A question:
If System release 6.0 is not supposed to work properly on a Mac 512KE,
then why have I been up and running for a week?
I am running a 512KE manufactured in mid 1986, with a Dove 1MB upgrade
and an Apple HD20SC.
The sound manager works fine. (as evidenced by the Sound CDEV and the
fact that it remembers my beep choice.)
I have had many problems with Dollars and Sense 4.1b, but I think this
is due to Monogram's wonderful programming.
Other than that, everything seems to be working just fine.
What gives?
Anything from the Apple guys?
Thanks.
Rob

The Dove 1MB is why. The only real difference (besides the layout of the mother board) between the 512ke and the plus is the RAM. a 512 has 512K, and the plus has 1024K. When I upgraded to a plus, we opened her up, popped out the ROM chips, then popped them into the plus board, and slid the new board in. The ROM is the same, the RAM is greater. So, by virtue of having the 1mb upgrade from Dove, you have, in essence, a plus. -ajw Andy J.

A real Plus upgrade also makes these changes.

Whoops! Sorry about that, I forgot that! And I should remember because I have the old 512KE back-of-the-mac on top of the SE I am using as a souvenir, as well as a nice book shelf. The signatures inside are neat! (The original macs through the plus have signatures molded into the plastic in the inside of the back... rather neat). -Andy Andy J.

Williams '90 |Ack Systems: ack@eleazar.dartmouth.edu| _ /| Thanks for telling me what I already know full well about Macintoshes. Now, what I was referring to was a topic that we had been discussing concerning PARAMETER RAM in the 512KE, and the Plus. According to others, the Plus has some extra parameter ram which some have said is used by the sound manager in 6.0 to store the user's beep choice. Since the 512KE supposedly does not have this extra RAM, 6.0 is not supposed to work properly, hence the existence of the XPRAM init. Unless the Dove board has this extra ram on board, (and no, I dont mean the other 512K, thanks) then I dont see why this is working right. Am I correct in assuming that Dove went ahead and somehow extended the PRAM?

(as evidenced by the Sound CDEV and the >fact that it remembers my beep choice.) I'm going to tell you all a little secret (shhh!). All Macs are not created equal. Just as VW was able to improve the Beetle without changing its appearance, Apple continues to make incremental hardware improvements at the factory (As I'm sure most OEMs do). Since both the clock chip and SCC are pin-compatible, it is a simple matter to use these parts instead of the older ones (and easier to track as well). Since your Mac was manufactured in 1986 after the Mac Plus introduction, it is very likely that you have the newer SCC and clock chip (with extended parameter RAM). So that's why the sound manager works for you. Enjoy! _emt

So that's why >the sound manager works for you. Enjoy! Very interesting...but I bought my 512K Mac three months before the introduction of the Plus! And have had no problems running 6.0 on it (it now has 2 megs, 128K ROMs, and a SCSI port, of course). Is it possible that the newer SCC and clock chip predate the Mac Plus? Anyone have a chunk of source code to test whether extended PRAM is present, or is this even possible? Maybe I should search through IM IV... I shouldn't have the new chips, but since the sound manager works, maybe the tech who installed my ROM/drive upgrade was feeling benevolent?
