More then 8MB on Mac SE/30 with stock ROM

[Berenod]

Hi,

I just received my 16MB (4X4MB) purple ram, which supposedly should work in my SE/30.
As I only have the stock ROM, I kept the 4 original 1MB simm's in bank A, and put the four 4MB simm's in bank B.

Put mode 32 on it (am running system 7.1 on the SE/30).

Weird thing is, the new simm's are operational, but sees the 4MB simm's as 1MB simm's, regadless of wether i put Mode32 into 32 bit mode, or leave it in 24bit mode.
TattleTech does show the machine as 32bit capable when I activate 32 bit mode in Mode32

Any idea's? Tattletech does show 32bit capable, but shows "booted in 32-bit mode =no"

Check what it says in the "Memory" Control Panel, it might be set to 24bit there. But also, I'd suggest installing Mode32 version 7.5.

MODE32 - Macintosh Garden

MODE32 adds 32-bit capabilities to Macintosh models that were capable of supporting a 32-bit architecture, but whose ROM did not. It effectively patches the ROM code in certain models of early 68020 and 68030 Apple Macintosh computers which were misleadingly advertised by Apple to fully support...

I notice it says you need a fresh System install to upgrade to Mode32 7.5, so I would just check the Memory control panel. If that fixes it, stick with the version of Mode32 you have.

And that is why we turn to the experts
Setting "32-bit adressing" to on in the memory control panel did the trick.
Thanks heaps!

Excellent

20MB of RAM is loads for System 7.1. Should cope with just about anything, unless you're planning to edit youtube videos on it

Time to install Prince of Persia and then make a silly animation in Hypercard!

Hypercard, hmmm, scratches head and runs of to storage cabinet...

And look what I found

Lets get cracking!

The joys of vintage computing...
The above version of Hypercard (1.2.5) refuses to run when 32 bit enabled, have to revert to 24 bt/8MB to make it work.

The SE/30 is so much more fun to work with then a regular SE (of which I have two).
Way smoother and faster! Boots in just a couple of seconds, once the memtest is complete.

In combination with a BlueSCSI it almost feels like a modern day computer (considering the obvious limitations)...
I use the external DB25 BlueSCSI, a dream to experiment, and get software on it superfast using a regular computer and Basilisk...

I don't have an SE/30 sadly, but I have an 030 upgrade in my SE. It potters along at a decent speed

I didn't know older versions of Hypercard didn't like 32bit addressing. The copies I have to hand are all > 2.0.

Keep hunting! You never know when you'll get lucky.

I know I did when I finally got my hands on a non-battery bombed machine, with only some very mild cap leakage resulting in but the mildest surface corrosion...

Working/recapped ones start go for silly money, the SE/30 is well on the way ending up the same fate as the Portable (M5120/5126), which are massively susceptible to battery bombs/caps leakage, so the majority ends up simply irrepairable...

There are a couple in the family. Used to use one of them growing up. Haven't seen it in more than 15 years, but it has an 040 these days, thanks to Bolle.

It's wonderful, isn't it? Solid-state storage really kicks new life into these old machines.

FWIW, the BlueSCSI in my SE/30 randomly died this past weekend. I have read time and time again that the BlueSCSI has certain... issues... but had yet to see the real-world ramifications of them until now. It didn't even make it through six months of heavy use before it gave up the ghost.

I have a second BlueSCSI in a second SE/30, which has been seeing usage about as heavy as my main one has recently, so I guess we will have to see how that works out. With my confidence knocked I have ordered a ZuluSCSI to replace to dead Blue. My brother and I have really been putting the SE/30s through their paces recently!

I'm surprised it worked out. I was under the assumption that Bank A must have the larger RAM SIMMs not bank B.

I don't remember that - they used to say put the big simms in Bank B on a IIci to reduce contention with the video RAM, but an SE/30 has dedicated VRAM. Its possible... but it doesn't ring a bell.

I'd be interested to know because the same would likely apply to my IIx.

I don’t think it’s an issue with 4MB SIMMs, just with 16MB SIMMs.
