It was the only program where I ever found this issue - any other program worked after RES_128 and still had access to the floppy disks.

Reading the comments above, it looks as though RES_128 has been changed since then?

I would not rely on the RESET commands in Beule Tools - without looking at the source code, who knows what it does compared to the Trump Card RES_128?

Yes, RES_128 was changed in TC v2.18

I 'borrowed" the code from Beule Tools to use in my own toolkit (not sure if I changed much, probably not), but haven't compared it to the TC code

Code: Select all

RESETT   move.w   CA.GTINT,a2
         jsr      (a2)
         subq.w   #1,d3
         bne.s    FULL_RES
         move.w   0(a6,a1.l),d2
         divu     #64,d2
         andi.l   #$FFFF,d2
         mulu     #64,d2
         cmpi.l   #896,d2
         bgt.s    ERROR_BP
         cmpi.l   #128,d2
         blt.s    ERROR_BP
         add.w    #128,d2
         mulu     #1024,d2
         move.l   d2,a4
         trap     #0
         ori.w    #$700,SR
         lea      $C0000,a1
         lea      $10000,a0
         move.w   #$FFF,d0
SHIFT    move.l   (a0)+,(a1)+
         dbf      d0,SHIFT
         jmp      $184
ERROR_BP moveq    #ERR.BP,d0
         rts
FULL_RES TRAP     #0
         reset

I can’t live with Minerva’s incompatibility with lots of old software on my main machine (and spare QL’s are in storage)

So will stick with JS & original Trump card for now and keep the MTC3 for use in a spare QL with Minerva mk2 in the future

Also, if JS+MTC3+Qsound could cause hardware damage as per stated in another thread then probably safest to just swap original Trump & Qsound as needed

Many thanks

Hi Rich,

Can you remember which version of Trump Card Rom that the RES_128 had floppy disk access.
