    Compact Mac CRT compatibility

    The main purpose of these message boards is to be helpful, there is a lot of ppl with useful knowledge. I was unimpressed by the previous remark, I design monitors professionally so for someone to dismiss my technical statement and replace it with a wrong one, well really. :o) I could give...

    Compact Mac CRT compatibility

    :lol: - your mistake, fundamental, do you actually know how the circuit works? It would seem not.Indeed I might choose to swap CRT yokes becuase that's my business, and colour CRTs are very diff from mono, but that was not being disussed here. But to the average guy wanting to do the job, it...

    Compact Mac CRT compatibility

    If this was at my house it would be fun. First check is the CRT part number (Mfr) which are usually long affairs. The easy option is to get an exact replacement. Also check the scan coils, they might have a similar number. I've just looked on my Mac Plus and the numbers are there. Get the same...

    IIfx/CD 5 year tune-up . . .

    - yeh. I was in the computer industry when all this was at its height. We were using AutoCAD v2.1 on DOS AT with coprocessor that wasn't even installed on the motherboard correctly! The big deal was redrawing times in AutoCAD, many systems redrew very slowly, there was the benchmark drawings of...

    Mac+ OS floppy request

    Actually this is an option, rubber gloves that is provided they are suitable. Many people might be home users who just need to make a few adjustments to the yoke, the rubber gloves do add a degree of protection. :) I find as you concentrate on the screen (even with a mirror) and fiddling...

    Mac+ OS floppy request

    Multisyncs can be fun, I would give tutorials to the test guys (post manufacture) showing how they worked and what to look for if they don't work. I think it was a little easier for us tecknight as these were our designs so knew them inside out. Design is fun too, two things stick in my mind...

    Mac+ OS floppy request

    In 1990 I workd for a tech company, we were desiging and building graphic workstations as used in aerospace, serious money ones. One rival was the likes of Sun Sparc workstation and the Mac got mentioned a number of times. I can see now why the Mac IIfx was such a hit, that SuperMac graphics...

    Darn it - just when it all seemed good IIfx boot prob

    The videocard worked fine on the IIfx running OS7.0.1 I was in the process of trying to get a new OS set up and internet access. I've had it running a week now, seemed quite good. I found the SuperMac driver V3 and it all was going quite well, I could access all the screen resolutions, nice...

    Darn it - just when it all seemed good IIfx boot prob

    I wonder, I notice a huge custom chip on the video card is getting very hot also two little chips UJ7 and UK7 on the main board are getting hot too. As a thought I removed the video card and the HD flashed for longer (obviously I have nothing to look at) so I'm wondering if the video card has...

    Darn it - just when it all seemed good IIfx boot prob

    This morning the IIfx was running well :) but 4 hours later when I come to play with it again, bootup problems. I wonder if you guys might have suggestions. Power up, all's well chime, floppy makes a few noises (but won't boot with disk inserted), the HD starts and gets accessed (busy led...

    MIDI performance on a Macintosh Classic, good?

    I know this thread is now somewhat old. I have an Atari ST 1040 with Sequencer One Plus (now free) and that is the tightest to date. It has two issue that get me, one is it sends a bunch of sysex commands when the "stop" key is pressed, which at the time of programming were harmless but it...

    Mac Classic/Performa200 startup fault - suggestions pls

    IT WORKS!! I cleaned the board in alcohol and then replaced all the E.caps, very fiddly and it now works. The cap goo is almost invisible, I only really noticed it in the murk of the clear alcohol, the soldering job is not for the faint hearted it does require very good soldering skills else the...

    Mac+ OS floppy request

    The Ensoniq Mirage used single sided floppies which were a custom 400k which can be read using appropriate software in DOS/Win, again I believe it uses a std WD floppy disk controller chip something like a WD1550. The Mirage is was relased in 1984 The EPS "Classic" was relased 1988 then the...

    Mac+ OS floppy request

    ooh.. we seem to be moving away from the subject of my post - I'm sure there was all sorts of things going off in the computer industry at the time, after all it was ground breaking stuff with huge profit potentals. I like the sound of a "Twiggy Drive" I do wonder if that would have kicked off a...

    IIfx - how to boot from HD and LAN connection Qs

    :) IT WORKS!!! OK here's the solution: I don't know if this is important or not it was just a part of the plan, the new HD is now set to addy 1. I figured the IIfx might be trying to boot from 2 OS, one that I have just installed and the old Performa200 one residing on the Apple 40MB. So I...

    At the moment I now have the new 9GB ( as 2+2+2+2+1GB) HD successfully partitioned using the FWB Software and used the OS7 install disks to install Mac IIfx specific on the first volume, I've now set the drive to SCSI:0 also on the buss I have the 40MB Apple drive still connected which is now...

    What's big and too big, hard drives that is

    Don't we just like success :) as you know I've been trying to format that 10GB Seagate with various tools and now by chance I find Hard DiskTools 2.0.5 by FWB Software lurking on an old drive and as if by magic... it formats the drive!! It does the 2GB limit, so it formats the drive...
