Olivetti M24 and ATT 6300
| Preliminary Information | |
|---|---|
| Release Year | 1983 |
| Leak Risk | High |
| Batteries | Yes, RTC known to leak |
| Mounting Technology | Through Hole, Sockets |
| Capacitor Types | Aluminum Electrolytic, Tantalum, Ceramic, |
| Destructive Entry | No |
Created by Olivetti and licensed by AT&T the M24/ 6300 is an 8086 PC clone with some proprietary changes
Known Issues
Battery on Motherboard Leaks
Causes
- RTC battery can leak and cause corrosive damage
Solutions
- Remove battery and clean with baking soda
No Power
Causes
- Pins soldered on the power supply board may be broken loose, especially for heavy parts like transformers or connectors like for the molex power cable.
-
Pins on transformer on second stage of PSU PCB cracked loose
-
Pins on Molex power connector for floppy drives on second stage of PSU PCB cracked loose
Solutions
- In a pinch, reflow the solder to reconnect it. But new solder should be added.
- After reflowing parts could be glued down to help avoid it happening again
