I've got a project Mac II without the "Macintosh II" label on the front. It looks like some bozo (not me this time) decided it would look better without it and scrubbed the area clean. Anyone been able to restore this type of thing? Is this a job for decals, or is there another option available?

Thanks! I've been slowly digging at it as I get time. Quite annoyingly, licensing is the current problem: the Bluetooth SDK library, btstack, doesn't appear to be compatible with the GPL, so I can't use the example code as a base and even linking to the library may also be a problem. I'm trying...

Those all look good to me. The other thing that might be worth adding is a nod toward enabling atalkd if you do set "appletalk = yes"

Wanted to give a short trip report of my experience installing Netatalk 4. TL;DR: release is working great for me, no problems so far. I installed 4.0.1, compiled from source on Debian stable. Instructions here worked perfectly. After installation I perused the excellent 2.x->4.0 upgrade guide...

That's a neat find, quite clean as mods go. Maybe the previous owner upgraded from a pre-SE compact and was unhappy their machine was making fan noise at all?

I'll have to look, supposedly there are newer versions of the original iMac firmware on the OS install disks. Based on other people's reports I'm kind of suspecting even the newest firmware on the original iMac isn't capable of proper USB booting. For what it's worth the command itself worked...

I think you can configure Kea that way using a variant of the following: Disclaimer: this is untested. I keep my retro systems on a separate VLAN so Kea is handling all address assignment.

For @Snial, did some testing today with USB booting on my Summer 2000 iMac DV+ (450MHz). Open Firmware reports this as "PowerMac2,2 3.0f3 BootROM built on 06/13/00" which seems old compared to similar systems on this list. The computer has a good OS 9 install on it already, but I will be needing...

The library should only modify packets with the "netboot" class attached to them. That's added by the option 221 test in the example config file. All other DHCP/BOOTP traffic should be handled normally by Kea. If you have an existing DCHP server then yes, this setup will interfere with it. You...

One bit of caution, some cheap S-Video cables tie one or more lines together or to the cable shield. If you're hacking a cable together buzz out the lines with a meter before using it.

Really appreciate you putting that together, I'll give it a go on my system and report back. It is interesting that Apple apparently didn't expend much effort trying to simplify USB booting. You would think the explosion of external USB peripherals after the iMac came out would have given them...

Thanks all for the nice comments! 🙂 I'll try that on my iMac DV+. I had a heck of a time fiddling with USB in Open Firmware on the original iMac, everything I tried would just lock up OF. I couldn't tell if it was a 'me' problem, something with my USB devices, a computer-specific problem, or...

I figured out a method to net-boot early New World ROM systems into OS 9 using modern server software. Instructions for how to do it are here: https://github.com/saybur/kea-mboot This is quite useful if you need to bootstrap an old Mac without a functional optical drive, or if you want to run...

Before going down the scope route I'd suggest reviewing the log file, which may give you a better idea of what's happening. They have a general troubleshooting guide as well. Enabling debugging should let you know if the Mac is successfully issuing SCSI commands.

They need to be in pairs: either 2x256K (512K total) or 2x512K (1M total). The battery is not rechargeable. I personally use modern Tadiran 1/2AA replacements from a reputable supplier (at least historically I've never seen one of theirs explode). @ArmorAlley listed some other good options. No...

Awesome! And your plan for development makes complete sense, appreciate the info.

That looks great! Glad I'm not the only one who dislikes blank space on PCBs :LOL: Do you have an idea of what the licensing on the hardware/software will be for this?

You're correct on the 4MB main memory, but the LC 475 uses separate memory (VRAM) for video; it came from the factory with 512K (2x256K) but someone must have swiped the sticks at some point in the computer's history. Like @ArmorAlley said, having more is better. I personally use the default...

Congrats on your new computer! The 475 is a great machine, hope you enjoy it. I haven't done it personally but powering with a DC supply is a reasonable approach. The mAcTX LC can convert an ATX PSU to work with your computer, then you can use a PicoPSU and the DC brick. mAcTX LC is open...

I don't have my spec copies in front of me so this is just from memory, but I think SCSI-2 may have been less specific about the drive strengths of active negation drivers than the later revisions. Is that where the above chart came from? The design does look to correctly run the OR-tied lines...
