    Old nd strange computing hardware
  1. For my Apple Network Server 500/132: 1. The 150 MHz CPU card 2. The 1 MB Level 2 Cache module 3. The Apple Network Server 700 ROM Module 4. One 68 Pin SCSI Interconnection Board (now ALL 5 HD trays will be fed with 72 GB drives!) 5. Two 50 Pin SCSI Interconnection Boards (just for backup somehow) Still looking for some parts though... J
  2. Long time ago since I´ve been here... Anyway, I would like to ask if someone around here has at least some experience with a Kinetics (later "Shiva") FastPath 4 LocalTalk / Ethernet Bridge. Although mine seems to work none of my Macs "finds" it with the Shiva NetManager... Thank You for any reply! J
  3. I have tested my 6100 several times with a G3 upgrade, an older Radius graphics card and the 486 Intel CPU card and I also noticed these differences about the temperature inside the housing - but to me it wasn't the reason for a locking up Mac. In the beginning I've been using the original Quantum hard disk but especially when using this disk along with the G3 upgrade the 6100 showed these lock ups. This didn't happen with the Radius or the 486 card. So I exchanged the original Quantum drive with an IBM Deskstar (in fact I never trusted the old Quantum drives). The lock ups didn't reappear.
  4. A single beep -> could <- mean a wrong or not well seated RAM module. Regarding the screen flashing: try to connect an external display and see what happens. J
  5. Oh, that´s very interesting for me, could You please tell me what kind of card it is? Manufacturer? Modell? J
  6. Could need a second one myself... J
  7. It's a chick magnet, for sure! Maybe because it looks like a "new" old school cell phone or some sort of new designed iPhone ]'> Although I have 5 ROM packs no woman ever asked me about that ]'> J
  8. Congratulations! The more I´m dealing with that box the more I like it - although it´s the far most complicated machine I ever had to deal with. In the meantime I managed to get nearly all software for it, just the Apple distribution fixes and the RAID card software are still missing. While the configuration of AIX itself is quite easy its very difficult to connect it to a network: there is just one Apple PCI NIC that can handle 100 MBps, all the others drop that box to 10 MBps. Besides this I´ve tested more than 30 other PCI cards leaving just two that will work together with that server.
  9. I surely am a user (not only) of old Macs and if possible I repaired nearly every machine I own by myself (besides my G5 that leaked its cooling liquid for killing both CPUs). Again: I never dealt with CRTs before, nor with analogue boards of old Macs and before I´m searching for any good starting point in order to repair my Plus I´m trying to find helpful hints where ever I can. To be honest I´m no super-soldering-master and I´d really hate to blow my Plus just because of re-soldering something that didn´t need it. J
  10. I will ake some photos as soon as possible! Well, some obscure online auction sellers are sometimes manipulating old stuff in order to achieve higher rates. Although not very "popular" it might have been possible that this Mac is a physically downgraded Plus with the faceplate from an "out of order" 512k. Plus Macs are much easier to find nowadays... For example: the small circle of production months stamp. European Macs sometimes bear special markings from some non-Apple companies that tested those machines in operating security aspects - but these markings are missing.
  11. Now after opening both machines it seems pretty clear that my 512k is an upgraded one. The tube and the board beside the tube are definetly from the 512k and so is the front housing; mainboard and backside housing is from that Plus upgrade which also contains the 800k floppy drive but not the extended keyboard. One thing is still a bit strange: while my Plus shows all the signatures on the inside of the beige backside housing the "upgraded" backside housing from my 512k is missing these signatures and is held in black, it also misses any further engravings that my Plus shows but it is defi
  12. Today I' facing a rather unusual Mac which I won within a non-eBay auction. The front housing of that Mac clearly identifies it as the 700th 512k Mac manufactured within the 34th week of 1984 (regarding the aerial number decoder online) - the sticker and the front housing are definetly original meaning a possible "Plus" badging wasn't rubbed off that front housing which normally leaves clearly visible hints when removed. But... The back of the housing is definetly a "Plus" one as it carries a SCSI port (which to my informations is missing within a 512k). I haven't had the chance until
  13. Hello. I'm looking for some info regarding my Plus. Seems to me that mine is facing that video dropout problem: after running for 10 minutes (sometimes less) there is some silent chirping sound and the display loses it's output (while the Plus seems to work). I know that there is some solution mentioned about resoldering some Pin 1 of some connector but I don't have any "in detail" description. Is there any description / documentation out there maybe with some photographs? After reading the georgeous documentation about compact Macs (the difference between Rev A and Rev B boards and else
  14. And my last addition: While reading Your first post all over again I decided to pull out my Portable again to see what else might cause Your spin up and down. As long as Your hard disk spinning doesn´t sound VERY strange (like disk clicking, scratching noises and else) just decide to shut it down and connect the Portable to the power supply for more than at least 6 hours. Try to boot up that box again afterwards. The Portable is very picky about power supply ratings so after some time of no usage (and sometimes even with rebuilt / remade battery) the alltogether power supply of battery, 9
