Hello,

Try to find a 68040 and a new PROM :-)
(and then pray...)

> - I got 16 Mb ... other modules available ?
I have 8x2MB. There are at least 4MB Modules, IIRC up to 16MB.

> - If I rember well the 345 can "support" max 48 Mb ... is it true ?
Sounds weird - (at least)64MB or 128MB seems more likely.

> - Suggestions on what and where buy these modules ?
They are pretty rare, some specialized shops still sell them but their 
prices will make you choke...

have fun
