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

    Next test, I grabbed my external SCSI2SD drive and plugged it in with a copy of O.S. 6.0.8 installed. And again, it fired right up from the external drive, no problems:

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

    So I just got up.....and after making my morning coffee, I powered up me SE with the CD-ROM and Iomega drive attached.....and this time it fired right up! Only thing I noticed odd is that this time when the AfterDark screen saver kicked in it was running slow. Of course not a big deal, but...

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

    @Zane Kaminski -Interesting side note: My Afterdark screen saver just turned on; It is very smooth now. I don't recall it being this smooth before. Maybe that last firmware upgrade had something to do with it? Or maybe something else:

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

    @Zane Kaminski - I am curious to see what happens if I let the machine sit all night and then power it up tomorrow. I think I'll see what happens with that first, and then flash the new firmware in the morning!

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

    The weird thing is that I tried re-creating the conditions of my initial test-booting the machine from a completely powered down state, even going as far as making sure all of the power was disconnected from the machine and holding in the reset button to try to drain all of the...

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

    So I did some testing via the external SCI port....and had some interesting results. I attached one of my CD-300 drives, daisy chained with a SCSI Iomega 100Mb Zip Drive. And when I powered it up......I got a checkerboard. So I disconnected the drives and powered up the machine again, and...

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

    Sounds good. I think that I will wait until you are finished working on the new firmware before installing another patch. Like I said earlier, the current one that you gave me seem to work well. Tonight, I want to test out some functionality via the external SCSI port, like a CD-Rom and an...

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

    I'll try to do that tonight. I applied the first upgrade patch that Zane sent me (I can't remember the revision off of the top of my head) and that patch works terrific.

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

    I don't have a MAc-O-Meter, but I do have an excellent fluke meter that came out of use from a place called Practical engineering. It is my go-to piece of electrical testing equipment!

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

    I did another quick test with one of my decades-old 400k disks; it didn't have a problem accessing it, although the disk itself sounded terrible! I forgot to mention that this test and the test I did with "Creepy Castle" were done on an 800k SE running O.S. 7.1, off of it's original 20mb...

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

    And just to be clear, that video of "Creepy Castle" is with Zane's accelerator in use!

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

    Hay @Zane Kaminski -I flashed the new Firmware before the tests that you see here, and I didn't see any issues! And as far as sound goes....well, here's another video of "Creepy Castle"!: But I still have some more tests that I"d like to conduct. The only issues that I had is that it seemed...

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

    And finally, something fun: A quick video of the game "Creepy Castle" playing while running Zane's accelerator. Sound and graphics are all very smooth! I apologize for the slight over-exposure.

    And here is a screenshot of the Radius 25 vs Zane's accelerator:

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

    So I have been doing some testing on Zane's new Mac SE accelerator as well, and have some results to post! One of the tests I did was to compare how Zane's accelerator performs in comparison to the Radius 16 and Radius 25mhz accelerators I have in my collection. Here is a screenshot of the...

    Interware SE/30 accelerator

    @Bolle -In the past I've benchmarked it against a Micromac Diimo and a Daystar 68030; it is indeed a bit slower, but still way faster than a stock SE/30. If folks want me to, I will happily do some testing and post the results here!

    Interware VDR-1A Cable Pinout needed

    Hey everyone! I recently won an Interware VDR-1A video card. Unfortunately, it didn't come with the video out cable that attaches to the card. Does anybody have a pinout diagram of the cable, or just a picture of one so that I can make a cable for this beast? Thanks!

    Help needed identifying a card

    i think that it's a SuperMac Spectrum/24 series card. You can find more information about them (there are several Series 24 cards) here: https://www.lowendmac.com/video/#sm

    Help Needed - Mac SE/30 giving SCSI termination errors

    I have a board that I just recapped with the same problem. I tried re-flowing the solder to the SCSI chip (the NCR 53C80 PLCC)...and still no luck. My guess is that the SCSI chip is bad and needs to be replaced....and that could be the same with your board too. It would be wonderful if it...

    MAC SE/30 CRT problem

    Ugg, looks like your board had the dreaded Maxell battery explosion! Like others have said the first thing to do is give the board a good cleaning. For something like this, I would use denatured alcohol (available at any hardware store) and a toothbrush. Then check your traces. As long as...
