ROMAGEDDON!

Submitted by stynx on July 17, 2018 - 3:28am

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

Submitted by Lord Beowulf on July 16, 2018 - 10:27am

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!

Submitted by DistantStar001 on July 14, 2018 - 1:20pm

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

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.

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?
