    Two SE/30 Boards - memory woes

    I had an SE/30 board which had been through some repairs in the past, but which still had unexplainable intermittent issues that did not pertain to RAM sockets or the ROM socket. Leaked fluid had eaten through at least one trace underneath the RAM sockets, and the kind fellow I asked to repair...

    Recapped SE/30 with No Video

    UV solder mask. I guess Amiga of Rochester used that to cover exposed copper traces. Not an issue that I can see. Note necessarily a bad thing at all. My board looks like this on bottom... And like this on top... Again, that's UV solder mask, used to cover exposed copper. Not an issue...

    Recapped SE/30 with No Video

    I'm afraid my eyes aren't quite as speed as needed to follow that fast moving video! o_O:LOL: About the only thing I could spot is extra flux here... But as you can see from my board photo below, it's the GND side of axial cap C2, which isn't an issue... I do see you only have one side of...

    FS: Radius Rocket Clone "Prototypes"

    Another important consideration the Brochure gives us is this... The amount of power required is an important point of consideration. In my IIci right now, I have the Rocket 33 (as an accelerator) with 32MB of RAM on it, along side a Thunder 24/GT graphics card, Apple cache card and 32MB of...

    Floppy drive Sony MP-F51W-23 upper head doesn't touch the disk

    I've never removed the floppy drive controller chip, but perhaps someone who has worked on the SE/30 "Reloaded" build would have experience testing the board prior to having all chips soldered on? @Bolle @Willj I myself have seen horizontal lines under a variety of circumstances, especially...

    Recapped SE/30 with No Video

    Because you mention having a 30Video card, I will tag its creator, @zigzagjoe , to gather his thoughts. You mention having obtained an LCD too, but you seem to have the stock analog board, so I assume you do not have the full LCD kit from ZigZag...

    Recapped SE/30 with No Video

    It's at times like this that having more than one model of the same Mac is very handy. If you only had another SE/30 or SE, you could put your motherboard in that other machine and test it. If all is well, then you could do an Analog board swap. If all is well, then you could know if indeed...

    Recapped SE/30 with No Video

    @MeTheMac You did not mention if you hear a bong when you power on. You only said the screen is dark. A bong would be a sign of life. Next, because Amiga of Rochester did the repair, it would be good to ask him his advice in light of your current symptoms. Do that just to make sure he...

    FS: Radius Rocket Clone "Prototypes"

    @max1zzz That's fantastic news, and I can't wait to see how much better my internal drive performs with a SCSI Booster installed! These are truly exciting times in which we live. In years past we all thought certain cards like the Booster were Unobtanium to all but the most lucky, and now we...

    Compact Mac's feet project

    Personally, if I had a choice between a rather hard and firm foot that sports the Apple logo (which I won't ever see in daily use), or a softer foot that more resembles the original and which I know won't scratch any desks at all, I think Kay's solution is the winner here. Here's what the 2...

    FS: Radius Rocket Clone "Prototypes"

    @max1zzz I see you posted here about having SCSI II Booster card clones in the works. I don't have such a SCSI Booster myself, but photos I've seen show it to be a non-standard high-density 50-pin: The Radius Brochure specifies speed as being 5MB/s. BlueSCSIv2 is a 50-pin SCSI device that...

    Remove and socket SE/30 CPU?

    What heat setting on the FR-301 did you use?

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

    And of course, knowing if the 30Video series cards need a 180Ω pull-up resistor mod like the Booster 2.0 does, in order to use the card in the top slot of Synchr030, would be good info too.

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

    The reason I tagged @zigzagjoe is (1) he created the 30Video clone and (2) he has a Synchr030/S. Of course, there could be other people who have both cards, but I'm not sure who they are. People with both cards are of course the people we need to hear from.

    MARCHintosh 2025 Projects

    Again, it's the clock speed, more than anything else. If you could boost that G3's clock higher, you'd see the benefits. I've got a PowerMac 9600 at the office, which originally had a stock 300MHz 603e card in it (still have that card, actually). It was later upgraded to a 400MHz G4 (7400)...

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

    @MeTheMac While we await word back from @YMK or @zigzagjoe , I would just like to let others reading our dialog know that the "30Video HS" info is found here: https://68kmla.org/bb/index.php?threads/fs-se-30-color-lcd-kits-16-bit-30video-hc.48970/ I also see a similar question asked on that...

    Unbranded joystick - mess inside

    @Javmast3r or @Kay K.M.Mods , would either of you know about this joystick?

    MARCHintosh 2025 Projects

    I don't know what falls under Eric's definition of "Projects" for MARCHintosh, or if this thread is open to talk about "what fabulous things we're doing this month to celebrate it" (as opposed to this thread being strictly focused on major engineering development projects), but I would like to...

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

    BTW, if anyone would like to have the startup screen I made for my video (shown on the SE/30's CRT), you can download Photoshop, PICT and "StartupScreen" formats in the attached Stuffit 1.5 archive.

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

    @MeTheMac Thanks for posting here, as per my suggesting on Reddit. I would now like to tag @YMK and @zigzagjoe to see if they will chime in with their thoughts.
