  1. I'm not sure about the serial numbers, but the Lisa 1 mice had a very narrow button vs the newer ones that were shared with the Mac and Lisa 2's, and also a different DB9 connector hood (no screws). see the photos here: https://www.worthpoint.com/worthopedia/apple-lisa-mouse-a9m0050-early-013519-1863798648 There's a few of these on ebay that are super expensive as well. There is a formula for the serial number of Lisas that tell you the manufacture date and plant in a document called "Good Things To Know About The Lisa.pdf" from SunRem, but not sure that a similar scheme applies to the mice. It does appear that the newer mice that came with the Mac 128 to the plus had a different serial number scheme than what's on the Lisa 1 mice. And to add more confusion, they all have the same model number. I wouldn't go by the serial number as much as the shape.

    GEMDOS on the Lisa can be built again!

    To quote Zoidberg, "I'll take 8!"

    On the Mac (and even LOS), the A-Line traps are almost fully used. You could cheat and use some of the F-Line traps that aren't used by the FPU or PMMU, or perhaps use some other mechanism if GEMDOS allows for it.

    Pity, they missed an opportunity here to call that error something a lot more fun: Major Havoc

    Can you modify the boot loader such that it zeros RAM before it loads the BIOS/BDOS? You should be able to get max ram from the Lisa BIOS low memory globals at 0294: 0000| 0000 0294 MAXMEM .EQU $0294 ;MAX MEMORY ADDRESS + 1 Generally the Lisa's BOOT ROM will load the boot block around address 2000 depending on which device is selected/options ROMs are loaded, but you should be able to know from the boot loader where the boot loader ends, so use that as your start address and zero RAM all the way to MAXMEM-1 using a DBRA loop.

    Thank you @fri0701 taking a look now
  7. yeah, I vaguely remember that HD disks will not work fine because of the coercivity or whatever it's called in low density drives back from the commodore days. I used to order floppies from a bulk maker and for a while the DS/HD were cheaper than DS/DD, but they didn't work well at all in C1541s for example. Perhaps other brands of DS/HD will also work if the disk is degaussed first. This is kinda like punching the R/W hole on the other side of the disk so it can be used as a flippy, but taken to the next level of complexity.
  8. So did DS/HD floppies work well to hold data or did you need to switch to DS/DD?

    Love that command's name! And yes, fond memories of BBEdit back when I was still on an actual mac.

    So this is a bug with the SMF I have or possibly postgres setup with SMF, there's some visible or invisible unicode char it complains about. It only seems to happen from macos x or iOS. The only fix I've found for this, and it's lame, is to paste the text of the code into a pure text only editor such as vi in terminal and then copy it back and paste it into SMF to strip things out. It might be something like smart quotes or emdashes or hard spaces, not sure exactly, there's a description here (must be logged in to see it): https://lisalist2.com/index.php/topic,64.0.html

    Very nice! Are there many CP/M68k apps out there? I know there were a ton for the 8080/z80.

    Lisa Error 45

    Bus error means you tried to access memory that does not exist or belong to you or the MMU hasn't mapped. It's equivalent to the unix segfault.

    That's awesome! Thank you, much appreciated! Hope you used libdc42 to save yourself time, but if you didn't that's fine.

    Good to know ZTerm works! Since the conversion didn't work, just hang on to the BLU images until I fix the bugs, might take a while, but you've done the hard work already. I'll try to image some of my own ProFiles and see what's needed to fix that tool. The last effort I made on that was related to Widgets, which almost worked, but not quite. Likely they both suffer the same issue, though BLU Widget images are slightly different. In terms of LisaEm, yes, you'd need both the boot ROM as well as the dual parallel card ROM for them to show up in the boot menu as a dual parallel card as a bootable option. But once you boot into LOS, LisaEm will lie to the running OS and tell it there's a card in that slot. But you may need to open the LOS Control Panel or Preferences or whatever it's called to tell LOS that there's a card in that slot and it has a ProFile and not an ADMP or some other device - LOS isn't exactly "Plug and Play". There's also some issues with LOS where if you move the drive from one port to another it won't boot and it will return some error like 10727 or like it, so try to keep track of which port each ProFile was used on. I don't believe other OS's have that issue, but then again, right now LisaEm only runs LOS. You'd also want to make sure you set up the preferences to match the type of Lisa you have - i.e. I/O ROM 88 vs A8 and same card slot and upper/lower port. I've seen this issue when moving a LisaEm profile.dc42 image from the parallel port to one of the card ports and on actual Lisas.

    On modern Mac OS X, you can probably use the brew.sh package system to install something like minicom which will work in Terminal.app or iTerm2.app if you don't mind that. Assuming your db9<-> USB cable is recognized by macos when you plug in, it should work, otherwise you'll need to obtain drivers. You might also need a null modem adapter between the DB25 and a DB9<->DB25 on the Lisa and the USB serial cable. see: https://pbxbook.com/other/mac-tty.html for some drivers and advice. I'd give ZTerm a try on your mac and see if it will work, it won't work with catalina as that's a horrowshow dumpsterfire of incompatibility and overreaching totalitarian nightmare security, and possibly spyware now, but if you've got something earlier, do give ZTerm a shot. http://www.dalverson.com/zterm/ I've never tried these on mac os x, but googling around, they seem reasonable, so if ZTerm doesn't work, give them a shot, see which work for you and which have Xmodem built in. https://www.emtec.com/cgi-local/download.php?what=ZOC7 (macOS)&amp;link=zoc/zoc7257.dmg&amp;ext=html http://cutecom.sourceforge.net/ http://www.furrysoft.de/?page=goserial The great thing about BLU is once you get it going, you can control it from the terminal program rather than having to go back and forth between it and the Lisa, and seeing BLU's menu on your terminal program is a good indicator that communications are working fine between your Lisa and your mac.
