| 5300c revival | |
| Posted by: MacUp72 on 2025-02-19 23:37:28 Yesterday I got another 5300c, this machine already was on ebay one time, as I could recall it's photos. was well packaged, sold as defect..came in a nice laptop bag full of goodies like an Apple HDI-30 cable, an PCMCIA Ethernet card with dongle, a modem card, all their complete discs and documentaries. The bottom sticker says it is an AA model, but I expected the battery dead or worse because..well 5300.. I wasn't dissapointed. lol. nice blue gunk.. yummy..so the first thing was to get the stuck battery out and do a quick cleaning job..    | |

| Posted by: MacUp72 on 2025-02-19 23:54:49 after some more scratching and cleaning reassemble time and first test boot..   has 8.1 on it and MS Office but wait..maxed out 64 MB RAM, a surprise.. at least something to speed up the cacheless 1995 wonder a bit.   I put in a 64GB SD card, copied 8.6 on the first partition and after that a copy of 7.6.1 on the second one, via SCSI from the 540c. 7.6.1 boots quicker of course.  | |
| Posted by: MacUp72 on 2025-02-19 23:57:52 I'll try to to speed up the PPC chip up to 117 Mhz via 38 Mhz crystal or resistor re-arranging. from here ( https://alksoft.com/5300_overclock.html)   the way via the resistors is free( no parts ordering) but..they are TINY..I mean really tiny. and finding a matching 38 Mhz four pin quarz is another thing.   | |

Posted by: MacUp72 on 2025-02-20 01:40:50How is the screen quality? it looks ok, could use a recap of course but it still is bright and clear | |
| Posted by: Hopfenholz on 2025-02-20 02:02:32 Is it me, or is your 540c black rather than "powerbook grey". Looks really cool | |
| Posted by: MacUp72 on 2025-02-20 02:14:57 I think the later revisions of the 5300 had darker colored plastics than the earlier ones? | |
| Posted by: MacUp72 on 2025-02-20 23:41:01 try to identify the original quarz, I'm not sure what the specs are, 3V or 5V.. it seems to be a vintage Epson part? but the small label on it is also on Seiko crystals ( of course the package size and footprint are different) original quarz  Epson  Seiko  | |

| Posted by: Hopfenholz on 2025-02-22 11:44:40 Oh yes I remember that project now. Super cool | |
