  2. I use a PATA PCI card with an 8GB CF card on my 9600. Works a treat. It shows up as a SCSI controller in OF, so it boots natively as if it was just another SCSI bus. Edit: I found this thread in another forum with a load of cards which are OS9 compatible listed: http://macos9lives.com/smforum/index.php?topic=306.0
  3. So I worked on this one the last time I was back. Apparently the drivers for these RTL things can support AppleTalk OR TCP/IP, and don't seem happy with both. You need to have "Use 802.3" unchecked in the control panel and a Manual setup is advised, but DHCP does work. Honestly, I think I'll try to find something with better drivers to use in the future.
  4. Tripping an RCD/GFCI? That would be a short/low resistance between live and earth. If you've got a multimeter you should be able to find which conductor pin is the culprit. The worry, of course, is how this has happened. I'm guessing one of the Y capacitors has failed. I don't have a schematic of the IIci PSU, but here's a generic page showing how X and Y capacitors connect across the power input: http://thejourneymanwizard.com/2015/02/04/capacitor-parameters/ If it only happens when the computer is on, it's possible there's something like this on the power output, too, as that wil
  5. There's a tool which does that for you - "Intelligent Battery Recondition" specifically for the 500 series. It even changes the settings to "Panasonic" or "Sony" mode (based on the serial number)
  6. Yeah I've managed that bit. It's the slirp setup I'm having trouble with - I can use the serial link for shell access and ZModem transfers without issue. I'm wondering if someone has actually managed to set it up properly _and_ written it up, unlike most of the "guides" I can find online... (This is the main "guide" I'm referring to: http://www.keacher.com/1216/how-i-introduced-a-27-year-old-computer-to-the-web/ )
  7. So a while back I was trying to make my old powerbook wireless with an esp8266. Turned out that when it said it did SLIP, it didn't actually do SLIP in the same way. That doesn't really matter anymore. What does matter is that it can become a serial bridge, and I can get a linux shell and zmodem transfers and shell across it, great! However, despite reading various guides to setting slirp up for SLIP or PPP access to the network/internet, I cannot seem to manage to get it to work at all. Has anyone made slirp work over even just a regular serial line from a mac using FreePPP, OT/PP
  8. I know this is a bit of an old thread now... but try hitting the CUDA button, then the power button within a few seconds. That should make it boot. If the next boot needs that trick too, then your home made PRAM battery is no good; check the connections.
  9. So... back at the parents' house over the holiday period and I'm playing about with my old 5500. I try to access the internet, but I'm only getting a 169 address... A few hours later, and various combinations of parts/software I have deduced the following: The 8139 card under both Mac OS 7.6.1 and 9.2.2 (seperate partitions, HFS & HFS+ respectively) can access the local AppleTalk network (and can even print to an AppleTalk printer) but cannot see anything in TCP/IP land. This is with both DHCP and manual setup, with the 802.3 box both ticked and unticked, 'load only when needed
  10. One of them is now good enough to boot it up! I get a "your battery is almost dead" message straight away, though, but it's actually quite good progress!
  11. Got the first two on the charger. Number 3 I don't think I can recover, as it's rattling. I suspect the plates have disintegrated.
  12. I actually have something very similar for my motorbike. Annoyingly it only does 12v batteries. Good thing I have a few of these! Once I've got this one to at least "50%" I'll do a second, then put them in series on it. A lesson I've already learnt: don't put too much water in! I'm not sure the best way to know how much is too much, but when they leak all over your powerbook it's not fun to clean up! :-S
  13. It's been charging for the last 6 hours or so and it's up to 4.9v. That's still way less than even 10% full, which would be 5.75v, but it's actually not bad, considering. I'm hoping another 12 hours or so should do it! See the column for a 6v battery
  14. Just the Portable (which is easier to rebuild as they're huge) and the 100 use SLA. TBH it's not that bad, as even if the recovery is successful I doubt I'll get much capacity; these things only got 2-3 hours new!
  15. Before starting I had 0.1v across this dead battery. So I bought some water, squirted it into the cells (they take a lot!), stuck it on a high-current 5v supply for about 5 minutes and got it to about 2.5v. After this I put the caps back on, taped the cover in place and stuck it in the powerbook... 5 minutes later I'm getting 3.6v, although the battery meter is constantly showing full (although it does that when there's no battery too, not sure what that means exactly...) I'll give it some more time and see how it goes.
  16. I think you misunderstand me. The batteries consist of 3 2v lead acid cells. They're "sealed" in that they don't have obvious screw caps to top them up, but pop the end off and there are three rubber caps which allow venting, but also access to top them up! Have a look here:
  17. Has anyone tried recovering a PB100 battery? There are a number of guides online regarding recovery of SLA bateries like the one the PB100 has... and having a look at the battery, it's pretty easy to pop the top & remove the caps to get to the cells. I realise these batteries are getting pretty damn old now, but it's entirely possible that if they've been dry for 10+ years they've not gotten *that* much worse? I might by some deionised water and try it out!
  18. As long as you have PC Exchange control panel (7.5+) or the File Exchange application (7.1, on the TidBits disk or maybe in 'Apple Extras') then they should work just fine.
  19. Looking at this: http://hackaday.com/2016/08/22/ask-hackaday-calling-all-68k-experts/ I'm wondering if there's just a set of jumpers telling the Mac to look for an FPU or not... But I can't find pictures of the back of a 550c card to check if what look like jumpers between the LSI chip and the connector are indeed jumpers, and whether they should be set differently if they are. The 540c card seems to have all three unpopulated. (R700/701/702, see 00:30: https://youtu.be/82OkgLW_lnY?t=30s ) Can anyone take a scan/photo of a 550c CPU card to confirm/deny this? Thanks! Adam
  20. If you have a Colour Classic II you can run 8.1 with hacks, if you have enough RAM. http://home.earthlink.net/~gamba2/os8_68030.html EDIT: I realise you said not the II!
