FPGA replacment for the ZX8301 ULA and more

So it must have been only from Super Gold Card then. Part of the QDOS Official Secrets Act again.

$A1 is dec. 32 on a Super Gold Card in QDOS (JS ROM), indicating 68020 processor. $A7 is 0

I was obviously wrong about this, but I distinctly remember Stuart Honeyball telling me about this when I asked if there was a way to detect different processors etc. before SMSQE came along.

Very sorry. I will never bother answering questions again.

Please don't be sorry, Dilwyn. Thanks to you and Tobias, I have learned something interesting. Also you have drawn attention to an important issue.
In my opinion, the best would be a little program which can run under all operatings systems and does not permanently occupy memory, in case of being run on a 128 KB QL.

Shame on me, the Q68 does not provide a direct identification in hardware, so some indirect check would be needed. E.g. the presence of the high resolution timer is unique.

Hi,

On the Q68, the SMSQ/E MACHINE function returns 18, so if SMSQ/E is used all is identified.

Minerva4Q68, like Minerva and other QDOS variants do not have a MACHINE extension, but there is a programme on the QL Homepage that can do this, whether this will help with identification of the version of QL hardware is unsure.

Maybe the QIMSI firmware, would have a function defined to return the version of QIMSI or QL-SD.

It's actually very easy to add this, I will put it on my to-do list.

Maybe the QIMSI firmware, would have a function defined to return the version of QIMSI or QL-SD.

AFAIK currently the only way is to test the ROM signon message at $C00A.

The QIMSI register QL_SND_WRITE always returns $51. Not perfect as a magic number, but at least independent from the ROM. I think we should go back on topic though.

WHICH MACHINE AM I RUNNING ON?


...


630 =12,13: PRINT"Super Gold Card"
640 =16,17: PRINT"Falcon"
650 =17,18: PRINT"Q40"
655 =20,21: PRINT"SMSQmulator"
660 =24,25: PRINT"Atari TT 030"
670 =28,29: PRINT"QXL"
680 =30,31: PRINT"QPC"
690 =REMAINDER : PRINT"Unknown"
700 END SELect
710 IF machine_type && 1 : PRINT"Hermes or Blitter installed"

Btw, Q-emuLator uses machine ID 26 (I sent a SMSQ/e change for this to Wolfgang a couple of years ago)

HI According to SMSQ/E Reference Manual, the MACHINE types are:

0: for all ordinary ST's without realtime-clock.
2: for Mega ST or ST's with realtime clock.
4: for Stacy.
6: for ordinary STE.
8: for Mega STE.
10: for GoldCard.
12: for SuperGoldCard.
16: for the Falcon 030.
17: for the Q40/Q60.
20: for SMSQmulator.
24: for the TT.
28: for the QXL.
30: for QPC

There seems an ommission on the Q68 and Q-emuLator

18: for Q68
26: for Q-emuLator

I will ask Wolfgang to update this.

Also the SBASIC/SuperBASIC Reference Manual Online version seems very out of date.

Hi Derek.

I'll attempt to update the online manual soon. Thanks for the info.

Cheers,
Norm.

I'll attempt to update the online manual soon. Thanks for the info.

EDIT. To correct the info.

Oh hum, I tried an update but the build failed as the OAuth on my GitHub hadn't been allowed access from ReadTheDocs. I fixed that and the build failed with another problem that is supposed to have been fixed. I've raised an issue.

Cheers,
Norm.

[NormanDunbar]

This is now fixed. See main thread at viewtopic.php?p=53323#p53323 for details.

Cheers,
Norm.
