Ed Minchau 63 Posted April 8 4 hours ago, rje said: Banked RAM consists of up to four RAM chips, each with 512K of static RAM, if I understand correctly. Chip 1: Banks 0-63. Always present (required, since Bank 0 is used by the OS). Chip 2: Banks 64-127. Chip 3: Banks 128-191. Chip 4: Banks 192-255. Thus, a test would check one bank as a proxy for each 512K segment (say, banks 65, 129, and 193), and see if it can write/read that bank. I wonder if a 256K static RAM would fit in those spots... horrors... Is 3 RAM chips even going to be an option? My understanding was they'd only be selling 512k, 1M, and 2M variants.

The way I interpreted the FAQ is that all Commander X16s will be sold with 512K; any additional RAM must be added by the user. Quote Share this post Link to post Share on other sites
rje 235 Posted April 8 That's right. The X16 only comes with 512K of the banked RAM. It's socketed so it's easy to add more, and (if I recall right) they're less than $10 apiece. Quote Share this post Link to post Share on other sites
