    Problem with Total Systems '030 accelerator in Plus

    I haven't taken a really close look at the board with a magnifier or microscope yet, I did take a quick look and didn't see anything damaged, but I can look closer tomorrow. The two garbage screens are from different attempts to power up. Neither is related to any specific set of conditions. I...

    Problem with Total Systems '030 accelerator in Plus

    I have a Plus with a Total Systems '030 accelerator that's giving me some problems, I'm hoping someone here might be able to help. I've had the board for years, it sat for a very long time without being used, and a couple years ago when I tried to remove it from the machine, the plastic Killy...

    GCC Technologies FI/30 internal HD for Mac SE

    Ah ok, thanks for the info. For a moment I thought maybe I could swap the SWIM chip from one of my junk SE/30 boards, but Google quickly dashed those hopes. 🙄

    GCC Technologies FI/30 internal HD for Mac SE

    Somewhat related question... Do you know what is required to switch a SE to support a 1.44 floppy? Obviously you need the 1.44 drive, can you just swap in the FDHD ROMs, or is there more to it?

    GCC Technologies FI/30 internal HD for Mac SE

    Very cool, I had no idea you could (barely) fit an internal HD along with the dual floppies! I wonder if that was a commercial product, or something someone built themselves. Does the bracket have any markings?

    GCC Technologies FI/30 internal HD for Mac SE

    Thanks for doing the digging on that. @JDW did a video series a while back about his 512k with a HyperDrive 10mb internal drive. It's a great series of videos, and he talks about the history of the company in the 3rd video. I browsed through some old MacWorld issues last night as well and...

    GCC Technologies FI/30 internal HD for Mac SE

    I picked up an SE a while back with a non-functioning internal HD. Long story short, today I realized the drive is an aftermarket upgrade from GCC. The machine was originally a dual 800k floppy machine, and this kit came with the drive, a badge for the front, and a strip that covered the upper...

    ADB keyboard left plug problems

    I was working on the keyboard today to clean a couple sticky keys, so I decided to look at the ADB connector while I was in there. All the solder joints looked fine, but I went ahead and re-flowed them and added new solder. I blew out the port with canned air, then DeoxIT, then canned air...

    A battery bombed SE stored in a garage for years

    Awesome work, it's great that you took a machine with sentimental value and decided to do the hard work instead of just trashing it!

    HyperDrive 20 troubleshooting

    I ran across this video yesterday, a guy has a SCSI MiniScribe 8425 that also had a resistor and capacitor next to each other burn. I'm not sure if there is any relation between the SCSI and IDE boards, but I thought it was interesting.

    SE/30 was working one moment, then it wasn't

    Great, thanks for all the help @retr01 and @AmigaOfRochester ! 😀

    SE/30 was working one moment, then it wasn't

    Thanks for the info. I'll replace that leaking cap at C7. Do you think it's worth repairing the corroded traces, or leave it alone along as it's working? I'll check the AB for cracked joints, maybe reflow them out of caution.

    SE/30 was working one moment, then it wasn't

    Yes, it works fine, except for the temporary issue I had yesterday where I had the no-chime and simasimac screen. Do you have any thoughts on whether it's worth repairing, or just run it while I search for another board?

    SE/30 was working one moment, then it wasn't

    Yes, always using 99% IPA. Thanks for the help and the referral! I've looked at the Rominator from BMOW, and just recently learned about GW's ROM SIMM. Never heard of GGLABS. That's something I wouldn't mind doing down the road once I have the rest of the system dialed in.

    SE/30 was working one moment, then it wasn't

    I took some photos with my microscope, it's not great quality but it does better than a phone camera. 001 - 004 are the area around C7. 001 & 002 are zoomed out, and 003 & 004 are the same area but zoomed in. 005 & 006 are taken at an angle to try to see the trace under the edge of C7. 007...

    SE/30 was working one moment, then it wasn't

    @retr01 thank you for the very thorough reply! Yes the LB has been previously recapped, though I don't know how long ago, it was done before I purchased the board. When I get home I will take a close look at the back of the LB for cracked solder joints. I'll also see if I can get a better photo...

    SE/30 was working one moment, then it wasn't

    Things seem to be working fine now. Here's what I did: Yesterday after sitting for a couple hours I plugged the machine in and tried again: no chime, displayed simasimac screen, same behavior as previously. At this point it had no PDS card, and the floppy and MacSD were connected. This...

    Thanks for the suggestions, I'll try to work on it tomorrow and report back!

    SE/30 was working one moment, then it wasn't

    I was using my SE/30 earlier to run some benchmarks with and without a Daystar '030 40mhz accelerator. The machine has a MacSD and recently recapped logic board. The battery has been removed. It was working fine for a couple hours. I was running Speedometer 4.02 to compare some benchmarks...

    HyperDrive 20 troubleshooting

    Thanks for the detailed reply! I took the PCB off and was able to turn the spindle, it rotates freely. When I first turned it I don't recall feeling any "extra" resistance, the heads definitely weren't firmly stuck. I rotated the spindle by hand for a couple minutes hoping that would get it...
