  1. In a different thread (over in software), @Dog Cow mentioned that there are magic numbers which can be used to distinguish which version of the stuffit algorithm was used to compress a file. Does anyone have more information on this? I would like to build a utility that can sort *.sit files, or perhaps improve the unix 'file' command to report a bit more than just "StuffIt Archive" when it sees "SIT!". I believe I can compress the same file with different versions and reverse engineer it, but figured I'd ask in case someone had this info somewhere. Thanks, Nathan

    Ordering capacitors

    Thaks for the reply. It's looking like I'll just have to open up my macs and do an inventory. Especially with the SMD caps. I want to make sure the pin spacing is correct, and that everything fits. For example, with the powerbook display caps, people list values but no dimensions, and it looks to me like the size would be very important since they have to fit into the holes in the bezel. One more question... What about hours? I see on Mouser a lot of SMD electrolytic caps are rated at 1000 hours. That seems pretty short. I must be misunderstanding what that value means. Can anyone clear that up for me; what does that rating mean? Obviously they can work for more than 4 days. Thanks.

    Ordering capacitors

    I want to order caps for several of my Macs. I've managed to find part lists for several of them, but the physical dimensions are almost never given. How do people order caps (SMD or THT) without this information?
  4. I just acquired a 165 and 145B, which inspired me to pull my other 165 out of storage. Does anyone have a checklist of things that need to be done to these things to keep them happy? I've pulled the power batteries out of them. I've read about pram batteries... do these need to be replaced, or can I just remove them? And then, what about recapping, is it possible/necessary with these powerbooks? I've noticed that all three PBs have vertical/horizontal artifacts on their screens. Is this likely due to pram issues, or something else? Thanks!

    Improving a PowerBook Duo keyboard

    I don't have a duo. Do these instructions make sense to anyone that does?

    Magnetic port door upgrade

    This turned out great. When you said "iron" I assumed you meant soldering iron!
  8. Just a quick update... I've managed to get the sheep_net module installed; it involved creating a signed key to be able to install the module. But, I don't see an option for slirp in Basilisk. Using my linux box's wifi device, I can't get MacTCP configured correctly and I can't tell if it's because I'm behind a captive portal or not. Here is the output of ifconfig on my linux box... wlp63s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 172.20.7.10 netmask 255.255.240.0 broadcast 172.20.15.255 inet6 fe80::bc3f:7369:c2fa:767c prefixlen 64 scopeid 0x20<link> ether 00:e1:8c:74:a1:49 txqueuelen 1000 (Ethernet) RX packets 22690 bytes 12909244 (12.9 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 12846 bytes 2082221 (2.0 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 If anyone can help me figure out what MacTCP settings I should have, it'd be much appreciated.
  9. I developed a few TCP apps a few (~10) years ago. One was an MPD client and the other was a twitter client. I used Think Pascal and developed natively on old macs. I have recently discovered Retro68 and some of the work/repos that @ants has posted and been inspired to goof around a bit. I'm developing on linux. I have some questions about the best ways to get started and was hoping to start a thread dialogue since after a few days of googling, I have some questions. (1) It's my understanding that Basilisk II will allow me to emulate a mac with ethernet TCP and that minivmac will not. Is that right? (2) I've got Retro68 compiled with Universal interfaces, and was able to compile @ants MacHTTP code. The test program runs in Basilisk, but the networking isn't working. When I start Basilisk, it sees my wifi device in the setup/preferences window (which I select) but while booting it complains... WARNING: Cannot open /dev/sheep_net (No such file or directory). Ethernet will not be available ... so I need to figure out why that is. (3) The Basilisk II that I'm running is installed from the Ubuntu distro, and says that it's version "1.0". I tried building Basilisk II from source, but the config script didn't complained that X11 isn't installed, and I haven't gone back to troubleshoot that yet. I realize this isn't enough info for anyone to diagnose any problems. But advice/opinions would be helpful. Especially if I'm heading down the wrong path. @ants, if you read this... do you develop on linux and use Basilisk II to emu your TCP apps? Thanks, Nathan

    RetroChallenge

    urbancamo, I've always been partial to the winter-warmup myself, sad to see it go. My biggest issue is that with everyone moving from blogs to twitter, the experience suffered for me. So what kinds of things do you need from people? You've asked for help running the October challenge but it's not clear to me what that entails. I'm willing to donate some time.
  11. Whew, thanks shred for the details. Looking forward to getting it set right.

    Good work. Must feel nice to use it.

    Possible? Mount FD through Parlallel Port?

    I was afraid the speed might be an issue.
  14. The idea was that I could write a program to run on my box that takes a mac disk image, and serves it to a real mac via the parallel port through the mac's floppy port. This would be useful for booting macs with bad drives, or macs with owners with no way to write a system disk. Perhaps one could even create a bootable iso that boots a mac... Anyway... I started looking for infomation on the floppy port, and have found little. The IWM seems fairly undocumented. Looking at mini vMac which emulates hardware, I found the quote "Mini vMac emulates the hardware (with the exception of the floppy drive)." which of course begs the question "why?" I figured someone here might have enough sense to know how likey such a project is to be succesful (ignoring the human element of motivation please). Any thoughts or resources out there to help? Opinions?
