    HDI-20 disassembly help.

    I got two of these HDI-20 disk drives and both have issues (one doesn't let disks in and the other seems bereft of life). There's no screws anywhere on these so how the hell do you open one up? I assume you have to pry it open but I fear I may break some clips if I do some guess work! Anyone have experience opening into these that can help?

    Ah! That's the one, you are a legend my friend, thank you! Edit: So simple once you know! Just dismantled one and got one up and running again, thanks again. Now I got to find my NOS disks and make some software for my PB machines.

    Help identifying Lapis PDS card.

    I get you, thanks for the info.
  5. As per title, does anyone have any information on this card? I was going to list it up for sale but I got no idea what it is exactly! I assume some kind of mono video card (duel or full page display?). Does anyone have info on this? Better yet are the drivers still available? Regardless, I'm fairly sure it isn't worth much but I'm trying to declutter so it needs to go...
  6. Yup, that remote is for the Mac's that had that little rectangular black IR receiver at the front. Some 'all in one' 5000 series machines had that along with the 6000 series and the 630. Always useful.

    That looks very similar to mine. That 24 looks awesome though! Do you know if there's a way for this to work on a standard 15-pin D-sub? Is it definitely a ColorServer and not part of the Pivot/Page display range?

    Performa 630 DOS issues.

    Il give your suggestions a go when I drag it out off the back-burner. I must admit, the thought of doing 3 partitions is kinda messy IMHO. I think I'd prefer to stick with 2 (as that's ideal for me with DOS taking up half of the space). What is really like to find out is how to get the damn CD drive support in DOS!

    Performa 630 DOS issues.

    Hi again chaps. I've drawn a blank on this one so I figured you guys are the best people to turn to. So I have a couple of issues with my 630 that have cropped up since I've upgraded the HD to an 8GB one (2x 4GB partitions). First one is that it crashes a few seconds after selecting "Shut Down". Not sure what might be causing this, it was shutting down perfectly fine before. Second is to do with mapping a hard drive to the DOS card. When selecting "New Drive File" and making a file for the DOS HD (doesn't seem to make a difference what size I make it) and selecting "Initialize Drive File" and saving it on my System 7 booting Partition then going to "Create", it goes to "Preparing drive file" progress window and hangs after about 5%. Sometimes it will just produce a blank white box after about 10-20 seconds, sometimes the "watch" mouse pointer disappears and sometimes it produces a pale yellow window with a 'picture frame' style outlines around the boarder. Very bizarre. Anyone have any thoughts to where I should look? I know the hardware is working fine, I can boot and enter the DOS mode fine, just can't seem to make a drive file.

    Not at all, your input, like everyone's is always valuable. I'm in the same boat, like most of us working class. Sadly these have to take priority over our unhealthy obsession of old/vintage silicone! No doubt I'll necro this again sometime and see if we can finally solve this mystery!

    Are these computers worth getting?

    Grab all of them. They will all be useful in some form or another. The 550 especially, I'd kill for one of those, they are hen's teeth rare in the UK.

    Thanks for that and sorry for the lateness of my reply. I've shelved the machine for now. It sounds like you have exactly the same issue as me. I wonder if Vogons might be more helpful for this. It might generate some interesting discussions at the very least. In the mean time, please do post here or message me if you get any success with CD-ROM support through DOS!

    Performa 630 DOS issues.

    I did actually think this, I'm not sure there's a way I can just format the primary booting partition without destroying the DOS file drive partition. There might be a way to downgrade but I can see OS 8.1 putting up a fight to achieve this. If you could take a picture of your config and autoexec that would give me some insight. There's probably loads I can edit and/or delete, but is not so easy to decipher what's actually useful being as this isn't just a plain ole x86 PC. I've made some edits with moderate success and have plenty of experience with autoexec and config. There's plenty of room for improvement still and much as I want to change the order of the commands and other stuff around to save conventional memory, doing this seems to just break everything. So unless someone has alot of experience with these 'hybrid' systems and/or has managed to fine-tune their setup, I'm stuck with them looking fairly messy. Yeah I did all that, the posting even detects the drive fine (drive E:). But I might have to look at that drive sharing. Never thought about that! Will keep you posted. . .

    Performa 630 DOS issues.

    Well after installing to 8.1, I can finally make the DOS drives on the secondary partition with success. Not sure what the issue was before but I'm more than happy now so thanks for the advice on updating the OS. Everything seems to work great, albeit, slightly slower than 7.5.5 but I can live with that (hope to get it overclocked in time anyway!). One issue I currently have is the CD drive doesn't seem to work on the DOS side. I'm fairly sure there's an issue with my config.sys or possibly autoexec.bat. Does anyone here have one of these with working CD support who can take pictures of their autoexec and config info?

    lc475 video problem

    Sounds to me like you're on to something. I should have suggested using IPA on the slot or SIMM too! Oh well. I wonder if that the slot may have took a knock or damaged some other way while there was a SIMM installed (dropped possibly?). Are the solder pads all making connection? If you need a new slot, you may have to pilfer one from a broken LC (or similar), I can't imagine these being easy to come by being as they're not the usual 30 or 72 pin types.
  16. tokyoracer

    Performa 630 DOS issues.

    Ah I see. Il probably just make a file the size of the second partition in that case. 8.1 seems to have installed okay, will let you know of the PC side of things are working.

    Burning CDs for Performa 637CD

    What timing, I've literally just been doing this for my 630. So in answering your question, it really depends what you intend on what kind of CDs you want to make, the burner and (half decent quality) CD-R's shouldn't matter too much (avoid RW's though!). With ISO files and most other disc images, you should be able to burn them on any machine and/or configuration that can handle the files (for example, I use PowerISO for Windows). If you want to drag and drop files and use CDs like a thumb drive (that once burned you can't re-write obviously), then that's more tricky. To achieve this you need an OS that can handle plain old HFS (not HFS+). The last OS to support that legacy is Leopard, and if you don't have a good DL burner, it's a bit of a pain to install (possibly impossible on most modern Mac's too). I managed to get Leopard on my Mac Pro 3, 1. From personal experience, my external 600 drive hates them, and the 300 / 600 internal ones seem to mostly read them ok but not always 100% successfully, often having a bit of 'data garbage' that you never intended to add. There's loads of tutorials on how to do this. Il link you to them of nobody else does in the next 24 hours, but right now it's half 3 in the morning and I'm about to pass out. One thing I will say is I strongly recommend that you burn at the slowest speed possible.

    lc475 video problem

    Ok stupid suggestions and probably obvious but here goes. Have you checked for polarity and made sure the cap ratings match what you replaced and that they're definitely making good contact? Did you replace them with a different kinds of caps? I know solid state types are preferred and people often boast about replacing electrolytic for ceramics but they can cause issues. I also assume the board was cleaned before and after the work was done? Assuming all this is in order, one more stupid question; have you tried it on a different monitor? It looks like you're using an original Mac monitor but if not, check the VGA adapter too just to rule that out.

    Performa 630 DOS issues.

    Sorry to double-post, just a quick question for the gurus. The OS8 disk tools has an option to partition a drive as a ProDOS format, could the DOS hardware access that partition if it is formatted that way?

    Performa 630 DOS issues.

    Brilliant, thanks. I will probably let someone more talented loose on it since it does look finicky. In the mean time, I will try 8.1 and see what that goes, will keep you guys posted.

    Performa 630 DOS issues.

    The OS 7.5 CD install complained about the drive size being too big, but it seemed to no issues with the 8GB drive being split into 2x 4GB partitions, only after updating to 7.5.5 and adding some software did it start to cause the freezing shut down issues. Still no idea what's going on about the freezing of trying to create a PC drive file though. I'd love to take this thing upto 40MHz, trouble is I'm not a great soldering expert. I have a half decent iron but I need experience which I have no time to achieve right now. Especially anything SMD. Of I could find someone who could do the work I might look into it. With that performance boost, it might make 8.1 a more smooth experience. Is there any tutorials for overclocking the 630?

    Performa 630 DOS issues.

    Well I'm running 7.5.5. I generally want to avoid 8.1 as System 7 is notably more spritely and 7.6.1 doesn't have quite the legacy support 7.5.5 has. My old HD has 7.5.5 too and doesn't exhibit these kinds of issues. However, that idea of re-inserting the main board is a good one, I'm not sure why O didn't think of trying that. Might get the IPA out for it too, certainly can't hurt. It's pretty loaded up (full 040, DOS, Comm card, TV/AV stuff, etc so there's plenty to go wrong! I will try that now. . .

    Bad caps leading to slow performance ?

    Dumb question here, what machine is it? I know my LC was woefully slow on System 7.1. Didn't take much use or software to drag it down more and more as I used it. I downgraded it to 6.0.8 and it was positively spritely in comparison. But yes if you see "visible damage", and if you got the means and/or skill to repair it, don't waste any time. Atleast wash the PCB thoroughly and carefully.

    Help identifying Lapis PDS card.

    I guess this card will remain a mystery. . . But if anyone does find out some info on this particular card please do let me know. In the mean time I suppose I will list it up for sale as it is. As said, it could always be used as an FPU card! Thanks for the help anyways especially omidemo, you are probably onto something there. Pity mine doesn't use a standard 15-pin output (it's a 9-pin D-sub, not 8 as I made a typo).

    Help identifying Lapis PDS card.

    10029-1F? No. All my LC's have network cards with FPU's so it isn't really any more useful to me. That said, it's possible that might be what it is. But would it be a colour card? It has an 8-pin D-sub on the rear, not the usual standard 15-pin D-sub so I assumed it was probably mono.
