Any utility capable of reading the disk, i.e. Copy II+
The boot sector has nothing special compared to all other sectors of the disk.

I think I just use the code from Beneath Apple Dos to do a disk read
into memory and disassemble it from there

sorry, I didnt read your next step below - that would be a fast way to read the boot sector.

The ROM code for slot 6 on the IIgs, if not set to your card and after the code is relocated, requires a change at $96FB and not at $96F8

Hi John,
Are you interested in ONLY the Pascal boot sector, or do you plan on disassembling more of the Pascal boot process.
If you search around (Wizardry re-engineered), you will find I started with the boot sector and disassembled most of the run-time Pascal system in my efforts to disassemble and successfully re-engineer versions of Wizardry.
When you write "Apple II Pascal boot", which version of Pascal are you interested in? Also there are a few different run-time versions (based on system memory size if I recall correctly).
I used a version of CopyII+ for most of my sector reading.

wow, I didn't know someone already did most of the work. I'm looking at version 1.1, i have version 1.2 and 1.3 but for now 1.1. I think the later version support larger directory/subdirectory or is that UCSD Pascal 4.0?
Just wondering, but have you traced Apple Pascal boot in scsi environment?

Hi John,
I'm not exactly sure what you mean by "traced Apple Pascal in scsi environment." When I was working on Wizardry IV a few years ago, I was using a Windows computer running AppleWin to examine the Pascal 1.2 boot code.
I mostly worked with Pascal 1.1 and Pascal 1.2. I am not familiar with Pascal 1.5 or II.0.
A long time ago I boot traced Wizardry III to the start of the actual program and have that information in paper form in a box in a closet.
Long after I did that work, I stumbled upon something you might be interested in.
You should search for: Apple 2 Pascal 11 PCodeIntDism.pdf
It is titled: "Apple II Pascal 1.1 P-Code Interpreter 6502 Disassembly"
By: Willi Kusche
When I did the boot tracing for Wizardry IV, it was for Pascal 1.2 and I have notes on that in text format on my current computer.
Tommy

I believe UCSD II.0 on DEC PDP-11 became the base for Apple Pascal and everyone else. I have Randy Hyde Apple Pascal disassembly book, did some of the tracing for the floating back in the late 80s. I often look at the PDP-11 code for the P-code interp, it's a very clean design. I wonder why Apple doesn't release the 6502 P-code interp

Probably because they wouldn't be able to find it. Even if they did locate
it, there are probably third-party IP considerations and they're not going to
incur the legal costs and bother to review it.

I often look at the PDP-11 code for the P-code interp, it's a very clean design. I wonder why Apple doesn't release the 6502 P-code interp
I move the boot sector to a ProDOS BIN file by creating a temp bin file to hold block 0:
bsave /ram/boot,a$800,l$200
then I use ProSel's BlockWarden (Also on ProDOS 2.4.2) to F)ollow File "/ram/boot" to see what block was allocated to hold it's 512 data bytes.
Then I C)hange the slot & drive to the device with the boot block I want to copy and R)ead block 0 into Block Warden.
Then I C)hange back to S3,D2 and W)rite the block to the block # found earlier from F)ollow file.
Then I copy /ram/boot to a HD partition, then disassemble it.
Apple Pascal is based on UCSD II.1, of which there are no surviving sources known to the UCSD open-source team. II.0 is the most recent version to be open-sourced.
I have compiled the II.0 Filer source under my Pascal 1.4a and gotten it to run. I have not been able to compile+run the System due to the many changes Apple made to the II.1 runtime.
I made 1.4a as a heavily optimized successor to 1.3, which loads into aux LC to coexist with ProDOS. 1.4a launches from ProDOS, quits back to ProDOS, and requires 65c02 opcodes and 128K.
1.4a places pcode and constant data in aux 64k with user data in main 64k, similar to 1.2 & 1.3, but has a lot less bank-change overhead than 1.2 or 1..3. 1.4a can also mount a Pascal HD partition of up to 16MB on a ProDOS disk using Willi Kusche's modified Profile driver & utils.
My goal with 1.4 was to speed up the pcode interpreter and modify the BIOS to use ProDOS as the native file system, similar to how the Z-80 port of II..x used CP/M for device access and file I/O.
However, my 1.4 effort stalled when I moved into upgrading ProDOS & creating VidHD.
I like the Datamost PDQ tools which include a pcode assembler and disassembler, but it has problems with the 1.2/1.3 file format. Anyone know of a good disasm+asm combo for 1.3? Even better would be a decompiler, but that appears to be a manual process.

Maybe a viable alternative would be a cc65 program with...
d = dio_open(device);
dio_read(d, 0, buffer);
dio_close(d);
f = open("/ram/boot", O_WRONLY);
write(f, buffer, 512);
close(f);

In the 1980s I used a Disk Editor and Disassembler under the p-System.
Last year I extracted the first 1kB using a HexEditor and the Disk Image
(running Windows). My favourite Disassembler in the world of Windows is
DASMx 1.40.

I did this job again last year because there was no Apple II available.
The boot sectors of Apple Pascal 1.1 and 1.2 are the same. Version 1.3
(from 1885) is different I think because of SmartPort. Version IV.0
(from 1981) is also another code.
Do you use another mail address than Google? If yes send PM, and I send
you my files. These configuration files for DASMx are not perfect but
more than raw code :-)

In 1986 I got most of the sources of Apple Pascal 1.1 (BIOS&Interpreter,
Command, Filer and probably some more, but no Assembler). I compiled my
own 1.1-System, optimized my BIOS with CMOS opcodes and added some very
fast drivers. I'm planning to restore this stuff. But I didn't touch the
disks for decades :-(
Now I'm interested in getting the assembler to add support for CMOS
opcodes, 65802 and more opcodes (i.e. Mitsubishi M50xxx).
> My goal with 1.4 was to speed up the pcode interpreter
I learned a lot about low level code :-) First I added CMOS opcodes
which shortened and accelerated the code noticeable. Than I changed the
structure of the driver table.

Ralf

Hi Raif. I would love to get the 1.1 sources and/or any improvements you'd like to share.
Here is a link to my 1.4a build from last year:
https://drive.google.com/file/d/0B9I8jo6bktRAZ3FyN2UzSWt0MEc wNUpOQ3djTHk4Y09HcHJJ/view
Usage notes below. My disasm & optimized BIOS/interp sources are a bit scattered, but I can pull them together for you too if you are interested.

@JBrooksBSI
Attached is an alpha version of my UCSD PCode v1.4 runtime. It includes the PPM (Profile HD Partition Manager) drivers for hosting pascal disk images on a ProDOS HD.
Attached are two disk images (rename _zip to .zip & extract).
1) 800K PCodeBoot.2mg (Slot 5, Drive 1)
2) 32MB PCodeDev.2mg (Slot 7, Drive 1)
I've tested these disk images on 3x emulators
1) GSplus (KEGS)
2) GSport (KEGS)
3) Virtual ][
Booting the 32MB slot 7 image (PCodeDev) will load ProDOS 2.4.1 NSC which contains a built-in driver for the no-slot clock. I plan to have the v1.4 BIOS call ProDOS to get date & time, but haven't gotten to that yet.

While v1.4a1 does have the pcode BIOS & INTERP running from aux with ProDOS launch & quit, I am not yet disabling the ProDOS /RAM disk which gets stomped by Pascal, so after quitting back to ProDOS, any app which tries to use /RAM will crash/hang.
I'd like to get the PPM Extended Filer working if possible. I'm also missing the PPM backup utility.
I like the PDQ pcode asm/disasm tools, but they are not compatible with 1.2/1.3 pcode files.
I'm currently using Dave Tribby's DISASSM tool on PRDEV as it will handle 1..3 opcodes and disassembles both pcode & 6502 procedures. Now I just need a way to modify those procedures (like PDQ asm).
Here are my improvements to the pcode runtime:
CfgGetOpBorder = 0 ;Change GS border color during pcode opcode fetch
CfgBiosBorder = 0 ;Change GS border color during bios calls
CfgPascal2 = 0 ;Incomplete. Attempt to use compiled UCSD ii.0 sources
CfgIrqOn = 1 ;Enable IRQ for GS control panel access
CfgP8Boot = 1 ;BIOS+INTERP in aux LC to allow startup from ProDOS + MLI calls + exit to ProDOS
CfgP8SysCom = 1 ;Save & restore SysCom area which overlaps ProDOS $BFxx
CfgP8Quit = 1 ;Quit back to ProDOS when XIT $D6 opcode executes
CfgFixDelKey = 1 ;Allow 'delete' key to act like backspace
CfgFastBiosCall = 1 ;Self-mod to call BIOS handlers instead of indirect jump
CfgNewInit = 1 ;Optimize pcode initialization code
CfgNewGetBig = 1 ;Optimize pcode arg fetch
CfgGetOpAuxMem = 1 ;Optimize pcode interp by keeping aux 48K enabled for arg fetch after pcode opcode fetch
CfgFastAndOrNot = 1 ;Optimize pcodes Op84_LAND, Op8D_LOR, Op93_LNOT
CfgFastAbiAdiNgi = 1 ;Optimize pcodes Op80_ABI, Op82_ADI, Op91_NGI, Op95_SBI
CfgFastAbrNbr = 1 ;Optimize pcodes Op81_ABR, Op92_NGR
CfgFastJump = 1 ;Optimize pcodes OpA1_FJP, OpB9_UJP
CfgFastOpJump = 1 ;Optimize pcode dispatch via 65c02 jump (abs,x) instead of 6502 mod jmp (abs)
CfgFastTrvStat = 1 ;Optimize stack traverse via 65c02 opcodes
CfgSmallTrvStat = 1 ;Smaller code size via 65c02 opcodes in OpB2_LDA, OpB6_LOD, OpB8_STR
CfgFastChkGDirP = 1 ;Optimize file dir cache checks via GDIRP high-byte chk & 65c02 opcodes
CfgSmallXEQERR = 1 ;Smaller code size in error dispatch via 65c02 opcodes
CfgFastSLDC = 1 ;Optimize short constant opcodes $00-$7F via 65c02 opcodes & direct dispatch of next pcode
CfgFastLDC = 1 ;Optimize OpB3_LDC
CfgFastLdmStm = 1 ;Optimize OpBC_LDM, OpBD_STM
CfgFastXJP = 0 ;Buggy
CfgFastNew = 1 ;Multiple optimizations to Csp01_NEW
CfgFastMarkRls = 1 ;Multiple optimizations to Csp20_MRK, Csp21_RLS
CfgFastIntMulDiv = 0 ;Incomplete
CfgFastOnline = 1 ;Opt Csp05_UREAD, Csp06_UWRITE, Csp0C_USTAT, Csp23_UBUSY, Csp25_UWAIT, Csp26_UCLEAR, UnitOnline, ClearSysUnit
CfgFastGetBlockBuf = 1 ;Optimize alloc of 512-byte BlockBuf
CfgFastURWIS = 1 ;Optimize dispatch to user drivers
CfgRequireIIe = 1 ;Remove 80-col on 40-col ][+ features (L/R screen toggle, auto-follow, force-uppercase)
CfgFastReadWrite = 1 ;Initial optimizations for Csp05_UREAD, Csp06_UWRITE
CfgFastConText = 0 ;1 ;Buggy in PPM. Optimize CWRITE
CfgFastText80 = 0 ;Incomplete. Fast replacement for 80-col firmware
CfgFastPower10 = 1 ;Optimize Csp24_POT
CfgFastOp9F_LDCN = 1 ;Optimize Op9F_LDCN
CfgGetOpIncHi = 1 ;Smaller code size in GetOp PC page increment
There are two 800K pascal disk images you can mount with PPM that have the UCSD II.0 sources on them if you want to try compiling it:
II0SRCB UCSD II.0 B
II0SRCA UCSD II.0 A

I'm planning to restore the whole stuff. You must be patient :-)
I mentioned the fact that there were source files available in the 1980s
in West-Germany. Probably another p-System enthusiast may remember this.

Thanks.

I got the source files on 140kB disks. So the sources were partitioned.
I merged them because I used a 640kB drive, 1MB RAM disks and the UCSD
editor from the Modula-2-System which is not really limited in file
size.

(The first printout is on a thermal printer paper scroll from the first printer I had for my Apple II Plus, way back when.) If you can use it, John Brooks (who lives across the S.F. bay from me, I.I.R.C.) is welcome to come to my house and copy the disk for publication on Asimov. Or, you could send me a floppy and a return S.A.S.E. mailer and I'll make a copy of it for you. Email me personally to arrange things.

Have you ever though of using an atmel/microchip/AVR, convert 6502 assembly code to AVR, and use the AVR as a fast pcode engine

No. But there is a 20years old dream :-) Running the p-Machine native
on a Motorola 68060.

but the ultimate, is to use one of those opencore cpumaker and generate a FPGA P-engine and run at hardware level?
