    Floppy EMU on Lisa

    An EMU is a train, an emu is a large bird, but a Floppy Emu is a floppy drive and hard drive emulator for Apple computers... It was probably correct for the Lisa. Lisa pixels are little tall rectangles; Mac pixels are squares. When MacWorks draws a Mac desktop with the Lisa's rectangular...

    Floppy EMU on Lisa

    What is the numerical code underneath the crossed-out floppy disk icon? I would disconnect the power cable and the data cable from the Widget for this stage of the investigation. Once we know better what's wrong with the floppy booting attempt, we can hopefully fix that first.

    Floppy EMU on Lisa

    The I/O board test takes much less than a second. I had thought you were seeing a crossed-out I/O board icon. Are you seeing a crossed-out keyboard icon instead? If you have no keyboard, then you will get a "no keyboard" (crossed-out keyboard icon) error. This is normal. Question: during the...

    Floppy EMU on Lisa

    This is a sign that your I/O board could be broken. There can be other reasons for this to happen, but the I/O board is a suspect. Sometimes these faults are accompanied by a numerical code. Do you see anything else on the screen besides a crossed-out icon? Is there any code on the screen? To...

    Floppy EMU on Lisa

    You unplug the floppy drive and plug the cable into the Floppy Emu, which must be running the Mac+Lisa firmware. There is no real elegant place to put the Floppy Emu: for me, it hangs off of a ribbon cable that snakes its way out from the case. When you turn on the Lisa, press a key while the...

    Mac OS 1-5 in swedish?

    The software on that CD is worth a shot, but it may not work for 400k Mac disks (and definitely won't work for 400k Lisa Office System disks) as the use of Disk Copy 6 means that none of the images kept the tag bytes associated with sectors on the disk. Give it a try --- it would be good to know...

    Checkmate Retro LCD Monitor

    Living in a place where space is at a premium, I'm pretty interested in a solution that packs many different types of display capability into a single box. If there's one thing that seems typical of modern-day retro display gizmos, it's heaps of itty bitty cables everywhere, always falling out...

    Lisa 2/10 black screen

    Display circuitry is not my specialty; my next move might be to review The Dead Mac Scrolls and extrapolate the syndromes it describes to the Lisa's video apparatus for more inspiratio. Do you see signs of a glowing heater filament in the tube? It's not always visible but you may be able to spot...

    Lisa 2/10 black screen

    Is there any sign of life from the display at all ever --- do you see any flickers during power-up or power-down?

    Macintosh, Lisa, and IIGS Dealer and Developer Floppy Disk trove

    I haven't looked at them, but the "Sup" disks are likely different editions of the Macintosh supplement disks for the Lisa Pascal Workshop --- that is, the extra materials that allow you to make Macintosh software on your Lisa. We have some of these in places like bitsavers, but I think there...

    Macintosh, Lisa, and IIGS Dealer and Developer Floppy Disk trove

    I certainly don't disagree with locking the disks. The philosophy I'm arguing from is one that minimises the opportunity for mistakes. If you have DC42, DART, and DC6 images lying around, then the day could come down the road when someone decides to pare down the collection. "There are like...

    Macintosh, Lisa, and IIGS Dealer and Developer Floppy Disk trove

    +1 to saving disk images prior to deserialisation. Pace @MrFahrenheit , I would recommend NOT using DART or especially not Disk Copy 6.x for Lisa disks. Disk Copy 4.2 is the way to go for Lisa disks: - DART stores critical data in the resource fork. For DC42, all the info you need is in the...

    9" Compact Completists?

    I think you may also need the Drexel University Macintosh 128: the university required all students to buy a Mac, so Apple made a thousand or so with a D logo on the front cover. My first computer was a Classic, and that's the only compact I need. Still have it, still works...

    Converting internal SCSI emulators to external use

    It's off-topic and very "that guy" of me, but did I just come from the Berenstein Bears universe or is calling what the ZuluSCSI has an "IDC" connector a fairly new thing? To me it's a "header connector", 50-pin, two-row, shrouded in the ZuluSCSI's case. ("Header connector" or "pin header" or...

    You don't have to be too aggressive with hot glue. Hot glue has a natural enemy: the propes.* (* Isopropyl alcohol.)

    Apple Tape Back Up 40SC Not Working

    A pretty classic problem. At least the wheel hasn't done the other thing they sometimes do, which is turn back into petroleum. An IBM 5100 in my collection has a gripless wheel like yours: on that machine, I can press the tape cartridge firmly in the drive and force better traction. If I were...

    Packing Lisa for shipment

    I did almost exactly this (one Lisa was not a 2/10) and spared little expense. Pallet air shipping is a method of choice and it's good that it's available to you. Widgets: extracted and placed in a foam-padded Pelican case, traveled with me in the main cabin in carry-on. Most Lisa OSs will move...

    Doom on 68000 Macs?

    This will always depend on the aircraft, the pilot, and the workload. I've had the privilege to fly a few human-powered airplanes, where in any flight you are putting a few hundred watts of continual effort into the work of remaining airborne, and where the enormous wings mean that control...

    Doom on 68000 Macs?

    I flew a lot of Microsoft Flight Simulator hours as a teenager on a Macintosh Classic, with frame updates dipping down to about 1 Hz around cities. Having since moved on to real aircraft I think it may have been good training to avoid overcontrolling: you put in the control input and then you...
