Zemu

I tried running Zemu in RT11 v5.3 in SIMH. It starts and asks for a game file. I entered ZORK1.DAT (from a zork1.zip I once downloaded). The ZORK1.DAT is 180 blocks. Zemu aborts after some 10 [ZALLOC] messages: [ZALLOC]: Insufficient memory] We didn't get memory for dynamic data. Aborting... [Entered ZEXIT] [INPEND: timer cancelled] and then I am back at the RT-11 dot prompt. Next I tried ".VBGEXE ZEMU". After a [ZINIT], three [ZALLOC] and one more [ZINIT] line, Zemu prints "ZEMU/RT X00.19" but then I return to the RT-11 prompt! The last attempt was starting VBGEXE.SAV without a program on the startline. VBGEXE asks for a program, and I entered ZEMU.SAV. Now soem 20+ [ZALLOC] lines are printed, the last lines are the following: [GETSLN: returning 24. lines] [GETSCL: returning 80. columns] [GETSTP: returning terminal type 3.] [PUTTXT: Address = 066736, count = 14. characters] <[?7l<[2J,=<[r ?MON-F-Trap to 4 101566 . So, it is getting further. The "<" is actually a small arrow. I guess these are control sequences for a VTxxx terminal? Or

as the zork1.zip file contained a zork1.dat, an .exe and a Nnansi.com file (thus PC stuff). Perhaps this ZORK.DAT file is not correct ...? Or does the ZEMU.SAV need somethignfrom the RT-11 environment? Zane has build Zemu in RT-11 V5.7, and my version is 5.3 ...
