Okay. So if I'm understanding this correctly, I have a fully functional Iici, but I either need a different VGA adaptor, or different monitor to test the motherboard video. The thing is, the monitor usually tells me if there is an incompatible signal. It was doing that with the NuBus card...

Not really a huge deal, but it would be nice if I could get this fully functional. Just as the title says, I got a Mac IIci that came with a NuBus video card and an Apple branded IIci Catche Card. It needed a full recap, and the battery was dead (since removed). Other than that, it was just...

Have a Macintosh Iici that suffered a bit of damage to the processor. I managed to remove it. Only lost a bout 7 pads, 4 of which were no contact. With a little bit of luck, I think I can fix this. But I need a replacement. Any suggestions?

Yes. I have a Language Card. However, it's not being recognized when installed, either by DOS or diagnostic software. There was a RAM issue! I basically had to strip it down to its base 16k and then work my way up to a full set of working chips bank by bank, but it now loads programs from...

Recently got a Rev.2 Apple II board. Originally had AppleSoft ROMs, But the AutoStart had a bad pin (broke off) so I replaced them with an Integer set I had on a II+ board. The board boots to the Machine Monitor, and with a ROM switch card (AppleSoft onboard) in Slot 0, it will go to BASIC. I...

Sadly no. The neck card is low voltage. That kind of arching is caused when the CRT no longer keeps a vacuum.

Yup! Cracked joints.... Or so I'm guessing. I've reflowed these connections at least five times, but ended up desoldering and resoldering the connector to the motherboard and it seems to be holding. Fingers crossed. Thanks all!! :)

The last time I saw something like that was on my Commodore PET. The stem of the CRT had been broken off just past the neck board. If the sound you hear is similar to the sound in the video, it's likely be electrical arching inside the machine. Unfortunately, it means that you will need a...

Just as the title says. The screen goes black after about 5 to 10 minutes of use. Hitting it on the side with the analog board will bring it back for a few seconds at best but with diminishing returns every time. The good news is that the computer boots and loads an operating system. SCSI port...

I recently came across the 13 sector ROMs for a Disk II Controller Card and thought I'd give them a try. But before I do, I wanted to know if a 13 and 16 sector card can peacefully coexist on the same computer? Or would I need to designate a separate machine? (not my preferred solution since...

As long as the monitor is monochrome, then yes I can confirm that it will work. I live in the US, and I've hooked up a PAL C64 and ZX Spectrum to my Apple Monitor /// without a problem. Just needed a minor adjustment to the vertical hold.

Unfortunately, the //c defaults to the internal drive when booting from 5.25 disks. I believe you can still boot 3.5 (800k) and smart HDD images externally, but you will probably need to open the computer and attach the EMU to the internal 20 pin socket to boot a 5.25 (140k) image.

The garbage you're seeing on screen is normal for the age of the machine. My //c does the same thing (also one of my //e's). From what I understand, it has something to do with the aging of the RAM chips. Older chips seem to retain their memory for a bit after power-off, causing glitches when...

Thanks for all the replies, and sorry for not responding sooner. It's really interesting to see all the info on the ]['s extended lifespan. I really didn't expect to learn that it went on as long as it did. As for my board, I'm pretty sure it's a ][ now, though it likely started out as a ][...

I recently got this board off of eBay and was wondering if it is what I think it is (i.e. an Apple ][ board and not a ][ Plus)? I think it is... At least it looks like one, but the date codes are from 79. The info I found on when the ][ was canceled is contradictory. Some say 79 while others...

I tweaked this program from something I saw on the 8-bit Guy. Managed to get the wave to fill most of the screen, repeat, and end where it begins on the screen. However, I was wondering if I could get it to scroll horizontally across the screen? or draw from right to left? I don't know, I'm...

Possibly fixed! The 74LS195 at C2 was in backward and I didn't notice it. Swapped it out (as turning it around revealed that it was fried) and so far the computer has come back to life! Also., the keyboard seems to be fully functional as well!

OK, So good news! The PSU is fixed and giving out good voltages! Also, the keyboard is working to the best of my knowledge. Bad news. The motherboard is giving me no beep and no video?

New problem. The power supply blew! Bad RIFA. Popped, spit smoke, no -5v on board. Sadly, I'm going to have to go over it before I can proceed further.

Thanks for this! And sorry it took me so long to respond. I ordered them and they should be here in about a week! Unfortunately, I have another problem. The garbage screen is back, and I still don't know why??? I've tried every socketed RAM chip on the board in an Apple ][ Plus and every...
