    Can you tell if the power supply fan starts? If it has the full 640K of RAM, it will take about 40 seconds to finish POST before it will beep.

    Any chance you were in the CMOS setup and somehow removed the entry for drive B:? I believe if the system thinks there is only one floppy drive it will access the A: drive when you ask for A: or B:....

    I believe the composite output depends on the RF modulator. The STs that did not have an RF modulator did not have composite video available. This, at least is true of the 1040 STf model I have,...

    You should have gotten some kind of display with what you have. Your 520 sounds like it is the same or very similar to mine, and mine displays the green desktop with the mouse pointer and the menu...

    I'll be dipped! Looks like I tediously modified a couple of PC floppy drives for no reason. I obviously never looked for the DC or ready lines in the pinout diagrams. I have read repeatedly about...

    The floppy drive will work without the DC line, but you have to be careful to close any windows to the disk that are open before you eject the disk or corruption can occur, or so I have read. I have...

    I have a 520 ST currently setup. The original form factor with TOS in ROM, an external power supply, and no internal floppy drive. I just tried booting it up with the floppy drive disconnected, and...

    Resistors that burn up like that almost certainly did so because of a short somewhere in the circuit. It's a good bet a replacement resistor will fail the same way.

    The hard drive might be gone, but the "Invalid Configuration" message indicates that a dead CMOS battery is the likely culprit. The hard drive parameters are stored in CMOS , and if that data is...

    I have modified a standard PC 3.5" floppy drive to work in my ST. The drive needs to be set as drive 0, or the first drive, instead of the typical drive 1 setting for PC drives. Also, the disk...

    I'm not familiar with that specific machine, but it sounds like a floating ground to me. I would maybe take a look at the ground connections to the power supply. In photos of the motherboard online...

    Do you have a drive connected? These cards will report a host adaptor failure if there is no hard drive detected.

    The trouble with the Predictas is they were Philcos. Not the best crafted televisions of the era. You may find you have to duplicate component packs. Entire sub-circuits encased in epoxy. Age,...

    Z-RAM-3D ST ram upgrade module.

    Hi all, I bought a pig in a poke on eBay the other day. It's a RAM upgrade board that was removed form a "working" ST. It's called a "Z-RAM-3d/4Meg." by a company called Zubair Interfaces Inc. ...

    Rana 1000 disk drive

    Hi all. I have been collecting third party disk drives for the 8 bit Atari, and I finally managed to get a Rana 1000 a while back. The drive didn't work, and after chasing that problem for a week,...

    Gettting the 8 bit controllers working on a 486 board can be tricky. Many 8 bit cards will let you disable the on board BIOS via jumper. The WD1002A-WX1 for instance can have the BIOS disabled by...

    Miracle of miracles, I found the packaging for the card I have. It's a Bytecc PCI Express Controller, Part Number BT-PES322i. I tested a 170meg Western Digital drive just recently.

    My apologies. I started my post before I realized I wasn't going to find a way to identify my card. It has "GEN-115 E330731 94V-0" printed on the card, but when I search those terms I just get...

    It's not quite that, but I bought a PCI-X slot card with two SATA and a single IDE port that I use under Window 7. It required a driver, but has recognized every old IDE drive I have connected to...

    I fear that there is every chance that if you leave the drive off for a few days, it will stick again. If you can access the spindle motor flywheel under the circuit board, nudge that to get it...

    I dug out one of my 5160s, A 256K model with the 11/8/82 bios. VGA card, single 360K floppy drive and standard IBM floppy controller with the motherboard switches set for a single floppy drive. I...

    I most definitely tested this in a 5150 which just boots from the floppy, no problem. I think this must be a combination issue. 5160 as well as the WD controller with Super Bios. My 5160 test...
