yes, it's a Performa 475. i like the slim form factor.

Tube🌱Time

taking it apart is easy, just pull those two plastic tabs...

DELETED

@tubetime that explains why you bought it. I spy a iie card.

Tube🌱Time

hmm, there's a card in the PDS slot.

Tube🌱Time

anyway, let's try and get this machine running. i have a funny feeling the video isn't going to work right...

Tube🌱Time

sure enough, the machine chimes, but the video is blank. but i think i know what the problem is.

Tube🌱Time

sure enough, there's no PRAM battery. these machines need that battery or you won't get video!

Tube🌱Time

but where am i going to get a PRAM battery at this hour?

Tube🌱Time

all i have is this 9V battery. 🤔

Tube🌱Time replied to Tube🌱Time

and we have working video! now for the most important question of the day: what version of Mac OS should i put on it?

DELETED replied to Tube🌱Time

@tubetime system 7.5

Always worked for me

Tube🌱Time replied to Tube🌱Time

i'm going to create a SCSI disk image for my SCSI2SD using BasiliskII and the instructions at savagetaylor.com/2019/12/19/ho

Jim Murphy replied to Tube🌱Time

@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.

Tube🌱Time replied to Tube🌱Time

before i can use the Apple IIe card, looks like i'll need to recap it. 😬

Calyo Delphi replied to Tube🌱Time

@tubetime Nah that's just some unmelted solder paste~ ;p

Jeff Haluska replied to Tube🌱Time

@tubetime I like to think you have a stock room full of capacitors.

Sergio Aguayo replied to Tube🌱Time

@tubetime It wouldn't be fun without recapping 😆

Empathic Qubit replied to Tube🌱Time

@tubetime I recapped my SNES a few months ago to protect it. Unfortunately I think it has some problems with one of the ICs. Graphics are all weird. Also replaced the vreg even though the output from that looked fine.

Tube🌱Time replied to Tube🌱Time

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

Raj Patel replied to Tube🌱Time

@tubetime Such a comforting boot screen. Diagnosing Extension conflicts not so much.

Tube🌱Time replied to Tube🌱Time

I mean it's a large volume but should it really take an hour to mount?

solient replied to Tube🌱Time

@tubetime wow I forgot all the partition options the Classic era disk formatting tools had.

Tube🌱Time replied to Tube🌱Time

trying something else. unfortunately this didn't seem to work, I suspect the HFS partition needs to come before the ProDOS partitions.

Piotr Esden-Tempski replied to Tube🌱Time

@tubetime fuzzy feet... not so nice on caps 😬 🦶 💇

davekeogh replied to Tube🌱Time

@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.

AJ from Sweden replied to Tube🌱Time

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

Fritz Adalis replied to Tube🌱Time

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

Raker de W4WWW replied to Tube🌱Time

@tubetime TIL modern 9v batteries use 3x 1/2 AA 3v cells and not 6x AAAA 1.5v cells anymore!

Tube🌱Time replied to Raker de W4WWW

@w4www_raker only the energizer lithium ones, the others use the weird thin stacked cells thing

Justin Skists replied to Tube🌱Time

@tubetime
Huh! TIL that batteries are made from smaller batteries!

Jeff Haluska

@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 tindie.com/products/siliconins

Axel Hartmann

@tubetime someone heard you like apple, so they put an apple in your apple

Tube🌱Time

@nushi they didn't have RAM in the Edo period.

Julian N

@tubetime I have limited knowledge of Apple machines of that period.

jeffluszcz

@tubetime back in my Mac shareware days I had made an app that would warn people if their pram battery had died. Simply just by checking the date and warning if it was back to the default but people in computer lab situations found it useful at least!

J. Paul Reed

@tubetime So many junior high school memories with this bad boy...

Reticent Turnip

@tubetime Is that one basically a Quadra 605? Like...65C040? (It's been a while!)

Eric Vitiello

@tubetime @bitsavers that was such a good form factor. I am partial to pizza boxes though

Lee Hord

@tubetime I used one of these in high school, absolutely loved it. Started to learn my craft on that machine. I wouldn’t be where I am today without it.

Mark Boszko

@tubetime oh man, I used to have one of those pizza box performas. Good times.

David Nelson

@tubetime Love it. The LC475 was the first computer my family ever had at home.

@tubetime this thread is making me wish I didn’t get rid of that LC III I picked up years ago and decided I had no sensible reason to hang into. Sometimes it’s ok to not be sensible.
