It's just a misunderstanding: "OLD" as "improved mbla000 CLASSIC", "OLD" as "not unreleased"
I corrected my previous post to be clearer

Like a "traditional" 8K (e.g., VIC-1110) or 16K (e.g., VIC-1111) memory expander cartridge? -OGMMarsupial wrote: ↑Thu May 23, 2024 6:27 am the Diagnostic ROM is intended to run on a cart that has memory expansion - I am trying to run it on a non-expanded cart. I am new to VIC20 but most software I tried complained when they required a (missing) memory expansion... but not the diag. It seemingly runs OK until it gets these errors.
Although I am not sure how much I actually helped, you are welcome!Marsupial wrote: ↑Sat May 25, 2024 8:18 am I am currently attempting to add a RAM1 1k expansion to a cart PCB in order to get a working diag. Part of the fun is to make the tools, and I've learnt more about VIC20 architecture trying to make this diag cart than I originally imagined.
Thanks a lot for the help, it really is appreciated!
