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...

are you using Nuvotech driver? because if you are then that's likely your issue. @saybur can probably say more but we did a lot of testing with that driver on the scuznet and it was alway unreliable, and seeming to cause subtle different stability issues depending the Mac used. that's basically...

even on the SE/30 I have trouble with the bluescsi unless its externally powered. this behaviour does change slightly symptomwise depending on the firmware used. obviously overclocked fw wll draw more power on the bluescsi, however I think he mentioned in the video he tried stock fw. also im not...

absolutely, im sure even with all the resources available today that to be able to patch the system boot process to do all that stuff would require some serious skill. from memory, and im not a coder, ive just read about it but when the system file boots there are a bunch of PTCH resources that...

doesn't mode32 just patch some 24bit rom code that's still left over in the dirty roms, place changed code in memory and change the pointers to look there for the code rather then the rom space address? that's just my assumption really? like the actually implementation is probably much more...

I have no idea if the se/30 rom will work in the IIsi or not, I don't have a iisi myself but there's likely a pin headed jumper you need to swap to change from the built in rom to using the Simms. the romulator is cool and quite hardly depending on the situation. being that I have a 3 se/30's...

I know TMON is meant to support .map and symbol files I dunno if that's of any use as I have no real skill in using these debuggers being a hardware guy myself

oh ok, yeah thinking about it I guess that would work if force32 loads aftefter mode32. I haven't used mode32 in quite a few years and I don't recall any stability or software issues from it myself, im assuming you haven't either. So using mode32 could save him some money rather then buying a...

no need to be sorry, I did just watch his video actually as I got curious. and I agree there's most likely something else going on with his Mac and that accelerator being used together, the scsi booting issues he had would probably have me looking at the scsi controller and related circuitry...

I haven't seen action retros video, its not really the kinda stuff I watch on YouTube. a friend of mine had one of these a few years back for his SE I seem to remember him mentioning there were some issues. like I said last post though im probably wrong, in fact you mentioning about the...

nah its probably not the display being bad. you need a proper degaussing wand to fix this issue.

before you replace the rom socket, have you actually cleaned up both there Rom and ram sockets as well as the rom/ram Simm contacts using ipa? you could have intermittent connections there. also replacing the rom socket might not actually be easy as getting those sockets (64pin SIMM I think??)...
