    I wonder if the cartridge software disk is the z80util and diskutil Bob patched so that you could use SCSI drives via the Bernoulli card? Per usenet Bob sold that for $1600 a pop and it would only work with Xenix 3.1.x.

    Everything seems to line up on the label except the "gregutil" unless gregutil = diskutil.

    I cant wait to see what you find.

    Oh, man, I recall reading about those patches. Can you imagine if we could run SCSI drives in XENIX??

    If the cartridge software disk is Bob's Bernoulli SCSI patches then the memswap disk could very well be his drivers that allowed you to swap to RAM instead of disk. I've read posts where on a non-MMU'd 6K you could have 1MB RAM and up to 7MB swap with that driver.

    Man, I'd have loved to have gotten my hands on the 6K these disks belonged to!

    I have a couple of 6000's with 2 meg memory cards. They use 256k SIPPS soldered in place. I also have external hard drives with the associated Xenix install on them, but they were not kept together (weren't when I picked them up) so I don't know where the kernal is.

    Snapp's SCSI patches still required Xenix to be installed on an MFM drive. It allowed for SCSI secondaries. I remember several long conversations about them, but we never needed more than the 280 MB that was supported using MFM. As it was, we were experiencing very slow response with 6 users and 1 meg of memory. That was running mail merge documents integrating filePro and Scripsit 16.

    Very cool. You’ve got to have an 8Mhz MMU somewhere in the dungeon!

    Thanks to MikeModified these disks are now in the workshop getting ready for imaging and archiving.

    As suspected, we now have a copy of Bob Snapp's MEMSWAP.

    The power.supply document is an interesting read. Bob certainly writes in a humorous personal style.

    Bob was a real character. Used to love talking to him.

    I have a couple of Snapp disks. I have (somewhere) all of the terminal entries he and D. Lee Penn created for the WY-50 terminals.
    I had an mfm cartridge drive he modified to work with the Tandy Xenix too.

    The disk marked "Xenix 3.1 Correction to 3.1.1" is the official Tandy 700-3035 XENIX Upgrade for 3.1.0 to 3.1.1 which we were missing.

    Amazing these were found after all this time. I loved reading power.supply and switches.doc!

    Big thanks to Mike and Pete for rescuing them. Hopefully somebody uncovers an MUSIE archive some day.
