Floppy Drives with TrumpMini3 Woes

[t0nyt]

Oddly the Frogger game published in QL World would not work on the original Trump Card, even after RES_128.

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.

Older (floppy) drives have had jumpers or micro switches, with which it was possible, to select the driver number (1 to 4/0 to 3) on a Shugart Bus. So no twisting of the cable was needed.

No, unfortunately - it might have beenm v1.27 or v1.28

Have found the memory reset problem

The MT3 works the same as Trump 1 768k when its configured with the full 768k extra RAM (could of sworn I tested that, maybe had the jumpers wrong)

It’s only when its configured with only 512kb of extra RAM that the MT3 vanishes when reset to a different total memory

Am now wondering if there maybe a software solution to this with the reset utility, probably not though

Many thanks
Tony

Can you indicate me the exact configuration do you have?
Including versions of gals and Roms, PCB (perhaps a picture) and jumpers?

There were some develop of each of this elements, and first I need to clarify what are you using.

I purchased this already assembled, so can't tell you the GAL version

I'm happy to program a new GAL to try if you can tell me which file to use please?

I've tried ROM 1.20, 2.17c, 2.18 (obviously 2.18 and later doesn't load the floppy stuff after a res_128)

EDIT: Sorry, it was 2.19 I tried not 2.18

Many thanks
