Here is a complete list of sad mac codes (as far as I know there's no
problem with posting this) It's from the apple developers CD rom, if
I'm not mistaken. It's an excellent guide to sad codes. (it's in
MSword 4.0 format)






This is a text file that describes how to build a case to hold multiple
internal SCSI devices using a PC case. The cost is around $100 (US) and
can hold 4 or more devices. The text file gives possible part numbers and
hopefully answers possible questions from the average user. My system has
been working for >3 months without any problems. If interested, read it.
Flames accepted, but you should at least read it first. I am the author.

Back at the beginning of August I posted a question on the Info-Mac
digest about external video solutions for the SE/30. I didn't receive
very many replies, but those which I did receive were quite good.

Many thanks to everyone who replied. Included below is a digested copy
of the replies, with messages separated by "--" marks.

Sometime near the end of October I asked info-mac digest readers the following:

>I'm interested in purchasing a 15" portrait display for my SE/30, and

>Ehman Monochrome 15" Monitor (w/card): $495 direct
>Mirror Full-page Monochrome Display (w/card): $477 direct
>Sigma Designs PageView Multi-Mode (w/card): $683 campus bookstore
>
> Also, I'm presently using After Dark; will AD work *independently*

I recently posted a question to the net about the Micron card for the SE/30
that allows the internal monitor to display grayscale. I received a slew of
requests from folks wanting to hear what I learned, so what follows is the
main body text from the three messages I received.

Personally, while I was collecting this data I decided my money was better
spent on Think Pascal 4.0 and QUED/M, so it doesn't look like I'll be buying
anything in the way of hardware any time soon, but a big THANK YOU to those
that helped me out.

I recently posted the following questions on IMD:

I received quite a few responses to my queries (a couple of people
actually responded *twice*), and I'd like to thank each and everyone who



MIT EE claims it is benign but confusing. Caveat Solderor...

This document contains notes on the Macintosh serial port and its use, with
concentration on hardware interface issues.

*** DANGER WARNING WILL ROBINSON!!! ***
The DB-25 on the back of a Macintosh is NOT a serial port! It is a SCSI
parallel port. Any attempt to use this connector as a serial port will NOT
function correctly and may cause damage to the Macintosh and/or the equipment
being connected.

The two serial ports of a Macintosh are mini-Din-8 connectors which are
labeled with a telephone (the "modem port") and a printer ("printer port").
This is the pinout of the serial connectors. We are looking at the back
of the Macintosh (or alternatively at the BACK of a male plug):
