LisaList2

Just posted what I hope will be a good video for Marchintosh.


Full how-to on network LAN / WAN gaming on vintage Apple Macintosh and Apple LISA for RoboSport.

How to set up a network for the host (primary) or secondary, and the basics of gameplay, including a complete game.

Get ready for Marchintosh!

In the late '80s Dafax was selling a made-to-order COPS battery backup for the 2/10, but I never saw one. It used NiCd like the ones that leak in the 2/5.

IIRC, the 10 pin header on the 2/10 I/O Board has the +5 Standby voltage, but no ground, so there isn't a really trivial way to connect it.

As long as the Lisa is connected to AC power, the time should be retained, so if using a power bar to eg. turn off peripherals, perhaps you can power the Lisa separately.

Thanks! I'm hoping that this will help us towards, say, disassembling things like the Workshop shell so they can be hacked on to fix bugs, add features, etc.

Ah, so this is why you wanted to figure out the packing algorithm!

Nice work; I bet this will prove to be a really useful tool!

I think this particular copy is just corrupted. All of his disk images are ones that I sent him, and I know that one of my LOS 3.0 images has a bad copy of LisaMandelbrotPort on it. So I don't think anything's wrong with either his Lisa or the program!

A little while ago I published a tool I wrote for listing and extracting files from Lisa filesystems on DiskCopy 4.2 disk images, lisafs: https://github.com/eschaton/lisafs

And just now, I published a tool for dumping the contents of Lisa object files, which can hopefully grow into a more comprehensive RE tool, lisaobj: https://github.com/eschaton/lisaobj

Both are ANSI C99, both are under the MIT license, and (since we need to specify nowadays) I didn't use an LLM in the process of creating either, just the documentation on Bitsavers and the Lisa OS source code.

Part 9, the final installment, is live.
