Quite right. In transitioning to the A500+, some latter production A500s had rev. 8 boards with ECS (Agnus 8375) when C= were trying to use the remaining old stock of cases and other parts. Consequently, some of the late A500s had odd configs like KS1.3/512K chipram/ECS (see below).

Some early A500+ owners got shafted with odd configs, with C= populating rev. 8 motherboards with, say, KS2.x and 512K chipram + OCS (instead of 1MB chip + ECS!)

Always worth popping the hood on an A500 and checking (just coz it's made by C=, of course!)......you never know what trash 'n' treasure you may find inside a seemingly boring old standard A500!
