Cms scsi card

Submitted by inzgary on July 13, 2018 - 12:44pm

Hello I'm looking to hook up a scsi hdd to my apple iigs. I am considering a cms card because they seem half as sought after by collectors as the apple cards. The drive I'm hooking up is a quantum hdd in a hobbyist's scsi enclosure, which I've never seen before but it powers on and does its self test just fine. Would a cms card be a good option?

Pulling block data from SCSI drives

Submitted by Lord Beowulf on July 12, 2018 - 1:06pm

Looking online for PC SCSI adapters it looks like I may have waited too long at this point, but it's been my plan for many years now to one day fire up my old Apple //e SCSI hard drives and rip all the content off to run on PC emulators (not to mention get to old college papers, etc.). While chances are slim there's anyone here who would remember, I ran Wunderland BBS until the mid 90s on what I would suspect was the most souped up Apple //e ever to exist. With 1 MB RAM, 8 MHz ZIP CPU, and 1.3 GB!!! of hard drive space, at the time it was a monster.

Does anyone have image files from the floppy disks that came with the IBS AP14 floppy controller board?

Unitron 2000 keyboard

Submitted by falter on June 30, 2018 - 4:38pm

I have this exact keyboard here.

Some years ago, while I was trying to trouble shoot problems with an A2S1 not typing, I tried using it there and something must have blown up, because after that it wouldn't work with anything.

Apple IIc+ Disk Problem

Submitted by DaveiicPlus on June 28, 2018 - 11:22pm

I'm working with a user in Europe to debug an Apple IIc+ that he purchased from me. When I had it, it powered up and generated video, but the disk operation was untested. It had been in storage for an extended period of time, and I never had any disks for it to use for testing.

Focus IDE HD Broken?

Submitted by 04 Intimidator on June 27, 2018 - 6:21pm

I purchased a Focus Drive a number of years ago and finally got to installing it. I keep getting an error reading the drive, there is little information I can find, and cannot even verify if the card supports this drive or if the drive is even the original one. Since it was crated in 1998, it should support it, but I do not know enough about the chips or software.

Could anyone lend some insight?

Disabling a card to free up a virtual slot.

Submitted by grimakis on June 27, 2018 - 11:04am

Hi all,

Somehow this posted without the message.

I'd like to be able to assign my CFFA3000 virtual Disk ][ to the same slot as my real floppy drive controller. That way I could switch betweem the two without opening up the computer. At first I thought to cut the Ground trace on the card, and wire in a switch to turn off the whole thing. However, I am wondering if it is possible to disable the physical card with a machine language routine?

Help! First time Apple IIe user.

Submitted by amartin256 on June 26, 2018 - 9:45pm

Hello everyone,

I just bought an Apple IIe platinum from an antique shop. It turns on and I know that the ROM works because we loaded up a program they had. I brought it home and power it on but can't get anything to happen. I turn it on and get this screen but nothing else works. Please help me figure out how to work this machine. Every video I watch does not have this issue.

Graphics Error in II Plus

Submitted by kwilburn on June 26, 2018 - 3:06pm

Hello!

In the past few weeks, I acquired an Apple II Plus that seems to have a graphics error. Whenever I attempt to boot the computer, vertical lines appear instead of the normal startup screen. I don't know if a chip is fried or what. I've added a high resolution image of the motherboard below for reference. Any help is appreciated!

Thanks
Kevin

P.S. - I should add that I'm an amateur when it comes to pre-mac era Apple machines and this is my first Apple II.

IC question

Submitted by kchrister on June 25, 2018 - 8:56pm

Hi I am fairly sure these questions have been asked before, but I am unable to find the correct thread.
I am trying to find the parts for an empty (totally stripped Apple IIe motherboard). I have questions about to chips. I am reading the Apple IIe Repair Guide by Double Density on A2OL, in the inventory list they mention IC MC741 (OpAmp) in location A11, is this the correct chip, or can it be replaced my an LM741? I know I will most likely not ever need it, as it is the amplifier for the cassette player, still I like the board complete.
