This file describes the contents of the TWAINx.xxx files available in this LIB. The photos were taken on January 6, 1996, at the home of Jim Wifall, Apple II Librarian for the Applequerque Computer Club in Albuquerque, New Mexico, during our monthly Apple II Library Meeting. On display was one of the prototype "next generation" Apple IIgs machines whose existence was recently discovered and exposed to the world. Often referred to as the "ROM 4 IIgs," it actually boots up identifying itself as a ROM 3 unit, but it is a different machine whatever its ROM version. The machine was code-named "Mark Twain" while under development at Apple, and I refer to it as such here. I scanned these photos at work on a 1200 dpi grayscale Xerox flatbed scanner attached to a Macintosh (sorry!), and used Adobe Photoshop to enhance them somewhat (particularly with respect to bad lighting conditions). They were exported as GIFs and moved to the Apple IIgs in that form, converted to Apple IIgs SHR format by Jason Harper's SuperConvert, then uploaded here. -Joe Walters Albuquerque, NM ***** The first set of photos are stored in Apple-preferred format (IIgs super hi- res) and are in 16-color grayscale: ***** ---------------------------------------------------------------------------------- Note update by Charles Turley - 5/14/97 - 10:02 AM (PDT) I've converted them back to GIF format and made them available to the public from our public A2 ftp site - so that everybody with any Apple Computer models and ftp or WWW access can now view them as a GIF and/or download them for there own use. The original .BXY files the SHR pictures and this text file came from will be made available later on this evening within the GS WorldView GENIE.GRAB.BAG folder. The outlines of each picture below refering to them as SHR is noted for each as the conversions back to GIF format retain the same file name, excluding the .SHR noted. ---------------------------------------------------------------------------------- ***** TwainA.SHR: Mike Westerfield looks on as Jim Pittman uses the Mark Twain machine. The monitor to the left is attached to a stock ROM 3 IIgs we were using for comparison tests. TwianB.SHR: Jim Pittman at the Mark Twain. That's Jim's 170MB Focus Hard Card in the fifth Slot (Slot 6). Sorry my camera put part of its automatic date stamp on the card! It's that dang newfangled technology, you know. TwainC.SHR: Mike Westerfield at the Mark Twain, contemplating What Might Have Been. Jim Wifall's ROM 3 IIgs is visible in the background, and against the wall is the framed photo shown in TwainN.SHR. TwainD.SHR: Sorry, this one's a little blurred (lighting conditions weren't optimal, and I didn't have a flash unit with me). This is looking across the open Mark Twain motherboard; the front of the GS unit & keyboard is to your left in this shot. At the top is the power supply (to your right) and the floppy/hard disk complex (to your left). Note the circuit board attached to the back of the hard drive. Note also the cable from the power supply to the motherboard, visible between the power supply and the circuit board. Just below that circuit board, you can see the rectangular connector (blue plastic) attached to the motherboard that we suspect is some kind of SCSI port. At left, by the front of the floppy drive, you can see the two wires that connect its eject button to the motherboard. It attaches to a little two-prong connector there, and there is a second identical connector right next to it. At the bottom of the photo, near the left edge, you can see one of the chips attached by wires to the motherboard. TwainE.SHR: Looking into the front of the Mark Twain unit with the cover off. On the left, you can see the floppy drive (top) and the 40MB hard disk (bottom). The plate on the right of this complex holds the eject button for the floppy (the button itself is between the two screws; the outer plastic cover has a different plastic button that is really just an extension that is used to actuate this button). On the right side of the motherboard at the front, you can see the two SIMM slots. It's pretty fuzzy in this shot, but at the extreme back right side of the motherboard, you can see a tall black rectangular object. The bottom half of it is the same as on a stock IIgs, where you plug in external speakers. The top half of it attaches to what we believe is a microphone port. TwainF.SHR: The Mark Twain unit with cover on. Ignore the sticker on top; it's a mover's sticker and not part of the unit. Note that the cover is a plain, unmodified IIgs cover that was apparently grabbed off the assembly line before the name "Apple IIgs" was silkscreened on. The opening for the floppy disk was then cut into the front of the cover (as was the opening for the eject button--notice it comes with the standard paper clip port!). For this unit, the little green plastic thing that covers the "Power On light" hole is missing; you're looking through to the green LED on the motherboard. TwainG.SHR: Pullback of the same shot in TwainF, showing the monitor & Finder. Note the internal 40MB hard disk is partitioned into two volumes! That's Mike Westerfield's hand, by the way. He's trying to reset the mouse from its "maximum slow" setting to something usable. TwainH.SHR: The whole unit, opened up. You can see the SIMM slots near the bottom right of the motherboard. Next to the SIMM slots on the left is the ROM 3-type battery holder. Behind the SIMM slots is a small cylindrical object--that's the sound transducer thing. You can see the five slots (left to right: 1, 2, 3, 4 and 6). The white rectangle between slots 3 and 4 is the old II+ style game connector. Note that the metal cover normally inside the back panel is absent. TwainI.SHR: Close-up of the visible motherboard (we haven't yet explored beneath the power supply/floppy drive complex). Keyboard is to the left. The two SIMM slots are at the bottom left of the picture, and the battery is just above the SIMM slots (note someone has inked in a "+" symbol at the positive end of the battery on the motherboard--there is no printed mark there on the board). The sound transducer is visible to the right of the SIMM slots. Above and to the right of the battery you can see three chips connected by wires. The five slots are visible to the right (1 is on top, 6 is on bottom), and just below slot 6 are some more wire connections. At the extreme bottom right is the black object (also wired to the board) that connects to the headphone and (presumably) microphone jacks. TwainJ.SHR: Extreme close-up from TwainI showing the SIMM slots, battery (with inked-on "+" symbol), sound transducer (bottom right), and some wire- attached chips & resistors. TwainK.SHR: Another extreme close-up from TwainI, this time focusing on the bottom right portion of the motherboard. At bottom right is the tall black plastic object consisting of the plug-in connectors for the headphones (bottom) and (we think) microphone (top). Note it's attached to the motherboard by wires. Just above it are the two serial ports, same as on a stock ROM 3 IIgs. At the top left is a little chip that is attached upside-down (really--it looks like a dead bug with its legs in the air!) and you can see the wires leading from its legs to a nearby socket. TwainL.SHR: Mark Twain's back panel. It's a plain IIgs back panel, with two notable mods: (1) on the right side, two new holes were cut into it to accommodate the power cord and on/off switch for the new power supply; note parts of the old cutouts are still visible. (2) On the left, just above the headphone jack, is a new jack that we are guessing is intended for a microphone. Note that the headphone icon is present under the headphone jack, but they didn't bother to add an icon for the other jack when they cut it in. In adition to the mods to the plastic case, note that the shape of the power supply is such that it covers one of the openings in the back panel (just above the video plug). TwainM.SHR: The ID plate on the bottom of the Mark Twain unit. Again, it's a stock ROM 3 case--they just attached a printed sticker on top of the old ID data. Our best guess: EVT=Electronic Video Terminal. Note the screw stuck just above the UL symbol--it's one of two holding the hard disk/floppy drive/power supply complex attached. TwainN.SHR: Detail from the framed photograph that was on display along with the Mark Twain machine. I've probably taken worse pictures in my life, but I don't know when. I was shooting thru a reflective glass frame in bad lighting, but even so, this is gross! The original looked nice, really! Anyway, compare this shot to the top half of the cover picture of the last issue of the "Apple II Guide" published by Apple. In the published version, on the right side, below the Mac LC picture, there is a book interestingly titled "Mark Twain." This is a previous version, and you can see in the book's place that there is a shot of this machine, right down to the internal floppy drive and no silk-screened name (well, you could see it better if I had gotten a better picture). Below the picture in this frame, the owner had placed a printed quote from Tennyson: "Better to have loved and lost than never to have loved at all." Appropriate. ***** These photos are in much higher resolution, and are provided for the convenience of those who have access to machines that can handle larger GIF files and who want to see some of the details better. They're about 1MB each in size, and are stored at 300dpi. They were scanned at 1200dpi, but files in the 15 to 20MB range seemed a bit excessive for this Forum! ***** TwainHR1.GIF: (1370x809x256 grayscale GIF) Hi-res version of TwainE.SHR, looking into the front of the unit with the cover off. Details visible on the floppy drive/hard disk complex. TwainHR2.GIF: (1107x933x256 grayscale GIF) Hi-res version of TwainH.SHR, showing the motherboard at an angle. Good shot of the SIMM slots and the floppy/hard disk complex with the apparent SCSI port (?) underneath, as well as some of the wired connections. TwainHR3.GIF: (1519x756x256 grayscale GIF) Hi-res version of TwainI.SHR, showing the entire visible motherboard from overhead. Clear view of the SIMM slots, the sound transducer (and a familiar plug next to it, much like the one used to hook to the Ensoniq chip in production IIgs models), slots, and various other details. Wire attachments visible near the bottom right, just left of center, and in the upper left, where the floppy drive eject button is connected to the motherboard. -------------------------------------------------------------------------------- It may be of interest to note,that a lengthy and detailed text file concerning the GS+ (Mark Twain - aka - ROM 04) is also included within the 1WSW folder. The one thing not mention in either this or the other text file is that - the Mark Twain could only handle a total of 4MB of RAM. To avoid public confusion concerning this Mark Twain prototype computer it should be made clear that it has no ROM 04. The ROM is identical in all respects to the IIgs ROM 03. Charles T.
