Hey everyone! We've been having issues with being bombarded by forum spam bots. As a temporary measure we're disabling registration for around 72 hours. Anyone wanting to join up as a legitimate user, please have patience! :)
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...
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...
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...
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...
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...
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 :)
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...
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...
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...
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?
Finally got this thing 100% done!
full recap of the PSU and logic board
replaced HD with a BlueSCSI
new thermal paste on both CPUs
added a slim, quiet 80mm fan behind the inlet vents
264MB RAM on the Mac side
32MB RAM on the PC side (PC wouldn't boot with a 64MB EDO SIMM installed :rolleyes:)...
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...
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...
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...
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...
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...
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:
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...
