    accelerator silliness

    I just picked up this wonderful thing at VCFMW from @zigzagjoe Time for some shenanigans before doing something more practical with it... The Carrera CP allows on-the-fly switching between the Carrera and the DiiMO...

    recreating my first PC build

    In late 1998 I was 15 and I built my first PC...not my first computer, but the first one I built from scratch. Over the last year I've been gathering the same components I used back then with the intent of recreating it. The original specs were: Soyo SY-5EMA+ motherboard with 1MB L2 cache...

    SE/30 reloaded no bus activity

    I'm putting together another SE/30 reloaded and populated it to the point where it should chime. However, I'm getting absolutely no activity on the address bus when scoped at the CPU. The symptoms are a simasimac image and no chime of any kind because the CPU isn't walking the address bus and...

    tinkering with compacts all winter?

    Looks like I will be :) I recently discovered that another forum member lives less than an hour away and needed to downsize their collection. After making a carefully prepared and well researched presentation to my wife, she gave me the green light to go pick these up: There's a 128k, 512k...

    RGBtoHDMI fun

    After finding external video adapters in both my Classic and SE, I've been wanting to build an RGBtoHDMI. Well, I finally got my hands on a Pi Zero and all the other parts, printed a case, and assembled one. @Mu0n 's stickied thread was a big help. My 030 Classic came to me with this...

    MacTilt

    Was looking for something in the basement today and forgot I had this. Anyone used one before? Is it stable or is it as precarious as pictures make it look? Suppose I should put it under my SE and find out :)

    Is this IIgs board a ROM0 that was upgraded?

    I've had a IIgs "Woz" edition for awhile, and I finally took it apart to recap and retrobrite. It's always reported ROM1 when booting, so I kind of assumed that someone had just put the Woz top on a non-Woz machine. However, when I got it apart, I noticed a few things: The logic board is the...

    Apple II SCSI hard drive questions

    Anyone have experience using SCSI hard drives with an Apple II? I have yet to ever use a hard drive of any kind with any of my Apple II's, so I have no clue where to start with that, but I found this CMS SCSI card in one of my IIgs's: I also have this CMS model SD30U external SCSI drive...

    my $10 estate sale find

    Wife and I went to an estate sale today and found a lot of neat 80's computing promotional materials and catalogs, books, and TRS-80 and Osborne software. I initially saw the Osborne and CP/M books in the bedroom (a little light bedtime reading?) and grabbed them because I own a couple...

    found this ADB switch...is it safe to use

    I just found this buried in a box: I know hotplugging ADB is generally frowned upon and has even damaged some boards. I wonder if this thing is safe to use, or if it would change ADB bus IDs and screwball my mouse settings or something?

    Radius Stage II Rocket in a IIci

    I finally replaced some corrosion-damaged ICs in my dad's old IIci, recapped the PSU and logic board, cleaned/lubed the floppy drive, and it booted right up. As you can see, he had some goodies installed: Front-to-back are a Daystar 040 accelerator, a Radius Stage II Rocket, a Radius...

    MicroMac Power Workstation

    I posted a picture of this on Discord and received a lot of questions and requests for pictures. Apparently it was questionable whether any of these ever actually existed. Well, at least one of them did :) I called my dad (original owner) to ask him what he remembered about it. He thinks...

    6100 won't chime with heatsink installed?

    I just finished recapping my 6100's logic board. I also removed the heatsink, applied new thermal paste, and reinstalled the heatsink. It booted fine before doing any of that, but wouldn't chime afterwards. I triple-checked all the new caps, and everything looked good. I then removed the...

    660AV battery bomb

    I guess the silver lining is this is the first system I've encountered with battery damage: The chassis is pretty much completely rusted-out. I cleaned up the logic board a bit with vinegar and isopropyl: The NuBus adapter had some damage as well. I scrubbed some of the corrosion off...

    Radius SpigotPro AV...help me identify this component

    I have a Radius SpigotPro AV card that was installed in a battery-bombed Quadra 660AV. The card looks OK except for a single oscillator who's casing is completely corroded: I'm trying to identify that oscillator so I can replace it. I tried removing the corrosion with no luck. The only...

    found this little guy...

    ...in a bunch of retro stuff I recently came into. I haven't tried it yet, and I never used one of these back in the day, but it sure is...cute.

    Osborne anyone?

    I'm thinking about going to Starbucks and plopping one of these down on a table amongst all the laptops and getting my WordStar on :) These both looked like the one on the left before I fixed them up:

    dad asked "do you want this junk in my garage?"

    So I've had this lot for awhile now and it keeps growing. My dad lives in TX and I'm in PA, so it makes its way up to me a little at a time. I unfortunately haven't cataloged everything, but here's some of what's here. Most things listed as "in-box" are not only in the original box, but also...
