    Just applied a windows 1.0 - 3.1 inspired boot image to my amiga before my Philips monitor exploded, luckily it only looks like a 200 Volt capacitor has blown, it's bulging at the top, the return transformer looks okay.

    I've got a really old dell at the foot of my bed, No clue what model as the plastic casing is missing, The keyboard is downright painful, When i didn't have a USB one i had to use it, The angles are so sharp i genuinely got blisters. And it's a "Quietkey" when it was louder than my electric typewriter.

    Edited:

    By really old i mean the startup DELL splash is in a 16-bit monochromatic display.

    BuMP.

    Upgraded my Pedion from a generic 2gb hard drive to a 4gb Compact Flash Card.




    Also uncovered a matched set of RS-232 encryption/decryption cards. You program them both with a cipher and that allows for you to run a secure connection between two computers. Remove the metal ocver in the card and a switch kills battery backed power to the ram that holds the cipher, effectively making it impossible to communicate witht he system ont he other end.



    Also installed Enhanced BIOS patch card into my Compaq Portable III which permitted it to auto-detect hard drives and enable me to install a much larger and physically smaller laptop hard drive.




    Currently working on figuring out how to add good enough speakers to my Sound Blaster 16 card. The ones I previously tried require too much power and are not loud enough.

    I had might aswell dredge this thread up with some content again.


    IBM AT PC 5170. £70 for everything pictured.
    Best Birthday present yet!


    And MS-DOS 3.2 sealed in it's envelope. The manual puts the Bible to shame...

    Edited:

    MIPS, do you know any way of getting an IDE HDD or Compact Flash card booting in this thing?

    Because I really don't trust these 25 year old Seagate drives. Apparently they just loved to improperly retract the read/write head when you shut the computer off.

    Hey folks! I'll be demonstrating one of my systems this saturday while attending the monthly meeting of the Seattle Retrocomputing society.

    I'll be there from 1:30 to 5PM but I recommend you stick around. Last time we went upstairs to where the real hardware lives.


    You're also only minutes away from one of Seattle's finest used computer component shop. RE-PC.

    the 5170 thankfully has a 16 bit ISA bus so you will have a much broader access to to better hardware. Personally I would go for one of Adaptec's ISA SCSI I/O cards which integrated the floppy controller and a bootable SCSI bus but you probably don't have SCSI drives laying around. Instead you can just hunt down one fo the many Generic IDE I/O cards that were around int he 386/486 era. They normally included onboard support for two IDE drives, two floppy drives, two serial ports and a parallel port however drive detection and configuration was usually at the mercy of the BIOS. You'll have to find one of the Enhanced BIOS cards like I posted above to have automatic drive detection.
    If all else fails I still strongly recommend either a 20mb ST-225 or 40mb ST-251. These two drives are quite possibly the most reliable hard drives ever built. You can still find them in full working condition. When in doubt though, format the drive and then do a scandisk surface check. An AT is generally a 286 so I would recommend MS-DOS 3.3 to 5.0

    Already got one of those drives, and a ST-4026



    Edited:

    Looks like I will just be keeping them.

    Edited:

    And it comes with IBM PC DOS and MS-DOS 3.3, so I'm in luck.

    Excelent, I will have it running as soon as I get a new RTC battery. Apparently all of the BIOS settings need reprogramming in basic too.
    Thankfully the old one missed the motherboard when it leaked and pissed acid allover the inside of the case.

    If you don't mind monaural sound, you can build a cheap op-amp with a TDA7052a on a small 1.5"x1.5" PCB and power it with +12v from the PSU. You'll probably want to use a power regulator and a capacitor to filter the power though because the computer's PSU has too much noise.

    For stereo, you could use dual TDA7052a's, or use a larger stereo op-amp.

    The older Sound Blaster 16 had an onboard amp for driving some small speakers but that seems to be a hit and miss thing when it came to which speakers worked fine with the onboard amp and which ones like this one were too demanding.

    If the SB16 had an op-amp, it was only meant to drive the small 8 ohm PC speaker that most cases have. You'll have to build a more powerful one if you want to have internal stereo speakers.

    The Sound Blaster 16 featured the then widely used TEA2025 operational amplifier which, in the configuration Creative had chosen, would allow approximately 700 milliwatts (0.7 watts) per channel when used with a standard pair of unpowered, 4-Ohm multi-media speakers.
    Those flat disc speakers are .4 watt, 4 ohm and I can barely hear them.

    If you're using the SB16 under DOS, the Creative driver bundle should have a sound mixer application (the AWE64 does) where you can crank up the sound, which should make the speakers louder.

    If that doesn't work, check to see if the TEA2025 is a discrete IC on the SB16. If it is, locate pins 7 and 10 on it. There should be a resistor to ground on each pin, along with a capacitor. Changing out both resistors for two potentiometers will let you manually adjust the volume level. You can also try and use a different value resistor, but if they're SMD resistors, they're a pain in the ass to replace.

    The original Sound Blaster 16 (my favorite card because it had the most awesome features (you could add to it like the CSP and Yamaha wavetable daughtercard) has no software volume control. There's a volume control on the bulkhead face of the card.



    Fatal-Error: Find a terminal program for DOS. They are everywhere.
    Hell, find Windows 1.01 as it included a terminal application and I know for a fact that it works on the AT.

    I used to have a Athlon @1GHz with a starfighter AGP but that died. so I guess I will use a ATI rage or a 4650.

    You can get SD card adaptors for the cartridge port, doesn't that seem a little more practical?

    Unfortunately I got bad news.
    When I lost my job with The Hackery in August I lost not only my job obviously but all my Vancouver connections for old shit. I have not gotten anything cool since I left. :(
    If you contact The Hackery directly they might still be able to sell you a 1541 drive but for the last few months I have been completely shut out of all operations at the place.
    Sucks too. They got in a bunch of Teletype gear recently.
