Now I gotta hunt down the DSP software specific to the TI chip in the 840av

lol what DSP software (also it�s an AT&T DSP3210, not a TI)

if you find the SDK for it let me know, unlike NeXT it wasn�t a standard part of the developer tools

was there ever a public sdk for it? all I remember it being used for was speech recognition and softmodems and those were both system services

watercooled quad? i think a lot of them suffered that fate. how much of it is left?

can you rotate the heatsink to point at the rear fan holes? hopefully it doesn't hit the gpu. i bet you could get away with not cutting anything if you use USB headers on the board to relocate the I/O since you already got the PCI cards lined up.

mpegdec is pretty amazing, i remember having to convert mp3 files to aiff before i could play them in realtime on my old performa 630 and it taking 15-30 minutes per song

apparently amiga nerds eventually figured out how to do it realtime in 68k assembly with plenty of time left over for other system tasks, and it ported right over to 68k macs

I've installed codewarrior on the Quadra, hopefully there's some documentation on that DSP thing somewhere in the reference books

water cooled dual

leaked and died.

this is just test hardware, he real hardware is coming soon. I�m doing the cut out of convenience but I did cut out the io of the g5 board. it�s a lot more difficult because of how little space there is though

I think there was a private SDK that developers could request so people like Adobe and Avid could theoretically use the DSPs

there won�t be in anything from Apple or Metrowerks

here�s an FAQ someone put together

in the modern era you�d probably just want to assemble for the DSP on a UNIX or whatever, and then reverse engineer how to make Mac OS hand the blob to the DSP to run and transfer data with

unless someone has uploaded an ISO of the ARTA SDK somewhere of course

edit: holy poo poo, the Quadra 660AV & 840AV Developer�s Note actuality goes into a lot of detail

oh well, rip. where is the lack of space, the lip where the I/O panel would have been on ATX?

Wild EEPROM: Jul 29, 2011; oh, my, god. Becky, look at her bitrate.

yup. on atx the io area is the same �level� as the pcie, but on g5 the io is extended so the back is flush but the pcie is still recessed.

most people doing this seem to be buying the laserhive kit but gently caress paying money to replace the back panel with something worse.

a few people mount the motherboard inboard, chop off the last inch of the g5 mobo, and then solder extensions to the original io. no cutting on the exterior needed but :effort:

and it also means you need a pcie extension of some sort.

if you mounted it like you have it, with the PCI slots lining up, that leaves the mobo I/O recessed, right? i would prob do that to avoid pci-e extensions, but make a little io panel out of like 8p8c keystone jacks and those usb cables that plug into your mobo header that are supposed to go in the pci slots. what do you really need, besides ethernet, usb, and graphics? i might even be tempted to just block off the old I/O location and stick all that stuff in pci slots anyway. that way you dont need to chop anything up at all

The main problem with doing it that way is that the g5 only has 4 pci slots on the back.

2 would be taken up by any gpu that's faster than integrated
leaving you with 2: 1 as a usb header, and then 1 free for maybe a wifi card or something.

the stock IO uses jacks that extend out to be flush with the case too, so good luck with the 8p8c keystone jack

Cutting the back isn't the elegant solution, but it's also the easiest way to make something that 1) works with any future hardware, 2) doesn't cost any more money, and 3) doesn't involve major soldering.

Wild EEPROM: Jul 29, 2011; oh, my, god. Becky, look at her bitrate.

the biggest pain in the rear end is the front panel though. the power switch only needs 1 pin because it shares a ground with firewire, because of course.

So your choice is either cut up the original cable and then re-pin it to work with your motherboard, buy a pre-built cable like that for $$$, or buy the laserhive riveted on thing with new io things that looks like absolute poo poo.

(or, what I did, which is just take apart the power switch and solder an extension to that and just gently caress the front usb2, front audio, and front firewire)

# ? Nov 20, 2018 06:52

Raluek: Nov 3, 2006; WUT.

does the stock cable use a normal-ish connector such that you can jam in headers or pins or something, solder wires to those, and make your own little adapter? since you say you have to cut up the cable i assume it's not the normal shaped kind where you can depin the connector and fix it without cutting anything. if it is just the wrong shape, i suppose you can depin it and then get the right size connector body and put the pins in that. make a little jumper wire to provide the extra ground.

not that it matters cause youre p set already looks like

Unduly pleased that in the last few-ish weeks I've managed to steal time (mostly from sleeping) to get a few things done:

(Well, if not done done, at least further along.)

TianoCore/EDK II build environment working; experiments proceeding apace
Managed to track down a version of SimNow from the depths of the Internet and get it installed and (mostly) working
Finally got that cross-(meta-)assembler I was looking for in my hands and working on building new tables for it
Successfully tracked down more than one version of another old (circa mid-to-late) 60s-era macro processor and get more than one implementation of it built and tested with some non-trivial inputs; it now joins the others in the upcoming kumite

Most of those things aren't related to each other (well, except the first two, which are at least mostly in the service of the same project), but then again, they're not entirely distinct either.

(Someday I'll have some screenshots... of VGA text consoles...)

stock front panel header is 2x10 pins iirc and the wiring sort of makes sense from an ease of assembly point of view (1 cable to plug in and the USB, FireWire, power button, and power led are all done)

the main problem is that since I don�t have FireWire on my stuff there�s an additional cable and it�s all a pain in the rear end

still preferable to the late g5, which uses a completely different method

i think i would be tempted to depin the one header and get the plastic bodies to repin into whatever headers you needed, and ziptie up the unneeded firewire ones.

until now i thought only the "late" g5 got water cooling, but it looks like they actually had em for a couple years :ms:

A lot of people do that, yeah, but you Need to hook up firewire to get the power button to work.

I took the easy way out and just said gently caress it to front usb and firewire and power led, and just snipped the cable from the power switch and spliced an extension.
