@phipli I sincerely and humbly appreciate the cautionary words about the headphone jack output. I really do mean that. And I applaud your persistence and passionate on this topic. I also hold your opinions and work to better the vintage Mac community in very high regard. Thank you!👏 But in my...

If possible, it would be great if you could test audio by installing Spectrum Holobyte Tetris and then listening to the opening music. You can disable or remove WarpSE to see how the audio sounds normally. Sometimes listening through the SE's speaker can be difficult to hear the differences...

@ppuskari I have not tried any of the 0.7 versions yet. I can only say that with 0.6h, the intro music from Spectrum Holobyte Tetris sounds just as good to my ears as stock 8 MHz audio. If you have not used Tetris yet, I would strongly advise you to do so because it helps you detect bad audio...

@Zane Kaminski My intention was to drive to the office (the only place where I have access to a Windows PC) in order to flash “0.7a-fastscsi”, but should I wait for your “b” firmware instead? (i’ve not driven to the office yet. I am actually on my iPhone away from home right now.)

U2E & U2F chip locations use CD74ACT257E, as shown here. U11F & U12F chip locations use SN74LS245NE4 as shown here. U9D used the original HAL16L8ACN chip moved from the stock SE motherboard, as shown here. Schematic page showing the GLU chip is attached as a PDF. My complete BOM is here. If...

I ended up watching videos for two hours last night. I then went back to the SE (which had been powered for those two hours), and I turned up the brightness and tested. No problems found with the mouse. I then switched it off and went to bed. This morning (after a good 8 hours of sleep), I...

Thanks. I did way too many tests and still have more planned. But the fact remains that I spent all last weekend testing with the machine fully assembled like it is now, and I had the various problems I've reported before. That was using a different firmware version for WarpSE, however. And...

Could be. I just got back home. It's been just under 3 hours since I last powered on the SE. The machine is still fully assembled with the case on. I connected my keyboard, mouse, and Model B FEMU. Got a single bong and it booted from BlueSCSI just fine. I then powered off, pressed...

Bad news FEMU Model C triggers the Double Bong too on this SE Reloaded motherboard. 😢 I confirmed that after work tonight by connecting my SE Reloaded motherboard with WarpSE (firmware 0.6h), a mouse & Keyboard, and my Model C connected to the External Floppy Drive connector. Got the double...

No because I eat like a crazy lion so as to have more time to test, but I still don't have enough time on my lunch breaks. That's because I have to pull everything from storage, set everything up, test, then tear it all down and pack it back in storage because this is my workplace and we need...

If you are looking at my scope screenshots, you will see the Power-ON happens, then Vcc rises to 5.0V. RESET/HALT remains low during that time. Then there is another 300ms with RESET/HALT remaining low, and after that it rises to 5v. That is normal. In other words... With or without the...

Not sure. The website here only talks about: 1. New OLED display 2. New SD Card slot (I like the old push-to-eject slot better) 3. Black PCB color 4. New frosted case The adapter you use to connect to the external drive connector is also a tiny bit different from Model B. But like I said...

Steve Chamberlin replied to me by email today suggesting I use my scope to probe Vcc and Reset/Halt on the 68000. I did that but couldn't find any issues, as you can see from my marked-up scope screenshots below. Power-ON Timings (RESET/HALT goes HI about 300ms after Vcc rises to 5v)...

@ppuskari While I have been using SCSI Director Pro 4.0 exclusively “for testing,” I’ve never installed a SCSI Director Pro “driver” on any SCSI drive. My BlueSCSI v1 drive volumes all have the Eric Helgeson recommended HD SC Setup 7.3.5 driver installed.

@iPhil64 Thank you for testing your SE Reloaded board with FloppyEMU Model C. I’ve been testing Model B, but I have a Model C at home. I will bring it to work tomorrow and give it a test on my lunch break!

@Zane Kaminski & @Kai Robinson & Steve Chamberlin: After much testing, the root cause of the Double Bong Problem is the FloppyEMU, even with the newest 20240209 Mac Firmware flashed to it. (Mine is Model B.) The Double Bong problem NEVER occurs on my stock SE motherboard. The Double Bong...

When testing WarpSE-0.6h on the stock Apple SE motherboard while booted into System 7.1 off my BlueSCSIv1, I get these results: (Screenshot is in color because I saved the results file on my SE, then removed the SD card and put it in my modern Mac running Basilisk II, where I made the...

Video demonstration and discussion about the "double bong" problem that currently only seems to be affecting SE Reloaded, not the stock SE motherboard. 😥

I did NOT use the new Baby Face PSU in any of my testing. I have been exclusively using the stock SONY PSU that Kai kindly sent to me, along with the entire SE machine, prior to my SE Reloaded build. I merely cranked up the voltage a bit (but not to max) using the blue POT inside that SONY PSU...

Here's my report for this evening... ==================== 0.6f flashed to WarpSE ==================== 1. Tested my stock Apple SE board in the stock condition, with no drives or WarpSE attached. No Mouse or Keyboard attached either Single bong. All is well. I know it would be, but I needed...
