Cool Patent Artwork (Apple II and others)

Hello All,

I ran in to an artist at the Pittsburgh Three Rivers Arts festival this year that had some unique artwork. I purchased a few of the Apple patents from him to frame and hang on the wall. I thought this was pretty unique artwork and super creative. What he does is researches patents for iconic inventions, takes a professional photograph of the item, extract the main elements of the patent (drawings and text) and then brings it all together into a collage on really high quality paper that is suitable for framing.

F8 ROM

I have an original Apple II computer with what looks like integer basic ROMs. However the F8 chip is not the typical 3410004
It is a

Synertek
7845E
C48037
AIMB-F8

For some reason, I can not get a beep or a prompt, while booting to the integer basic ROMs. I do get regular video.

I do get a beep and a prompt when using a ROM card with apple II + ROMs.

ROMAGEDDON!

Together with a FrankenApple there were a lot of different ROM chip included.
Most notable are 1 set of 4 '78 Integer Roms (1-4) as well as a single '77 Week 51 F8 Integer ROM.

Most of the custom ROMs seem to be for use in a Mountain computer ROM+ card.

Several programed 874x type MPUs were included as well.

UPDATE: some Roms are now in the ZIP archive.

There were some modified monitor ROMs as well as several tools for ROM testing.

Source for Apple II ROM images

Hi All,

Is there any online source for the various ROM images on the //e and more importantly the expansion cards? I know Reactive Micro is selling burned EPROMs at $10 a pop, but I have my own burner so I just need the images. I'm assuming the problem with my SCSI card is a degraded EPROM, but would rather not start investing money if that's not the case.

Thanks,

Beo

Apple //e Motherboard problem. Please help!

I am trying to fix the motherboard to my grandfather's old //e, and have run into a bit of a problem. The board had been behaving rather strangely (not running internal diagnostics when the keyboard was detached, and giving errors for the RAM, and MMU). I've tested the chips on another board to see if I could replicated the error, but they all tested "System OK" on the new board. The most consistent error I was getting was in RAM socket #7, so I tried spraying it with some contact cleaner.

Cms scsi card

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

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.

Search for IBS AP14 Floppy Controller Software

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

IBS AP14 is a disk controller interface card for the Apple II computer, which was developed and distributed in the 80s by the company IBS Computertechnik in Bielefeld, Germany.

Unitron 2000 keyboard

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

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.
