? MCL 2.0 on a Centris 610

I have recently purchased a Centris 610 with System 7.1 loaded.
Additionally, I have the Macintosh Allegro Common Lisp (MACL) 1.3.2
environment. Well, obviously I needed to upgrade to Macintosh
Common Lisp (MCL) 2.0.1 and I did.
I also have a Macintosh SE/30 running System 6.0.5. I wanted to
get all of my applications running on the Centris before upgrading
the SE/30 to System 7.1, so I was able to run some tests and I
have some questions concerning MCL, System 7, and the Centris 610.
You may gather from the address that I do indeed work for Sun
Microsystems, Inc. But, this is for my own personal use at home,
not for Sun.
Centris 610 SE/30
8 MB RAM 5 MB RAM
230 MB Disk 40 MB Disk
System 7.1 System 6.0.5 (NO MODE32)
I have this Lisp program I wrote some time back that does not use
any of the MACL extensions, i.e. it only performs data manipulation
and simple arithmetic with car, cdr, +, *, etc. This program takes
a fairly long time to complete and so it was a good personal
benchmark to use.
Initially, MACL 1.3.2 wouldn't even run on the Centris 610.
The upgrade, MCL 2.0, performed in the following manner:
1. With Virtual Memory (16 MB) & 32-bit Addressing
The system booted fine with the PTable extension X'ed out
when the system started up. The manual says this is supposed
to happen if virtual memory is used. MCL started fine, but a
fresh compilation of my program produced the following
;[Stacks reset due to overflow]
2. With 32-bit Addressing
Without Virtual Memory
The system booted fine, this time with the PTable extension
running, but I received the same results.
3. Without Virtual Memory & 32-bit Addressing
The system hung after the extensions and the menu bar appeared.
Locked up tighter than a drum.
4. With Virtual Memory (16 MB) & 32-bit Addressing
Without PTable extension (removed from the system)
Same as in #1.
5. When I loaded MCL on the SE/30 everything went like clockwork.
MCL loaded, the system booted up fine, MCL started fine, the
fresh compilation proceded fine without any messages, and the
benchmark ran well.
Since everything ran well on the SE/30 with System 6.0.5 I presume
there is a problem with either System 7.1 or the Centris 610 with
Is this a configuration issue, extensions, etc.?
If not, do I need a patch for System 7.1 for this configuration?
If I need a patch, how may I get it?
advTHANKSance for your assistance and prompt response and sorry for
the extremely verbose nature of this e-mail. It is my nature... :-)
