09:21 AM rue_mohr: polprog, I didn't see that survey :/
09:36 AM polprog: rue_mohr: it got buried :(
09:36 AM polprog: which sucks
09:36 AM polprog: so, what do you think
09:48 AM polprog: hmm. fishtape
09:48 AM polprog: i learnt something new today
09:59 AM aandrew: https://register.gotowebinar.com/register/4964348188378570768?source=Marcom
09:59 AM aandrew: European FPGA webinar, no restrictions to country and free FOGA board
10:00 AM aandrew: It’s 9AM Germany time, 3AM EDT
04:11 PM polprog: looks interesting
04:12 PM polprog: but i have classes then :<
07:01 PM aandrew: Sign up and get the free dev board anyway
07:02 PM aandrew: It’s a nice little max10 board, I have a couple that I bought
07:03 PM polprog: i think ill do that then
07:06 PM polprog: shame that i cant attend.. wendesdays are busy
07:06 PM polprog: thursday on the other hand..
07:27 PM polprog: i should come back to the 74xx04 amplifier project
07:27 PM polprog: i could probably make it more linear by connecting to ground and vcc via resistors
07:28 PM polprog: 74 series abuse intensifies
07:28 PM Tom_L: :)
07:30 PM polprog: so, like a class a amplifier but a 74 series instead of a transistor
07:30 PM polprog: and i should probably be running them at way more than 5V
07:30 PM polprog: i set 5V because thats what im used to set :V
07:34 PM polprog: the 7406 is open collector, that could work nicely with a resistor too
07:48 PM rue_mohr: heh
09:09 PM rue_mohr: so, I started working out how to wanted the system library to be for the z80 and things got kinda crazy kinda quick
09:37 PM aandrew: heh yeah?
09:39 PM rue_mohr: I must stick to small changes or I'm gonna go into runaway
09:40 PM rue_mohr: right now, the cursor rolls back to the top of the screen after the end
09:40 PM rue_mohr: I'd really like it to scroll the whole thing
09:40 PM rue_mohr: but its 2 control chips
09:41 PM rue_mohr: and I dont store the data, I just send it to the screen
09:41 PM rue_mohr: so, moving text up a line isn't easy
09:42 PM rue_mohr: I could read from one and write to the other
09:42 PM rue_mohr: -
09:42 PM rue_mohr: I'd also like to do xy cursor positioning
09:43 PM rue_mohr: I almost wonder if I should local buffer the whole screen and do a dirty flag/redraw
09:43 PM rue_mohr: I dont know how fast the z80 can push a whole screen
09:43 PM rue_mohr: prolly pretty fast, its only 160 chars
09:44 PM aandrew: rue_mohr: you saw that link for the fpga webinar iwth a free max 10 board?
09:44 PM rue_mohr: yes, not sure what to do
09:44 PM rue_mohr: I suppose the ide wont work on linux eh?
09:46 PM rue_mohr: the windows laptop is becomming quite a paid
09:46 PM rue_mohr: hah
09:46 PM rue_mohr: pain
09:46 PM rue_mohr: almost every time I go to touch it, its got some kinda thing it wants to do
09:47 PM rue_mohr: I'v not watched netflix in quite a while, maybe I should just wipe it
09:47 PM aandrew: max10 uses quartus which is windows and linux
09:47 PM rue_mohr: (install linux)
09:47 PM aandrew: I've only ever used the linux one
09:47 PM rue_mohr: ooo!
09:47 PM rue_mohr: WELL, maybe I should make another burner email and sign up
09:48 PM rue_mohr: oh I cant be there live tho
09:50 PM aandrew: me neither, I won't be up at 3am my time
09:52 PM rue_mohr: whole bunch of effort to set up another burner email
09:54 PM rue_mohr: oh who does my domains again...
09:54 PM rue_mohr: oh right, doteasy
09:56 PM rue_mohr: hmm $156 usd/year..
10:01 PM rue_mohr: "OS - Linux
10:01 PM rue_mohr: Your system cannot install the desktop software, but if you are on Linux or Google Chrome OS then you can join from the most recent 2 versions of Mozilla Firefox or Google Chrome. You can also switch to the mobile apps or a Windows or Mac computer."
10:02 PM rue_mohr: "Browser - Firefox 52
10:02 PM rue_mohr: You can join the webinar but may experience limited features unless you update your browser. "
10:03 PM rue_mohr: "IMPORTANT: To obtain the MAX1000 board required for the labs, please follow this link: https://forms.office.com/Pages/Res..."
10:06 PM rue_mohr: "Thank you for your interest in Intel FPGAs. We will review your request and will contact you shortly. Please be aware that under some circumstances it might be not possible to ship a board to you. "
10:06 PM rue_mohr: carrot
10:08 PM rue_mohr: I mean we will see, I never seem to get to play the reindeer games.
10:33 PM Tom_L: your ff is a tad bit behind
10:33 PM Tom_L: 87
10:43 PM rue_mohr: I like menus and scroll bars
