    Color Classic / LC575 Upgrade / Dead Internal SCSI

    Oke, clear. I can now only think on a „no connection“ in mechanical way: internal SCSI cable bad, maybe solder joints of the connector on the logic board are bad or a connector pin is bend or broken off. SCSI chip sould not be the problem, because it starts up with external SCSI.

    When you have it startup with the external, does the internal mount?

    Color Classic / LC575 Upgrade / Dead Internal SCSI

    The other things I could think of: is the terminater jumper correctly set on the BlueSCSI and are there maybe SCSI ID conflicting between the internal and external SCSI‘s?

    Color Classic / LC575 Upgrade / Dead Internal SCSI

    Does the internal BlueSCSI get power from the molex cable or only over the connected SCSI cable?

    My Mac Plus Hyperdrive 20 recreation

    Well, I did some testing on the Mac Plus board that seems not to boot and only bongs. It turned out to be a volage problem. I messured on pin 6 about +4 volts. So I adjested the voltages that I have about +5 volts on pin 6. The Mac Plus board now boots and started up as if nothing happend. Still...

    My Mac Plus Hyperdrive 20 recreation

    I saw it on eBay, too. But accoording to the installation manual (page 23, see picture), there is a specific difference between a 512K board and a Plus board. The one on eBay is a 512K board. Althought the seller who I got my parts from claims that it all came from a 512K. So maybe a Plus board...

    My Mac Plus Hyperdrive 20 recreation

    I made some photos, one of the way how I connected te Hyperdrive LB and two of the Plus LB I screwed up. Based on where the 5V and ground were, I fabricated a temporary cable with the help of a standard molex<->mini molex. On the mini-molex side I plugged in the cables that goes to the molex...

    Color LCD Retrofit Kit for SE/30 by ZigZagJoe

    Oke, thanks for this info. I will think about it. My SE/30 is quite "modern" yet. Recapped LB, Maximum RAM, BlueSCSI 2.0+Wifi, Rominator II and last May 22, I bought on eBay your PDS Slot Booster 2.0 Accelerator. So there is no technical obstacle to build in this Color LCD Retrofit Kit. I see...

    Color LCD Retrofit Kit for SE/30 by ZigZagJoe

    I‘m sure this kit is worth spent the money on. But as a buyer from the EU, I have also to pay VAT from 21% over the total cost with items from outside the EU. That makes it even more costly. And I don‘t have any options to work around it to avoid this VAT. An options that could make it more...

    The Hyperdrive PSU I have can be switched with a cable between 120VAC and 240VAC. It is on 220VAC. And It is still not connected to the analog board of my Plus. I powered it with a cable right out of the 220VAC outlet (right next to where the Mac Plus was connected). No, I powered only the...

    My Mac Plus Hyperdrive 20 recreation

    Well, this project has already to major disasters. I got new caps for the CPU. Soldered them all in, but unfortunately that didn't help. Still no 5 and/or 12 volt, even with the potmeter in different positions. There is a lot going on the the 220V~ side of the PSU board, but on the DC side...

    The project continues slowly. I did some testing and measurements on the PSU. There is clearly activity, but not on the DC side for the 5 and 12 volt lines for powering the board, HD and fan. I ordered some new caps (6) and ferriet core line filters. The Hyperdrive LB is already build in. I...

    Macintosh IIfx 68030/50Mhz???

    In the IIfx, all the systems and parts working together in a highly efficient way. Changing 1 or 2 things can simply cause that it wont work anymore.

    For now, I let the jumbers in the position they are. I don't have the tools or the knowledge to read of backup the ROMs on the Hyperdrive board. Still thanks for reaching out to him. I keep it for now to the jumper settings as they are. It works in a 512Ke, so I don't see reasons te believe it...

    Thanks for this info. It is indeed helpfull. If this works on your 512Ke board, than the jumper setting on my board should be good to go on my Plus board as well. It could be that the 512K where this system comes from was in fact a 512Ke, with the same ROMs as a Plus (I only bought the...
