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...
: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...
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...
- 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...
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...
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...
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...
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...
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...
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...
I have one that fizzes Nicola Tesla stylee (big blue arcs of HV) the sparks come from the triper (next to where the red HT cable is attached) to the scan coil cables, looks great in the dark. Kaput
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...
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...
