i generally just use 7.1 as well, 7.1.1 with the 7.1.2 updates. i have 7.0.1, 7.5.5, 7.6.1 and 8.1 system folders too (mostly for testing projects with) but even though i've got one of zigzagjoes booster 2.0 clones in there (which is great btw) i find anything past 7.1.1 a tad to slow for my liking.

actually forget what i posted earlier, i did some digging around and if you open a hfs+ drive on a a non hfs+ aware system say 7.x it shows the 'where have all my files gone' txt file but also there is a hidden system file and empty finder file both marked with the 'invisible' flag. i came...

i just had a look on Mac OS 8.1 and i suspect its probably only the 'Unicode Encodings' File that it needs from the folder im not really to sure what that actual issue is because scsi manager is included in most/all? 040 68k mac roms but they still cant boot hfs+ drives. its jsut something...

im pretty sure the IWM has been or has mostly been reverse engineered. there's definitely super hires pictures of the die floating around. finding someone with enough time and interest is the real issue. the vintage mac community is really quite small in comparison to others like the Amiga or...

i dont think theres anything wrong asking the members of the SWIM dev team but id be surprised after all this time if they'd have much useful to add. as for apple releasing the IP well who knows what they would say. we did get the source code for most of quick draw and was it macPaint or...

i wonder if it would be easier finding someone who can delid a swim chip and take hires scans of the wafer and reverse engineer from there. that seems to be the common approach these days to figuring out vintage chip designs. someone like CuriousMarc might be able to point you in the right...

I might be wrong but I seem to recall part of the issue with booting HFS+ on 68k machines has to do with the scsi manager version in the ROM. I’m not sure how how editing the rom for that would be.

Hard to say for sure, but the Beatles fan in me likes to think it was more intentional rather then just a coincidence

I me mine was recorded in 1970 though to be fair John was gone by them. The End was the last time all 4 were in the studio recording together.

@superjer2000 i probably shouldn't have used the phrase "clear indicator" when i posted above, might have been better if i said it was suggestive that there may be a short. in fact i just went and measured 2 recapped (and working) SE/30 boards i have sitting around and got the following values...

Most things don't fail with a hard short, a partial short is much more common with digital Logic, 150 ohm to ground on the +5v rail and 53 ohm on the +12v rail are both clear indicators there is a partial short to ground likely inside the internal logic of one of the IC's. those reading are well...

those readings seem very low, id expect to see Kohm values. wouldnt hurt to pull all the ram, the ROM and the socketed PAL chips out and see if theres any change to those power rails you measured. maybe youll get lucky... if memory serves correct C9 if on the negative -12v rail. im not sure what...

good practice might be to check for shorts after pulling that blown rom, so +5 to Ground, +12v to Ground and +5 to +12v. personally after i do a full recap i normally just quickly check for power rail shorts before i power on. particularly due to the cap goo often eating away solder mask and...

I don't use any chrome based browsers myself, but i can confirm Firefox also has some mouse pointer issues, moving the the mouse pointer around seems to be 2-3 times slower on the emulation compared to my actual computer. apart from that i was able to run system 6.0.7 fine. i only did some quick...
