    Mystery Serial Card (Microtek SV622)

    Hello! I ended up with this serial card on eBay, hoping I could save a few bucks and not have to get a Super Serial Card. Unfortunately, I did not do sufficient research, because as I have found, there is next to nothing about this card online. While it's definitely a serial card, based on my...

    Question about Dallas clock chip modification/bypass

    Hello all! I recently bought an FIC 4386-VC-V motherboard from ebay. Unfortunately though, it has one of the Dallas clock chips. Now, I've seen the replacements for these, whether they be the Necroware stuff or just a new Dallas chip. However, on the back of my motherboard, near to the clock...

    Weird 5170 Floppy Issue

    Hello guys. I'm having the weirdest issue with my 5170 and 1.44mb floppy drives. The issue is that whenever I try to go into the A drive (1.44mb), the screen blanks out and I have to reboot. This does NOT happen with the B (1.2mb) drive, I can get into it and access the files fine. Additionally...

    TI Color Graphics Controller Card

    Hey guys, I recently bought a 5170 which came with this pretty cool card in it. As the title states, it's a TI Color Graphics Controller that was apparently primarily meant for the IBM Professional Graphics monitor or TI's version of it. I was perusing through the manual because I'm having...

    ISA Archeology

    Hey guys, thought you might be interested in this. I recently bought a 5170 and got a couple of interesting cards in it, one of which is this "Texas Instruments TMDS 34 7180 400 Graphics Module". Apparently it has something to do with displaying bitmaps, I'm really not sure. By googling the...

    Best way to paint/restore a 5170

    Hey all, I just wanted to ask a quick question of the sages of this great hobby. I have a 5170 that is in somewhat rough shape and possibly with a bit of rust coming in the mail in a few days. Since this isn't particularly pristine, I figured I would use this as my first restore attempt and...

    Running PowerMac G5 Without Radiator Fans

    I just received a PowerMac G5 with the dual processor setup today from eBay. It does work, but for whatever reason, the fan assembly that cools the water cooling area or whatever you want to call it is gone. So in theory, if I run it, the only cooling for the processor would be the rear exhaust...

    EGA on 5153 Monitor?

    Hey guys, I just recently bought a dual EGA/VGA card, a Heath 105-307-3. This got me looking into buying a 5154 monitor, but then I discovered some of the pitfalls of that particular monitor. Not only is there the price, but it's seemingly a bit unreliable. I've ended up finding out that it's...

    Anyone familiar with setting up Sergey Kiselev's 8 Bit ISA HD Floppy Controller?

    Hey guys, I just got one of these in the mail today and have been setting it up. I've got it working pretty smoothly except for one teeny thing, which is the thing I bought it for: I can't get it to read 1.44mb floppies. I have everything set up seemingly pretty well, I've tried it with the...

    Troubleshooting a Socket 7 Motherboard

    Hey all, I just bought essentially a system without a case. It consists of a J-Mark J-656VXD motherboard with 96mb of ram and a Cyrix 6x86 processor. The system SEEMED to work before it was shipped, according to the buyer and his photos. It worked when I first started using it as well. What it...

    Manual for J-Mark J-656VXD Motherboard?

    Does anyone know where I can find a full manual for this board? It's a pretty decent board, seemingly. I currently have a Cyrix 6x86 in it.

    How can I find out what kind of floppy controller I have?

    Hey guys, I have a 5150 setup with a couple of 360k drives in it. I got to looking at the floppy controller, because I was hoping that maybe, just maybe, I could get a 3.5" drive working on it because that would be extremely helpful to me. I doubt it, honestly, but I think it's worth a shot...

    I only have a half height, leaving 1/4 of my drive space a giant hole and it's quite unsightly. Not sure how much something like this tends to go for normally, so if you have one, just let me know what you want for it and I'll get back to you on it.

    Storage Solution for PS/2 Model 70

    Hello, I am just starting my collection of vintage computers and bought a PS/2 model 70. At first, I was expecting there to be ISA slots but to my great disappointment I found out that there are only proprietary MCA slots in this model and it came with no HDD. Fortunately, the floppy drive and...
