This isn't really a conquests post...I mostly wanted to show show a pic of my SCSI switchbox., and figured the picture would make more sense with context.

I have a SCSI2SD v5 (in the black 3d-printed box) that I use to move files between my macs, modern and old. I'm using a humble old DB25 (parallel port) switchbox to hook it up to different computers without moving stiff giant SCSI cables around.

There is a longer cable with a powerbook 30-pin adapter under the desk that I just pull out when needing to hook up to a PowerBook.

It's not a revolutionary system or anything but it works well for me.

The keyboard is also shared between the two desktops, by just plugging and unplugging the adb cable

You'll need to have enough DB25 - DB25 cables, of course, but i discovered monoprice sells them at a very reasonable price.
I found that the SCSI2SD does need to be powered over USB, it worked intermittently just off the power provided by the scsi cable.

I find it depends on the machine.  My SE/30 yesterday had no trouble powering a SCSI2SD off the external SCSI port.  My PB 540c won't, and I have to have a power source.  My PB Lombard will power it off the SCSI.  I think Mac Pluses are also known NOT to be able to power the devices off SCSI. 

 

I have a bunch of power supplies from SATA / IDE to USB adapters that have a wall plug, a transformer, and the end of the cord is typical NEMA PC power plug, which works great for the SCSI2SD devices.

I don't think it is a problem at the SCSI speeds these old Macs use.

At one time, Apple used a DB25 connector for SCSI (narrow), but this doesn't allow twisted pairs and is not compliant to SCSI standards. Some companies like Iomega still use this connector on new devices.  Such connectors have been noted to have problems on SCSI busses using faster devices such as UltraSCSI (Iomega itself doesn't recommend using more than one DB25 device, but still uses it for Zip drives). The HD50 connector is preferred.

 

Seems like it should be ok since SCSI 1-3 are not UltraSCSI and are slower.  SCSI-3 is 20Mb/s and Ultra-2 is 80Mb/s.

This 6500 has a couple quirks, I purchased it from a member on here, and the internal video does not work, but it happily displays video via a PCI Rage 128 card. But it seems that the video-in hardware does not work without functioning internal video - launching Apple Video Player will play sound coming in the RCA jacks, but no video window ever shows up.
But the case is in marvelous shape.

Well, my 6500 jukebox project continues. I purchased a cheap IDE-SATA adapter, and copied the 6500's system and 60 gb of mp3's to a 120 GB SSD I had lying around...
It boots, but the performance is not great. It takes minutes to boot (sitting on the Happy mac for ages), and seems to be really unstable, as in 'plays one or two songs in iTunes then freezes' unstable.

The SSD seems to work fine on my modern mac, so I have to assume it's something with the IDE-SATA adapter. I put the original 6b HD back in and as a whole the system is much more responsive, which is not what usually happens w/ a hard drive vs solid state.

Well the World's Most Overcomplicated Jukebox is fully functional:

 

I've got 40 GB of MP3's that play great through SoundJam MP.  iTunes 2 is really unstable with a library of that size in Mac OS 9. (SoundJam is...relatively stable).

 

Spotify plays via sound-in on the iPad mini.

 

WhiteCap works as a visualizer as a plugin in SoundJam and a standalone program for the Spotify tunes. The whole thing works pretty well, and I'm able to mute sound via the 6500's remote at my desk. I still haven't figured out track skipping via the remote and I don't know that it's even possible.

One of my old computer collection rules for myself is that everything has to have a purpose or a job...which is really so that I don't just buy All The Old Macs.

 

I have found since my 6500 jukebox my nearby Color Classic isn't doing much. I'm trying to think of a way to use it as a part of my daily routine in my office but I'm at a bit of a loss for it.

It can't do anything (visualizer/MP3s) that the 6500 can (it is a Mystic with an Apple IIe card). It needs a job. (i mean, other than looking charming)

Recently picked up G4 Cube from another member on here...what a machine!


My 17" ADC Studio display that has been sitting around now has a purpose. Only thing that is odd is it works great in 1280x1024 and 640x480, but anything inbetween I get a screen like this:

Now, my memory may be fuzzy, but everymac backs me up, I thought this screen supported 800x600 and 1024x768. Anyone else know?

The icon in the Monitors control panel looks like a CRT so I'm wondering if it's not properly detecting that it's a Studio Display.  You should also have an option for controlling display brightness (if I'm remembering correctly) in there, which I don't see either.  You're using ADC straight in without a converter right?  What refresh rate are you trying to use?

It does say 'Apple Studio Display' in the title bar, so it knows that much. I'm just using ADC direct from the video card, I think it's a rage 128.

No brightness slider, though...so you're right, maybe its not being detected right. No way to adjust refresh rate.

If you confirm it's an ATI card, you might have luck with the drivers here: https://gona.mactar.hu/ATI_Mac/

 

There's a ton of info on that page, but since you have an ADC port you should be safe to use the links under the Apple logos, rather than the ATI logos. 

 

That display should do any standard resolution below its native. Does it exhibit the same symptoms in Mac OS X?

I recently got a gen-u-wine Macintosh TV front plate for my 575 with a Macintosh TV board. One black piece at a time, I guess...the two tone look is a little funny but it works. But i realized the TV uses a caddy CD-ROM, so my current tray loader is blocked.
