Apple Lisa Workshop 3.x C compiler disks

Here's the Lisa Workshop folder off the Legacy CD. From what I can gather the C compiler was part of Workshop, but I can't mount these disks to look. It has a few more disks than the usual 9-disk set that can be found elsewhere online.

Thanx ! yeah i'm having problems mounting and converting those images too, I think it may be something to do with running diskcopy 6x under classic.

Yeah I think you'll need to be running System 6 (or under) with DC 4.2.

yeah? its a ndis (sp) image and apple support site says that ndis is a diskcopy 6.1+ format..

does dc4.2 do ndis write only images?

you mean ndif

DC42 does DC42 images.

ah i think dart may work.

now i got to find dart

The images are DiskCopy (type:rohd, creator:ddsk). The reason you'll need 4.2 is because 6.3 requires System 7.0.1 or higher, which is unable to mount the old 400k (MFS) disks.

If you scroll down to the end of this page there's a link to a project that adds native read-only MFS support to Tiger. Might be worth a try!

so i need a real floppy drive? bugger. my pismo doesnt have one of them.

i could build & upload MFSLives if anyone wants.

what is that? if it will help me or it makes 400kb disk images yes please. ive got a g3 running 10.3.9

Diskcopy 4.2 under vmac/6.0.8 wont recognise them. As apples support pages say, ndi(x) images are created by diskcopy 6.1. iirc thats ppc so i guess i need system 7 on a ppc mac emulator that will do disk images to extract these images to files. phew! what a mouthful. and a contortion!

um... they aren't MFS disks. they are Lisa formatted disks.

i dont want to mount them, but diskcopy 6.1 chokes and comlains it cant go on anylonger when i try to convert _or mount_ them. to a dc4.2 image that lisa em uses. in fact any format i try to convert to it chokes.

Dart doesnt seem to help either.

try ShrinkWrap.

It isn't as picky

Thx! im working on it.

OT: is there a fat fs for osx 10.3.9? the std one only reads while i wanna write.

fat fs? you mean WinBlows's Fat32? that has write capibility. NTFS doesn't. if that's your question, then no clue...

Yeah fat 32/16. everyone says it does, but my system doesn't.

do you have PC Exchange or whatever its called? (Classic MacOS)

its built in to OS X

@macgeek

No. but i did get sheepshaver running, with 7.5.5 and diskopy 6.4,

It seems to convert properly, but lisa em says its not a bootable disk.

hummprugh 8-o

Thx macgeek, but shrinkwrap bombs '10' under sheepshaver, with a real pismo runing panther,running 7.5.5.

Hope this isn't too late. These are read-only compressed DiskCopy images. If you wanted to use these in an emulator like LisaEm you need to convert them to either DC42 format or read/write ndif DiskCopy 6.x format. In Mac OS X up to at least 10.4, you do that with hdiutil from the cli. Use the following command for DC42: "hdiutil convert -format DC42 DiskImageX -o NewDiskImageX.dc42" , without the quotes, where DiskImageX is the name of the disk to converted. The ".dc42" extension is for the benefit of LisaEm which seems to prefer its DC42 images with that tacked on. For read/write Disk Copy 6.x images this command will work: "hdiutil convert -format RdWr DiskImageX -o NewDiskImageX" . You can now use this image with the emulator of your choice. Almost all the disk images on the Apple Legacy CD are like this, so you need to convert them with hdiutil if you're going to use them in an emulator.

If you had a Mac with a stock floppy drive you can use these images straight away to make real floppies. Just open up DiskCopy, navigate to "Make a Floppy..." and follow the directions. If you didn't have access to DD floppies that the Lisa's required you can tape the HD hole opposite the protection tab shut on a HD Floppy and fool the mac into thinking it's a DD floppy. A few caveats though: tape it securely - you don't want it to come undone in your Mac or Lisa; data on such disks is very fleeting - sometimes the error detection/correction routines of the Mac will choke on it, sometimes just the act of reading it will corrupt it. Even something as simple as stacking the floppies together or laying them right next to computer/keyboard/mouse can mess them up. And it won't work with a USB floppy drive attached to a Mac.

Another option for making real floppies is DiskDup+

I've found it works much better than Disk Copy for making Apple II disks... might be better for Lisa too.

Nah its no to late

Thx for ur good help! The conversion seems to work, but the dc4.2 imgscrashed lisaem. Sigh. Might try ndif rw. Iirc lisaem didn't support them.
