Hmm, I do not know any TK2 ROM without TK2_EXT, but I may be wrong. The better way seems (for me) to put it all together under QL with RPM or EPROM Manager, as these take care of the right boundaries,dilwyn wrote:Also depends on what TK2 image it was. Some of the 16K plug in EPROMs didn't have a TK2_EXT command (although most did, to enforce the TK2 definitions if required later). The extensions in those versions were just linked in at startup and that was that available to use without any action on your part. Try using one of the TK2 extensions, if it works, youll know that was the case. TBH, very unlikely, but one of those quick things to test before wasting time on something which takes much longer. If this was the case, you'd see a startup message top of the screen before pressing F1/F2 to start the QL.
In the old days, I have done this always "by hand", say, RESPR e.g. 32k, then LBYTES the e.g. SQB ROM into the first, then TK2 into first+16k, then SBYTES this as 32k and burn the EPROM. This has worked everytime.
