  2. IIsi Sony PSU cap list

    Done one yersterday, the ones that goes bad are the 2200 µf /16 volt (4 of them) the 220 µf and both smd in the small board. The ones in the primary side are ok most of the time. And yes those are bad leakers.
  3. Repair question: 1.4mb superdrive

    Another possibly problem is the eject motor not working properly and avoiding the head lowering down.
  4. Terminating Jaz internal drive

    I have been given a pair of internal Jaz drives. No information found online, is there a way to terminate those drives ? Found a way to change the SCSI ID, but no way to terminate.
  5. Building the fastest Power Mac 9600

    Serious workstation you have going on there. Getting a bit more technical than I desire to understand, but nice job on the chips swapping. Would be awesome having the only upgrade of its kind if you can get the cache working!
  6. Nobody has images of the original media from Apple?
  7. eMac saved from an e-recycling bin

    I think anything single core is unusable on the net anymore. And try running Firefox with a dozen tabs open with 4gb or less RAM.
  8. IIsi Sony PSU cap list

    Lol. I just ended up taking apart my PSU to get the values. Once I actually remove the caps and can see the markings on the board better, I will make a full cap list for this PSU.
  9. Does anyone have a Mac286 Manual?

    If you are using DOS 6 run MSD and see if the FPU is detected or not.
  10. Well darn. Too bad it wasn't a simple speed problem. Digikey still sells new cache chips, 250MHZ, 1MB, for about $14, IIRC. I mention in case you want to try non-salvaged chips. I don't know but am pretty sure the PLD is there to kick the bus req/grant lines at the right time. The six slot machines had a problem with G4 processors. Newertech identified the problem and developed a fix while everyone else (except XLR8) were still drooling. Then Newertech promptly went out of business. Sonnet hired some of Newertech's brains, which was the first smart thing they did; Sonnet products were always inferior and less compatible, and shortly after that Sonnet's G4 card for PCI PowerMacs came out. One of the Newertech guys (or was it XLR8?) explained the problem in detail and it had something to do with bad bus requests or grants or behavior from the second Bandit, which was fixable by watching the bus logic and stomping on a signal at the right time. Soooo, long way of saying the pld is probably there to watch and manage those signals. I posted the CPU slot printout in the Wiki here, so if you really want you could trace the pins and see if they're connected to BG BR and I think there's a retry or busy signal too. BTW, brain fart earlier. The Ebay link in my previous post is for single CPU MDD cards, not dual. Apologies.
  11. Already tried that and cache won't kick in either. Have been going as low as the original 700MHz. Makes me wonder if the CPU is having issues. Going to try even another one. Cache ratio is set in software once the driver loads. Not totally sure what Sonnet has going on with that small PLD on there and if they used different firmware on there for different CPUs. Original CPU was a 7451, new one is a 7455B. The 800 and 1GHz boards coming directly from Sonnet should have 7455A. This should not do any difference I would say though, as I have been replacing 7450s with 7455Bs before and caches kept working... unless Sonnet is doing some kind of magic again here.
  12. Interware Booster 68040/40mhz

    I just realised that I placed in incorrect position - needs to be moved to LC/ColourClassic section - Admin could you move please? Cheers AP
  13. Good afternoon all, Has anyone fitted an Interware Booster CL40-40 in LC/Colour Classic or macs with PDS slots? If so, how did you go with it? Specs - 68040 40mhz with cache card attached. (photo is showing 33mhz, I have 40mhz on its way from Japan) Cheers AP
  14. IIsi Sony PSU cap list

    those PSUs are terrible.... Cheers AP
  15. Conquests seemed the best fit for this post so here goes... About 2007 when I started my vintage Mac collection with my first SE/30, I needed a way to get files fetched from the interwebs to the Mac form a PC-based home office . I found my way to using Netatalk on Mandrake then later on Mandriva Linux distros. Netatelk provided the ability for Mac running Systems 6-9 to connect to the PC running Linux. It is similar to Services for Macintosh available in Windows Servers all the way back to NT Server 3.51. The vintage Macs went into storage as family and house projects took priority. In 2018, time allowed me to get the old Macs out of storage... Now I had a slightly different networking problem as my home office is all current-era iMac and MBPs. I posted here about getting Netatalk going on a Lubuntu Virutal Machine running in VMware Fusion on my MacBook Pro. That article on Applefool is a fantastic guide. So all is good being able to network SE/30s and IIsi directly to the MBP. When running System 9.2.2, the G4 QuickSilver also connects via Netatalk. What also was sitting in the office were my 2 old PCs. One of them is my Museum box that boots to many OSs on 2 drives toggled with the ASUS P2BS BIOS: SCSI Drive (partitions toggled by PowerQuest BootMagic) Partition 1: (OSs toggled with the NT 4.0 boot loader) DOS 6.22 Windows for Workgroups 3.11 Windows NT Workstation 3.51 Windows NT Workstation 4.0 Partition 2: Windows 95 Partition 3: OS/2 Warp 4 Partition 4: Windows Millennium Edition IDE Drive (partitions toggled by the Win 2K boot loader) Partition 1: Windows NT Server 3.51 Windows NT Server 4.0 Partition 2: Windows 98 SE BEOS Personal Edition with loads from Win 98 SE Partition 3: Windows 2000 Partition 4: BEOS v 5.0 that boots from a 3.5 boot disk The drives in this machine were pretty old as this PC was acquired in 1998. I replaced both drives with E-Disk SSDs that I scored from eBay. So now the drives and OSs are all working and all of them (except for BEOS) could mount shares on my second PC running Win XP. The next thing I wanted to solve was being able to connect the PC OSs directly to the Lubuntu VM. I knew that Samba could likely do this and after some digging I finally got this working. Here is my post on the Ubuntu forum. Now from my MBP in can connect every old OS that I own directly to the laptop via the Lubuntu VM. When the G4 QuickSilver boots to 10.2.8, it connects to the Samba share as does the MBP. I gave my propellor beanie 3 spins after I got this sorted.
  16. Fitting a SCSI2SD in a 68k Mac

    Ah, good to hear. Do keep us posted with the PCI SCSI implementation performance.
  17. Fitting a SCSI2SD in a 68k Mac

    The good news is the v6 runs great already on the internal bus. It's certainly acceptable. And writes are definitely faster than v5 in practice. However reads and boot time are about the same between the v5 and v6 in the same 7500.
  18. Fitting a SCSI2SD in a 68k Mac

    It will be interesting to see how the v6 performs in the 7500. On a IIfx, I was receiving 1598 KB/sec on the v6, and 1200 KB/sec with the v5. But, pop the v6 onto a Jackhammer, and I was getting 6054 KB/sec. But VERY nice to have 0.0ms average seek time and 2.3ms average access time. Note however, that there is a known issue with v6 and write performance. I've conversed a bit with Micheal, and he believes at writes after 65536 bytes, the SCSI2SD is falling back to single-sector transfers. This will limit the sustained write speed, but only on files larger than 65536 bytes. He's currently working the issue and hopes for a fix soon.
  19. Fitting a SCSI2SD in a 68k Mac

    AP, You are most likely correct regarding speed. Things rarely run at their max, so I'm hoping a 40MB scsi card opens things up. If not I'm happy to spend 15 bucks documenting that it didn't help lol. For no reason in particular I trust the scsi2sd to actually carry that speed more than the mac. I know for example the external bus is 5mb not 10 on the powermac. So I doubt the internal performance of the scsi bus and it may be a bottleneck. Like you say though probably not a big one given the scsi2sd max speed.
  20. Fitting a SCSI2SD in a 68k Mac

    It wont be much of improvement, correct me wrong it has internal 10mbs SCSI, the SCSI2SD v6 is also 10mbs as well? Cheers AP
  21. Mac SE/SE/30 Ethernet Card Recreation

    Yep, each NuBus slot on has a four-bit slot identifier at the hardware level and each Slot's hooked up to the proper Interrupt line for that ID, IIRC. PDS is a bit different, but it's still the Slot itself in the LC & LCII that's hardcoded, being connected to /STOTIRQ.E only. The LCIII slot extension added (unsupported of course) /STOTIRQ.C and /STOTIRQ.D as in my diagram above. SE/30 and IIsi PDS would be the only configurable multiple card setups I know of. The driver works through Slot Manager which handles decoding, I don't think the PDS card's registers care how they're filled or where they're dumped back into the system, but I could very well be mistaken. Driver/ToolBox/Slot Manager do the address line hokey-pokey and the NIC is just a marionette AFAIK. Which isn't all that much in this instance BTW. Somebody familiar with Drivers/ToolBox/Slot Manager from the Inside Macintosh angle needs to join in here. I just putz around with diagrammed blocks of hardware like they're miscellaneous bits and pieces from a box of borken bar puzzles for fun.
  22. Fitting a SCSI2SD in a 68k Mac

    I use that same enclosure for the virtual zip drive setup I described previously in the thread. It is handy, but the card is somewhat hard to change while the scsi2sd is in the case. A small cut in the case might make it easier to get adult sized fingers in there. I ordered a PCI SCSI card, to see if the v6 scsi2sd can perform any better in my power macintosh 7500. I'm curious to see the result or improvement, if any, over the internal scsi bus.
  23. How to make GS/OS boot disks?

    RetroRider: I have located Disk Copy 4.2 images of all GS/OS 6.0.1 install disks and made a zip file. Send me an email (see my address in sig) and I will send it to you.
  24. Check the 1710 manual for symptoms; you know it’s trying to die when each time you turn it on the convergence is out, or the picture is overscan/bowed in, turning it on and off repeatedlyj fixes the issues. Then the above happens more and more frequently and you know the CRT board is hosed.
  25. I'm looking for the settings for a 3 pin jumper next to the 80287 math co-processor socket. It is labeled J4. My guess is it enables the co-processor. I have a 80287 in mine but I'm not sure how to tell if it is being recognized.
