Tube🌿Timei got a new Apple! 🧵
anyway, let's try and get this machine running. i have a funny feeling the video isn't going to work right...
sure enough, the machine chimes, but the video is blank. but i think i know what the problem is.
sure enough, there's no PRAM battery. these machines need that battery or you won't get video!
but where am i going to get a PRAM battery at this hour?
and we have working video! now for the most important question of the day: what version of Mac OS should i put on it?
i'm going to create a SCSI disk image for my SCSI2SD using BasiliskII and the instructions at https://www.savagetaylor.com/2019/12/19/how-ive-setup-the-scsi2sd-that-i-use-in-my-lc-475/
I was having trouble because I was putting the *volume* image into the SCSI2SD rather than the *disk* image. turns out partition tables are important lol
trying something else. unfortunately this didn't seem to work, I suspect the HFS partition needs to come before the ProDOS partitions.
well this explains why it was hanging. there's probably some setting on the SCSI2SD that's not exactly right.
turns out this hang was caused by the SCSI2SD firmware, which was uhh shamefully out of date. with the latest version it works and i can partition the drive!
it also turns out that MacOS wants to be the first data partition (i had the two ProDOS partitions first.) but it works now!
Travis Geiselbrecht@tubetime Yeah I've had mixed results with the SCSI2SD and random old hardware. A particularly weird one is suddenly the same one I've had forever stopped working on my Microvax. Used to work, now doesn't, no explanation.
Guess I should logic analyze that one.

Karl Gutwin@tubetime Seeing this is dredging up ancient memories of playing with not-new SCSI gear as a kid… staring at the baroque arrangement of peripherals, utterly confused as to why it wouldn’t just WORK.
Kids these days don’t know they have it so good, what with their “universal serial bus” and all. You don’t even have to worry about device IDs! Or bus termination!

@kgutwin it's still a confusing mess when it comes to USB 3.0/3.1/Gen 1/Gen 2/3.2 Gen 1x2/2x2 and all the weird alternate mode issues.
solient@tubetime wow I forgot all the partition options the Classic era disk formatting tools had.
Peter Redecker@tubetime did it finish or did you stop it?
Taki@predecker @tubetime I remember when my Linux installation automatically did a fsck after 20(?) mountings. That wasn't an issue until I replaced the hard disk with a quite bigger one...

@tubetime Such a comforting boot screen. Diagnosing Extension conflicts not so much.
King Naga Calyo Lucere-Delphi@tubetime Nah that's just some unmelted solder paste~ ;p
Jeff Haluska@tubetime I like to think you have a stock room full of capacitors.
Sergio Aguayo@tubetime It wouldn't be fun without recapping 😆
Piotr Esden-Tempski@tubetime fuzzy feet... not so nice on caps 😬 🦶 💇

Robert Praetorius@tubetime better to discover through corrosion than explosion
Jim Murphy@tubetime As a new hire at Apple I authored the 7.5 installer script. I moved on to doing software engineering on the OS by 7.5.3, but that always gives me a nice feeling to see it still running.
davekeogh@tubetime any recommendations for 68000 emulators? I remember using one must be nearly twenty years ago now, but it had a nice gui with the register contents and possibly a few LEDs. Had to build a 68k dsp in college. Would love to play with some assembly again.

@tubetime oh gee.

@tubetime Never even crossed my mind that this was even a thing… 😮🥳

Weird, all the ones I've taken apart had 6 skinny batteries vertically.

Ken Ryan@FritzAdalis @tubetime That is a lithium 9v battery. Alkaline has a 1.5v cell voltage so needs 6 cells. Lithium is 3v cell voltage, so only needs 3.
@tubetime TIL modern 9v batteries use 3x 1/2 AA 3v cells and not 6x AAAA 1.5v cells anymore!
@w4www_raker only the energizer lithium ones, the others use the weird thin stacked cells thing
Justin Skists@tubetime
Huh! TIL that batteries are made from smaller batteries!

Rob E.@tubetime bodgewire a CR2032 or similiar?
@tubetime Never thought you'd need a battery for video.
Michael Engel@tubetime Thanks for this hint – my LC475 is working again now using the MacBatt PCB which replaces the lithium battery with a CR2032 coin cell https://www.tindie.com/products/siliconinsider/macbatt-cr2032-pram-apple-macintosh-battery/
Axel Hartmann@tubetime someone heard you like apple, so they put an apple in your apple
Ω 🌍 Gus Posey@tubetime That is so hot.
