Have been getting a RaSCSI updated to PiSCSI which never did workout using a headless Pi Zero installation; not a realistic process, however did get it working by putting a Pi 3B in the mix. After removing the PiSCSI (w Pi Zero W) from the case I noted it was really hot almost to the point of...

Sorry if this is obvious or posted somewhere else, but I have a Macintosh plus that chimes and then HAD a small postage stamp with smiley face and no error code. After a few off and on's, it now has a thin line the width of a postage stamp in the center of the screen. It still chimes and I...

Cannot remember how I ended up with this board (one of 3 nonworking SI boards I've collected over the years) but it is nonworking (no chime, no video) and has been recapped. Whenever I think of replacement by tantalum capacitors, I am looking for a positive and a negative. Are these bipolar...

My SE recently just crashed, no screen, no noises, no bong, no disk drive. I thought power supply and wanted to get inside to look at the boards anyway so just thought I'd remove the power supply to check directly. The Sony Model CR-44 power supply has a sticker on the side with pins and...

Just adding these for possible informational purposes for any cloners out there. All photos are the same system/card.

There is a persistent graphics glitch on on recently obtained Cube. Attached are pictures with the computer booted and the other is the pattern on the screen between shutdown and complete power off, i just thought it showed the pattern the best. The glitch to the right of the mouse moves with...

I have a C2N Datasette that will not load tapes. I've looked at the schematics, have put an oscilloscope on the read heads, watched several repair videos/tuning instructions. I also have a working SD2IEC. Why do I care if the C2N Datasette works or not?

Is this a picture of the 7100/80 L2 cache? If it is, is it worth replacing for computer function. I have a 7100/80 using the DB15 for video and if this chip is installed the computer will not boot but does boot when I remove it.

I have been looking for a Iici locally for several years and actually bought a "lot" of computers to get this one. Even when I heard something shaking around, it still never occurred to me.

Its a few decades late but pretty neat. Thanks to the 8-bit guy (ATTACK OF THE PETSCII ROBOTS) and Scott Robison (C128/dual monitor version. Yeah...it is a blast to play too.

This is an external 3.5 inch drive, model number is consistent with 800K. The cable was cut off but it does work as I've tested it with the cable from a 400K external drive. I want to build a cable and have a 20 pin ribbon cable and have ordered a 19 pin male DB connector. Is this a straight...

Does this mean anything to anyone? It runs basic....maybe bios modified for the Claxton school's VIC 20's? Never considered the VIC 20 much of a school/educational machine.

Replaced two bad SID's one with a nano Swin and the other with BackSID (from Backbit) and both work well. The BackSID has support for paddles and mouse whereas the nano swin does not. If I had known the nano swin did not support the paddles and mouse, I would have gotten 2 BackSID's instead. I...

Background: At my home, occasionally on older systems and old Atari's that when I power up, the screen has a wavy horizontal line of variable intensity, typically about 1/8 of the screen that slowly rolls/scrolls upward continuously. Inparticular, I had noticed it with a gamecube using a 3rd...
