    Synchr030/S 256MB SDRAM Accelerator for the SE/30

    8-layer PCB-that is very impressive! Definitely a lot of work went into this. I'm really happy to see all of the products that are being made to keep our classic Macs alive....and still very much functional! I do have one question about this though- does it have just one pass-through slot or...

    Synchr030/S 256MB SDRAM Accelerator for the SE/30

    This is amazing! I would definitely like to try one out in one of my machines sometime.

    Should I install 64MB or 65MB in my SE/30?

    I like even numbers when it comes to the memory in my computers. In my main SE/30 I have 128MB of RAM; in my test SE/30 board I have 64MB. Either configuration runs well and has no problem running many different programs, including Microsoft Excel 5.0, Photoshop 3, graphics converter, or...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    @JDW -Yes, I ran the tests on a few of my drives, including my Iomega 100Mb: And my external SCSI2SD drive: And I tested other functionality within the program, including it's ability to mount drives, such as my Iomega 100Mb: Seemed to all work well.

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    So I jut got done installing SCSI Director on my SE running O.S. 7.1 off of it's original 20Mb drive. So far i just did a simple test: get SCSI director up and running. And, it appears to run well, instantly seeing the multitude of SCSI devices that I have currently attached to this machine...

    @JDW -what O.S. are you using with SCSI Director Pro 4.0?

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    I've been doing some more testing simple testing, such as running my "After Dark" fish screen saver run indefinitely, including an hour so far today-with no problems. Another interesting test, this: This is an original 400k disk that my parents gave me back in the late '80's with, of course...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    @phipli And a superdrive? Yes! I had both a super-drive and an 800k drive hooked up. The 800k drive was inside the mac and hooked to the front port; the 1.44Mb drive was hooked to the back port and hanging out on my desk. Additionally, here is a shot of my floppy chip:

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    So I tried to duplicate the test results the @JDW had where he was able to read 1.44Mb floppies off of an SE board with only 800k capabilities and.......nothing, womp womp. Maybe there is another fundamental difference between the re-loaded board and a stock one? There shouldn't be, but there...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    This is pretty amazing! I will re-install my 800k SE board in my test machine later today when I get home from work and duplicate this test.

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Sounds like my old job at a local college here in Northampton. They would throw out so much perfectly good equipment; the desktop machine that I use for work that runs Windows 10 Professional came from this place. And despite the fact that it is from 2011, it works just fine, albeit with an...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    @JDW -I had a similar problem trying to run Visual Basic on my machine with Windows 10 Professional. Of course, in my case I also installed a program called "Stop Windows 10 Updates" because I got sick and tired of having everything set up the way I want, and then they through and update at you...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    @Zane Kaminski So I have flashed and tried the.7a-fastscsi firmware in my SE. The good news: As expected, there is a very significant performance improvement in SCSI throughput speeds. The test with firmware .7a-fastscsi is on the right; on the left is a test with firmware version .6f...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    I also did some more quick tests with the .6f firmware, including a perspective drawing using MacPaint 2, as well as running Speedometer. Again, these tests were done with the 1.44Mb Superdrive board while booting off of a 20Mb Hard drive running O.S. 7.1. Additionally, I used the Iomega drive...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Hello All, I did a quick video of my machine booting up, and tried to explain some of the things that I have done/seen and the equipment that I've been using. I had to break it up into two parts to get it to fit here! In this video, it is starting up with the .6f firmware.
