[2020-01-05 19:58:00 CET] <heinz> Hello Dave
[2020-01-05 19:58:09 CET] <rune> hello heinz
[2020-01-05 19:58:25 CET] <rune> I may have found a problem with the ACE
[2020-01-05 19:58:35 CET] <heinz> Does it run?
[2020-01-05 19:58:37 CET] <rune> I was trying different Z80s
[2020-01-05 19:58:42 CET] <rune> Not yet
[2020-01-05 19:59:06 CET] <rune> Some z80 worked others sometimes and one always but the screen is astill a mess
[2020-01-05 19:59:22 CET] <rune> So I tried continuity around the resistor on the Z80
[2020-01-05 19:59:38 CET] <rune> It looks like pin 10 and 17 are connected.
[2020-01-05 19:59:44 CET] <heinz> Do you remember, there was a crossing point in the scheme which became a joint on your board.
[2020-01-05 19:59:50 CET] <rune> Pin 10 is D6
[2020-01-05 19:59:58 CET] <rune> Yes
[2020-01-05 20:00:13 CET] <rune> but I did all the cutr
[2020-01-05 20:00:16 CET] <rune> cuts
[2020-01-05 20:00:20 CET] <heinz> Is this crossing really in order?
[2020-01-05 20:00:29 CET] <rune> Im sure it is, but I will check
[2020-01-05 20:00:35 CET] <heinz> Did you measure with a meter?
[2020-01-05 20:00:38 CET] <rune> Yes
[2020-01-05 20:00:43 CET] <heinz> ok.
[2020-01-05 20:01:01 CET] <heinz> So, connection between D6 and pin17?
[2020-01-05 20:01:04 CET] <rune> I used the DIODE tester with buzzer on which I think is continuity
[2020-01-05 20:01:11 CET] <rune> Looks like it
[2020-01-05 20:01:30 CET] <heinz> buzzer is very good tool.
[2020-01-05 20:02:00 CET] <rune> Im opening schema and PCB design for ace
[2020-01-05 20:02:09 CET] <rune> But it has the mods...
[2020-01-05 20:03:17 CET] <heinz> What about pin10 and 17?
[2020-01-05 20:03:22 CET] <rune> Pin 10 goes to Eprom, 1st RAM
[2020-01-05 20:04:03 CET] <heinz> pin17 is NMI. Should have contact witzh no other pin.
[2020-01-05 20:04:08 CET] <rune> That has resistor between I checked all adjacent pins and no short. But tonigh I chacked 17-11 and 17-10
[2020-01-05 20:05:29 CET] <rune> Pin 17 has the resistor to Pin 11
[2020-01-05 20:05:36 CET] <rune> No? Yes?
[2020-01-05 20:06:15 CET] <rune> Its hewld high with 5V
[2020-01-05 20:06:52 CET] <heinz> That is right. The pullup res for /NMI.
[2020-01-05 20:07:15 CET] <heinz> You spoke about pin17 and pin 10.
[2020-01-05 20:07:32 CET] <heinz> You spoke about pin 10 and pin 17.
[2020-01-05 20:07:43 CET] <rune> Yes, I was checking and thought to do 17 and 10. 
[2020-01-05 20:07:51 CET] <rune> And got continuity
[2020-01-05 20:08:22 CET] <rune> I realised that it shouldnt connect
[2020-01-05 20:08:59 CET] <heinz> The 10k res 17-11 will not allow to ring  the buzzer.
[2020-01-05 20:09:30 CET] <rune> It doesnt, but 10-17 does
[2020-01-05 20:09:37 CET] <heinz> Really?
[2020-01-05 20:09:45 CET] <heinz> Check again.
[2020-01-05 20:10:15 CET] <rune> OK, I cant just now. 
[2020-01-05 20:10:45 CET] <rune> Everything is put away
[2020-01-05 20:11:30 CET] <rune> But if the solder joint at 11 did touch 10 it shouldnt buzz
[2020-01-05 20:11:40 CET] <rune> so problem may be somewhere else
[2020-01-05 20:12:22 CET] <heinz> Check also connection between 10 and 11. 
[2020-01-05 20:12:37 CET] <rune> I did, there isnt one
[2020-01-05 20:12:58 CET] <rune> Its strange, I think I need to check at eprom and ram
[2020-01-05 20:14:34 CET] <rune> do you need soe ace programs
[2020-01-05 20:14:42 CET] <rune> some
[2020-01-05 20:15:53 CET] <heinz> If I look onto the pcb-topbot.png I can't see any track starting at pin 17.
[2020-01-05 20:16:34 CET] <heinz> ACE programs: Yes, I have collected some from the ACE site 
[2020-01-05 20:16:44 CET] <rune> https://archive.org/details/Jupiter_Cantab_Jupiter_Ace_TOSEC_2012_04_23
[2020-01-05 20:16:52 CET] <rune> theres a link
[2020-01-05 20:16:53 CET] <heinz> This one.
[2020-01-05 20:17:18 CET] <heinz> Most of them are of type tzx, but now I know how to convert them into tap.
[2020-01-05 20:17:36 CET] <heinz> Found adventures and games.
[2020-01-05 20:17:40 CET] <rune> these are wav ,tap and ace
[2020-01-05 20:18:01 CET] <rune> lots of utilies apss agames and demos
[2020-01-05 20:18:24 CET] <rune> dont know what .ace is or how its used
[2020-01-05 20:19:32 CET] <heinz> Oh, I did not know this site.
[2020-01-05 20:20:10 CET] <rune> archive.org? its got lots of everything

[2020-01-05 20:20:31 CET] <heinz1> Sorry, interrupt.
[2020-01-05 20:21:04 CET] <rune> tosec have archives of all the 8 bit computer and console software
[2020-01-05 20:21:21 CET] <heinz1> .ace is explained on Jupiter-Ace Resource
[2020-01-05 20:21:42 CET] <rune> ok, i'll check it
[2020-01-05 20:22:11 CET] <heinz1> Dave, 
[2020-01-05 20:22:16 CET] <heinz1> I got a cold.
[2020-01-05 20:22:17 CET] <rune> yes
[2020-01-05 20:22:24 CET] <rune> ok, short night
[2020-01-05 20:22:30 CET] <heinz1> So don not feel very weel now.
[2020-01-05 20:22:34 CET] <rune> get a whisky and bed
[2020-01-05 20:22:34 CET] <heinz1> well
[2020-01-05 20:22:48 CET] <rune> talk to u later keep well
[2020-01-05 20:22:53 CET] <heinz1> bed is good, whiskey ios not the best idea.
[2020-01-05 20:23:03 CET] <rune> bye ;)
[2020-01-05 20:23:11 CET] <heinz1> Talking next Sunday?
[2020-01-05 20:23:20 CET] <heinz1> Bye
[2020-01-05 20:23:22 CET] <rune> yes, email before that
[2020-01-05 20:23:28 CET] <heinz1> ok
