RN (actually RRN) here chokes sometimes when I try to follow up to your posts, and I have never experienced that problem before. The error is an interp buffer overflow, and it looks like the References: line is the problem. The following is the References line for your post as I saw it here.] References: <1991May5.124008.24559@sugar.hackercorp.com> <1991May6.113553.8351@sugar.hackercorp.com> <1991May7.055159.1474@cunixf.cc.columbia.edu> <3409.tnews@templar.actrix.gen.nz> <48758@ut-em ^This looks like the problem... RRN probably searches for a closing greater-than and doesn't find one before overflowing its buffer. melling@cs.psu.edu (Michael D Mellinger) writes: In article <48758@ut-emx.uucp> greg@ccwf.cc.utexas.edu (Greg Harp) writes: You forgot to mention the little detail that you have to buy four at a time to expand a 32-bit machine... Actually, I didn't know that. Well, unless there is some fancy memory controlling going on (which would also be slower) you have to expand the memory in 32 bit wide chunks. SIMMs are only 8 bits wide (unless you're expanding a PeeCee, where they use 9 bit wide modules). Since you brought up memory speeds, I ought to mention that I saw some discussion on comp.sys.next a while back about the NeXT using 100ns RAMs. Is that true? Is it just NeXT saving some $$$ or does memory faster than that have any benefits on the NeXT? I believe the discussion was about what type of RAMs to use when adding memory, but it was a while back... No, 100ns RAM is all that is required, and faster memory does not increase the speed of the NeXT. Hmmm... How many waits does the memory require? I'm really amazed because I've seen 80ns RAMs make a big difference in 030 boxes. The recommended ZIPs for the A3000 are 70ns, with a static column mode that makes the access time much faster (45ns?) when you access the same memory column. BTW, the going price for these is about $28 a module, and you need eight at a time making the price $224 for four megs. At that price I've basically considered it part of the purchase price for when I buy my 3000. Why on Earth would NeXT use such slow memory? I'm literally shocked...
