Hi, Does anybody know where i can get information on how to construct hardware modules that would fit in one of the slots on any MacII**. I am considering building some hardware extensions myself, but i can't find any info on how to do it. All i could find out was that cards must contain some sort of boot rom, which holds a card identification and a piece of boot code for the processor to execute at system reset. Could somebody help me out, or give me some refs to articles, technotes (if any) or books about the subject? Thanks in advance, Rudi Bloks Eindhoven University of Technology, the Netherlands email: bloks @ eb.ele.tue.nl elebrb @ urc.tue.nl

Could somebody help me out, or give me some refs to articles, technotes (if any) or books about the subject? The extension cards in MacII serisare called NuBus-cards. Addison Wesley has published an Apple manual "Making cards and drivers for SE and MacII", that discusses these topics. I'm not guite sure wether there is yet a book for the newer modells also (probably is). Also there are card manufacturers that make NuBus prototyping cards, that have most of the essential NuBus-card functionality built in (like the boot rom and drivers), and spare space to build your own circuits on. Unfortunately I don't have any addersses of such companies (maybe someone on the net does). Theese may get you started.

NuBus interface chipset. Just about all future boards will probably use them. Using them, you won't get tangled up in sombody elses PAL that might just about be impossible to understand.

I would also recommend : - "SN74ACT2440, NuBus Interface Controller", Datasheet from TI. - "SN74BCT2420, NuBus Address/Data Tranceiver and Registers.", from TI. - The Hypercard-stack "BoardID Registration Stack", which you can obtain from apple.com (130.43.2.2) - "Debugging Declaration ROMs", Mark Baumwell, Develop Mag. Jan. 1990. You will also need the MPW CRC-tool and perhaps a ROM emulator. I have developed an interface card for NuBus using these references (and some helpful advices from people at Usenet - thank you all ! ). Morten Paul Pedersen, Dept. of Biology, Univ. of Oslo, Norway.

Addison-Wesley publishes a book about card design for the NuBus and SE expansion slot. In the book there is the address for protoboard manufacturers. The book is part of the hardware and software libaries from Apple. The line also includes the inside macs 1-5 and a hardware reference for the mac line through the Mac II. I have both the design and the reference at home. If you would like the details e-mail me or if the response is great enough I'll post it. Brian Pierson
