    BA11-K (or equivalent) Unibus Expansion Chassis

    I'd like to add a Unibus expansion chassis to my VAX-11/730. I might try adapting an extra stripped PDP-11/44 chassis from my project pile for that, but if I could find a proper BA11-K (or equivalent) box with Unibus backplane(s), that would be swell. I think one might fit in the space under the...

    Model 2 restoration

    Hmm, now I'm imagining converting my 6000 project to a 6000FreHD, with a hard drive emulation hidden behind a trim panel in the second floppy drive bay. Might as well hide floppy drive emulation in there, too, with a switch to select either the real floppy drive or an emulated one for floppy...

    Kaypro 4/83 Extra PIO Ports

    Poking around in the schematic diagram of my Kaypro 4/83, I see that there are two 3881 PIO chips, each with one 8-bit port used and the other 8-bit port routed to test/expansion points. Are there any historical accounts of Kaypro, third-party manufacturers, or end users making interesting use...

    Debugging Farallon Ethermac NuBus Card in Macintosh IIci

    I have a Macintosh IIci, running System 7.1. My dad got me a Farallon Ethermac NuBus NSC PN590A for Christmas, and I'm having trouble getting it working. He had the foresight to pick out one that came with a driver diskette. It didn't come with a manual, so I guessed that plugging it into an...

    Boot Disks for 512k Mac

    I just won a Goodwill auction for a 512k Mac system. Yay! No floppy disks are pictured, so I assume that I will need to procure or create boot disks for it after I clean it up (and if necessary, fix it). I'm looking forward to receiving it! This one looks like it was never upgraded with 800k...

    Is this an S-100 chassis?

    A friend is offering me this chassis with a couple of 8" floppy drives in it. I would want it for the drives in any case, but maybe I can find a use for the whole thing. Does this card cage look like an S-100 bus to y'all? I won't have the unit in my hot little hands for a couple weeks or so...

    FreHD Serial Port Use

    Is anybody using the serial port that is present on the FreHD? If so, how? I have the impression that it is a vestigial debugging feature, and I wonder whether there is any means to access it from the TRS-80.

    Expansion Bus Peripherals for Models III/4/4P?

    I'm curious about what vintage peripherals were made for the models III, 4 and 4P that plugged into the bus expansion connector. There were the hard drives, of course, and also the Orchestra 90 if I'm not mistaken. Were there any others, whether from Radio Shack or third parties?

    WTB: Data General 6030 Dual Floppy Drive, plus Other Nova Stuff

    I'd like to add a number 6030 dual 8" floppy drive to my Nova 3/12. I already have a 6045 hard drive and its controller (both of which I'm still debugging), and the documentation I have states that the 6030 can be mixed with 6045 drives on the same bus. So, I'd like to find a 6030 drive unit in...

    Data General Nova 3: 6045 Drive Debugging Progress

    This forum needs more Nova chatter! After a long hiatus, I've given my Nova 3/12 some more brain bandwidth. It consists of a Nova 3/12 and a 6045 hard drive. The drive has one 5M fixed platter, and one 5M removable pack. A couple of packs came with the system. I have not been able to boot the...
