <rune> OK, modified my notes. I sometimes get D:\>D:\>D:\>
[2017-10-22 20:36:06 CEST] <rune> I see czech election changed winning parties. But I dont know what they are, left - centre - right
[2017-10-22 20:36:34 CEST] <heinz> this shows that you gave a lot of commands without reading back from vdrive.
[2017-10-22 20:37:08 CEST] <heinz> did you get the list of ecs for vdrive?
[2017-10-22 20:37:13 CEST] <rune> OK, I am rewriting my notes and checking ROMs
[2017-10-22 20:37:22 CEST] <rune> ECS?
[2017-10-22 20:37:38 CEST] <heinz> extended command set
[2017-10-22 20:37:48 CEST] <rune> Using your 2nd rome, I can INIT, DIR, VSTORE, VLOAD
[2017-10-22 20:37:49 CEST] <heinz> it was a jpg.
[2017-10-22 20:37:56 CEST] <rune> Yes, I got those yesterday?
[2017-10-22 20:38:02 CEST] <heinz> yes.
[2017-10-22 20:38:21 CEST] <rune> But the VStore saves the code and a load of other stuff.
[2017-10-22 20:38:44 CEST] <rune> I even got a good boot screen before it melted tonight
[2017-10-22 20:39:39 CEST] <heinz> did you try he command send?
[2017-10-22 20:39:46 CEST] <heinz> the
[2017-10-22 20:40:23 CEST] <rune> No, I ihave a lot of work outside to do this weekend., I just finished 2 hours ago
[2017-10-22 20:40:51 CEST] <heinz> you are tired?
[2017-10-22 20:41:05 CEST] <heinz> next week again?
[2017-10-22 20:41:11 CEST] <rune> All I did was try my modified rom, then reburnt the 2nd one yuou gave me
[2017-10-22 20:41:33 CEST] <rune> IM not tired, sore back. I have been laying 50Kg paving slabs
[2017-10-22 20:41:45 CEST] <rune> Yes, every week as long as you want to talk
[2017-10-22 20:41:58 CEST] <heinz> try printing on screen and find the right address.
[2017-10-22 20:42:22 CEST] <rune> I will, what is best way to read the screen?
[2017-10-22 20:42:37 CEST] <rune> FBUF @ U.
[2017-10-22 20:42:37 CEST] <heinz> same trick:
[2017-10-22 20:43:04 CEST] <heinz> bd00 shift e emit
[2017-10-22 20:43:59 CEST] <heinz> not right.
[2017-10-22 20:44:16 CEST] <rune> OK, but the char is wrong. Poss need to suntract 20
[2017-10-22 20:44:30 CEST] <heinz> right.
[2017-10-22 20:44:48 CEST] <heinz> bd00 shift e 20 + emit
[2017-10-22 20:45:03 CEST] <rune> OK, I will stop and relax a bit before bed.
[2017-10-22 20:45:13 CEST] <rune> Talk next week.
[2017-10-22 20:45:14 CEST] <heinz> next sunday?
[2017-10-22 20:45:18 CEST] <heinz> ok.
[2017-10-22 20:45:20 CEST] <heinz> bye
[2017-10-22 20:45:28 CEST] <rune> Here is a question to think about
[2017-10-22 20:45:46 CEST] <heinz> im hearing
[2017-10-22 20:45:47 CEST] <rune> Is it possible to have a routine to load additional commands into RAM?
[2017-10-22 20:46:03 CEST] <heinz> yes, it is.
[2017-10-22 20:46:07 CEST] <rune> and still have dictionary work if its not called
[2017-10-22 20:46:13 CEST] <heinz> yes.
[2017-10-22 20:46:30 CEST] <heinz> bokje did this with plot
[2017-10-22 20:46:36 CEST] <rune> OK, maybe you can email me about that one please
[2017-10-22 20:46:56 CEST] <heinz> ill do.
[2017-10-22 20:47:01 CEST] <heinz> be
[2017-10-22 20:47:03 CEST] <rune> OK, next week then.
