no I don't! i own TWO MACS! just got 'em today, as pretty much a gift picked up a Mac IIsi and a PowerPC 7100/80 the IIsi has a network card, but no cdrom - it's pretty much a footrest wtH are them white "slots" in the PPC, where can i get a (free?!) network card for it? lol the 3rd port over looks like a DIV connector for video - if that's what it is, i had no idea DIV was avilable in 1994! (and i still need an adapter) or i need a D15 to mac adapter for a monitor, and chumpusa has 'em, for $55!

Hi tafkact, The IIsi was the first computer I purchased with my own money back in the early 90's. Using it as a footrest or monitor stand today sounds like an appropriate use to me. The network card in the IIsi is in a 90 degree adapter. If you pull it out of its adapter you'll find it fits in the white NuBus slots in the 7100. The single slot on the IIsi motherboard that the adapter sits in is a 68030 processor direct slot. The IIsi has onboard video that uses some of the 1MB of main memory soldered to the motherboard. The amount used depends on the colour depth you choose: B&W up to 256 colours at 640x480. The IIsi requires 4 matched 30-pin RAM SIMMs because it has a 32-bit memory bus. The 7100 has 10Mb Ethernet on the motherboard, but you'll need an external adapter called a transceiver to adapt it from AAUI to 10BaseT or 10Base2. The on-board video is what Apple called HDI-45 if I remember correctly. It was designed to carry both audio and video signals to the AudioVision line of displays. They were a sales disaster and the proprietary AV connection soon disappeared. The on-board video uses 512kB of shared DRAM and is very slow. The 7100 originally shipped with a higher performance, upgradeable video card in the PowerPC processor direct slot next to the NuBus slots. The "High Performance Video" card was a 1MB card with 4 empty slots for 256k VRAM SIMMs (maximum 2MB). The 7100AV model shipped with a non-upgradeable 2MB card that featured an S-video connector and some way of plugging in RCA cables. At some point Apple produced a faster HPV card with 2MB soldered and 4 slots for 512k VRAM SIMMs. I thought it was included in the 7100/80, but Apple's website says differently. Then again Apple's spec database has been known to contain bugs The 7100/80 has a 64-bit memory bus. Its four 72-pin SIMM slots are organized into two banks. To populate a bank you need two matched SIMMs. There is 8MB of RAM soldered on the motherboard. Specs for the 7100/80 are available here: http://docs.info.apple.com/article.html?artnum=112286 If you want any other information, like a recommended OS version or good uses for an old Mac, let me know and I'll be happy to provide whatever I can.

quote: lol, yep in this case it's not what you remember, exactly the main part of the card does fit on the NuBus slot, then there's a cable to the second part, which screws to the back of the case. while it may be possible to use the main card on a nubus slot, there's no place to mount the card that has the rj-45 port on it on the 7100  The IIsi has onboard video that uses some of the 1MB of main memory soldered to the motherboard.

Then again Apple's spec database has been known to contain bugs no s-vid, so the card there must be the other you mention and it does have 4 72-pin ram slots there's 2 major chips on it, one is marked: and the other is: in badly printed white ink on the back are the numbers 630-0895-B0(?)LITED and EL9538 The 7100/80 has a 64-bit memory bus. Its four 72-pin SIMM slots are organized into two banks. To populate a bank you need two matched SIMMs. There is 8MB of RAM soldered on the motherboard. i think the ram is maxxed out, all banks on the board are filled, i have yet to take it apart so i can actually see what they are though Specs for the 7100/80 are available here: http://docs.info.apple.com/article.html?artnum=112286 oooh, good link, mebbe i can find out just what vid card this is ( i still need some sort of adapter) If you want any other information, like a recommended OS version or good uses for an old Mac, let me know and I'll be happy to provide whatever I can. My profile contains an email address that I check once a day. thakns for the info, and yeah, if the hdd doesn't have an OS on it, i'll need something IP: Logged |

A couple other links you'll want to check out: http://www.everymac.com - comprehensive database of specs for every mac-os compatible machine ever built commercially. Better than Apple's, in my humble opinion. http://www.xlr8yourmac.com - detailed instructions on how to drag those puppies kicking and screaming into the...erm, well at least the mid-to-late 90s. As for choice of OS...the 7100 was based on the 601 PowerPC chip, which was the second slowest member of the 60x line released (the 603e being the slowest). That said, you'll want the lightest OS you can get away with. Unless you're trying to run cutting-edge software on it (which I wouldn't recommend without an upgrade anyway) your best bet is maybe even to stick with an iteration of OS 7 -- specifically I recommend 7.5.3, which in my opinion was/is the most stable OS Apple released pre-OS X. ------------------ IP: Logged |

a few of my fav's http://www.shrevesystems.com ^^a ton of old stuff ^^ http://www.lowendmac.com ^^Info on old macs^^ http://www.smalldog.com ^^Apple Specialist, they may still have their HUGE selection of Dayna (which became faralon which became proxim) networking stuff, the kind you would need) http://www.poweron.com ------------------ IP: Logged |

That's the weirdest sounding network card I've ever heard of. The IIsi only has one opening in the back of the case, a horizontal strip the size of an expansion card, so I can't see how the RJ-45 could be located anywhere else. Use of any type of card (PDS or NuBus) required a riser card with one horizontal slot. The riser itself had a socket for an FPU (Motorola 68882) if it was an Apple part. Third parties sold less expensive riser cards without the math chip socket. If that network card is of the processor direct variety then it definitely won't work in the 7100. The only other machine that used 68030 PDS expansion cards was the SE/30. If I remember correctly PDS cards look somewhat like PCI cards in that they have edge contacts. NuBus cards have a connector on the bottom with rows of pins. The RAM may look maxed out, but stuffing a machine with 4MB SIMMs still doesn't give you much. I know the memory controller can handle 32MB SIMMs, I don't know about 64's though. The most RAM I've ever heard of in a 7100 is 136MB. I can't tell from the description whether that's the original HPV card or the upgraded one. If 128k x 8 means 256k SIMMs then it's the original, if it means 512k SIMMs then it's the better one. Either way the performance won't knock your socks off, but it's way better than DRAM video. The best DB-15 to HD-15 video adapter on the market was the free one from Viewsonic. It shouldn't be too hard to find a 10BaseT transceiver. AAUI was used on many Centris, Quadra and PowerMac x100 series computers and at least two models of LaserWriter printer. OS wise I wouldn't go above 8.1 unless the machine is loaded with RAM. Later systems have a tendency to eat 15-20MB of RAM just booting. That's not easy to live with if your Mac only has 24 or 32MB total. Virtual memory is a partial solution, but it really slows things down. Not until MacOS 9 did virtual memory get reasonable and much of the improvement was the development of faster hard drives. I can't agree with Akira on System 7.anything for a PowerPC based Mac. 7.5.3 was good on 680x0 machines, but in Power Macs was a real dog, and using virtual memory in System 7 is like watching paint dry, only slower. I agree with the last poster about Small Dog Electronics. I've had several good experiences with them. I think they got rid of the old networking inventory about a year ago, but they tend to carry lots of refurbished equipment and end of line merchandise in addition to new stuff. IP: Logged |

wait a sec!! now i own THREE Macs! the IIsi, the 7100/80 i mentioned, and now a 8100/110 and i got the 8100 online! i'm making this post from it! whooo hooo!! first post!! hehehehe!! i'm also using a lot of exclamation points!! like this!!!! LOL! edit (on a PC): so i unplugged from router and went to a hub, rebooted and now have no 'net!
re-edit: ok, the router shows the MAC address of the Mac, but no name - so i KNOW it's at least getting the signal... anyone have ideas for fixing? re-re-edit: IP: Logged |
