  1. Here's what I ended up with. Any chance this will work or will this cable probably have too much interference? I haven't got it to work yet. I had to plug in power externally for the power light to come on, but I haven't made the revision c mod for the term power yet so its not unexpected. I got a log file on the SD card saying it recognized my hdd file and loaded it after I turned it on once, but nothing was recognized in SCSI Director when I booted from floppy emu.
  2. Ahhh that makes sense, thanks for the info! I found this guide that will actually help me more. I made my own guide thats easier to read. I got my BlueSCSI today and got it all put together. Tomorrow I'm going to go to Microcenter and get some Dupont connectors and wire it up that way to test it out
  3. My BlueSCSI has finally updated to departing regional facility after ~2 weeks of sitting in the same place about 15 minutes from my house and I am starting to think about how I am going to connect it to my Dove MacSnap SCSI adapter on my 512k. I have a 26-pin header (f) to DB25 (f) that came with the SCSI adapter and a 50-pin header (f) to 50-pin header (f) that I took from a broken external SCSI drive. I plan on using the BlueSCSI internally and want something that can connect it directly to the MacSnap board. I'm going to try and cobble together a 26-pin header (f) to 50-pin header (f) tha
  4. 68000 in a 512k, just under 40 minutes.
  5. Here is a disk that has all of the laser writer things that were in my system 6 folder. Maybe sticking one of those in there would work? I can't remember if you use system 6 or 7. https://www.icloud.com/iclouddrive/0o_YJHy8-4A-Ae7vCAijTpCzw#Blank_800K
  6. I will run the faster code on my 512k. If I rewrite that in Pascal (I only have THINK Pascal on it right now), would it still be a fairly apples to apples comparison for something so simple? I'll look into getting a C++ compiler if not
  7. Nice, I'll soon have a beast of a 512k with 2MB RAM and an internal HDD. It'll never be outdated I wish I could just stuff an SE/30 inside of it haha
  8. That would be best case scenario, I hope it does. I just assumed that since the Mac Plus didn't, that the Dove didn't. I couldn't find anything saying that it did have it. I also don't have any SCSI devices to test it, yet. I'll report back when I get my BlueSCSI and put it together.
  9. Yup haha, the fan is actually connected to 120V, so the SCSI2SD definitely wouldn't like it. I don't think the Dove board has 5V on it, but not sure. I know the floppy drive has 5V going to it, but probably isn't a good spot to tap into because I will use my floppy emu now and then and I could see that causing some issues trying to power both at the same time. I actually just ordered a BlueSCSI and am going to go that route, but it still requires 5V power. I tested the power output from the floppy drive and got 4.9V, +12.4V, and -13.3V, so I need to adjust the voltage up a bit too
  10. The book you linked is perfect, thanks for the help
  11. Hey, thanks for the tip! I was able to figure out that I can use exp() and ln() with the base libraries. I tried earlier and couldn't get it to work, so thought it didn't exist. I didn't want to have to program in log tables or some approximation method for exponents. I didn't know about the SANE library, which is included in my install. I'll have to check it out and see what all functions it comes with. I have been impressed with THINK Pascal so far, it seems much more modern, easy to use, and feature packed than what I was expecting. Is there a way to view all the functions ava
  12. I have been using my Macintosh and THINK Pascal 4.0.2 to learn more about programming and had some questions for someone who knows more than I do. Most of my knowledge of programming comes from doing data manipulation in Matlab and I've never really had to add much to it because it comes with a lot. I am mostly interested in doing mathematics and THINK Pascal has basically nothing in that regard. It can essentially only add, subtract, multiply, and divide. I am fine with creating my own functions for some things, but am interested to know if there are libraries out there that add some math
  13. I have a 512k with a Dove MacSnap SCSI add-on and was interested in using a SCSI2SD V5.5 as an internal HDD. Instead of routing the 25 pin SCSI connector through the battery cover, I would just keep it inside and connect it to the SCSI2SD and make a bracket for it on top of the floppy drive. As for power, could I power it up a similar way I have my piezoelectric fan hooked up? Right now I have it wired to the CR23 and CR24 capacitors as recommended in Macintosh Repair & Upgrade Secrets by Larry Pina. I realize the fan isn't on 5V like the SCSI2SD needs, but I was wondering if there was som
  14. I just thought I would share my experience with these drives in case anyone else ends up doing what I did. The cable inside the case has a ground plug that is separate and one of my drives came with a tab for it to slip onto. I had two of these drives and neither worked. The one without the tab I had stuffed the ground onto the side of the case to keep it held onto the metal housing. I realized when I didn't plug this ground into anything, the drives would start working. Apparently that plug is there, but shouldn't be used?
  15. Thanks for the suggestion. The only copy I was able to find was for OS 9, though. Looking for it did, however, make me stumble upon DayStar PowerCentral that works on older systems and can benchmark disk drives. The floppy emu read/write is 37.8/31.4 KB/s according to that software. I found something somewhere that said the SCSI on the Plus caps out at ~250 KB/s. So even though the SCSI device would be severely limited on a Plus, it would still be much faster.
