Plus Internal SCSI Upgrade Kit?

[Paralel]

Does anyone know if an internal SCSI upgrade kit was made for the Plus? If so, anyone have any specific names that will make it easier to search?

Also, is it a significant tax on the power supply for the Plus? Any risk to it? Are they really hard to find? Really expensive if found?

I've seen a few mods on the net and they all used additional power supplies which I think is the sensible thing to do. I guess it also depends on the power consumption of the hard drive but I wouldn't stress the PSU with any additional devices (especially if you're running an external floppy).

As for commercial products, I'm sure some of the experts on this forum will know.

Internal SCSI on a Mac Plus has more than one meaning. Manufacturers produced alternative SCSI interfaces (ROM or CPU clip-on boards) which were better than the built-in. Some were used in conjunction with internal hard disk drives.

How much power? If you have refurbished the PSU and fit a low power hard disk drive, there is nothing to worry about a SCSI extended Mac Plus.

Edit: Don't run the Mac Plus 24/7 until you have calculated the risks.

Yeah, I meant internal SCSI as in an internal SCSI hard drive.

And yeah, try it but do not push your luck. In Ye Olde Day when third party companies sold internal SCSI drives for the Mac Plus, it was expected that a human being would be sitting in front of the Mac. We are not in Ye Olde Day so we change our behaviour.

basically you can solder a scsi cable to the scsi chip, also use a external psu, and solder that right to the power switch.

maybe install a pie fan in there some where to help with the heat.

I started a thread here.- http://68kmla.org/forums/viewtopic.php?f=7&t=19431

Now that i know much more about scsi cables, with doing the macintosh portable 34-50pin cables, I could get it to work now.

I'm less motived only because i have a really cool 512ke that has been upgraded with a SCSI MacSnap, and a 2mb memory mac snap.

i have a zip drive in there it works out great as a boot drive. and the Zip Drive is great because it will stop spinning if you are not accessing it.

Also Zip drives do not get hot, and they do not consume much power.

Hyperdrive had internal drive kits for the Plus back int he 80's. They were one of the few companies certified by apple to open the systems.

General Computers were the only company allowed to fit an internal hard disk without breaking Apple warranty. Early HyperDrive models required logic board modifications by a dealer or by GCC. Later models, the ones sanctioned by Apple, used clip-on expansion boards.

All good info to have. Hopefully I'll be able to find one of these some day.

Until then, what do I need for an external drive, besides a drive, a power supply, a cable to connect the drive to the external interface, and a terminator? Or is that it?
