It took me forever to find this, thanks to Adaptec having removed it from their website before they were shutdown/absorbed. While at that point everyone was already using the Windows SPTI mechanisms for 32-bit apps, some of us may still want/need the SDK for writing older 16-bit DOS/Windows...

This is a bit more of a mini-rant at the rather abhorrent state and experiences I've had with the real mode drivers for Adaptec's older, non-PCI cards. Comments/suggestions are of course welcomed, more wanting to share my experiences in hopes that maybe I can spare someone else this same pain...

In order to assist the BlueSCSI sellers in testing their devices, I created this semi-monstrosity known as either the SCSItron or BlinkyTester or something along those lines. It's the SCSI-est thing I've ever made. It consists of a standard 50 pin SCSI input connector, and presents a bunch of...

I picked up a SE/30 that had some pretty significant capacitor leak damage. I had a transistor at Q3 fall off the board from corrosion. I didn't initially see it, but I had pin rot on UE8 that lead to a jail bar pattern on the screen. I replaced Q3, and installed a brand new UE8, and the...

So I've acquired a Jaz USB Adapter (very cheaply, I should add!) which came with an Iomega 25-pin SCSI adapter. Since SCSI is SCSI and USB is USB, it should work as a generic SCSI to USB adapter, no? However as a test I plugged it into my modern machine connected to a Zip 100 SCSI (with disk...

Hi, Just trying to verify an assumption on my part; Is the port on the back of this Zip 250 drive for SCSI? I can't find any indication on the drive itself that it supports SCSI but I can't think what else this port would be for if not for SCSI. Is anyone able to shed some light please?

I picked up a SE/30 off FB MArketplace and in the picture it had the vertical lines and a floppy (interestingly the bars were only on the background - the floppy icon was in tact: But, it's an SE/30, so I figured its is worth trying to fix. I got it home and fortunately, the battery was...

For the future edification of people who might have run into this issue, if you use a Zip100 Plus (the Parallel Port / SCSI autodetecting version) on a SCSI port, the SCSI bus is left unterminated. This will often cause issues with the SCSI bus crashing (in my case on a Mac LC475) and no devices...

(I posted this a couple other places, so apologies if you've seen this elsewhere, and I got some info that may or may not be useful, see end of post) Hi, I have a number if New World G3/4 PowerMacs and I am trying to get hold of a SCSI card to use some late 80-pin U320 drives with tgat works...

I recently got a USB Zip drive that came along with a bunch of other stuff, so I thought getting a SCSI one would be a good way to moving files between my SE/30 and modern machines. Unfortunately, it looks like SCSI Zip drives are relatively rare (at least to find working models). What's been...

Overview The Mac 128k, 512k, and Plus did not have an internal SCSI connector on the mobo. Yet, back in the day, there were solutions. Now, I think there is a great potential to bring that back to use SCSI drives inside those older compact Macs. :) This thread will be the discussion and...

Hi All, @eric (Eric H.) asked me to post pictures of these little devices here. I bought a huge estate and these were in there. I have been in the IT business for over 40 years and these were the only ones of these I ever saw. Eric and I were wondering if someone might want to take a...

Introduction All PowerBook models released up to and including the PowerBook G3 (Bronze keyboard) include an external SCSI port except the PowerBook Duo 200 series. The PowerBook Duo must be connected to a dock of some kind to have a physical SCSI port (SCSI Disk Mode is only supported with the...

Hey all, I've been using a RaSCSI with my SE/30, which worked great until I bought a cheap SCSI cable on Amazon and tried to use it. I apparently upset the SCSI gods and goddesses and now my main boot image won't load. When I try to mount it from another boot disk, it tells me the disk is...

F4 BlueSCSI, a BlueSCSI Fork by Androda (Tech by Androda) https://github.com/androda/F4_BlueSCSI F4 BlueSCSI devices have been available for some time now, in a wide variety of styles: * PowerBook * Standard 50 Pin Internal * DB25 External * Centronics 50 Pin External The software is licensed...

One page document showing the pin layout for easily fabricating a 34 pin to 50 pin SCSI adapter for the Mac Portable.

Hello everyone, I recently installed my Adaptec PowerDomain 2930 SCSI card in my PowerMac G4 (MDD Dual 867MHz) in order to use my Nikon LS-2000 slide/negative scanner. I spent quite some time figuring this out, so I figured I'd share this adventure to help anyone out in the future. I've been...
