🧵 1/x

thanks to @billgoats and @paulrickards this LC 475 is going for its first flight in over 20 years.

i rescued this fella last summer from a retired junior high school teacher who himself rescued it from his former mac lab in the mid 1990s. you can even see the old asset tag for Parkland School Division which I will leave on for historical value :) this was workstation #8 in his class

the LC 475 was the “education market” version of the same model of Performa. it has a speedy 68040 which I’ve never used before

for this year’s marchintosh - the first i’ve participated in! - i will be turning the ol gal into a WAN AppleTalk network router, and FirstClass BBS node :D

those poor kids got a LOT more mileage out of this old gal than i would have imagined. the last accessed file date appears to be 2002. 😲

@vga256 System 7.x was the peak of classic MacOS UI design in my opinion. It just had a refined look that I loved. 8 and 9 kinda lost that.

@zorinlynx @vga256 I had that boombox as well!

um. haha.

well, i guess apple never imagined System 7.5.5 would be used past 2019.

The user tries to adjust the system date past 2019 and it keeps rolling over to 1920.

@vga256 A sure sign of the internal use of two-digit years.

I'm afraid this system is not Y2K compliant...

@just_one_bear kinda wild to only store 100 years worth of data when 1 byte for 128 years comes pretty cheap

@vga256 Crafty cruftiness from the early days. Using the byte to keep a pair of BCD values meant the date could be held in 3 bytes and if the machine was adept with BCD (and the 68K has instructions for such packed BCD) it was pretty quick to manipulate in that form. So it was a multi-dimensioned trade-off. Not the best for anything but about the best considering everything. At the time :)

unbelievable. it booted from the original scsi drive!
that horrible spindle whine tells me this has to be a quantum fireball of some kind 😆

and it looks like all the old school files are even intact!

@vga256 Ooh, neat! :D I miss FirstClass, was thinking about it recently actually. I have a Quadra 605 I should get up and running soon, which I think is the same machine as that one.

@sen i miss it too - to this day i've never seen a software package that could do what it did, especially with such a nice gui :D
