(And, obviously, the R-1000, that sounds like a *very* interesting Be my guest: http://www.designspark.com/blog/a-raspberry-pi-vax-cluster Kind of scary to think something the size of a (double-pack) bridge card set is emulating the "super-mini" of the 80s. Granted, you aren't going to be plugging stuff into a q-bus backplane... My college ran a Sigma 6 with a whopping 1MB of RAM (double the factory spec, somehow, using all four cabinets -- but with each cabinet holding just one 256KB circuit board instead of the original magnetic cores. Needed the four cabinets for the interface -- the Sigma used 4-bank, 4-port /interleaved/ memory, allowing I/O processors to follow (or lead) the CPU in simultaneous memory access. CPU could access address 3 [32-bit word] in bank-4, while an I/O controller is at address 2 in bank-3, another I/O controller at address 1 in bank-2, and the last I/O controller at address 4 in bank-1). But I digress: we used to run between 50 and 60 ACTIVE terminals at peak times on that machine (the Gandalf terminal connection gear was as large as the mainframe; it detected a "connect me" signal from the terminals and linked them to available I/O ports on the mainframe). I doubt a modern Windows box could handle 50 remote sessions with any degree of reasonable response -- even with 1000X the RAM, and who knows how much faster a processor (ignoring multi-core, yet). -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
