Did you turn the Mac off while changing the DIP switches?

The Mac only "reads" the type of monitor connected when it is turned on.  
If you change the switches on the fly, or change the switch settings, then 
restart (warm boot), the change will be ignored. You need to actually power 
up afresh after each change.

Yes. The Macs of that era were known for doing exactly what yours is doing 
when the PRAM battery is on the way out.  Just disconnect the battery and 
the Mac will probably power up ok (albeit with the wrong time and date).

Re: What OS Should my Macintosh SE run?

Yes: I've run 7.0.1 on my Mac Portable (68000, but Mac SE clock speed x 2) 
for over 25 years.  For the Mac Portable, 7.0.1 has always been a "sweet 
spot".  System 7.1 slows it down too much and 6.0.8 is nice, but I miss 
some utilities and apps that don't work under System 6.  There were a few 
little hacks to turn off some of the more resource intensive features of 
System 7 and make the user interface a bit quicker too.  Disabling 
"ZoomRects" rings a bell, but it's been a long time since I "tuned" that 
system and I'm very happy with the way it runs now.

Re: What OS Should my Macintosh SE run?

2018-05-15 Thread Scott Holmes
I agre with superstar64.  System 6.0.7 (or 6.0.8) would be a sweet spot for 
a Mac SE.  Pretty stable and nice snappy performance.  System 7.0.1 would 
work well, but is a bit "laggy" on the SE.

Re: Let's talk about one of Apple's shortest lived product lines...

2018-05-15 Thread Scott Holmes
I quite liked the Centris 650 back in the day.  It was reasonably quick for 
its time and had (IIRC) 3 x Nubus slot.  I used one as a server back in the 
day - a job that it did very capably (File server + FileMaker Pro).

The IIvx was one of those machines that looked great in the pre-sales 
marketing blurb, but the reality was that it did not live up to 
expectations.  Apple short-changed customers by putting the 32MHz processor 
on a slow 16MHz bus.

Re: SCSI Conflict

2018-04-23 Thread Scott Holmes
Pull your internal drive out.  Take a photo of the jumpers with your 
smartphone in case you change the wrong ones and need to put it back.

It should have a group of jumpers to set the SCSI ID.  The PCB screen 
printing will say something like ID0, ID1, ID2 or AD0, AD1, AD2... you get 
the idea.  For SCSI ID 6, the ID1 and ID2 jumpers will be in place - remove 
them and re-install the drive.

Open the "Startup Disk" control panel and select your regular boot drive.  
Reboot.
