    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Additional note. SD Extender is not compatible with BlueSCSI, similarly to SCSI2SD, the card is just not seen at start up. Removing the pull up resistor as reported in a previous entry in this thread is making the card visible to the bios, but then the OS installer invariably crashes during...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    So, eventually I could get BlueSCSI v2 *somehow* working in combination with the HP712 machine. I encountered many issues, sometimes confounded. For confirmation I repeated over and over the same process (fundamentally installation from scratch of both NEXTSTEP and HP/HX, from physical external...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Brief update. I went back to what I knew would work on the HP712, i.e. SCSI2SD. I confirm you need to set the combo 139/4, else the NeXTStep installer will hang. Eventually, I could confirm a working installation of HP UX 10.20 and NeXT Step 3.3 with SCSI2SD. I then moved back to BlueSCSI...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Thanks @eric for the kind reply. As soon as I have time I will try to play with the settings. I confirm that to my experience for the SCSI2SD board in combination with NeXT black hardware, 139 and 4 are the “magic” numbers. Will try to create an account on Discord, too.

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Hello Kay, Thanks a lot for your comments and for sharing the 2Gb image, I really appreciate your support. I will try it as soon as possible. I am sure the hardware is ok: it’s beautifully made, you tested it, it works on a Portable, I’m not even taking the trouble of further testing it on my...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    So, I managed to quickly source a BlueSCSI v2, thanks to the very friendly and effective services of @Kay K.M.Mods. At first, I quickly tested it on a Portable, which runs on a v1 board. Note: I switched from SCSI2SD to BlueSCSI on the Portable, as the SCSI2SD would freeze and crash the...

    Color Classic analog board trouble

    I’d be extremely cautious at taking the flir values as absolute ones. Those cameras work magic, but my professional experience is telling me that there are so many variables affecting each reading… Anyhow, surely they highlight extremely high temperature for the hot components, the charred board...

    120GB SSDs in G4 Cube

    @JDW The adapter I use has of course the possibility to select master or slave configuration. As for the SSD, I just bought the cheapest one I could find on the spot on yahoo auctions, can’t remember, but for sure less than 2k yen including shipment. Concerning the mounting bracket, get ready...

    Tested on two different SCSI2SD, same result.

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    So, some additional info. I just tested the extension cable with BlueSCSI v1.0 on a MacPortable and… it just works. So, I’d say the issue lays on the SCSI2SD device or, more likely, on the combination of SCSI2SD with the extension cable. I guess I will order a BlueSCSI v2.0, which seems to be...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Yes, apparently there’s something wrong either with the flat cable (continuity is OK, though) and / or with the interaction with the SCSI2SD board. I have understood the resistor is a pull up. There’s also a capacitor and an empty slot for a second one. So it’s not just a mere “electrical...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Here’s the link about the resistor tweak. Cable is the very same I got from Amazon. Honestly, not even that cheap and it seems to be executed in a reasonable way. I will try to reflow the soldering, but I don’t think it‘s the culprit. The device is very basic, there are not all that many...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Dear All, I have a few SCSI2D devices since some years now. I recently plugged one into an HP 712. Everything runs fine. However, if I try to use a micro-SD - SD extension cable (I would like to swap the micro SD card without opening the overly fragile top lid every time), the device just stops...

    120GB SSDs in G4 Cube

    Same issue here, the three holes for the heat sink dictate the orientation of the bracket. Which unfortunately is not offering enough clearance for the adapter, since the position of the connectors is fixed. That‘s the reason why I had to offset the SSD.

    120GB SSDs in G4 Cube

    I must be honest, I didn’t check if the plastic frame the adapter came with was fitting or not. But the selling point of the assembly is to fit a 2.5” SATA SSD drive in the boundary volume of a 3.5“ IDE spinner drive. Dimensions are standardized, so, yes, I assume everything would fit off the...

    120GB SSDs in G4 Cube

    The unit came w/o HD, seller only included the heat sink, so I had to source the HD (SSD), the mounting bracket and the plastic rail, which serves the two fold purpose of guiding the unit and locking it to the chassis. I decided to reproduce the rail, the master sample is of course from another...

    120GB SSDs in G4 Cube

    Yes, I only took the active part of the adapter and ditched the plastic case, replacing it with the metal one of the second link. Probably totally unnecessary, but I didn’t like the idea of having the SSD shrouded in plastic frame in a machine cooled only by natural convection.

    120GB SSDs in G4 Cube

    Here’s the solution I use: Mounting bracket Adapter The bottom bracket is a MFJ 3D printed custom design, perfect replacement for the standard one (which went missing). I had to mount the SSD with some offset in order to allow sufficient front clearance for the adapter.
