New topic about memory, was "Off topic, but not by far"

So after looking around, I dediced on the Brother Hl-1440 ($190 after tax). I got a new one from Office Max, not the refurbished one from TigerDirect that I posted the link to in the original message. I really didn't need all the power of the LaserJet 4. In a given month, I will probably print 300-500 sheets, so having a workhorse would be nice, but overkill. The Brother seems to work really well, does all I need. I do have a question about memory. It has a 72 pin SIMM slot for upgrades, and the manual says it requires 60-73nS access time IIRC. I have some old 72 pins sitting around, so I found the most recent of them and tried to find some specs on the chips. One had 1 Meg chips with what looked like 16mS time (HY5118160 chips). Is that figure right? The only other one I had uses KM48C2100AJ-7 chips by SEC. The labeling on the chip looks like, SEC KOREA 516Y M48c2100AJ-7 I couldn't find any data on this, if anyone knows where to find the datasheet or even just has the figures, I'd really appreciate it. The SIMM is manufactured by VISIONTEK (barcode on back is MEMSIM023AAWW) made in 1995, if that helps. I'm assuming this will be too slow as well, but just out of curiousity I put it in. It seems to work fine in the printer, it recgnizes it in its configuration, printer runs at normal speed, but I still took it out. Any thoughts, should it be ok, or probably isn't worth it, etc. Thanks for all the helpful replies, I appreciate it! Steve
