nice design there, fwiw with a 12v 40W psi that's only about 3.3A, so it's going to be important to check exactly what the se/30 requires on each rail. I don't have a se/30 open in front of me right now but from memory the +5v rail is speed for around 6A and the two 12v rails combined are around...

just re-read the OP and in regards to it taking ages to finishing scanning when you use the open firmware boot picker its because the boot picker also searcher for Netboot devices and will do so regardless if you are connected to a lan or not. my understanding its it its listening for the...

termination needs two be applied on the last device on the bus. so since you have no other devices then you need to use termination

you really shouldn't need to mess around with naming files with LUN ID's as I don't think the Macintosh OS really even know anything about dealing with LUN addresses (someone correct me if I'm wrong here), the LUN feature is really just a hold over form the original Zitto firmware for the sharp...

just install the apple appearance manger sdk for system 7. it'll give you the platinum theme and from memory will let you also set fullscreen desktop images/pictures

fwiw those disk cleaning kits don't always work. usually they are fine but if there's any dirt or anything backed onto the heads then a cleaning kit won't work. usually I use a bit of dish washing detergent on a q-tip followed by some IPA on another q-tip, I've found that manually cleaning the...

here's a compiled hex file of the v4.84 firmware normally I don't like providing compiled firmware but my understanding is the the v4.2 hardware is open source, unlike the 5.x versions. though the firmware source for those also appears to be out on the internet too so in mot sure really what...

the video issues with the DVI output are probably related to the Pixel maxing out at 135mhz. those Mac minis really work best using VGA. as mentioned try holding down shift at boot, and see if you can change the rest rate as well. I've had issues in the past with the monitors control panel...

usually holding C should boot a CD-ROM drive attached to I think if I remember correctly SCSI ID3. however the command I mentioned in my last post will just force the Mac to look for a bootable device on the SCSI ID you specify ( ID 5 in my example). it doesn't matter to the Mac if the device is...

I used to use a tool called LeopardAssist that allowed you to do this using a GUI (works in tiger too), but I might save this script for future use. fwiw the OS X startup control panel appears to check for what version of MacRISC support is listed in open firmware. Enabling these options in...

You need a Jtag programmer that works with Cypress PSoC devices. It’s probably cheapest to buy A psoc evaluation kit that has a programmer built in you can reuse on other psoc devices…. Thing is most are sold out or very expensive. Really unless you already Have all the parts needed then it’s...

if you remove the 3.3v wire from the harness then the 630 board electrically will work, the only difference in the connector pinouts are that single wire. the only thing on not sure about as Its been awhile is just the sense wiring config. I can't remember what the 5500 is setup for video wise...

I can confirm that I while I'm used to seeing c12 at the Botton right of the ROM socket I have actually seen 2 se/30 logics boards with c12 near the battery socket. both used sockets CPU's too fwiw.

a really good resource I've used over the years for classic Mac music production is actually the DAW subform on macos9lives.com there are a huge number of people there who to this day continue to do music production on pre OS X Mac machines so they're probably a huge amount of information you...

I was about to say cubase but you've already mentioned it. there's probably similar DAW software such as eMagic Logic etc but the thing is software instruments specially those used in DAW software will tax the cpu but more importantly they need a decent amount of RAM. there's certainly lots of...

interesting, I actually don't think I've used Anubis before, I mostly use a scuznet for my sd card to scsi solution so I'll have to download a copy and see what performance I get as looking at you linked results it appears that I might get even fast results

not BlueSCSI specific, I was reading an old Macformat magazine that had some benchmarks between a bunch of scsi format utilities and it was a showing that most of the 3rd party utilise drivers weren't as fast as the apple driver.. long story short I did a bunch of tests myself and come to the...

firstly don't use lido, either use the apple scsi hd format utility or perhaps scsi director. I mention this because I did benchmarks with a large number of vintage Mac formatting utilities and I found with my se/30 that the LIDO hd driver along with most others actually performed a lot worse in...

seeing this post reminded me that I had built up one of these v4.2 boards a couple years ago but never flashed the firmware. long story short I dug it out today after compiling and flashing and then updating the board to 4.8.4 I get the same scsi self test fail but it appears to work fine on the...

to be fair you put a huge amount of effort and skill into decoding the hardware and the nuvo protocol so I wouldn't call that stubborn at all. more so its both impressive work and having that protocol documented online may mean someone down the road can figure out the driver issue and possibly...
