    SE/30: Micron Xceed Video Card, DB-15 to VGA

    Yes, I have connected to a modern display using some random 10-dip adapter I purchased from eBay. I'm not sure of the make or model because there is absolutely no identification markings on the unit, and I acquired it so long ago that the listing is no longer viewable. It works very well at 640x480 with millions of colors, or 800x600 60Hz with 256 colors using DIP positions 14679 on. The monitor utility lists more resolutions up to 1024x768, but I was unable to get my monitor to sync with anything higher than 800x600. I was going to try the Portrait Display with it, but haven't yet bothered, mainly because once an external monitor is connected, the internal display looses grayscale capability. You'll get an extended desktop, but monochrome only. Of course, I would much rather use internal grayscale. If I want a big screen, I use my IIfx or Quadra.

    My Maccon didn't survive the right angle operation...

    The cyan colored squares are all connected to the ground plane, so they should all be connected. That's probably why it was harder to solder those ones, because there is a lot of copper there. Now your red guys, the squared row on the bottom of your picture should all be connected, too-- they are all +5V (row 37). The top red square, should also be connected to the other reds, as it is +5V as well (B19). The next red square on A22 should NOT be connected to the others. It is a data line. So that is a definite problem if it is connected to +5V. That trace runs along the right edge of the column in your picture, so check for a short at C37, perhaps the solder has flowed into the trace there. Now your next red square on B24, it is also a data line and should not be connected to the other reds. But I wonder if you just marked your picture wrong, as the next pin down at B25 should be connected to +5V. But you don't have that pin highlighted. Double-check that. And finally the next red square at B31, it is also +5V, so no problem. So, assuming you marked B24 instead of B25, the only real issue is the short on A22 to 5V. Good luck!
  3. Sadly, the old thread was lost. https://68kmla.org/forums/index.php?/topic/21280-se40-grayscale-need-help-with-a-carrera-hack/ So, I've gathered some information here to start anew. I have attached v2 of the previously posted hacked control panel. It is untested. CarreraSE40_v2.sit I have also toned out the adapter card, here are the results: All signaling from the PDS30 to the PDS passthrough slot are 1:1 All signaling from the PDS30 to the CACHE slot are 1:1 as well, with these exceptions: CACHE A32 [/ROMOE] is n.c. CACHE B23 [n.c.] is connected to PDS30 B01 [C40M] CACHE B36 [CPUDIS] is n.c. CACHE B40 [CACHE] is n.c. CACHE C05 [/CFLUSH] is n.c. CACHE C07 [n.c.] is connected to PDS30 A01 [/RBV] CACHE C13 [/CENABLE] is n.c. CACHE C17 [n.c.] is connected to A02 [/FPU] CACHE C20 [n.c.] is n.c. Interesting that some signals are ran over the n.c. pins. Finally, I have included some photos of my set for reference.

    Color video from SE/30 for cheap?

    The 81C478 is going to limit the resolution to 1024x768 max. I doubt we could find any of those chips anyway to make new cards based solely on this design, but a set of schematics would definitely help us with a modern equivalent. Probable first steps would be to program a GAL using the equations @Bolle posted, and drop it in. Check for function, and continue until every GAL is replaced to verify what we have is what really is.

    Huh, that's interesting. I have one of those cards... might make for a fun summer project!
  6. Awesome @ants! Curious, did you ever try the Ethernet and Turbo with just the regular SE/30 ROM? I ask because I have had some compatibility issues with multiple PDS cards and the Rominator as well, but the same combination works with a regular SE/30 ROM.

    SE/30 System 6 can't initialize hard drive

    Later in life SCSI luxuries included software selectable SCSI ID. I'm not familiar enough with that drive to know if it supports it, but I doubt any SE/30 era software could configure it. Look for a jumper called TE, it may have been connected to the external case, allowing for the case to control termination depending on if the passthrough was used or not.

    SE/30 System 6 can't initialize hard drive

    No, an internal drive has jumpers to select the ID. Usually they are set for 0, but there is nothing automatic about it. The internal drive must be terminated. Most drives have the terminator packs installed on the drive, but check your drive to be sure. Some have a jumper that set termination. EDIT: Maybe try LIDO or FWB Toolkit to prepare the drive.

    Floppyemu screen blanking out

    Yeah, screen issues for me as well. I took the screen off, and on the back there is some metal clips. I bent those guys in while squeezing pretty hard on the bezel to try and sandwich the screen with a little more force. Not perfect, but its working much better than before. Seems like I always have to adjust the contrast after it sits for a while. EDIT: So this started annoying me even more just now, so I separated the screen from the PCB by unhooking the four metal clips. On the back of the screen is this rubber thing with gold fingers. All the fingers were black. I cleaned it up with a splash of contact cleaner and wiped with a stiff lint-free qtip. Fixed the issue for now, but we'll see how long before the screen starts going crazy again

    Finally got a DiiMOCache!

    Oh yeah, for sure. But the nicest part of the socketed powercache, is the ability to run ethernet and grayscale if you have those upgrades. Before ProtoCache and @Bolle's card, it wasn't possible to have all those upgrades and keep the bucket on. But now, with the new small adapter, the fastest SE/30 with grayscale is probably with that DiiMo card. I should benchmark one day!

    Finally got a DiiMOCache!

    Ha! Indeed. The socketed version is most definitely at the top of the list!

    Such an elegant card compared to the universal PowerCaches. Congrats!

    Cheap IDE on scsi bus solution?

    Okay, SUPER happy with the v6 card now. IIfx, Jackhammer.. WOW!

    Cheap IDE on scsi bus solution?

    Just to confirm, the new firmware and SD card combination has completely fixed my strange write performance reported earlier. On the Jackhammer, I have sustained writes above 2500 KB/s at all sizes. Very happy now with the v6 card.

    Cheap IDE on scsi bus solution?

    Just a quick update... After seeing Cory's results, I couldn't stop thinking there must be something wrong on my end. So I bought a new SD card, and dd'd the old card to the new one. I also see there was a firmware update on the codesrc website that specifically addresses write performance. So I updated the firmware, and along with my new SD card. Poof! No drop out at 60k. Writes now stay speedy! This is in the SE/30, so the SCSI is saturated. I'll try it in the IIfx and with the Jackhammer tomorrow and see if the changes fixed everything up, but I'm pretty happy now.

    Plastic fasteners on Classic analog board sleeve

    They are called nylon snap rivets. Google that term, and you'll find a ton of different sizes. I can't remember the exact size the compact Macs use.

    Cheap IDE on scsi bus solution?

    @Cory5412, I'm using SanDisk Ultra microSDHC UHS-I (advertised with 533x 80MB/s). I'm using this card in both the v5 and (with adapter) v6 SCSI2SDs. Interesting note, when I sent the findings to Micheal, he also had similar results, sharing the graph showing the drop at 60KB on his LC475 running 7.5.3, albeit not nearly as severe as on my IIfx. He theorized at that time that perhaps after 65536 bytes, it falls back to single-sector transfers. In troubleshooting, I tried using both Apple_Driver and Apple_Driver43, but both exhibited the same slowdown. I haven't yet attempted using a 3rd party driver, such as FWB, or an alternate benchmark. I don't have any non-68K machines with SCSI adapters, so I can't really run any benchmarking on alternate hardware. Oh, I guess I could try it in my A3000.

    Cheap IDE on scsi bus solution?

    I absolutely love the SCSI2SD, but I think there is something wrong with the v6 cards. I wrote to Micheal about the issue, and he was able to confirm my results, but sustained write speeds are severely lacking, even dropping to half the speed of a v5 card. Check out these performance graphs. First up, Here's the v6 card on my IIfx using the built-in SCSI solution. Speed averages 1598 KB/s read, with a 850 KB/s write. But note the severe drop-off at 60KB file size. Yikes! Drops the read speed down to 610 KB/s: I thought the issue must be the sub-standard Apple solution, so I tossed in a Jackhammer. Wow, check out those read speeds! 6054KB/s. 4x faster than stock. But wowsers, the write speed again takes a pounding at 60KB file size: And finally, a v5 card using the stock controller. No degradation in the write speed. I still need to try the v5 card with the Jackhammer and see the peak performance it can deliver. But if your use case is writing files over 60KB or sustained writing, something is hosed. I would be VERY interested in seeing results from other v6 owners.

    Radius SE Accelerator Card

    I have the User's Manual and addendum for the 25 I could scan in, but not the 16. They look very similar though: https://archive.org/details/RadiusAccelerator25

    SCSI2SD v6 USB file system

    I use this feature all the time. I've never tried it with the classic-era Macintosh turned on, but once you plug in a USB cable, the drives on the SCSI2SD should just appear if your OS supports HFS. If you use an OS with HFS write support, you won't have any trouble transferring files back and forth. But if you use later versions of OSX, the drives will be read only.

    Regular PDS Cards in Compact Macs

    It's an interesting proposition I've had on the back burner for quite a while. Be careful of those Asante cards, they are predominately for the SE/30. You can find pinouts for the SE PDS slot, SE/30 PDS slot, and LC PDS slot in the 3rd edition of Designing Cards and Drivers for the Macintosh Family (PDF available online). They're all completely different pinouts, but the majority of the signals are the same, at least in name and description. I've been meaning to grab a bunch of jumpers and connect the like-to-like signals from my SE to an LC ethernet card. That would be the hardware portion. Not sure how the software side of things would turn out.

    CiderPress runs pretty well in a Wine Bottle, though. You can get a self-contained OSX app from Retro Computer Australia's download page if you don't want to create your own or be bothered with Wine. http://retrocomputingaustralia.com/rca-downloads/

    M0403 Apple Universal Monitor Stand

    Thanks very much to oldappleguy (what a really cool guy), I received the M0403 Apple Universal Monitor Stand. I couldn't find much detail about the stand online, so I thought I would document a little about it. First off, the underside of the stand shows the model number M0403 near the corner foot. Featuring the Snow White design language trend, the monitor includes horizontal stripes along the length of the base, and small vertical stripes along the front which nicely match the monitors and computers with which it would be paired. The stand includes a platform insert which may be flipped; each side with a differing configuration for use with a compatible monitor. The starburst-like projection on the platform fits into the indent on the bottom of the monitor. The raised T features at rear of the platform secure the monitor by catching the monitor feets. If you are missing the feets on the monitor, you will have a problem with it sliding around on the platform, especially when swiveling. With the Macintosh Portrait Display: And a Machintosh 12" RGB Display: The stand uses a balancing technique to leverage the weight of the monitor for simple force-free tilting, much like later iMacs. A slight ratcheting sound can be heard as the monitor is tilted to and fro. The stand raises the monitor approximately 8.5cm when level, and also features a swivel function for positioning perfection. Interestingly, some documentation found online shows a slightly different variation, without the large platform insert and instead a solid puck. I can find no photos matching that of the documentation, so I wonder if it was ever produced in that manner. All-in-all I really love this stand and it works very quite nicely with a Q700 tower, elevating the monitor above the keyboard and at a height to encourage proper posture.

    Yeah, that looks really good with the IIci. That's a nice setup you've got there!
