  1. I’ve noticed that the MemoryX website has been down for the last month. Have they went out of business?
  2. Hello, Has anyone found a source for the 68 pin 256k VRAM SIMM apple p/n 661-0722? The SIMM is used to upgrade the video ram from 256k to 512k. Thank you, Rick
  3. Hello, I want to upgrade the memory in my SE/30. Has anyone purchased 16MB SIMMs from the company Memory(X) ? thanks Rick
  4. I recall from my Apple II days that several programs, or firmware allowed you to inspect the contents of memory. Does that capability exist for the Macintosh 68k family? thank you, Rick
  5. A viewer of my YouTube channel recently asked me about a Sad Mac Error code that he is seeing on his Macintosh 128K: 047A80 It would seem to be RAM related as per this: To identify the individual bad chips, we use this... Unless I am in error, the 7A80 part would seem to indicate 6 bad chips at the following locations: 1000+2000+4000=7000, so: G9, G10 & G11 0800+0200=0A00, so: G6 & G8 0080 = F12 Strangely, Mouser doesn't have replacement chips but JAMECO does. As you can see on
  6. Hi all, having problems installing rominator 2 and owc memory. tried installing both separately without sucess as i just get a grey corrupt screen on boot up and funny sound. I cleaned up the board and connectors with contact cleaner as i thought maybe my se/30 is afterall 27+ Years old and may not have had the simms installed/removed in that time but still no look, put the old rom and ram back in and it worked straight away. Now i have a new 1gb hdd with Mac os 7.5.5 installed and wasn’t sure if that was causing the rominator from working but as i cant even get a boot up screen that
  7. Hi guys, I just installed 16GB of PC2 6400 RAM into a Late 2005 G5 (11,2) The memory is showing as PC2-3200U-288 in the system info. QUESTION 1: Would I benefit from installing actual PC2 4200 RAM into the machine? (Which is the specified maximum speed for the machine) GeekBench2 in 32 bit mode gives a benchmark of 3370 which seems to be OK for this class of machine. QUESTION 2: Would using non ECC vs ECC make a notable difference? Thank you guys.
  8. I saved an SE/30 with 64MB of RAM! Since I’m not used to this amount what is the normal boot-time? It takes approximately 50 seconds for the ”happy-mac” icon to do it’s thing in 32 bit mode (Mode 32 7.5), is this normal? Is it time for a re-cap? /K
  9. To All: Hi, I'm Gerry. I'm new here because I come from the Apple II world. I belong (for some 30 years) to the still active OAC (Original Apple Corps) Users Group here in Santa Monica Ca. With much of the group we discuss Macs since that's what people want help with but we also talk about Apple IIs and PCs. I have a couple of Apple IIgs-es, and recently an Apple IIe card for the classic LC series Mac. I bought an LC 475 and added 128 MBs of system RAM and upped the display RAM to 1 MB. So far everything works great. Then, in an effort to replace the noisy boot hard drive, I replace
  10. Hi, m68k users! I've been using bbraun's djMEMC fix in the NetBSD kernel to support 260 megs in a Quadra 610. However, sometime between last summer and now I've noticed that when I'm booted in to Mac OS 8.1, the Quadra is showing 132 megs whereas it was definitely showing 68 megs in the past. This isn't after warm-restarting from NetBSD or anything like that (I think bbraun mentions or implies that the ROM memory routines run on all boots, so changing-then-rebooting to get more memory isn't an option). Has anyone else seen 132 megs on a Quadra or Centris 610 without modifications?
  11. In Apple's official documentation and other documentation on the Internet say that the Xserve G5, which has eight memory slots, can take up to 16 gigs using ECC memory. In the past I've bought a couple of 2 gig ECC DDR-3200 DIMMs, but they didn't work. Considering how some regular DDR DIMMs don't work in Macs, I assumed it was the DIMMs. Does anyone know what specific kind or of a specific place where one can get 2 gig ECC DIMMs which will work? If I find working ones, I am also inclined to test one in a PowerPC Mac mini. I always thought that if the mini had 2 gigs, it'd have been perfec
