Powerbook 145B 8MB RAM Q

[loplop]

I just received a PowerBook 145B I bought that came with a Finnish System 7.1 install on it. Since I can't read Finnish, I dragged a System/Finder 7.1 set from a clean install of 7.1 (off 1.44MB floppies) onto the HD, and it booted as expected with English as the language.

However, it is only seeing 4MB of the 8MB installed in the 145B. On the Finnish install, it showed "internal memory 4096, total memory 8192" and on the English install it showed "internal memory 4096" only.

So I reinstalled 7.1 off English floppies, choosing the PowerBook 140/145 option. Still only 4096 shown.

How do I get that other 4MB addressed? What does "internal" vs "total" memory denote?

Was Virtual Memory turned on?

Sounds like Virtual Memory. How do you know it has 8MB RAM installed?

Ah, great catch, fellas. Seller advertised 8MB, but didn't show the "about" dialog. I totally forgot System 7 had VM.

My Finnish is crap, but the upper button for VM is clearly clicked, and using google translate I get "ON" for virtual memory.

Darn.

Not related to your issue, but I got the memory upgrade from @Siliconinsider and it works like a charm, as I wanted to use Symantec C++ that requires more than 4MB.

That’s exactly my use case! I ran Symantec C++ in college on my old IIci. I’d like to run it on this PowerBook.

Did you get the 6MB module? I assume the 145 sees it as 4, for a total of 8?

In fact the 145B needs an special memory expansion of 4MB. I tried first with the normal one of 6MB that @Siliconinsider sells and it didn’t work, but then Antoine replaced it by one adapted for this particular model (tell him you have a 145B if you ask him for one)

Great, thank you!!
