    What's on that old hard drive?

    Floppy discs from a thrift store had a local bank manager's memos regarding an under-performing and manipulative employee and complaints about her. The business doesn't exist anymore, but the manager still works for another company. I disassemble my old HDs and save the magnets. I think people are more careful now about HDs than they were 10yrs ago.

    SCSI2SD external cable type?

    Yes - that's what I want to do too. I found an empty external SCSI enclosure that I'd like to try to use with the SCSI2SD. I think that will work - but won't look as great as a custom one. Straight through parallel cables should be easy to find at a thrift store and easy to validate with an ohm meter.

    Awesome - thanks!

    SCSI2SD external cable type?

    I'd love to see a step by step of what you did. I still have an SCSCI2SD that I need to install and will likely run into all the same problems you did!
  5. Ironically, I think it's easier to do with a PC. I was hoping some Apple users would chime in - I know Mini vMac and SheepShaver/Basilisk runs on a Mac - I would go that route. Otherwise, you could network the Plus using AppleTalk and transfer files that way - or a Zip/Jazz drive - or a bridge Mac. I think the easiest method is to use the emulators - there's a bit of a learning curve at first, but it's worth the payoff.
  6. How I would do it (from a PC): Download any of the DSK files from Gryphel (or create your own with HFVExplorer ). Run SheepShaver with OS9, and select Enable "My Computer" icon so I can browse files on my PC. Mount the blank DSK. Once running OS9, load up the blank DSK with your files. The video shows PlaySound as the application - I don't know that app, but I assume you can find it somewhere (here maybe). Here's a topic on playing music on a compact Mac. I wasn't able to get Mini vMac to run PlaySound - it complained that I don't have a co-processor.

    Another DIY ProFile emulator

    Would one of you smart guys build a Raspberry Pi Hat that connects to a Macintosh wiring harness?
  8. It's from a fellow in Sacramento. The RAM is factory, and the ROM has one broken clip - hence the brace. Now I have three logic boards to recap (and only one set from Trag). Any recommendations for getting the oxidization off the chip legs? I tried a toothbrush and isopropyl alcohol, but the discoloration remains. I'm still too chicken to put it into dishwater and scrub it.
  9. It's either a standard flyback Tx or a low volume nuclear device. Matsushita = Panasonic - who knew?
  10. I noticed that too - not sure why that's there - maybe it has to do with the CRT. The flyback Tx is all standard.
  11. How many SE/30s does one person need? Apparently, always more! (Somebody stop me.) I picked one up today, and the owner wanted to plug it in and show me that it worked - I said, "That's okay. I'll buy it even if it doesn't work." So I get it home, open the back, and find a LOOSE hard drive - someone had TAPED it to the floppy sled. Then I pulled the logic board, and fortunately, the battery was intact, but there was something missing. Also, there was an odd bracket between the battery and the ROM: Odd no? I'm still not sure if that's glued in or what. Also, notice something missing? It has a CRT that I didn't recognize too: Non standard? Made me wonder if it had been replaced - or maybe the later SE/30s came with a Matsushita. And as I was cleaning up the board a bit with C3H8O, two of the capacitors jumped ship, so I decided to pull the rest of them. And I was expecting 11, so was surprised when: TEN capacitors. Is this just a later logic board? Where's #11? Well, as you saw above, C12 made an earlier exit. Also just noticed the odd man out in the RAM - I wonder if the original owner ever had RAM issues due to that 9 chipper. Anyways - just a reminder not to plug it in and see what you get. Here are some more photos of the board and such: How can you tell what size RAM that is? I can tell on a PC from 1988.

    Mac Plus and Floppy Emu HD20.DSK

    Thanks! I recently put together some notes on the Floppy Emu that might help future Mac liberators: Steve at BMOW has yet to add the directions for setting up the HD20 in the Floppy Emu user manual (as of 2018-08-01), so here it is. The HD20 option works well for a Macintosh Plus or an SE, but not great for a Mac 512k or a Mac SE/30, and not at all for an original Mac 128k. For the Mac 512k, you can use an HD20 hard drive, but you first need to boot from a physical floppy disk in order to load the "HD20 Init" - so it can see the HD20 drive. For Mac 512k's with FUBAR physical drives, that's a problem. Steve says: "The Mac 512Ke, Plus, SE, Classic, Classic II, Portable, IIci, IIsi, and LC-I have HD20 support built into ROM". You can use any sized SD card for the Emu, but you want to limit the size of your virtual Hard Drive, because 1) you won't need 2GB for System 6 or below, and 2) it takes longer to load larger disk sizes, and 3) it's easier to copy the disk image back and forth when it's small. For System 6.0.8, I used the blank 224M.DSK file from Gryphel, because I found that a 20MB is not big enough. Rename your disk image to HD20.DSK (the name doesn't have to correlate with the disk size). It's easy to create your own blank DSK files using HFExplorer, but I won't go into that here. Mount the HD20.DSK image in Mini vMac. Mount the System installation files for the OS that you want to install on the HD20.DSK. I used 6.0.8, because I'm using it on a Mac Plus. Run the System Installer for the System software, and choose your HD20.DSK as the target - and install the system. For 6.0.8, I mounted all four *.IMG disk images before installing so it wouldn't ask me for Disk 2, Disk 3, etc. Now copy all the apps/games you want to the HD20.DSK - you can see why Mini vMac is so helpful here. Your HD20.DSK is ready to be copied to the SD. All(?) SD cards come pre-formatted with FAT32. Floppy Emu requires the SD to be formatted with FAT32 - make sure that it is. Copy the HD20.DSK to the root of your SD. Put the SD in the Floppy Emu. Plug your Emu in to the vintage Mac external floppy port, and start the vintage Mac. The Floppy Emu defaults to floppy disk mode. To change the mode from floppy disk to HD20: Press the Reset button, then press Select. You'll see a list of modes, one of which is HD20. Use the Next button to scroll to HD20, and press Select. It tells you to reboot the computer. Make sure the floppy drive is empty, and reboot the computer. You now have a bootable hard drive. Update the Floppy Emu to the latest firmware Steve's instructions are broken into two parts, probably because he thinks of them as two independent things. However, for us end users, this is one process with several steps. Here are instructions that work better for me: See this video demo of the firmware update process. Download and unzip the latest firmware from BMOW for your particular computer (Apple II, Mac, or Lisa). Copy the files, firmware.xvf and femu.bin, to the root directory of your SD card. Insert the SD into your Floppy Emu (attached to the computer), and turn on your computer. Hold down the NEXT and PREV buttons, then press and release the RESET button, still holding NEXT and PREV, until the CPLD firmware update process begins (about 3 seconds). Wait 10-15 seconds for the process to complete - the status LED flashes while updating. The LCD displays "RESULT: SUCCESS" (Note: this does not complete the update process). If you see a "wrong CPLD" warning, don't worry; this is normal. Hold down the SELECT and PREV buttons (Note: these are not the same buttons as before), then press and release the RESET button, still holding SELECT and PREV, until the AVR firmware update process begins (about 1 second). Wait 5 seconds for the process to complete - the status LED flashes while updating. When finished, the LCD displays self-test information and the main menu. Confirm that the new firmware version number displays on the self-test/info screen during startup.

    Mac Plus and Floppy Emu HD20.DSK

    Ben, I know what this is - it's because you only set up the CPLD firmware and not the AVR firmware. Download the latest firmware from BMOW, put the XVF and BIN files on the root of the SD, then follow the instructions for updating the CPLD (just in case). Now, you probably won't get the "wrong CPLD" warning, like the directions say, but that doesn't mean you can stop there. There's a SECOND PART TO THE FIRMWARE FLASH that you need to do, intuitively labeled "PART 2". Follow those directions, and you'll be all set!

    Mac Plus and Floppy Emu HD20.DSK

    I should mention also that floppy images work fine it’s just the HD20 that doesn’t seem to work
  15. I have an older version of Floppy Emu (v1.2). I have copied a 20MB DSK file (from Gryphel) to the root directory on my SD card, renamed to HD20.dsk. When I start up the Mac Plus, it doesn't recognize it. In fact, the Floppy Emu doesn't see it either - it doesn't list it on its tiny screen. I have updated to the latest firmware: App Version 1.0 L CPLD Firmware 14 (Mac Floppy + Hard Disk and Lisa 2/10 Floppy firmware, for all Floppy Emu models: hd20-0.7H-F14.5) And it said it updated successfully. In Steve's video, he shows a Select Default Mode menu when you press Reset. I don't see that at all - it just lists the folders I have on root and DOESN'T list the HD20.DSK file - is it case sensitive? Any ideas?
