    Wiki/Pages article ideas

    Article idea: dip-switch settings for VGA adapters: Beyond the simple tables of “dip switch settings XYZ correspond to WxH” I wish I had some understanding of what particular dip-switches actually mean, in terms of tying together sense pins and sync pulses.
  2. I dug a little more and found a closed 512k auction with what appears to be a M0110J keyboard. So maybe the 512k was first in Japan?
  3. Tech Note #138 says “The 12 point font takes up approximately 100K of memory and the optional 18 point font takes up approximately 250K of memory. The KanjiTalk code itself takes up about 180K of memory. Because the fonts take up quite a bit of memory, many applications will not work on a Macintosh 512K with the Kanji fonts installed.” But TN138 certainly implies that the Plus was the first Macintosh designed for Japanese, and if fonts and text took over half of the 512K’s RAM, it doesn’t seem like it would have been very practical for Japanese use. KanjiTalk may not have been released until the Plus came out. It also claims that there’s a special Plus ROM with the Kanji font, though I haven’t yet checked if either of my Pluses’ ROMs has it. For comparison, here’s a 512k currently on auction in Japan with a non-Japanese OS and keyboard: https://page.auctions.yahoo.co.jp/jp/auction/g370019387

    400k Floppy Drive Lube Repair

    Sure, I’m in no hurry. I have a SCSI2SD for it, and other projects to keep me busy. Electronically, they seem to be fine or mostly fine. They can read and write floppies acceptably. The problem seems to be in the eject mechanism: Manually ejecting takes quite a bit of force on both of them, and neither can be ejected from the Finder or with a mere paperclip. This seems like the sort of problem lubrication should solve. Additionally, one (labeled “32”) seems to have an issue where it half-ejects. The disk can be removed from the drive while half-ejected, but then a new disk can’t be inserted because the mechanism is still lowered. A manual eject is needed to reset it. This could just be lubrication, or might be a deeper issue.

    400k Floppy Drive Lube Repair

    That’s great. I bought the isopropyl and grease already, but I’ll hold off on applying them, then. For the record, I was kind of joking about sending them to you, but it would be totally feasible to ゆうパック them over if you’d find it useful. [Edit: or at a minimum, document their current state as comprehensively as I can, so you could know if it might be useful]

    400k Floppy Drive Lube Repair

    Thanks for the video; I found it very informative. I have two 800k drives I need to tune up, unless of course you want to fix them for me feature them in a subsequent episode

    Sfiera’s Conquests

    Oh yeah, and the SCSI2SD is Hello Kitty-powered:
  8. My new TAM’s hard drive seems to be failed or failing, and I figured I’d pick up an IDE-to-M.2 adapter and replace it with an SSD. Unfortunately, I didn’t notice the unusual screw locations; as Low End Mac notes, “upgrades may require some modification as the mounting holes in the original drive bracket do not match newer notebook IDE drives”. It’s really just a PCB I need to put in place, which doesn’t seem like it should be too hard, but I don’t have tools on hand to make a mounting bracket. What have others done for this case?

    Sfiera’s Conquests

    Plus (4 MHz): in a 512k case. Have a SCSI2SD for it, though I’d like to be able to use it just on floppies. Also have a second in parts. TAM (250 MHz): just purchased, and coincidentally arrived on Christmas. Fat back with USB, but missing its keyboard and everything not pictured. Cube (450 MHz): I’ve had this 3 years this month; everything else is recent. Ran a livestream from it a few months ago. Q700 (25 MHz): jack of all trades. 040 for 68k and a PowerPC upgrade card. It can do LocalTalk, EtherTalk, and IP. Also pictured: a Raspberry Pi 4 behind the router that’s faster than all of them combined (1.5Ghz) and two unibody Mac Minis in the lower left, 2010 and 2012. I’m ready to call the 2010 one “vintage” but not the 2012 one.
  10. Ah, right, I’m mixing up my terminology. I said “userspace” (non-kernel) but I was thinking “unprivileged” (non-root). Needing root was where I gave up with SheepShaver. Running network infrastructure as root on a Pi sounds totally fine to me, but running a crashy emulator as root on my laptop, not so much…
  11. The main reason would be to bridge the physical hardware with emulators. I’m assuming this is difficult or impossible with Mini vMac. I tried and gave up with SheepShaver. If the multicast situation isn’t a dealbreaker, it might even work over Wifi. I assume wireless EtherTalk is impossible, and wired EtherTalk might be impossible in userspace—do you have an idea yet? LToU avpn doesn’t really sound feasible (in the near future? ever?), though an LToU abridge sounds like something I might like to try hacking on. I don’t expect to be able to write an AFP server, but if I could bridge my Quadra to an AFP server running in Mini vMac, that would still be something I’d have a use for.
  12. This is neat and I’m interested in trying it out (after Christmas, maybe…). I’m reminded of two other pieces of software that do AppleTalk over IP, both by bbraun: abridge (source), which bridges AppleTalk between two networks with pcap. It seems like this approach might be usable to bridge LToU and EtherTalk networks, similarly to LocalTalk Bridge. avpn, which is a System 7-9 extension that tunnels AppleTalk over IP. Unfortunately, the source doesn’t seem available. It would be great to get genuine hardware speaking LToU!

    Booting Mac Plus with scsi2sd...

    BalenaEtcher is a substitute for dd. I used to use dd, but I always worried that I’d typo /dev/rdisk0 for /dev/rdisk1 and delete my system. BalenaEtcher only lets you select removable drives. It does complain that the image won’t be bootable, but that’s just because it doesn’t understand the Apple Partition Table format.

    Booting Mac Plus with scsi2sd...

    Have you tried initializing the SD card from Windows? What I did is: Download an image from savagetaylor.com. Use balenaEtcher to write the image to the SD card. Make “Device Size” for Device 1 at least as large as the image. Unfortunately, this will only get you a single drive. savagetaylor.com also shows a method for multiple drives on one SD Card, using a “Save to Device” button in the SCSI2SD util, but you’ve cropped your images. Do you have that button? Maybe you can use it instead of balenaEtcher.

    Booting Mac Plus with scsi2sd...

    FWIW, my SCSI2SD has been working fine with my v2 ROM ($4D1EEAE1) Plus. I’d be interested! I acquired a second, non-functional Japanese Plus which appears to have an International board, though I’m not quite sure what to make of that, since Japan is a 100V country.
