    Perifractic wants to buy Commodore

    Let's keep it civil. If you really want to get into a debate, try it using video chat - that's worth hours of entertainment, and at this point you could probably sell tickets and turn a profit. Or better yet, agree to disagree and move on.

    Mount DOS compressed volume (e.g. DoubleDisk) on Linux

    If you are going to get it running under an emulator and the emulator supports networking, then try mTCP NetDrive. mTCP NetDrive will let you add a drive letter to the emulated machine. Then you can use xcopy recursively to transfer the contents of your compressed drive to the network drive...

    IRC chat: #vc on slashnet.org

    It was quiet this afternoon, but it is certainly not dead. (I was just testing an IBM Portable PC with it.)

    PartUtil: Dual boot DOS without a boot manager

    This is a typical developer story ... Back in 2012 I got the first jrIDE running on my machine, and I was thrilled to have a bootable hard drive interface for it. I wanted to use both DOS 3.3 and DOS 5 and I figured I would have logical drives so that my common programs and utilities would be...

    Drop-in 8088 CPU Emulator for the IBM PC - MCL86+

    My apologies ... wrong thread. I get too excited when I see the MCL prefix. ;-0

    Drop-in 8088 CPU Emulator for the IBM PC - MCL86+

    Bravo! I'm looking forward to getting mine updated. Have you tried MS Flight Simulator 2.1 on it? That is where I originally noticed some glitches in the screen rendering. If it passed Glorious Cow's test suite then flight simulator is probably happy too. Unrelated: I've been following his...

    Call for ideas/fixes for the next mTCP version

    No problem at all .. it would have been more accurate for me to say MSKermit just wasn't on my radar because I don't use it. Parsing the mTCP config file and generating a *good* WATTCP config file or the MSKermit environment variables should not be difficult, and I agree, there should at least...

    PartUtil: Dual boot DOS without a boot manager

    The short story: a small (20KB or less) partition editor that makes it easier to select and boot DOS partitions without having drive letters shifting around. https://www.brutman.com/PartUtil/PartUtil.html The longer story ... I've been running DOS 3.3 and DOS 5.0 on a PCjr for over 10 years...

    Call for ideas/fixes for the next mTCP version

    Hi, it sounds like you have some issues related to your choice of hardware. While many people can use a shim to convert NDIS or ODI to the packet driver specification, the most reliable thing to do is to find the native packet driver for your Ethernet hardware and use that. (If it even exists...

    Perifractic wants to buy Commodore

    Wow .. I never knew about that market. So I went to their web site and sure enough, they have typewriters with clear cases approved for use in various prison systems. They even sell replacement ribbons with clear cases. It makes me think twice about all of those clear Amiga, C64 and...

    Perifractic wants to buy Commodore

    I'm not familiar with perifractic. I just watched both videos in their entirety (1 hour) and that was just painful. Not my style ... Keep in mind that they have an agreement to purchase in place. No money has traded hands yet. That's a big hurdle to clear. The vision about saving us from...

    "opcode trap" on old AT clone, any advice?

    Another consideration - the RTC has the ability to generate interrupts. If that happens too early (before the interrupt vector is ready) then the machine will jump to what looks like garbage and execute it. I don't think that feature is used often, but it reiterates the need to ensure that the...

    "opcode trap" on old AT clone, any advice?

    The short story is that it's basically an illegal instruction. Did it try to boot from the hard drive or the floppy drive before that happened? It is important to know if the bad code is in the BIOS (unlikely) in the boot code that it tried to load and run.

    Abort, Retry, Ignore errors with XT-IDE and CF Cards

    I've not tried the StarTech SATA-IDE bridge on an older "native" IDE port. Just jrIDE and newer ports. I'll look into SD adapters again. How unlucky can I get? Thinking more broadly, I'm beginning to see a need for a debug version of the XT-IDE BIOS if I'm going to get anywhere. Something...

    Abort, Retry, Ignore errors with XT-IDE and CF Cards

    I tried two different PATA to SD adapters on very different systems and I couldn't get either of them to work. One system was slow with a jrIDE, and one was reasonably fast with a real motherboard IDE interface. After a few hours and a few different combinations, I just gave up. Do you have a...
