  1. WTB: TI Silent 700 printhead and keyboard or keyswitches

    I need a new printhead for my Silent 700 terminal (745 model). It has several burned out pixels.

    Also, the keyboard has four bad Hall-effect switches. They are difficult to remove individually...

    The other terminal had the nylon thumbwheel (on the printhead pressure adjustment) split and fall off. So I fixed that by drilling the knob and the shaft and pinning them together. Installed the...

    I bowed to the inevitability of "collectible" prices, and bought one for $200 shipped. I have 2716's and 2102A's in the parts bin so I can do the lower case mod.

    Does anyone know of an available...

    Yeah, I don't understand the keyboard freaks at all... must be a "gamer thing".

    Although I am looking for four Hall-effect key switches for my other Silent 700 though... or a 100% working...

    Yep, I used them in the late 70's too!
    I'll bet the guy with the $165 "deal" got a busted one. Although (as an '80's EE who made my living designing and testing 8-bit embedded micros) I think I can...

    Sure, there's a couple on there right now (at high prices though, especially when you factor in shipping).
    It's just one of those "shouldn't have sold it, now I want it back" things :)

    Looking for my old ADM-3A

    I used to have an ADM-3A Dumb Terminal... fixed it up, and made my own lower-case ROM from a 2716 EPROM and a lot of small wires.
    Sold it around 2005 or so, but can't remember who bought it.

    I ended up using Win98SE and running PUTR without all the contortions to start DOS separately. Also I can run TeraTerm for file transfers to my PDP-8/A, and Kermit.
    Also working great.

    I removed the second floppy drive, dug out an old 540 MB hard drive (with Win 95 on it) and hooked it up to the PC. Started Win95, then "Restart the computer in MS-DOS mode", copied PUTR to the C:...

    John Wilson actually replied in depth to my post on cctalk! :)
    Bottom line is, my guess is correct that the program assumed only one floppy to transfer to/from a hard drive, and can't be easily...

    I'll check it out.

    I can't complain too loudly, given that this (free) program has been through many updates between '95 and '01 and hasn't been supported in nearly 20 years. But I am surprised...

    I also tried switching the PUTR disk into B: and the RT-11 formatted disk to drive A: (remounted). Same problem (tries to write over the source disk which is now B: even though the output filespec is...

    sure... http://www.dbit.com/putr/

    It's even weirder than I thought. First thing I did was make a backup copy of my MS-DOS disk (with PUTR.COM on it) by copying A: to B:. Then I set the...

    Correct. I downloaded 6.22 from the allbootdisks site and booted the PC from that disk. That's why I am so puzzled ;)

    Looks like I spoke too soon... although PUTR/DOS can *read* the B: drive, any attempt to *write* to it somehow clobbers the A: disk boot track! And PUTR doesn't return any kind of error - there is...

    Thanks, please let me know how the experiment goes.

    Meanwhile, I added another 3.5" floppy as B: in the WinXP box. I copied PUTR to the DOS floppy, booted the PC from drive A: , and started PUTR...

    I think it's a file system incompatibility... this useful page (https://www.legroom.net/howto/msdos)
    says that MS-DOS can only recognize FAT16 partitions.
    And WinXP is either FAT32 or NTFS. In any...

    Thanks for the Allbootdisks link. I made an MS-DOS 6.22 floppy and booted from it. But the only drives it "knows" about are A: and the CD-ROM.
    Where is C: ? It's definitely in the BIOS.

    I'm...

    Thanks for the info! I've read all of Mal's pages and find them very useful.

    I can try booting the PC to DOS (if I can find a disk!)... but why does the OS matter to PUTR? Please clarify further...

    I noted that a 3.5" 1.44 MB floppy is actually an RX23, and PUTR's instructions says it supports RX33 on 5.25" 1.2 MB media. Hmm.

    But the RQDX3 controller definitely emulates an RX33 on the 3.5"...

    In another thread, I chronicled my adventure getting a 3.5" floppy drive hooked up to my PDP-11/23+.
    It now looks to the system (RT-11 5.04 and TSX+ 6.50) like an RX33 with nearly 2400 blocks. So...

    As I suspected (and confirmed on cctalk), V5.04 is the first one that supports an RX33.

    I booted a slightly more recent RT-11XM pack which is 5.04 and it does notice the DU0: and I can read and...

    All the XXDP tests work and it recognizes the 3.5" HD floppy as an RX33. So far so good.

    But RT-11 (5.01) does not see the drive as any of DU0..3.
    I'm assuming there is something I have to CONFIG...

    It works! :)

    Yet another self-inflicted injury. Despite checking the orientation of the 50-pin cable between the RQDX3 and the M9058 more than once, somehow I'd managed to get it upside down where...
