stepleton Posted August 10, 2020 Report Share Posted August 10, 2020 I hear you! Just trying to keep my own projects from getting stalled at 60% lately. In fact I'd written this comment days ago and hadn't pressed Submit yet. Good luck! Quote Link to post Share on other sites
guibrush Posted January 19 Report Share Posted January 19 Hi, I wanted to try Gemdos on my lisa, but looks like the link to the discs are broken. Is there any other place where I can download them, or did anybody saved them? Thanks in advance Quote Link to post Share on other sites

Try them again and if you can't get it to work, let me know and I'll upload them somewhere else. I'd prefer not to long-term host them myself, is all, the forum is more reliable than my own machines (Also, if you have an X/Profile, I can upload a CF card image for you, which it just occurred to me I never did) Edited January 19 by cheesestraws Quote Link to post Share on other sites
guibrush Posted January 19 Report Share Posted January 19 ha, now it's good. I thinks that I did a mistake somehow with my registration on the forum, sorry for that. I give a try! Thanks Quote Link to post Share on other sites

guibrush Posted January 19 Report Share Posted January 19 I will do. I have a Lisa 2/10 with a Xpfrofile installed. Quote Link to post Share on other sites

Try this, then: this is an image for X/Profile that you can dd onto a 32 meg CF card. It has GEMDOS pre-installed as per the instructions above. Mode=3, Target=0, should Just Work™. Run 'GEMVDI' to start the desktop. GEMDOS.img Quote Link to post Share on other sites
guibrush Posted January 20 Report Share Posted January 20 (edited) Ok, I just tried your image.... And this is fantastic All run fine, "GEMVDI" bring me the desktop, I can launch the "hello world" app and the sketch app. Trying to access the floppy issue a instant reboot. The rest looks promising. Maybe I will try later some Atari apps, who know, with luck some basic apps could run. Thank you verry much for this work, this is awesome. Do I understand right that this setup was used by Atari and Digital people to write the GEM / TOS for the ST? Here some pictures of my setup: https://imgur.com/a/oH68z2D Edited January 20 by guibrush Quote Link to post Share on other sites

I know that First Word roughly runs, and some very early Atari software ought to. If you play, I'd be fascinated to hear what you find out. 3 hours ago, guibrush said: Trying to access the floppy issue a instant reboot There is basically no error handling at all in this version of GEMDOS, and the filesystem handling is... fragile. What discs are you using with this? Transferring files via floppy is a right pain because the physical format of the floppies has to be GCR, but the filesystem has to be FAT12. So you can't just use Atari or PC floppy discs. An anonymous person (who I wish would turn up so I could thank them, I couldn't have got this working without them) built a tool to make floppy images in DiskCopy 4.2 format that you can copy onto floppies with an old mac, or use with something like the Floppy Emu. It's here: http://www.alternative-system.com/en/revive-gemdos-for-lisa/ but note that in order to get different files onto the disc you actually have to edit main.c. Trying to turn this into a more useful file transfer tool is something I wanted to do but failed to. There are some extra utilities available for this version; the compiler suite, for example, and a port of kermit. I haven't put those onto floppies or transferred them to my Lisa, so they're not on the card image I sent you, because dealing with floppies is a massive pain and I'm lazy. They're available in the porting kit anyway - the rest of the kit can be downloaded from Ben Jemmett's website here: http://www.deltasoft.com/downloads-gemworld.htm 3 hours ago, guibrush said: Do I understand right that this setup was used by Atari and Digital people to write the GEM / TOS for the ST? The original Lisa port was part of a porting kit which was provided to companies that wanted to port GEM to their hardware. It consisted of a build of GEMDOS and GEM for Lisa (binaries only), the source code to the hardware-specific bits of GEMDOS for the Lisa, the source code to the screen driver for the Lisa, and the necessary compiler and build system to build GEMDOS from these parts (plus various binary blobs). So essentially, it was a 'port GEM to your 68k hardware, just add a Lisa' kit. I don't know if that kit was exactly what Atari got to start their porting efforts, but it would have been pretty close to it. Unfortunately, as I said, there were only binaries for most of GEMDOS in that kit; DR weren't about to give away all their source code with it. And the source code for that precise version of GEMDOS seems to have been lost. Also, its hard disc driver appears not to work, at least on my 2/10. Perhaps it works on a 2/5 under certain conditions, but I don't know that anyone has ever demonstrated that it does work. So I took a later version of GEMDOS, code for which has survived and is open source, compiled it against the hardware-specific bits from the porting kit, and added @stepleton's hard disc driver as a replacement for the original. Also some utility functions had to be reconstructed on the basis of other versions of GEMDOS or the 68k port of CP/M. So the precise setup you have there is probably as near as you can reasonably get to the setup that customers of DR would have received, but is not precisely it. It's a composite of surviving code from the correct period and a little bit of modern code. Hope this all makes sense! Quote Link to post Share on other sites

guibrush Posted February 3 Report Share Posted February 3 Hi I managed to make a workflow to write disk on a mac for the Lisa, here is my setup with Diskcopy 4.2 on the TAM: https://imgur.com/STP9QFK but you are right: add files on the disk is a pain in the ass Now, I took a little time to answer to this thread, but there is a reason: I showed your work to Vincent Rivière. Vincent is one of the maker and maintainer of EmuTOS, the free TOS replacement for the ATARI line based on GEM free sources. And Vincent wanted to try something cool. Pushed by the fact that I have a working setup for testing, he started that: https://imgur.com/vzszN7C Quote Link to post Share on other sites

I did post the "historical" GEMDOS to the EmuTOS mailing list when I first got it working, but mostly as a historical curiosity and I've been lurking ever since. Does Vincent have any plans to make this more available? I would love to have EmuTOS booting on the Lisa and I am sure I'm not alone... Quote Link to post Share on other sites
guibrush Posted February 3 Report Share Posted February 3 no, I didn't find a more flexible way to transfert datas. For EmuTOS, of course it will be available For now, we have a booting desktop, Vincent have to improve the interupts and bring the media support to life, then we will have something usable for sure. I come back to you when I know more. Quote Link to post Share on other sites
cheesestraws Posted February 3 Author Report Share Posted February 3 Excellent! If there's anything I can do or info you need / you want me to test on my setup here, let me know. Quote Link to post Share on other sites
guibrush Posted February 3 Report Share Posted February 3 we are currently debbuging, as soon i have something usable I will come back to you. Quote Link to post Share on other sites
