The Neptune application, part of the Sabina TCP project, is now released in its first beta version. It works to download a web page on a Mac 512K, but I don't have a 128K to test it with. However, the application is intended to work with a Mac 128K too. Anyone who has a Mac 128K and can...

With the TeleDisk application you can transfer entire disk images, as well as individual files, from your classic Mac to a newer computer using an RS-232 serial connection. TeleDisk can also transfer the data from a Macintosh Hard Disk 20. The disk images received from TeleDisk are immediately...

This is a scientific instrumentation package for Macintosh.

A few years ago I wrote a TCP/IP stack called Marina for Apple II. I've spent the past two days looking into how to get TCP/IP on the original Mac 128K and 512K in a way that makes it accessible the greatest number of people, but also affords opportunities for application development: telnet...

Post here if your Mac thought it was 1920 instead of 2020. :-P My Mac 512K with System 2.0/Finder 4.1 recognizes that it's 2020, but my SE/30 with 7.5.3 thinks it's 1920.

I have a Mac SE/30 which when I received it showed this on screen (full size image): (link above for full-size picture). There was no sound. I replaced all capacitors on the motherboard, and now I get a slow death chimes immediately on power-up, with no other obvious change. I washed the...

I'm learning assembly language on Mac 512K. I already know 6502 assembly language for Apple II. I'm working my way through Dan Weston's book, and already I have a couple ideas in mind for what I'd like to write. I think first I'd like to try writing a disk transfer utility that will read a 400K...

Does anyone have a list or database of compact Macintosh PDS cards? I'm specifically interested in cards for the SE/30.

I'm looking for some software from 1985-1986 that used additional RAM in the Mac 512K as a disk cache: Turbocharger by Nevins Microsystems, and PowerDisk. I have the manual for Turbocharger, but no software. :-(

Last night I had the hair-raising experience of shredding/scratching the outer tracks off a couple of 3.5" floppies to the point where all the magnetic media was GONE from the disk and I could see through it clearly. I've seen countless scratched disks before, but never any this bad! Needless...

I have some source code that is written for these two C compilers. Anyone have any more information on them or a source? These were among the first C compilers for Macintosh and were out around 1984-85.

Anyone have documentation for the Apple HD 20 diagnostic program, HD Diag?

For people living beyond the central Illinois area... If one person is interested in obtaining this, or if a group of people are interested in pooling the money for this, I live close enough to Decatur that I could probably arrange to pick up this equipment and distribute it via parcel post...

After researching, I'm still not clear on this. Let's say I've got a machine that's been downgraded from a 128K to a 64K ROM, but it still has the stock 800KB DS drive intact. Will this drive function like a 400K MFS drive?

While looking for information on the Lisa Workshop in Mac GUI Vault, I stumbled across this really neat thing from late 1985: a telnet and tftp ported and/or written by Tim Maroney. It's a TCP/IP implementation that runs on AppleBus. There's IP, UDP, ICMP, and TCP, in addition to two...

  Bring a piece of the famous Twiggy Mac prototype from 1983 home with you. Using technology developed for Mac GUI Vault, I have extracted some resources from the Twiggy System file and formatted them for use with production Macintosh systems. Here, please find the fonts and desk accessories...

Way back in 2009 I got a whole stock of super-early Macintosh disks from that exciting time period of 1984 to 1987 or so. One of the disks was labeled MacDeveloper and it has the first two issues of an electronic magazine for developers. The files were in MacWrite, but through a chain of...

What is this file? That's a good question when it comes to these Apple II files which often have pretty cryptic names, such as "Mmgrdosinst." Earlier this month, file catalogs were added to show the contents of ShrinkIt archives and disk images, but that only helps a little. Having a screenshot...

Anyone here have a PB 100 battery that still holds a charge? I just want to know if there are any still functional after two decades. Also, if you do have a PB 100 battery that does not charge please post here saying so!

Lincoln, IL - Jun. 18, 2012 - Author David Finnigan has written and published a paperback book covering the Apple II computer. Before the Macintosh and iPod, Apple Computer became famous for its easy-to-use personal computer. The New Apple II User's Guide covers everything from setup to...
