>I trust Greg told you that I would be coming to you for info about the >A4000 while he's away. No, he forgot, but it doesn't surprise me, I knew this was a hot item. >11) CPU: If an 020/030, there will either be a surface-mounted FPU and a > footprint (no socket) for a replacement FPU, correct? That's correct, there will be the PCB holes for a PGA socket or FPU, but no socket supplied. >2) Will the boards with factory FPU have a socket for the FPU osc., or > just a footprint also? I'm not certain what's planned for the FPU. My guess is that it too is just left as a footprint, no socket. >3) Will the 040 board not have sockets or footprints for FPU or osc.? The '040 board has no FPU socket or osc. >4) On the 020/030 boards, will there be any jumpers for user options > other than the external FPU osc.? Any other sockets or connectors? There are several other jumpers. Here's the list (the names are from the schematic, I think some of them could be a little more descriptive). J100 "FPU SELECT" Selects between the PLCC and PGA version of the FPU. 1-2 PLCC FPU is selected. 2-3 PGA FPU is selected. J101 "FPU CLOCK SOURCE" Selects between the 25MHz motherboard clock and the FPU osc. 1-2 FPU osc. is selected. 2-3 Motherboard clock is selected. J103 "MAP ENABLE" This controls the RAM->ROM mapping option of the board. 1-2 Mapping disabled. 2-3 Mapping enabled. J201 "020 SELECT" This enables or disables the 68020. 1-2 68020 disabled. 2-3 68020 enabled. J202 "030 SELECT" This enables or disables the 68030. 1-2 68030 enabled. 2-3 68030 disabled. J203 "020/030 SELECT" This switches the bus grant signal for '020 or '030 operation. 1-2 68030 operation selected. 2-3 68020 operation selected. I imagine that the MAP ENABLE jumper would be of interest to users. Both FPU SELECT and CLOCK SOURCE SELECT would need to be changed is a user added a faster FPU and clock. The '020 vs. '030 select lines would allow a user with an '020 board to have the '020 disables and a surface mount '030 installed and enabled. I don't know that we plan to have any '020 boards actually made, or that installing a 128 pin 0.025"-grid surface mount part is the kind of thing most users taks on, but those are the actual details of this board. >5) Will there be any user options at all, or different models (cache, > normal/EC, etc.) for the 040 boards? I've heard talk about 1MB/4MB > versions of the card; this does not jive with what I know. There is no memory of any kind on the '040 board at present. It's certainly possible to offer 68EC040, 68LC040, or regular 68040 versions of the board, since all three 68040 variations have the same pin configuration. As far as I know, the only one definitely planned is the 68EC040 version, though if UNIX gets a 68040 upgrade (currently in some kind of progress), it would make logical if not marketing sense to offer at least an LC version. But I don't know of any plans beyond the EC version. The 68040 will be socketed, so this is certainly something users might upgrade on their own. In general, there may be additional CPU board options in the future. The ones I know they're definitely planning, as of today or so, are the '030 and the 'EC040 version. >6) I need diagrams (board silkscreens would be fine) for the CPU boards, > and lists of all relevant jumpers, socket info, etc. You have the jumper list above for the 20/30 board. The '040 board has only two: J400 "MAP ENABLE" (same function as J103 on the other board). This controls the RAM->ROM mapping option of the board. 1-2 Mapping enabled. 2-3 Mapping disabled. 3-4 Test only. J100 "EMULATOR" This jumper controls the source of the MMU disable input of the 68040. 1-2 Test only. 2-3 MMU disabled. 3-4 MMU enabled. I'll get Fish to print out some silkscreens for you. >7) Power cables: Greg said there will be two power cables for the rear > internal drives (is there a standard name for this connector form > factor?) and two floppy connectors for the front. The connectors are generally just called "Hard Disk" or "Floppy" power cables. >He thought there might be one or two other HD-style power connectors for front- >mounted devices. Are there? There are two hard disk power connector for the rear, two for the front. >8) Keylock:: Is this a two or three position lock? Two. >What are the functions of each position? Does the lock position lock: 1) >just regular kybd access; 2) kybd & mouse access; 3) kybd & mouse access, >including Ctrl-A-A; 4) all kybd & mouse access, and power-down; 5) none of >the above? The lock position locks out all keyboard and mouse activity. It does not lock out the analog joystick or mouse button functions, nor does it lock out power down. >What indicates the keylock positions? Little padlock glyphs? I think they use padlocks, but I'll have to check on it (the only case we seem to have is out in the FCC shack). >9) Chip RAM: Can you use static column mode modules here? Does it > increase performance like with Fast RAM? Static-Column modules can be used, and they do increase Fast RAM performance, though not Chip RAM performance. The downside is that Static-Column modules are non-standard, while the Fast RAM modules are standard. >10) I need the pinouts for: 1) PCB audio connector; PCB Audio Connector: PIN Signal 1 Left Audio In 2 Audio Ground 3 Right Audio In >2) new video slot pins. 24-Bit Video Slot/Connector A PIN Name Signal 1 RBG16 Red bit 0 2 RBG17 Red bit 1 3 LINELF Audio line out left 4 LINERT Audio line out right 5 C28O Pixel-synchronous clock 6,8 +5V Main power 7 ARED Analog red 9 GND Digital ground 10 +12V High voltage power 11 AGREEN Analog green 12,13 GND Digital ground 14 /CSYNC Composite sync 15 ABLUE Analog blue 16 /XCLKEN Genlock clock enable 17 GND Digital ground 18 BURST Video burst 19 /C4 3.55/3.58MHz clock 20,21 GND Digital ground 22 /HSYNC Horizontal sync 23 RGB4 Blue bit 4 24 GND Digital ground 25 RBG7 Blue bit 7 26 /VSYNC Vertical sync 27 RGB15 Green bit 7 28 BLANK Video blank 29 RGB23 Red bit 7 30 PIXELSW Genlock overlay 31 -5V Negative supply 32 GND Digital ground 33 XCLK Genlock clock 34 /C1 3.55/3.58MHz clock 35 +5V Main power 36 PSTROBE Printer port handshake 24-Bit Video Slot/Connector B 1 GND Digital ground 2 RGB20 Red bit 4 3 RGB21 Red bit 5 4 RGB22 Red bit 6 5 GND Digital ground 6 RGB12 Green bit 4 7 RGB13 Green bit 5 8 RGB14 Green bit 6 9 GND Digital ground 10 RGB5 Blue bit 5 11 RGB6 Blue bit 6 12 GND Digital ground 13 SOG Sync-on-green indicator 14 TBASE 50/60Hz software clock timebase 15 CDAC 7.09/7.16MHz clock 16 PPOUT Printer port paper-out 17 /C3 3.55/3.58MHz clock 18 PBUSY Printer port busy 19 /LPEN Light pen input 20 /PACK Printer port acknowledge handshake 21 PSEL Printer port select 22 GND Digital ground 23 PPD0 Printer port data bit 0 24 PPD1 Printer port data bit 1 25 PPD2 Printer port data bit 2 26 PPD3 Printer port data bit 3 27 PPD4 Printer port data bit 4 28 PPD5 Printer port data bit 5 29 PPD6 Printer port data bit 6 30 PPD7 Printer port data bit 7 31 /LED LED (audio filter bypass) setting 32 GND Digital ground 33 RAWLF Raw (unfiltered) audio left 34,36 AGND Audio ground 35 RAWRT Raw (unfiltered) audio right 37,38 N/C Reserved 39,40 GND Digital ground 41,42 N/C Reserved 43,44 GND Digital ground 45 RGB18 Red bit 2 46 RGB19 Red bit 3 47 RGB8 Green bit 0 48 RGB9 Green bit 1 49 RGB10 Green bit 2 50 RGB11 Green bit 3 51 RGB0 Blue bit 0 52 RGB1 Blue bit 1 53 RGB2 Blue bit 2 54 RGB3 Blue bit 3 >Also a list of any jumpers on the motherboard that are potentially useful to >a user. J100 "CLK90 SOURCE" This jumper selects the source of the 90 degree clock. 1-2 Sourced by the motherboard. 2-3 Sourced by the processor card. J104 "CPU CLOCK SOURCE" This jumper selects the source of the main system clock. 1-2 Sourced by the motherboard. 2-3 Sourced by the processor card. J151 "ROM SPEED" This selects the speed of the ROM. 1-2 200ns ROM. 2-3 160ns ROM. J211-J213 should never be changed by users! Improper operation and possible damage to the Alice chip could result. J351 "DF1: enable" This enables the ID code for a standard 3.5" floppy at DF1: 1-2 DF1: ID code generated. OFF No DF1: code generated. J500 "SYNC ON GREEN" This controls the sync on green support needed by some monitors. 1-2 Sync on green disabled. 2-3 Sync on green enabled. J501-J503 should never be changed by users! Changing them will result in improper display generation by Lisa. Some or all of these may disappear in future revisions. J850 "DSACK ENABLE" This selects the kind of memory termination based on CPU. 1-2 System is set up for 68020. OFF System is set up for 68030/68040. J852 "RAM SIZE" This selects the size of memory module that can be used on the Fast RAM bus. 1-2 4MB density modules are supported. 2-3 1MB density modules are supported. J975 "OPTIONS" Various yet-to-be-defined system options may one day be set by these jumpers. Right now they aren't used by the OS and should be left alone. >11) Does the fact that DF0: connector is the one without the twist have > any effect on how the user must set jumpers in a multi-drive setup? I think they jumper DF0: differently now, so DF1: should be the same as its always been. The idea behind the twist has always been to let DF0: and DF1: have the same on-floppy configuration. That always struck me as a bit odd, but of course we were always using a variety of different make floppies for DF0:, so the jumpering could have been confusing. Only Chinon makes the HD floppy which (last I head, at least) will always be used for DF0:, so there's no longer any variations. > Are there still two floppy jumpers to consider, the one on the drive > and the one on the motherboard? Yes. The motherboard jumper is J351. Its only necessary to connect this if the second floppy is a standard 3.5" drive. If its the C= high density kind, J351 need not be changed. >12) How does the IDE device unit # (or whatever IDE uses) get set when > you have two IDE devices? The motherboard generates selects for two IDE units. You change a jumper on the IDE drive to set it up for unit 0 or unit 1, kind of like the SCSI unit setting, only of course there are only two possible units. That's about all I know about IDE -- if you have any detailed questions, you should ask Randell Jesup, the resident hard disk expert ("jesup" on cbmvax). >Are there any caveats for people using *both* IDE and SCSI devices in the >system? That may depend on which SCSI card they use. The A4000 software calls the IDE device driver "scsi.device". I believe all the C= device drivers, like A2091, know how to coexist with one-another in multiple card setups. In most cases, the user doesn't need to worry much about it, the HDToolBox program should make it obvious which drives are connected to which board. If you're using 3rd party hardware, they call their device driver something else (eg, "gvpscsi.device", "hardframe.device", etc.) and there's no conflict, though the user would probably have to use the 3rd party software to configure the 3rd party device, C='s HDToolBox for the IDE. >I won't appreciate it if you could respond ASAP. You won't? Should I delay this for a few days :-)... -Dave
