> From: Kyle Owen > So the same technique would work on the 11/35, then? Yes, the /35 and /40 are completely identical, except for the number painted on the inlay on the front console. (Well, the /35 was often sold in a BA11-K box, and the /40 in a BA11-F, but that's just physical configuration, and is just a 'usually' - there are /35's in BA11-F's [for sure], and probably /40's in BA11-K's.) Noel I vaguely remember that there was a difference in the front console For the BA11-K and the BA11-F configuration. When standing in front of the console, the two ribbon cables from the front panel are at the right side for a BA11-K box, and on the left side for the BA11-F box. Given the location of the CPU boards in both boxes, that makes sense. I do have an 11/35 in BA11-F box (on the system manual cover this is indicated as the 21“ model). I also have an 11/35 in BA11-K box, so yes, both configs exist(ed). Henk, PA8PDP
