video of desktop and Dr doodle app running (on real lisa 2/10) https://youtu.be/TDruBwysYoc

tested on real hardware (lisa 2/10 + Xprofile) ... until command boot (my lisa keyboard is faulty with lots of partial pads inside :) )

I found lisa gem binaries years ago (somewhere in old digital research archive that went public from Caldera here for example http://www.deltasoft.com/downloads-gemworld.htm). The gemport file contains lisa binaries. Reading sources I found the way to pack this as a bootable lisa floppy image...

For sure there is a bus error handler in all versions of los and workshop. The code is complex and rely on identification of the last opcode in the  instruction register. I needed to debug the behaviour of the emulator for this. The 68000 core I use is still buggy for some points. I will read...

Lisa is not that slow, it’s 5mhz versus 8mhz for mac but with plenty of ram and a harddrive. Lisa OS is slow but macworks is not and for its time the workshop was a fast dev environment. But does not change the fact it was a failure ;)  my point of view is that the hardcoded mmu is the major...

found the main bug that crashed macworks while booting (version xl3.0). The opcode ADDA.W (A0)+,A0 was not emulated properly. It's a weird opcode because you do not know exactly which value of A0 is taken (for the address it is pre incrementation, but for the final result it's post). The...

The cost was probably not too high. This cobol seems to be a third party cobol ported to the workshop. You just have to port some api and probably adapt a runtime library but since there is already an os and a c and pascal compiler you do not start from scratch. Anyway a cobol compiler was...

maybe this one ? ftp://bitsavers.informatik.uni-stuttgart.de/../../bits/Apple/Lisa/cobol_2.0/ [edit] seems good

Idle does not emulate the rom, rom H (lisa2) or rom C(lisa1) must be present in bios directory (video prom image also for serial number). I wrote in another project an alternative boot rom https://sourceforge.net/projects/idle-boot-rom/ but it's so old and outdated that the cvs repository is...

floppy emu should also work with lisa (with a specific firmware).

The widget has a brake system on its head that might get stuck. The bearings can also get stuck. What can you hear precisely from the widget? something is moving? for your floppy, you can use this one (the external 400k from your macplus will fit perfectly in your lisa (I have the same in...

Oldest versions of my emulator (Idle https://sourceforge.net/projects/idle-lisa-emu) did work with Macworks. But for some reason I get an address error in current version. I suspect a change of behavior in gcc (or maybe I'm firing address errors too frequently). Idle is not perfect but runs...

Tested with IDLE (latest) and Master twiggy images from bitavers.org Seems ok for lisadraw Lisa Write from bitsavers is unfortunatly serialized but the method described (find {T1}OBJ + $42 offset and zero 0 bytes) is ok

Not sure that deserialization is that simple when tools are already installed. The profile image from bitsavers was installed with a serial number (that is longer than 4 digits I think, it's a 32bit 8char hexa value). It may, or may not be one from...

I know that this kind of post is mostly "read only" ;)

Currently converting the emulator to use SDL1.2 and not Allegro4 that is now a bit outdated. SDL1.x is also outdated but SDL2 is not supported on every old platform yet. Port is nearly complete, finding a suitable menu system was not an easy task, the hatari/aranym/Previous minimal menus were...

Hello, to help someone trying to resurect a lisa1 I added twiggy drive support to my emulator (IDLE). Since some twiggy floppy were imaged by bitsavers.org there is some content to test. Emulation is not perfect because clamping/unclamping is not fully tested (& I do not have a lisa1...

even if it's not supposed to be a problem below 2Gb. Try a little system partition of 40Mb on this disc.

there is some echo to this post on a french forum http://silicium.org/forum/viewtopic.php?f=28&t=27478 with the same (un) success...

What is the filesystem type of your external HD, also what is the size and SCSI ID? I think there's a boot key to force boot on a specific SCSI ID.
