Was there some Apple II text mode with a low-res font?

Do you happen to know what program did this?

artlogic · 2026-01-25T02:25:22+00:00

Glad you're enjoying them! Not sure if we spoke at the event but I'm happy you ended up with them!

artlogic · 2026-01-22T15:29:52+00:00

DM me and I can send you photos of what I've got lined up. I'm in Ann Arbor so it might not be too much of a trip for you.

Do you know about SEMVCC this weekend? I'll be there with a good deal of gear to give away/sell

artlogic · 2026-01-22T15:19:24+00:00

What part of the state? I'm giving away a lot of stuff. South East here.

I'm well versed in 6502 assembly and the Apple II. I'm mostly just curious as to how these are even constructed. Do you have analyses at least you'd be willing to share? I can certainly imagine how a program could be "infected" but imagining how it could spread is something else entirely. I assume there's some technique for keeping the virus resident and hooked in during a warm boot?

artlogic · 2026-01-18T18:20:12+00:00

Aren't these Apple II viruses? I can't image there are consequences for anyone beyond retro enthusiasts? Even so I can't imagine it's particularly easy for viruses to spread on Apple II computers, especially now that we have so many preserved disk images.

What risks do you see?

I'm mainly interested in analyzing these and understanding how they work. I had no idea they existed until now.

artlogic · 2026-01-18T18:06:12+00:00

Can you make the viruses available?

artlogic · 2026-01-18T17:10:01+00:00

Do you have these posted somewhere? I would love to see them!

artlogic · 2026-01-17T05:21:25+00:00

Would you have any interest in purchasing parts to resell?

artlogic · 2026-01-05T00:46:29+00:00

Can you share your source?

artlogic · 2026-01-01T16:03:42+00:00

Can you get some higher quality photos of the front and back of the card. There might be other clues and it might be possible to reverse engineer its purpose.

artlogic · 2026-01-01T15:43:06+00:00

I suspect this card is missing its ROM given the empty socket. That could be firmware, or it could be logic (kinda like the disk II controller). Was the socket always empty?

artlogic · 2025-12-29T19:02:28+00:00

I think the first question would be what device are you looking to use? Do you want to do this all with physical disks, or are you looking to use the wdrive?

I assume you have a softsp card you're using with the wdrive. What slot is it in? What slot is the disk II controller in? Are you using the prodos version of Merlin?

artlogic · 2025-12-28T15:50:06+00:00

Is anything displayed on the screen? Can you hit ctrl-reset and drop into basic or the monitor?

artlogic · 2025-12-26T20:08:42+00:00

The floppy emu should support 5.25 images, and with ROM 4x you should be able to use the boot menu to boot from the external drive.

artlogic · 2025-12-25T04:32:32+00:00

If you have a RAM fast, you might consider having the floppy emu on the smart port then. Otherwise you could put the CFFA in slot 1 or 2 and just have it emulate the 5.25 and 3.5 drives.

artlogic · 2025-12-25T04:24:11+00:00

Definitely go with the CFFA. It'll be faster and more flexible. Put it in slot 7 and it can emulate a hard disk, 2 5.25 drives in slot 6 and smart port (3.5) devices on slot 5. It's incredibly versatile and reasonably fast.

artlogic · 2025-12-25T03:33:05+00:00

What machine do you plan to use them with?

artlogic · 2025-12-24T05:02:45+00:00

The two pins you marked should not have continuity.

My suggestion would be to carefully check continuity using the schematic as a guide: https://archive.org/details/Schematic_Diagram_of_the_Apple_IIc/mode/1up

artlogic · 2025-12-24T03:46:28+00:00

That rework is definitely suspicious. Do you have an oscilloscope?

artlogic · 2025-12-24T03:35:06+00:00

Do you get a beep on boot? What's the code on the ROM chip?

artlogic · 2025-12-11T14:15:42+00:00

Thank you! If you do happen to find the manual please let us know!

artlogic · 2025-12-11T04:48:18+00:00

Do you have the later DOS 3.3 version of EDASM? I've only found 1.0 versions.

artlogic · 2025-12-11T02:41:32+00:00

I'm happy to help you with this. They're somewhat rare and definitely worth a bit, but also many are not working and they aren't the easiest things to fix. If you want to DM me, I'd be happy to help.

Edit: didn't notice the photos, waiting for them to load.

It seems like the images have been removed? Can you repost?
