    Mount SCSI2SD card in Windows

    CiderPress might be able to view/alter the contents without copying off the card. http://a2ciderpress.com/ It fully supports HFS partitions.

    Apple Ethernet NB - does it deliver?

    It'll give that A/ROSE extension in the system folder something to do https://en.wikipedia.org/wiki/A/ROSE The card was total overkill. Ironically hardware developers avoided driver development by just cloning Apple's "dumb" SONIC-based Ethernet card and using the built-in driver.
  3. For development purposes, the GSport emulator supports an Uthernet card in slot 3. Support has been tested with Marinetti under GS/OS and Contiki. It can also connect via MacIP (if you have a gateway available) using the built-in Appletalk emulation, but that has a bit of a learning curve to setup. AppleWin also supports the Uthernet in slot 3 if you are exclusively targeting 8-bit environments.

    A reminder that leaking caps kill more than Macs

    Eternal September offers free NNTP service for all the major Big 8 groups. Its handy to have around since Google Groups stinks for USENet newsgroups these days.

    Issues with Toshiba xm-3301b

    Hmm, this is a caddy loading drive? Its likely suffering from bad caps as the Sony drives Apple used suffer from the same problems.

    Issues with Toshiba xm-3301b

    These drives have notoriously fragile loading trays. User CelGen can tell you ALL about them. http://www.vcfed.org/forum/showthread.php?40455-Toshiba-SCSI-CD-ROM-Drives The last one of these drives I had (IDE version, but same tray loader), landed up smashed on a concrete floor in a fit of rage because of that stupid tray sticking.
  7. The drive is in a Smart and Friendly branded case (someone swapped the original drive out), but its the same model. The drive was released in 1999 or so, I don't recall having any problems getting it to work with the CD Sunrise driver or the "universal" Apple CD driver. The only documentation that came with the Plextor PX-R820T drive is the jumper settings, which should be on the label of the drive itself if you open up the case. I would check the obvious, like is the SCSI ID set correctly, and is the drive terminated if its the last device on the SCSI chain. Lock ups could be SCSI problems, not a driver problem. Don't worry about flashing the firmware, the Imation and Plextor firmware is identical outside of the ID string.
  8. Is it this drive? https://www.cnet.com/products/imation-super-recorder-8x20-cd-r-drive-scsi-external/ If so, its really a Plextor Plexwriter 8/20X with Imation branding. I have the exact drive (flashed to ID as a Plextor), and it works fine connected to Mac SCSI ports. I wouldn't bother attempting to burn CDs with that drive on a 68k machine though. It lacks buffer under run protection and will result in a few coasters.

    Printer and Scanner for Performa 6116

    Apple's inkjet printers were almost all Canon Bubblejets except for the last few that were clearly HP Deskjet re-brands. HP also sold their "DeskWriter" inkjet line specifically for Macintosh. In terms of lasers, they were almost all entirely Canon engine printers that had HP Laserjet equivalents. HP also sold "M" variants of their LaserJets that came standard with PostScript and Localtalk built in. In terms of Apple scanners, they too were mostly Canons. I know my Color OneScanner 600/27 was a Canon Canoscan 300 in a different case. It even IDed itself as a Canon to the SCSI bus and worked fine with the Canon drivers in Windows. Even if you don't find an Apple one, most scanners from the time period have Mac drivers. UMAX comes to mind here.
  10. Just keep in mind that the Lisa clock can't be set beyond 1995. Even Apple knew it wasn't going to be on the market that long!

    Source for IWM Chips?

    The source to the ROM on the original CFFA cards is available online as a good example. Regarding ROMs, usually the 2K sized ROMs map the first 256 bytes to $Cx00-CxFF, and the whole 2K (including the same first 256 bytes) to $C800. The upper 2k on 4k ROMs is usually bank switched by writing to an I/O port on the card.

    jt's Random Questions Thread

    The cover for the modem on the personality card is just a knock out plate. Just pop it out and install the modem. I have a 56k CS II Global Village modem from a 6500 I stripped years ago. It appears to be the same unit that went into the beige G3s. I never bothered to try installing it, because I wanted to keep the knockout plate in place.

    Source for IWM Chips?

    There are pictures floating around of an IWM based Disk II controller that Apple prototyped. Don't know if they actually sold though. The rumor as to why was cost of production. Ironic considering the IWM design was supposed to be cheaper to make than the discrete logic. Photos here: http://www.retro.co.za/ccc/apple2/disks-and-controllers/ In theory, one should be able to modify a bog standard Disk II card, replacing the boot PROM with the Liron card's firmware (with ROM decoder logic), and land up with an equivalent card. Disk II cards and the parts that they are made of are very easy to source, so its worth a shot going down that route.

    Mac Plus external Video Mod: TTL to VGA?

    They convert the scan rate. The GBS-82xx converters tend to have poor video quality and have a nasty habit of needlessly applying de-interlacing to progressive scan signals. I wouldn't be surprised if it worked with a Mac's video output though, just don't expect pixel perfect quality.

    Odd Power Macintosh 7xxx? Setup

    Not quite, the 8600 and 9600 boards support the faster 604ev CPU cards, the earlier boards don't. You won't get any life out of a x500 machines if you swap in a 604ev card.

    Mac Plus external Video Mod: TTL to VGA?

    NEC's older projectors tended to work with 15khz RGB input. If that model has been tested for 15khz compatibility, its likely it'll sync with a 22.15khz signal too. Many arcade PCBs and the Sharp X68000 computer outputted 24khz (also close to EGA 640x350 mode), so its worth checking compatibility lists for those too. Many video scalers will support it as well (not that Startech things, you need something that handles RGB input).

    Mac Plus external Video Mod: TTL to VGA?

    Looks like the complicated circuit in the Homemade Mac article is just combining the sync signals into the video signal and altering the timing to make it close to NTSC spec, something you don't have to do with a proper monitor. The monitor pictured is not the AppleColor RGB typically found with the IIgs, but a paper white monochrome version that was available but rarely purchased. It has a composite jack on the back of it like Apple's earlier green screens.

    Mac Plus external Video Mod: TTL to VGA?

    The horizontal scan rate is lower then what a VGA monitor would normally take (22.25khz vs. 31.5khz for VGA), so take that into consideration first. You may not even need the TTL adapter mentioned in the book if the Mac's video output is similar to analog RGB video levels (1Vpp). Looks like Larry is assuming one is using a CGA or EGA monitor that was common at the time and required TTL input.

    SCSI CD Drive 68 pin -> 50 for Macintosh use?

    Must been an OEM deal as the only retail drive Plextor sold with wide SCSI was a 40X drive. Make sure the 68 to 50 pin adapter you have properly terminates the upper byte of the data lines, otherwise it likely will not work. It might not be a problem though as this drive doesn't appear to be a real "wide" SCSI device since it only allows ID setting from 0-7.

    Black VARTA PRAM battery

    The black Varta in my IIgs is of similar age and still keeping time. No leaks that I can see.

    Is the 660AV case the same as the 6100?

    My 6100 uses a 610 caddy load CD-ROM face plate.

    Beige G3, IDE and Apple's ridiculous implememtations . . .

    One could say the 630 platform was so good, it was worthy of being used with a PPC 603e..... [ ] As for the DB-25 SCSI port, even Adaptec used it on a few of their ISA cards and it was the defacto standard on Apple II SCSI cards (both Apple and 3rd party).
  23. Does the Macintosh 128k even have enough RAM to run any sort of LaserWriter driver? By default it requires LocalTalk, which might not run on a 128k.

    Beige G3, IDE and Apple's ridiculous implememtations . . .

    To be fair, most PC motherboards until the beige G3's time period still had the key pin intact. Plenty of cables did not have pin 20 blocked off either, if it did, a firm press when installing would punch out the keyed hole. I don't think Apple intended the SCSI to be used as the primary storage interface on the beige G3, it was kept for backwards compatibility and general peripheral usage, which 5MB/sec was usually fine for. What was ridiculous was only having 3 PCI slots and 3 DIMM slots!
  25. A co-processor for what exactly? The same CPU was found in Xante Postscript printers in 1992, using standard 72-pin SIMMs to handle Postscript duties (a very common application for the AMD 29000 series). According to InfoWorld, its just a general purpose RISC CPU accelerator card. https://books.google.com/books?id=lzsEAAAAMBAJ&lpg=PA37&ots=YNfm8A4P_v&dq=YARC%20Macintosh&pg=PA37#v=onepage&q=YARC%20Macintosh&f=false They did Postscript RIPs too! http://www.creativemac.com/HTM/News/10_00/yarcepsonrip.htm https://web-beta.archive.org/web/19970414164343/www.yarc.com
