  1. I've not seen this discussed, I'm curious about the TAM community's obsession with USB/FireWire cards. The IDE/ATA1 performance bottleneck has been my main concern since the 6360/G3 L2 was my production machine. It was hacked to house a full length PCI VidCard to drive my TPD and conversion to 6400 riser was next on my hack list. I viewed USB/FW on Sonnet's TEMPOtrio as very welcome, but unnecessary features added to Sonnet's stock Tempo ATA-Whatever HDD interface cards. As we have determined, the trios' incompatibility with the Gazelle boards I've been collecting, I'll be opting for Tempo/133 over USN/FW. I'm curious to see if ATA-66 or ATA-133 on Alchemy might trump Gazelle's (TAM's) 25% bus bump benefit play. When the TAM was new, FW400 was in use for Video and such, but AFAIK it's not suitable for Hard Disk I/O increases for Gazelle. and replacing TAM's 3400 bits with a far superior USB KBD/Mouse combo would be wiping Ive's lipstick off the pig. While replacing the HDD with Compact Flash/Adapter's seek time reductions make the TAM zippier, Gazelle remains hamstrung by Apple's rudimentary (and flawed) implementation of IDE/ATA1. An ATA66/133 interface card cabled to a PATA SSD (or even CF) should shoehorn within the TAM's confines? Throuput increases aside, burst mode increases should take CF/SSD benefits to new levels of TAM zippiness, no? Anyhoo, links to such discussion would be most welcome, especially if someone has taken this route and benchmarked performance. Has anyone here made the switch?

    Ricoh chipset PCI to PCMCIA adapter card - possible?

    So far so good. Advantech support told me there are no jumpers on this card's schematic, but I'll have to wait until Wednesday to talk to the tech who directly supports it. It's the only three slot riser I've found that might work in Alchemy/Gossamer for implementing Slot C1.

    Sonnet Crescendo G3/L2 in TAM Not Working

    Glad to see this thread reappear! I've been playing with two 400/512K L2s in a 6500 and what I'm hoping is my 6400 board. I'm also hoping it's just a corrupted driver as both machines boot fine with either card installed, but the driver shows up as disabled. I'll have to try thermal compound, but that wouldn't be an issue until cards warm up a bit would it? Don't recall info on paste being the culprit at boot, IIRC it's associated with erratic behavior under use? That's what has me confused here, I'd think it would stay cool enough to pass POST and the boot process before wigging out? Does the accelerator shut itself down to avoid damage when it exceeds safe operating temperature? Wondering if I might have cooked both cards during testing? From the box and spec, pretty sure I picked these particular cards up as NOS from Sonnet when they cleared out accelerators. Hoping to find the 6360 board with the original Crescendo ???/1MB L2 in working condition. edit: Oopsie, forgot to mention I'm running with/without a dead PRAM bat. Gotta build a couple or three, Does it really matter so long as the machine stays plugged in, other architecture seem to retain PRAM setting in that state? I'd feel sorry for the TAM gang because you don't have room for a battery holder, but if you've got the money to be messing around with a TAM, those batteries don't seem all that expensive. One more! Both my boards booted right up with chimes a time or two, then sound died entirely. Is that "normal" behavior for a board that needs a recap? I have cans on my 6500, did Apple use leak-free caps on the TAM boards or are you folks recapping? There's a can right next to (for?) the Cache slot. Could this be the culprit? Low voltage/instability of its slot would seem a more likely nasty at boot than paste to me. Cache cards use a piddling amount of power as compared to an accelerator and haven't got the intelligence to shut themselves down. Forgot to mention that my Cache DIMM appear to function fine where the Sonnets don't.

    LOL! Never thought I'd be looking at DCaDftPMF or the PCI spec, but there it is! They all must be unique to each slot. If I can get my slot snooper to tell me how to set up INTA-D for CS2's Slot E1 we might try something very interesting. Static signals not found on CS2 pinout (they'd be implemented on the logic board as CS2 is a subset of the PCI spec?) INTA = header pin 1 INTC = header pin 2 INTB = header pin 3 INTD = header pin 4 Active signals on CS2 that match the other four lines required to be jumpered from the nubbin cards to my 3 slot riser: CS2 pin 101 - CLK = header pin 6 CS2 pin 92 - GNT = header pin 8 CS2 pin 91 - REQ = header pin 9 CS2 pin 78 - IDSEL = header pin 10 I'm guessing the CLK signal needs to be on the same length jumper as REQ, GNT and IDSEL for them to latch to the leading edge properly? INTs are what it's all about ATM, that and cutting down one of my single slot 1U RA adapters to fit into the Comm Slot. If I desolder the connector and install four headers that's half of the Slot $E1 equation. There's nowhere to hijack signals from the phantom Slot C1, that'll have to be checked by using the only riser I've found that has no jumper cards. The only thing that makes sense for that one is that it goes into A1 and rolls its own B1 and C1 from there. That's a tech support call for the morning, but just maybe I can get the riser I have on hand to speak E1 at some point.

    Curioser and curiouser. Slot A1 (lower connector) of the 6500 riser works in slots A1, B1 And C1 in my BG3DT testbed, It takes on the Slot ID of whichever host slot in which it's installed. Video card in upper Slot B1 of the 6500 riser boots with proper display up to the point of freezup after the first extension loads. With Extensions Manager activated with the spacebar the control panel loads, but ADB ceases to function. Removed the EM control panel and the system freezes up at about the same point. Holding the spacebar dow fails to load the System with extensions off, somewhere right before that ADB gets poleaxed and the first extion loads and freezup occurs.. Again, it's amazing to me that the VidCard's working fine off drivers in ROM When installed in 6500 riser Slot B1 in whatever host slot I try, but having it chime in at some nebulous Slot ID (WAG) borks the boot process. I'm using a 1U single slot RA riser to tip it over to the right so the cards are upright. With the right side panel removed, the kluge sticks out the side of the plexi case. I'll keep hacking away at the problem from the standpoint of the nubbin card's jumpered signals for the heck of it, but since the physical slots don't exist in the TAM/Gazelle/Alchemy machines, I think I'm at pretty much of a dead end with this riser. I was hoping that the 6500 riser inserted in slot A1 of the G3 board it's B1 implementation in the top slot might work. Not the case. It's time to look into snagging a three slot riser without the jumper boards. Guessing they're intended to install in the most inboard, Slot A1 to save space and will be set up to automagically splay Slot A1 out to Slots B1 and C1. With some luck it will "just work" to implement the architecture's ephemeral Slot C1, may be worth trying? BTW, the slot snooper's LEDs work so I got polarity of the basic circuit right, but I'll need to try it with a single jumper/LED readout at a time. Getting STRANGE results that make me think the circuit needs diodes for isolation downstream from the LEDs. Getting all VERY bright in A1 of the 6500 riser, but all VERY dim in any other slot, including Slot A1 of the Beige. Most strange.

    One more then off to work: With a customized twin slot PCI Riser in place of the CS2 NIC/Riser, about how "tall" could a low profile PCI card be while still fitting within the sloped Fat Back's cubic? KISS compliant approach would be a modded 6500 type riser. Gigabit NIC and Vonets WiFi. With low component height on the lower card in Slot B1, slot to slot distance might be reduced considerably. Dunno, just wondering about it.

    Ricoh chipset PCI to PCMCIA adapter card - possible?

    Back to TAM networking basics: First off, did Apple design the TAM so that a Sonnet Crescendo L2 that had been available for 6360/6400 would fit within the confines of the standard back or did they opt for a "profile under function" approach, leaving only enough room for their Cache Card and low profile memory? Byrd, could you check something out for me? I need to know how much clearance there is between the top of the PCI slot connector and the standard back? Is it as least the height of the Sonnet L2 accelerator cards? If you could make up tall mockups with thin cardboard of a CS2 NIC or Modem "PCB" it would be a big help. Cut it back at the ends so it will fit straight down into the slot and the use a pencil to run the outline of the case curve to model a max height CS2 card. Do the same with the PCI Riser to show the maximum for factor for a standard back RA "PCI riser." If anyone who could do this for me it would be a big help. Scanning the two cutouts along with a metric ruler would be the point, that way I've got something to mess around with. Another way of looking at it: EvilCapitalist, I wasn't sure about the labeling on your comparison pic. It seems like the front/back pics you posted are of the TAM riser? Can the board be extended to left or right? Will your 5500 riser fit within the Standard TAM Back? We've been ignoring the vacant cubic between PCI and CS2 connectors. My single slot 1U RA Riser's only about 19mm higher than the top of the connector and could be lowered to 5500 height if absolutely necessary. The PCI connector could be desoldered and replaced with Rows of headers for plugging in a "PCI daughtercard" to fit within the TAM's available PCI to CS2 cubic. Dunno about the TI PCI to PCIe bridge chip, but there's another that's compatible/transparent to the original PCI spec. intended for legacy equipment. If we can find a Mini-PCIe WiFi card with a chipset that's compatible with OS9 drivers we could be in business. It's nothing at all like something I could do, but it's looking more and more like the puzzle parts seem to be coming together. The really nice thing about using that cubic would be the possibility of setting the Mini-PCIe NIC up to fit in that cubic allows for the headers to fit on the available area between top of the mobo slot and the thruholes of the Fat Back PCI riser's connector. If the PCIe NIC/bridge is set up at the CS2 NIC Slot E1 location or the phantom Slot C1 location we'd be in TAM PCI Slot heaven. A customized Fat Back riser would have the usual Slot A1 connector and a connector for Slot B1 putting a PCI card in the cubic intended for the lowly 10bT CS2 NIC. Enough for the musings and back to the tangent at hand: Likely no time to test the LED kluge today, so info would be appreciated: oes anyone know if a logical high signal is adequate to power an LED so it's enough to be visible in a darkened room? If not I guess I can meter the resistor legs for high/low or do I need to find and re-learn how to use my ancient logic probe? Board's set up for doing that or adding a couple of header rows on the other end of the board for such testing or amplification of the logical high to LED driving level. edit: might as well ask up front in case I need one, anybody have a suggestion for a DIP IC amplifier that will drive four logical high inputs to LED power level outputs? Resistor and capacitor specs to drive such a circuit from an FDD Molex takeoff would be much appreciated. I have plenty of room on my snooper board for such shenanigans and almost no design experience for this. HELP!!!!!!!!!!

    trag, I think the third slot on your C600 riser may be C1. Took a couple of interesting screen shots: Full loadout on a Gazelle board shows PseudoSlot Video as F1, PCI cards in slots A1 and B1 with the CS2/NIC at slot E1. TattleTech has both Alchemy and Gazelle reporting Slot C1 as a possibility. Riser slot and CS2 were empty. That probably won't change with hardware state. Built my INT signal slot snooper kluge with the resistors . . . dunno, maybe it'll work? Maybe we'll see tomorrow.

    VST ZIP drive for 190/5300/3400/3500

    No 190 or 5300 available? Check contacts on every connector for grunge, maybe give 'em all an alcohol brushup? Try the module/adapter w/o a drive on it?

    VST ZIP drive for 190/5300/3400/3500

    Dunno, but if the drive's borked, snag the Dell P/N 653NH ZIP Module and treat yourself to a 250MB replacement drive. Snag one anyway as a test/backup drive. I can't believe it might be the Apple adapter card card gone bad? Highly recommended . . . the drive that is, not the seller, no connection there. Link's the first good deal to pop up in my search.
  11. Just that, My guess is that I won't need current limit resistors to show a signal held high at TTL levels. Next question: will a TTL high state current be enough to emit light from the diode?

    Ricoh chipset PCI to PCMCIA adapter card - possible?

    I'll have to buzz the 6500 riser I'm currently using. Then I'll map out the signals on the keyed 9 pin header setup on my complicated (more versatile?) riser. I'm guessing I can hack INTA-D high or low on the headers on the riser for the jumper wires. Mouser and others sell straight up three slot risers, so I'm wondering if the risers with nubbin card jumper setups are meant to allow Slot ID flexibility? I'm leery of trying to test the INT lines with the system hot. Might it be as simple as sticking four resistor/LED pairs into the female IDC header connections on the nubbin card cable, twist the ends together and insert one lead into the ground connection to make a remote Slot ID readout? At TTL hig/ low levels, do I even need the resistors? That explains the circuitry, jumpers/breadboard implementation would be the way to build it. I've got a single slot WrongAngle (Apple config left angle) riser that doesn't work, testing that one for Slot ID incompatibility will be interesting. Picture's worth a thousand words. These risers are for use in a 3U or 2U rack case, so they're RA to splay the cards out across Mac risers are WrongAngle for compact vertical expansion over the logic board. I've partially rebuilt my 6400/digitalSTARION 910 as a testbed. Mouser sells a straight up, no jumpers RA three slot riser analogous to Apple's (ostensibly passive) two slot LA riser. Sintech Electronics has a a fancier (my KISS compliant card seems better suited to the purpose) three slot riser that's interesting. edit: the speaker gave me startup chimes a few times, then stopped working entirely. Do TAM & company need recapping?

    Ricoh chipset PCI to PCMCIA adapter card - possible?

    Looks like it's about time to start another thread. I've started hacking away at increasing PCI Slot/expansion options for TAM/Gazelle. For now, I've started looking at 6360/Alchemy which is the basis for trag's three PCI slot + Comm Slot 2 Umax C600. No sense spinning wheels on Gazelle's incompatibility smeared 50MHz racetrack until something can be accomplished in the Alchemy architecture. My three slot riser doesn't work, other than the bottom slot tied directly to the Mobo's Slot $A1 Connector. The Riser has two jumper/nubbin cards and wiring to feed eight signals from each of two other slots on a system board to activate the upper two slots on the riser. The middle slot shouldn't be too hard to figure out from the 6400/6500 riser, it's a question of encoding the level triggered INT bits A-D to assign it to Slot $B1. That's exactly the same methodology and bit count for NuBus Slot assignments. Thankfully, the CS2 NIC shows up in ASP as a PCI Card in Slot $E1 and all necessary signals appear present on the Comm Slot 2 connector for hijacking to the third Riser Slot or in the case of the Interrupt coding bits that are probably built into the logic board, are easily implemented on the third slot of the riser itself. Adapting PCI to PCIe for using a Mini-Card WiFi NIC looks to be a less impractical endeavor than I'd figured. Mouser sells The TI XIO2001 PCI Bus Translation Bridge (bi-directional) for $6.41. trag, do you remember the ID of that third PCI Slot in your C600? That might make four PCI slots!
