mntmnisoriano_: good morning, i can tell you a shortcut to get your card in 3-4 days if you promise not to cancel your other order with us ;)14:23
mntmnisoriano_: interested?14:23
_BnuIt involves lasers, hedge trimmers and killer snails...17:25
mntmnapparently not interested ;317:27
_BnuKiller snails always deters people from getting ZZ9000s faster... maybe it needs to be changed to escargots.17:40
mntmnhehe17:41
apolkosnik[m]Also, wives... 18:51
mntmna classic trope18:51
apolkosnik[m]Followed by goats and pigeons 18:54
_Bnumntmn: What if you were to set something up that "races behind the beam" to copy the current data on an APC-enabled path to a set frame buffer position somewhere in memory right after the current pixels have been rendered to screen... Doesn't matter for scandoubler output, of course, but it might allow for displaying the current frame buffer without any kind of cache line artifacting?20:04
_Bnu(Yep, I'm still trying to come up with something to get rid of the data-destroying cache flush...)20:05
mntmni am sure we can fix the data destruction differently20:14
mntmnfirst, i need a test program that reproduces it reliably20:14
isoriano_Guys .. I have to earn some money :-) Always interested now that I finished my retro room :-)21:27
mntmnisoriano_: here you go! https://www.amiga-shop.net/Amiga-Hardware/Amiga-Grafikkarten/ZZ9000-Multifunktionskarte-fuer-Zorro-Amigas::1011.html21:28
isoriano_Hmm ..21:29
mntmnisoriano_: hmm?21:30
isoriano_Why from a third party if I can buy from you? Just because he has it in stock? 21:31
mntmnyeah. i thought you wanted it very quickly21:32
mntmnnaja on the other hand i think you are in our next batch21:32
isoriano_yeah .. waiting 5 months .. a few weeks won't kill me. 21:32
isoriano_And the A3K has its ZZ .. just the A4K is waiting for the upgrade ..21:33
mntmnyeah, you actually are. so probably 2 weeks to go21:33
isoriano_Btw .. don't if it will work .. but I reached out to one of my AMIGA colleagues if he can help me with doing kind of a ZZ for the SBus I hope that you don't mind if we can learn from your work and try doing a "port" to the Sun.21:35
isoriano_Well it's kind of ZYNQ-7020 SBus carrier board.21:37
mntmnof course i would prefer if people would instead help me improve ZZ for amiga, but do whatever you like!21:37
isoriano_The AMIGA community is huge so many people working on projects while there is no love for the Sun. 21:38
mntmnok then!21:39
mntmnright now it's kind of hard to develop new hardware btw, because a lot of chips are out of stock21:39
mntmnbecause of the global component shortage21:39
isoriano_Tried to acquire some MYIR boards remember when you provided the tip and I bought just a single board ... now they nearly doubled the price.21:40
mntmnyes. the network chip on that module costs $35 now. per piece. at least. from chinese brokers21:40
mntmnit's insane21:40
isoriano_35?? Oh Mann!21:40
mntmnyes, the first offers i got were 60-80$21:40
mntmnso $35 is still cheap21:41
mntmni think i will increase the price of zz9000 now21:41
mntmnbefore it's too late21:42
isoriano_Sure! 21:42
isoriano_People are aware of the market situation.21:43
mntmnyeah21:47
mntmni increased the price to 38921:48
mntmnhaha jens also going with UPS now https://icomp.de/shop-icomp/en/33/items/new-shipping-option-ups.html21:49
isoriano_Which is still a fair price for the ZZ.21:53
mntmnXC7Z020 is not really available atm21:54
mntmnsupposed to come back april 202221:55
mntmnso i will move our delivery date to that point21:55
isoriano_OMG!!!!!21:55

mntmn> Lagerbestand: 122:08
mntmnhmm that's game over for us22:11
isoriano_https://de.aliexpress.com/item/32988738790.html22:17
mntmnwell that's a useless form factor22:18
mntmnthere are a lot of snickerdoodles in stock, but they are very expensive https://www.mouser.de/ProductDetail/krtkl/15081800-04?qs=byeeYqUIh0O%2FK1dGah2FrA%3D%3D22:19
isoriano_i hope that you have at least some stock wrt the fpga modules ..22:25
mntmni think we have 30-40 and also some broken ones. with those we will fill existing orders.22:29
mntmnthen we will see how many we can get from somewhere, if none, we will offer refunds22:29
mntmni hope my supplier will respond tomorrow22:29
mntmnthe controller for the keyboards we make is also out of stock now.22:30
mntmni can close the company basically22:30
mntmnnaja we will see. need to evaluate all options. but this is really a bad situation.22:30
mntmnwell i will go home.22:36
isoriano_Verdammt! that does not sound promising! And if you need to fullfil an order for someone impatient you can take my ZZ .. I have one in my A3K .. so the A4K can wait (would have to wait). 22:36
mntmnthanks!22:36
+ xet7 (~xet7@user/xet7)22:39
_Bnumntmn: ('A`)23:28
mntmnmaybe we can develop an intermediate module instead of the zynq thing23:29
_BnuMaybe you can make MNT branded PiStorms... though I don't know how profitable that would be... maybe a bit more once we can get it working in additional 68k systems.23:29
mntmnthat does some of the zz stuff and later exchange it when the real deal comes back23:29
mntmn_Bnu: i have thought about it, but what about the pi3 (??) supply?23:30
mntmndo they have many stonks?23:30
_BnuI think there's still like a few ten thousands left, but Claude's working on a new firmware as well that works with the Pi 4 and CM4.23:30
_BnuRaffles (a guy on the Discord server) designed a prototype for a custom PCB as well, let me dig up a picture.23:31
isoriano_CM4 is what? About 50 EUR?23:31
_Bnuhttps://cdn.discordapp.com/attachments/836236986443890710/865677849829441556/DSC_1575.JPG23:31
mntmnisoriano_: cm4 is not the one for pistorm. also it needs a large amount of power23:32
_BnuYeah, there's a connector for extra power on Raffles' PCB.23:32
mntmnooof ok23:32
mntmnquite the chonker23:32
_BnuThe CM4 works okay with one of those Polish C64PSU power supplies, at least for basic CPU emulation, but yeah... it gets very hot, haha.23:33
_BnuStill beats a 50MHz 060 by a good margin while thermal throttling.23:33
mntmnsoon every computer will be a cm4??23:34
mntmnbtw i ordered a cm4 today23:34
mntmnbut not all versions were available23:35
_BnuYeah, I think the lowest RAM version was retired or something?23:35
_BnuBecause no one wanted it anyway . . .23:36
mntmnyeah i mean some combinations were not available atm23:36
mntmnhmm interesting23:36
mntmnthat was the 1GB version that you mean23:36
_BnuYeah, I think so at least.23:36
mntmni could certainly do something like ice40 or ecp5 for zorro and videocap plus imxrt or some sort of ripsberry raps but idk in what kind of timeframe23:41
mntmnhow does the pistorm bus translation work? with a cpld? and then to spi or custom parallel something? i mean how does the cpld talk to the pi?23:42
_BnuClaude would probably be better fit to explain it than I, or shanshe, I only know how to interface with it from the software side, haha.23:43
_BnuThe current protocol isn't super effective or complete, but it tends to work well enough for Amiga.23:43
_BnuBut basically the CPLD keeps track of all the CPU pins, since the Pi itself doesn't have enough GPIO to do that.23:46
_BnuAnd then on the Pi side you can grab/put stuff from/on the data lines, set the address lines, and read the status register for things like the IPL.23:47
mntmnah i just read the verilog23:52
mntmni see23:52
mntmnso there is a 16 bit gpio bus to the pi23:53
mntmnand two mode bits23:53
mntmnand 6 control bits23:53
mntmncool cool23:54
