You can also use QuickDraw during boot. You may not be able to draw text, but you can draw lines or whatever to mark progress thru your code. You don't have MacsBug in ROM, but there's MicroBug. It has a stub for a serial port debugger. MicroBug uses some of the Managers, so it may not be...

Thanks. I should probably learn to read.... 

No, because the original Mac 128K, 512K, and 512Ke don't have a name printed on front. Early revisions of Frogdesign's ImageWriter II also don't have any name printed on them.

Yeah, you will need to take the drive apart and take a look at the eject mechanism. There is a limit switch that toggles the eject motor. Here's a good starting point: Fixing 800K Sony disk drive

My new technique for these 400K drives is that I remove the 4 screws on the bottom that hold the cassette mechanism. Then I dip it in a pot of boiling water for about 6 to 8 seconds. That gets all that gunk loosened up and outta there real quick. I will document this technique some time. It...

They've been on Mac GUI Vault for a few years: Twiggy Mac prototype ROM I also did some write-ups back in 2014, investigating the file format and ROM: Twiggy Mac ROM disassembly Report on Twiggy Mac disks It isn't necessary to have the adapter. You can merge the contents into a Hi and Lo ROM...

I tracked down the date and some more information about this model based on the written ROM 2.45 label. Persons interested in knowing more about what I uncovered are welcome to email me. You'll find my address in my sigature below (when you are logged in).

Yes, a null modem cable is all you need.

This is what I use: goSerial. Use its Logging option and you can get the raw binary byte stream in a file.

Last week I began porting Internet code from Marina and today my TCP/IP stack is now able to reply to ICMP echo request (pings). Progress log is on my web site and I'll be making all updates there.

I have not verified this information: An old Usenet post from 1991 said that PRAM only stores the SCSI ID #. Partitions are scanned in alphabetical order, so rename the partition that you want to boot from, to come first.

Portable.

Depends on the workload of course. The 030 has a full 32-bit data bus so it can put an entire long-word on the bus at once, whereas the original 68K only has 16-bit data bus. The 030 has instruction caching too.

I already distributed PPP beta 1 to several beta testers who inquired by email. Everyone is welcome to beta test. Just send me an email. You'll find my address below in my signature. The purpose of this PPP beta test is to check that my PPP code will establish a PPP connection using LCP and...

I looked over your code and didn't see anything. I thought maybe you weren't correctly returning the stream identifier, but it looks like you are. In the mean time, I found a UDP sample on an Apple Developer CD-ROM, and I have attached it here.

Attention beta testers: Please send me an email (address below in signature) if you would like to receive a beta test copy of the PPP code. The PPP code should work on any Mac with serial ports, running System 1.0 through Mac OS 9.2.2. Great progress again since last time. It turns out that...

It felt good to get to bed, actually. ;-) It was a late night that night when I finally got the first link-up. I lost a couple days last weekend because I put in some debugging code to show the Debug Window and then print hex dumps + status messages like what you see in the screenshot. In the...

Thanks everyone. I know that's not a terribly exciting screenshot by itself, but the fact of the matter is that my PPP will negotiate a connection with some other PPP's I've tried it with, and also itself. I just ran it on a Power Mac G3 running OS 9.2.2, connected to itself on a Mac 512K and it...

Good news guys, :-) It's not vaporware! I fully expect to have a beta to distribute by this weekend.

No, I've never developed for MacTCP, but I have experience programming the Mac, so I will take a look at your code as soon as I can.
