00:46 rue_house oooh I understand, the displacor moves the air between the hot and cold sides to alternate the heat of it and thus the volume of it
00:46 rue_house http://www.youtube.com/watch?v=Ow_mBbd2jWU
00:48 tsmeow-afk guesses it's a ster
00:48 rue_house a pringles one
00:48 rue_house full build video
00:49 katsmeow-afk isn't the basic sterling less useful because it takes money to make it both efficient and last long?
00:49 katsmeow-afk did you see the one with the liquid displacer? still needs a solid power piston tho
00:53 katsmeow-afk according to Chinese research, Corydalis has an analgesic effect approximately 1 % that of the strength of opium
01:02 katsmeow-afk i think what we need is a piston steam engine with as little stroke as possible
01:03 katsmeow-afk i say that mostly because if you have a 1/2 inch stroke piston with 100psi on it, you have the same push as if it was a 10inch stroke with 100psi on it
01:03 katsmeow-afk the difference is the 9.5 inches of extra stroke holds 100psi that isn't helping you
01:04 katsmeow-afk this is why triple expander engines gain their efficency
01:06 katsmeow-afk the 2nd piston takes that 100psi and lowers it to 50 psi, then the 3rd piston lowers it to 20psi
01:07 katsmeow-afk now if you can figure a way to have a vertical cylinder with a liquid piston and valves that open at the bottom at difefrent pressures to feed different hydraulic motors, it would be uber efficient, and very programmable
01:09 katsmeow-afk ok, i go away
01:09 katsmeow-afk i dunno why i cannot say anything useful anymore
01:40 rue_house you are, I'm just being quiet
01:40 rue_house I usualy read most of your stuff
01:40 rue_house sometimes I miss some
01:42 katsmeow-afk you see what i said about using all those 1200 80ns sdrams?
01:42 katsmeow-afk they aren't 80ns read cycle, they are 80ns clock cycle tme, it takes at least 3 clocks to read or write
01:43 katsmeow-afk so they are actually, for single random reads or writes, 240ns rams
01:43 rue_house whats static? like 80ns isn't it?
01:44 katsmeow-afk but if i put them in so they are 128bytes wide, i can chop them into 8 vliw sections, and the overall sequential read time is only 30ns
01:44 katsmeow-afk statics almost always say what their read or write access time is, some say what teh read or write cycle time is
01:45 katsmeow-afk but sdrams say what their CLOCK cycle time is
01:47 katsmeow-afk for your puter cpu to write a single byte of ram with 800Mhz ddr3 sdram, takes *at_least* 3 clocks, each 1/800ns, so the ram is actually absorbing the random writes at 800/3 = 200Mhz
01:47 katsmeow-afk so i have pounds of rams from the cablebox mobo i wanna use
01:48 katsmeow-afk i also have pounds of 128meg, 256meg, 512meg sdram modules
01:49 rue_house you know my oppinion of dram :) its only cause I couldn't get it going when I started out
01:49 katsmeow-afk the ram chips from the modules before ddr3 is all j-lead, easy to remove and reinstall on your own pcbs
01:50 katsmeow-afk 128meg modules have 16Mbyte chips
01:50 katsmeow-afk etc
01:56 rue_bed are they 4, 8, 9, or 16 bit?
01:56 katsmeow-afk which?
01:56 katsmeow-afk the rams on the modules are all 8bit
01:57 katsmeow-afk the sdram from the cableboxes is mixed some 8, some 16, some 8/16
02:02 tsmeow-afk goes to put her paws in the FootToa
02:04 katsmeow-afk WASHINGTON -- As the Obama administration considers ending the storage of millions of phone records by the National Security Agency, the government is quietly funding research to prevent eavesdroppers from seeing whom the U.S. is spying on, The Associated Press has learned.
02:04 katsmeow-afk http://www.pbs.org/newshour/rundown/2014/01/us-launches-five-research-teams-to-develop-new-covert-data-mining-methods.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+TheRundownNewsBlog+%28The+Rundown+News+Blog%29
02:06 rue_bed but nobody working for it will get paid because the usa is bankrupt
02:08 rue_bed which will come up again next month when they remove the 'silly debt cieling' cause 'really, what does it matter if we can or cant pay back that money anyhow?'
02:08 rue_bed just because the usa is completely unable to pay even the interest on its debt...
02:09 rue_bed I'm sure china would NEVER try to claim US soil as debt payment
14:55 katsmeow-afk <China> you owe us $4 Trillion , yo can pay us by handing to us all your US Navy ships, or we will blockade you like you did to Iran and N Korea and Cuba
14:56 katsmeow-afk Iran has ships in the Atlantic now, and states they will have them routinely patrolling off the usa east coast by the end of 2014
15:05 katsmeow-afk ========
15:05 katsmeow-afk It seems FedEx is using the USPS to deliver packages, the FedEx site says "Customer not available or business closed - Please contact local Post Office to pick up or reschedule delivery". I can assure you i have not left my home since Monday, when i had to goto the Post Office to pick up another package they refused to deliver.
15:05 katsmeow-afk If you cannot get them to deliver the package, they might return it to you, and you can re-send it UPS. Basically, i want the items delivered to me as i paid for.
15:05 katsmeow-afk ========
15:50 katsmeow-afk rue, FedEx now uses USPS for last-mile delivery... "Includes Package Pickup4, tracking information with USPS Tracking, and $100 in insurance with additional insurance available up to $2,499." <<== i can guarantee you it will not be delivered, and that will cost me non-compliance with my return delivery to you
15:52 katsmeow-afk crap ==>> http://about.usps.com/publications/pub141/postage-and-fees.htm#Money-BackGuarantee
15:52 katsmeow-afk they can still simly refuse todeliver it
16:02 katsmeow-afk 38 minutes on the phone to USPS
17:11 katsmeow-afk Please consider one of these possible solutions related to your query
17:11 katsmeow-afk Solutions to consider
17:11 katsmeow-afk What Postal Terms Begin with the Letter �S"?
17:11 katsmeow-afk What Postal Terms Begin With the Letter �P"?
17:21 katsmeow-afk most of the radio stations in Bham are linked and simulcasting "wrecks on the highway" call-in show
17:42 katsmeow-afk Can you get this package to me, or should i buy new items from someone else? I am not going to wait 3 weeks for USPS to return the package to you for re-sending via UPS.
19:31 katsmeow-afk i am so peeved at the world today
19:46 Tom_itx the whole nation is laughing at how the South responded to the snow sprinkling
19:53 katsmeow-afk yep, disgusting
19:54 katsmeow-afk national weather service gave 2 days warning for snow and ice, and 2 hr warning for major sleet/snow event, and still no one did a damned thing to prep for it
19:54 katsmeow-afk cept me, and i dunno anyone else
20:48 rue_house did peopl;e try to drive 80mph on snow?
20:53 katsmeow-afk i dunno, but for the most part they managed to average zero mph
20:54 katsmeow-afk news was saying I-20 was still closed today at Leeds, and to consider it blocked thru tomorrow
20:55 rue_house I got the `N5408, bey they are larger than the 1n4007
20:56 katsmeow-afk more amps
20:57 m_itx thinks rue_house should move to bama and teach em all how to d
21:03 katsmeow-afk blast from the past : http://designerthinking.com/images/C64-Vic20/IMG_3409m.jpg
21:53 katsmeow-afk blast from the past , VIC20 style : http://designerthinking.com/images/C64-Vic20/IMG_3410m.jpg
22:27 katsmeow-afk some day i will just give up on irc, because no one is talking on it
22:42 rue_house I'm listening, shoudl I listen louder?
22:42 rue_house how did you do vga on a vic20?
22:48 tsmeow-afk is sn
22:48 katsmeow-afk fwiw, a C64 cannot do vga either
22:49 katsmeow-afk http://www.ebay.com/itm/270993690088 <<== but can you believe USPS says it will not fit in my oversized mailbox, so they won't deliver it?
22:52 katsmeow-afk what the heck is it with the chinese sellers all away till 2nd week in Feb ?
22:58 rue_house holidays
22:58 rue_house time to plant rops at home
22:58 rue_house ^c
22:58 katsmeow-afk but it's winter in Feb
22:59 rue_house so, how? does it have internal ttl RGB lines?
23:01 katsmeow-afk it's got digital rgb and luma ttl feeding the modulator, and that feeds the RF channel 3 or 4 modulator
23:02 rue_house !!
23:02 katsmeow-afk but i told you how i did it, and it doesn't take ttl anything to do
23:02 rue_house huh
23:03 katsmeow-afk the C64 is set up to do 40 column , but with software can display 80 column, with different video chip can do up to 192 column text
23:04 katsmeow-afk i did 80 column text on my C64 ~1984, did get past that on a wintel box till over 10 years later
23:04 rue_house mmm
23:05 katsmeow-afk the only fast-enough display i could get for the C64 and over 80 column was too small to use, it was a rackmount tri display for tv signal monitoring
23:05 katsmeow-afk anything bigegr was too slow back then to do 128 character
23:05 katsmeow-afk at least that i could get my paws on
23:05 katsmeow-afk but the C64 would do it
23:07 katsmeow-afk also had the C64 as master on a IEEE-488 / HPIB buss controlling test equipment and doing test result printouts
23:08 rue_house I wonder what the sync conversion would be to vga directly
23:08 katsmeow-afk for 60hz, it's pretty close
23:08 rue_house I wonder if they merge the sync in or out of the video chip
23:09 katsmeow-afk what chip?
23:09 rue_house the one in the vic20
23:09 rue_house the vid chip prolly outputs hsync vsync, R, G, B
23:09 rue_house and I
23:09 rue_house I suppose..
23:10 rue_house and then its assembled with analog circuits
23:11 katsmeow-afk no, looking at the schematic now, the 6560 chip puts out the entire ntsc signal on one pin
23:11 katsmeow-afk it brings in the complete video in digital tho
23:14 katsmeow-afk the 6567 in the C64 has two pins: chroma and luma+sync , merged outside the chip,, incoming data to display is digital
23:14 rue_house hahah its svideo!
23:15 katsmeow-afk it did a lot of new stuff way back when
23:16 katsmeow-afk the video chip in the VIC handles the light pen and the joystick
23:16 rue_house oo it used static ram
23:16 katsmeow-afk the audio chip in the VIC handles the joystick , there is no dedicated light pen input
23:16 katsmeow-afk yeas
23:16 rue_house is VI 6?
23:17 katsmeow-afk the C64 used dram because it was cheaper, but can use sram too
23:17 rue_house http://www.azog.org/wp-content/uploads/2011/12/vic-20-schematic.jpg
23:17 rue_house 2114 = static
23:17 katsmeow-afk no, the "vi" in "vic20" ,,, vic = video interface chip/computer
23:17 katsmeow-afk yeas, the VIC20 uses 2114
23:18 rue_house ah
23:18 katsmeow-afk the C64 uses 64kx1 drams
23:18 katsmeow-afk i has both oem schematics, and computers sitting here on http://designerthinking.com/images/C64-Vic20/IMG_3200m.jpg
23:19 katsmeow-afk i have interfaced the hell outa C64 in the past
23:20 katsmeow-afk altho the vic was easier, i needed theramspace and couldn't get decent cheap ram to upgrade the vic back then
23:21 rue_house ... overclocking didn't exist in those days...
23:21 katsmeow-afk now, i have like reels of static ram, there's ~600 of 15ns/20ns statics in the cable boxes alone
23:21 katsmeow-afk yea it did, some peple ran the 6502 at 1.5Mhz
23:21 rue_house http://www.sleepingelephant.com/ipw-web/bulletin/bb/viewtopic.php?t=3721
23:21 rue_house I wonder where it starts to fail
23:22 katsmeow-afk there was a 2mhz and a 4mhz version, and there'a a 14mhz that people have overclocked to 20 now
23:22 katsmeow-afk they say there's a 100Mhz fpga version, but it's proprietary and cannot be released
23:23 rue_house is cobal like lisp or assembly?
23:24 rue_house I was getting conflicting results on my searches
23:25 katsmeow-afk neither
23:26 rue_house can you just up the ram on it?
23:26 katsmeow-afk the problem with speeding up the C64 has always been the 82S100, the PLA, what they had before FPGA were invented as a term, the 82S100 was slow and they quit making them 30 yrs ago
23:26 katsmeow-afk i can up the ram on either of them, yeas
23:27 rue_house do they actually count it or just assume?
23:27 katsmeow-afk it's cunted/tested on bootup
23:28 katsmeow-afk the vic takes a while booting, a slow test, the C64 boots lots faster, but does count
23:28 rue_house wonder how much of the 640k you can fill
23:28 rue_house er 64
23:28 katsmeow-afk "fil" ?
23:28 katsmeow-afk i have used all 64k before
23:28 katsmeow-afk plus the two 8k roms
23:28 rue_house merged io space
23:29 rue_house I wonder if any of my appleIIe disks still work
23:29 katsmeow-afk there's two 2364 roms and a 2332 in the C64
23:29 rue_house so 92k is gone
23:30 katsmeow-afk huh?
23:31 katsmeow-afk it's got only 16bit address speace anyhow
23:31 rue_house yea
23:31 katsmeow-afk 16 bits = 65526 bytes
23:31 rue_house I meant bits
23:31 katsmeow-afk so yeas, of the 32k bytes available on boot, i have used all 92k of them
23:32 rue_house http://i53.photobucket.com/albums/g54/dreddnott/vintage/c64joseph.jpg
23:32 katsmeow-afk you canpage the roms in/out with software
23:32 katsmeow-afk there's a megabyte+ plugin made for the vic and C64
23:32 katsmeow-afk no reason you couldn't add gigabytes
23:33 katsmeow-afk i do not see the images on that url
23:35 rue_house http://media2.apnonline.com.au/img/media/images/2013/02/14/9-1710176-rok140213ccomputer1.jpg
23:36 katsmeow-afk ddaaaaaaammmmm
23:38 katsmeow-afk sadly, when people like me (who were hacking when those puters came out in the late 70's and early 80's) get too old to care about them anymore, that collection will be worthless
23:38 rue_house dont tell my attic, it'll get upset at me
23:39 katsmeow-afk someone made a feeble attempt to "upgrade" the C64, but what they actually did was emulate on on a mini-itx in an oversized keybd
23:41 rue_house have you ever installed dos 6.22 on a new 1+Ghz machine with 512+M of ram?
23:41 katsmeow-afk i wanna upgrade the VIC20 by transplanting to a faster much smaller mobo, adding a 2nd 65C02S at 15Mhz, and not limiting the ram, making it dual port ram, and adding hardware like a math coprocessor, otehr direct-to-ram functionalities, etc
23:41 katsmeow-afk no, installed dos3 on a 12Mhz machine, and dos5 on a 100Mhz machine
23:42 rue_house its FAST
23:42 katsmeow-afk dos6.2 on a 133Mhz machine
23:42 rue_house it fits into the L1 cache of the processor
23:42 tsmeow-afk
23:42 rue_house and its not multitasking, so nothing bumps it out
23:42 rue_house FAST
23:42 katsmeow-afk but you have no drivers to access much
23:42 rue_house no
23:43 katsmeow-afk dos was never made for big hdds, big ram, or bloody fast bridges to pci/sata/usb
23:43 rue_house its amusing to see the rompt almost immediatly after it finishes detecting the drive tho
23:44 katsmeow-afk one of the things i never saw on a dos machine was programming the floppy to send a file to the printer, and get it printed , while the computer did other things
23:45 katsmeow-afk you can do that on a C64
23:45 katsmeow-afk you could even make your own custom chars on a commodore dot matrix printer, way back 1984
23:46 katsmeow-afk i made software that could do left and right priter justification by changing the font and word spacing as needed
23:47 katsmeow-afk it defaulted to adding a pixel here or their to widen some chars to fill out a line, instead of just spacing the words way out
23:49 katsmeow-afk i also wanna add 48bit lba hdd addressing to the VIC, and teach it to use a modern keybd instead of that huge box the keybd is on now
23:50 katsmeow-afk the poor things just needs the same upgrades otehr puters have gotten over the last 30 years
23:51 katsmeow-afk i'd then luv to move all my code from the C64 to it, i don't think it's entirely possible to upgrade the c64 as much, the 82S100 made for some whacky memory and i/o timings
23:52 katsmeow-afk might use a ram for it, but i dunno
23:52 katsmeow-afk it's got 16bits in and 8 bits out, and they used them *all*
23:53 katsmeow-afk they don't make the audio and video chips anymore, so why make decoded lines for them, when i wanna output vga anyhow?
23:54 katsmeow-afk plus i'll be using static rams anywhere they touch the cpu, altho i can shovel in a lot of drams and sdrams around them
