Nice - thank you!

Acquired an 850 that is in good shape minus a decal on the front. Does anyone have a high-rez photo of one or other format I could take to a print shop to have one made?

Ohhhhh that is cool. I didn't know about these, thanks! I have a Fujinet for my Atari and I see they are working on one IIe (? I think). Don't know if it would also work on the IIPlus when it comes out.

The computer still works. Which card are you referring to replacing? The one on the Disk II or the interface card itself?

New to Apple II Plus and think I screwed up big time. I bought an Apple II Plus system at an estate sale and it has a u-Sci (Microsci ?) drive as drive 1 and an Apple Disk II as drive 2. I couldn't get the u-Sci to boot any disk so I thought I would try swapping the ribbon cables on the Disk II interface card. It was easier for me to do this with the card out of the drive. (By the way I had the cases off of both drives to clean the heads and never put them back on while doing the tests.) I took the Disk II card out (of slot 6) and swapped the cables (actually now that I think about it I just put the Disk II cable in the Disk 1 connector and didn't reconnect the u-Sci). My own fault, I put the Disk II card in slot 7 instead of 6 without noticing what I did. I turned the computer on and POP & the magic smoke came out of an IC on the Disk II analog card, which I saw & smelled all too well because I had the case off of it. Chip ULN2003 - I think Darlington Array. So, I can get a new ULN2003 but 1) is there a way to see what other things I blew on there (if any) 2) I guess I should mark slot #7 as "DO NOT USE"...? lol Cheers Dukester

I haven't been getting them since Thursday. Related to any of the current events or just one of those things? Cheers

So I am getting closer to archiving the disks I have that are still good, which amazingly, is most of them after 40 years. Anyway, I've been digging up and reading the old posts here about archiving disks, like this one: which I found very helpful. While I could do it that way, it would involve creating a spreadsheet or db of what's on what disk (I was not that organized as a teenager back in the day). Most of my stuff is not single programs on a disk, like commercial games or applications, but collections of stuff I wrote myself or typed in from magazines. What would be more useful to me is the ability to have multiple files (or even better, all the files from all the disks) in a single archive, like on a modern hard drive file system. Is that possible with something like a TNFS connected share via FujiNet? I would love to be able to then access this emulated hard drive, or the like, from Altirra in addition to my 8-bits. How did the filesystem for hard drives that had much more capacity than an 810 like the Corvus work? All of my files and disks were originally from an 810 using DOS 2.0, btw. Cheers

Love your site, by the way!

I do, and the 1050 doesn't read them. 😞

I have been reading old posts about recovering data and/or archiving old floppies and sometimes the suggestion is not to make the floppies any worse by trying to keep reading them in an 810 or 1050 and instead just send them off to someone who can kryoflux (or similar) them. I have a set maybe 10-12 from my youth that I would like to recover the files off of. I think some are typed in programs, some may have term papers for class...I really don't know what all was on them. Are there folks here that do this or is it a commercial service? How does one find them and go about this or is it something that has to be done on my own for a small job like this by buying the device, a floppy drive, etc.. and learning the software? I've read the wiki page on kryoflux and their website but it isn't clear to me what the success rate is, what the actual recovery dump is (ATR?), etc...can someone shed some light on all of this for me? Cheers

Right. The truth is I don't really want to do much to the 800XL except the composite mod. @SIO2 sort of guilted me into the idea 🤪. The 600XL is on the shelf for now until I can either find a working machine to swap parts with or I may donate it to one of these youtubers that do repairs.

I haven't used it very much as it has a few issues of it's own but nothing like the 600XL. The biggest hurdle is the chips are not socketed. I've wanted to do the composite mod on it anyway so it might be a good time to do that mod and put those chips in sockets so that I can test on the 600.

Whoa this sounds like it's going to be quite the project to get running again! Before I get too deep into it though I keep wondering about the (what looks like) janky memory upgrade. I feel like I should be starting from a known good point and going from there.. Should I downgrade the thing to 16k and see what happens? I don't have any documentation on this upgrade and no one commented on it here either way so I can't tell if it is a common thing or not.. PS Thanks for all the helpful information on this!

Also I tried again a few more times and got this. I wasn't recording so it is a picture.

Here goes, hope this video loads. Now it is black mostly but occasionally blue then black. I think I am making it worse! LOL IMG_7174.MOV

No but I only popped it in, turned it on to see if it worked, then shut it off. This afternoon the unit just gives a blue screen when I turn it on. No, I did not take any chips out and put them in backwards, in fact I didn't take any out. The unit came on and booted to BASIC earlier after I closed it all up. I don't have another 600 to swap parts with in order to troubleshoot so this goes on a shelf for now until I find a working one, or, as someone suggested, a donation to Adrien's basement. Boooooo 😕 Everything I buy lately is a dud! I could have worse problems. 🤪

It isn't only after the line is typed, it's can be either after or while typing a command.

Well reseating them didn't help. I got it back together and powered up. It went about 2-3 minutes typing different commands and then started typing a short BASIC program. Hit RETURN on a line and bzzt...locked up.

So there was no continuity between the 2 jumpers' solder connections. And there is continuity between the ends of each individual jumper. Pressing down on the chips was interesting. Most felt solid but there was one IC, marked CO60472, that had a definite "shoonk" sound and movement downward when I pressed on it. I will leave the case open for now while waiting to hear back from group as to whether I need to do anything else inside the machine.

I haven't connected the Fujinet; I got bummed out when I powered it on for the first time and it kept locking up. I tried Star Raiders but only for a few seconds. There doesn't seem to be a pattern to it. I typed in that entire sample 600XL program from the owner's guide and then RUN, and then it froze up. Then I restarted it, started typing the same program back in, never getting to the end of the first line when it froze at that point. Then I restarted, tried just typing in "GRAPHICS 11" and it froze when I hit "RETURN". The only other cart I have is Defender.

I understood, but phrased it poorly. 😀I will check all of those.Thanks!

So, checking for continuity between those two?

Ok I posted pictures, I'll lift and rseat.

Ok I am not sure what I'm looking at but I assume the mod is the chips with the jumpers soldered onto the pins..hope these are clear enough to see what you need.
