  1. Yes, you're running into the DRM. The way you install apps ("Tools") on the Lisa is you have to copy them. To do that you'd insert a tool's floppy (LisaWrite spans two disks and this is a neat thing about LOS is that it understand multi-floppy volumes and handles them properly.) After that you'd select all the icons on the disk by dragging around them, or by using the Edit Menu Select All. Next you'd go to the File Menu and select Duplicate. You'll see blinking shadow icons of the items you said to duplicate. Drag these blinking shadow icons to the destination -
  2. Yes, indeed, that buzz/power off does indicate a short circuit somewhere. Maybe check the pullup/down resistors on the motherboard, or those edge connectors close to ground pins or +5V shorting out with the ones next to them. I've seen these, but haven't done these types of repairs myself. There's was a place you could buy two paints to redo the fingers via electrolisys. You'd apply one layer which I think was nickel or copper, the other was a gold one which was pretty expensive, and you'd paint them one on then the other. I think it was around $100 for a small bottle of the s
  3. Try Tom Stepleton's NeoWidEx to see the number of spared bad blocks, it's possible this profile is at the end of it's life. This utility is intended for Widgets but should allow you to probe the ProFile and see if the spare table is full. It might also be able to low level format it, not sure. Also try BLU (download from here) - it can low level format the ProFile, but you might need a special EEPROM for the z8 microcontroller for that. see: https://www.apple.asimov.net/documentation/hardware/storage/disks/profile/ProFile 5 MB Low Level Format Instructions.pdf and https:/
  4. Yeay! Glad you fixed it! Not sure if it helps or no, but I've had issues with the FloppyEmu and a 2/10. Perhaps it's firmware, but it worked well with 2/5's - I think mine was a version "B" It basically worked to start booting but not after the OS loaded. But I think from the photos, yours is a 2/5. Maybe try from the real floppy, and see if you still get errors as well, if you don't see if there's a firmware change for the FloppyEmu that might help.
  5. There's a bunch of them See the schematic, it's the 74ls283 adders in schematic page: https://lisaem.sunder.net/cgi-bin/bookview2.cgi?zoom=0?page=3?book=6? The adder chips are labeled U8B, and U9B, U10B The SRAM registers for the MMU are: U8A, U9A, U10A, Also the d-flops at U11D. Basically most of the lower half of that schematic sheet has to do with the MMU. (The rest of that schematic sheet is mostly the video circuitry.) If you look on the physical board, there's numbers on top of the board and letters on the left side, these map to
  6. Yup, installing it upside down would provide +5V to GND and GND to +5V. Sorry. But yeah, that address lines go to various decoders all over the Lisa. All of them go through the MMU unless SIO (Special I/O space) is specified with the special "SETUP" latch. This space is used immediately at power on to map the MMU registers, and the Boot ROM, and not much else. The Boot ROM then will setup the MMU registers to see the entire RAM space in MMU context 0 (this is automatically enabled when supervisor mode is enabled as well.) After that, not much else is done with the
  7. So I'm unsure what that could be, but I'd guess there's an issue with the CPU board, or perhaps the connections on the motherboard. Could be anything from a filtering cap to a short, to maybe even a power supply issue where there's just enough power for one board but not both. By some chance do you have access to another motherboard or CPU board?
  8. Did you try swapping slots? does it still work in the other slot? Or is it only failing with both cards in? if so that's really weird. I'm not sure what it could mean when either card works in either slot, but both together fail.
  9. Assuming both boards are 512KB each, then, yes, only one board is being recognize. Note that the MMU is not thoroughly exercised by the boot ROM. So it's unlikely to be an issue with the MMU. The Boot ROM basically sets up the MMU to access the entire possible memory space + I/O and Boot ROM, and then starts to count memory and leaves information in low RAM. At 0294,297 you'll find the maximum physical address, at 02a4-2a7 you'll find the minimum physical memory address, and yes, at 2a8-2ab you'll find the total. So I'd guess either one of the memory slots is damaged, o
  10. You can find it here: https://github.com/stepleton/applenet/blob/502daf70fb9d7d8a5594a588aa4b4893f61f3ecf/applenet_boot_rom.txt#L867 It's in PackBits format I think.
  11. The Lisa contains two serial numbers inside the VSROM - one is the serial number of the Lisa itself, the 2nd is the AppleNet ID which is sort of like a MAC address in modern ethernet cards. These latter ones were to be used with the proprietary AppleNet network cards to identify a Lisa on an AppleNet network. You can see these values by powering on your Lisa, not inserting a floppy, then telling the Lisa to boot off the floppy drive. When it throws an error saying insert a floppy, press Apple-Shift-S to get into service mode, and then select "1" to display memory and then type in 2
  12. I can confirm that it is possible to run LOS 1.x on Lisa 2/5's. When I bought my X/ProFile from vintage micros, CF cards containing LOS 1.2 or 1.1 were included and these boot without issue. But ofc, 870KB disks won't be accessible as the hardware just isn't there. That said you'd absolutely need a working Twiggy drive to image these using BLU. Once that data is recovered in dc42 format, whatever steps are next could be taken. But the first and most important step is to read the media successfully. Even if your existing media might be bad, using BLU you could create cop
  13. So I haven't tried this yet, but vintagemicros has an altered LisaLite adapter here: https://www.ebay.com/itm/Apple-Lisa-Lite-Card-Modified-to-Allow-a-2-10-I-O-Bd-to-be-Used-in-a-Lisa-2-5/143173144110 which says it will allow this to work. You can see the modifications are made by two bodge wires:
  14. I've recently noticed that all of my Lisas (Lisae?) are now showing various video symptoms. At least one is a trimpot issue which should be easy to fix. Another the display over time scrunches up at the top, but is otherwise readable and playing with the trimpots doesn't help. Another goes out of focus. So I've also got a bunch to repair. So it seems whatever these issues are, whether capacitor, voltage regulator, or trimpot, or other, this is roughly the lifespan of the analog video boards. I'd like to collect the symptoms and fixes, and catalog these so I can update the
