Autopsy Apple Macintosh LC 580

I got a few decommissioned macs from the old printing house, I want to tell about one of them.
Monoblock Apple Macintosh LC 580
This model was produced by Apple from 95 to 96, I got a model without a CD-ROM, but with a 800 MB hard drive and 32 MB RAM, a processor from Motorola 33 MHz. Not the most powerful of course, a representative of his time, but in Russia it was very difficult to get such good, it seems to me and expensive. I can only guess what money he bought for then, given that in the USA it cost $ 1300-1500.



Let's see what is inside of him.

There are connectors on the back side (left to right bottom row):
To connect a keyboard and mouse, to connect a printer; the printer, by the way, was bundled (LaserWriter 4/600 PS), a modem, scsi, a microphone and headphone jack (the microphone in it was built-in, it’s not clear why it was needed at that time - well, it’s obviously not possible to chat on Skype ), and a network card for twisted pair.
To get to the insides, you need to unscrew the back cover, so it still held on the latches, but they were already broken off (the plastic became very fragile from time to time, I myself broke a couple of latches while I took it apart).


Having removed the cover, we will get access to the disk: it is located on special rails, it is nothing outstanding. Quantum 800MB IDE, but with an apple logo.

To get to the motherboard, you need to unscrew two more bolts and pull with a force the special handle towards you. First I pulled lightly, thought - I would tear something off, and only then having found the original instructions and reading that it was necessary to do so, I attached a good effort pulled the board out of place.


The board is also located on the slide and is very securely mounted in the case.
Although the computer is all-in-one, it still supports various extensions, the battery for maintaining the time in the computer is especially noteworthy. Although running ahead, I can say in advance that he did not show me the exact time (Mac OS 8 did not expect that it would survive until 2000), 2 slots with SIM memory and a processor without a heatsink. If someone knows what that little red button is for, write how I understand it refers to scsi.

After removing the front panel, you can see a free connector for connecting the drive and slide rails, the drive is also located on the slide.

Having removed the casing, we get access to the remaining entrails.
At the top is a power supply soldered on the same board with the monitor; to cool it, a fan is used that is in the case, that fan receives power very elegantly, and when you disassemble the case, you do not need to disconnect any wires.

It interfaces with the power connectors on the board and receives power from them.

The kinescope power board itself is located on the next slide. Two connectors are connected to the rest of the electronics (on the left there is power, and on the right there is a video signal on the screen).

In general, the whole structure is a sandwich in the middle of which are various storage media (HDD, FDD, CD-ROM). At the top is the power and picture tube control board. Bottom is a motherboard that is shielded from radiation by the power components.

At first, I didn’t immediately figure out how it turns on: it didn’t have an on button on it, like on the other poppies that I got, but then, having connected the keyboard, I managed to turn it on with a special button from the keyboard (upper right key.). An interesting feature: the mouse has a short wire and sticks into the keyboard, and the keyboard is already connected to the computer so that fewer wires hang from the table.


It loads pretty fast.
Unfortunately, on the machine itself there is little software, more precisely, there is only one quark express and system utilities, there is not even a browser, so it was not possible to connect to the Internet. Pay attention to the image on the screen: the corners are rounded. This was important for CRT monitors. The computer is fully operational and even makes sounds from the built-in speakers.

In general, the design, from the point of view of design is very thought out. This is the youngest model of the poppies I got, in the future I’m going to talk about the Power Macintosh 7500, Power Macintosh 9600, and LaserWriter.

PS: I don’t own poppies myself, and poppy wasps are new to me, so if I wrote something wrong, please inform me in PM.
