I'd like to play with my 3B1's hardware a bit, and have several questions: (1) What are the best manuals to get? I was recommended the Technical Reference, but but have not yett obtained it in two months' waiting. (2) Has anybody interfaced SCSI to the UNIX PC? (3) Has anybody interfaced a larger monitor? (4) Does anyone know how hard it would be to break past the 4M limit on a process' virtual address space? Ie. use more address lines at the MMU? That's enough for now. Andy "Krazy" Glew.

Is it possible to add one or more external hard discs to the 3b1/7300 ? Rather than pay $ 1,000+ for an AT&T memory expansion board, can blank boards be bought (and stuffed with cheap DRAMs) ? Has anyone replaced the 256K memory chips with 1Mbit chips on the motherboard ? Would it do any good to use memory faster than 150ns ?

On March 27, 1987, AT&T announced the production of the SCSI (Small Computer Systems Interface) host adapter card for the 3B2 *family* of computers. This card will allow *ANY* 3B2 computer (i.e. 3B2 models 300, 310, 400, 500, 600) access to SCSI-based peripherals. The only limitation is the software load of the 3B2. The earliest release that supports it is either 2.0.5 or 3.0, and all subsequent releases. I think the original poster is more concerned with the 3B1, which is no relation to the 3B2. Randy
