Hi,

you may found-it here: https://github.com/Laci1953/RC2014-CPM/tree/main/ADVENTURE

It runs on any Z80 machine under CP/M.

Ok thats good,

How do I compile it ?

Derek

Hi Derek,

use:

c -v -c -o advent.c
c -v -c -o database.c
c -v -c -o english.c
c -v -c -o itverb.c
c -v -c -o turn.c
c -v -c -o verb.c
z80as rand

then:

xsub
link
-ptext=0,data,bss -c100h -oadvent.com \
crtcpm.obj advent.obj database.obj english.obj itverb.obj \
turn.obj verb.obj rand.obj libc.lib

Or, use the shortcut:

c -v -o advent.c database.c english.c itverb.c turn.c verb.c rand.as

However, if you use the original HiTech C compiler, you will encounter some problems while compiling (assembling)...

First issue: the // comments. This can be fixed immediately by using the old-style /* ... */ comments ...

Second issue: I tried to compile using the original HiTech C (using the modified sources with /* ... */ comments).

Here is what happens:

I>c -v -c -o advent.c
HI-TECH C COMPILER (CP/M-80) V3.09

Of course, I used my enhanced HiTech C compiler & Z80AS, to avoid all problems... so, I advice you to do the same.

Next daft question, Where is your version on the C compiler. I found https://github.com/Laci1953/HiTech-C-compiler-enhanced/tree/main
This has directories for the mentioned programs C, CCP etc, No executable in them, do i LOAD the hex files to obtain the COM file?

I found the new CP/M Putsys files, but at some point I see mention of the SCM Rom searching for the Bank switching code from address 7f00 onwards. Do I need a modified ROM?

I can't seen to see a set of "howto" create the New C compiler anywhere, I see the "This is what it does and the principles of how" - just no actual this is what you need to do instructions.

I have used several versions of the Adventure program. Beginning back
around 1978 on a DEC System 10. It always amazed me the things they
thought of. (For example, try siccing the bird on the dragon.)

Then later a C version but I did finally buy a copy of the CP/M version
to run using an 8080 simulator (com from DDJ) on CP/M-68K. I poked
around on the old hard drive and found these files along with a version
of the manual that I created from scans.

Hi Derek,

here are the details:

1. The enhanced HiTech C
------------------------------------------

To implement on your computer the enhanced HiTech C, you need to copy the appropriate .HEX files (according to your hardware), here I will use the "generic" names, then execute:

LOAD CPP
LOAD P1
LOAD CGEN
LOAD OPTIM
LOAD Z80AS
PIP ZAS.COM=Z80AS.COM

2. The smaller CP/M (for 128KB RAM Z80 computers)
--------------------------------

To change your CP/M with the smaller CP/M, to be able to run the enhanced HiTech C for 128KB RAM Z80 computers, select in https://github.com/Laci1953/RC2014-CPM/tree/main/PutSys the appropriate .hex file (according to your RC2014's serial type & CF size), and, under SCM:

load the *_PutSys*.hex
then
*g8000<CR>

Your CP/M is ready and can be booted:
*cpm<CR>

3. The boot ROM
---------------------------
This is a mandatory step only for computers provided with the 512KB ROM + 512KB RAM board.
(For computers provided with Steve Cousins SCM, e.g. SC108, this step is not mandatory, you can boot CP/M from SCM)

Choose the appropriate .hex file (according to your RC2014's serial type & CF size), and burn-it to an (E)EPROM, insert the EPROM to your board.
Now, at power ON, the CP/M directly boots.

All these details are also to be found on GitHub, by the way.
I consider these steps very simple.
I hope you can now try-it.

regards,
Ladislau

Hi Derek,

the boot files are here: https://github.com/Laci1953/RC2014-CPM/tree/main/BOOT

Please let me know if you still have problems with the smaller CP/M, booting-it, or with the enhanced HiTech C compiler...

Ladislau

Hi Derek,

I just realized that you need a Z80 computer provided with SCM in order to store the smaller CP/M to the appropriate CF ...

The procedure is the following: (let's say you have a SC108, running SCM, and you want to store the smaller CP/M on a 512KB RAM Z80 computer provided with ACIA and 64MB CF)

On the SC108 computer, insert in the CF board the CF to be used on the 512KB RAM machine, boot, paste on the terminal the ACIA_PutSys_CF64_CPM_DA00H.hex file, then:

*g8000<CR>

Now, the CF contains a CP/M to be used on your 512KB RAM computer, you will need to move the CF on that machine.

Seems a little complicated, but it's the only way I know so far...

regards,
Ladislau

Hi all,

I added to https://github.com/Laci1953/HiTech-C-compiler-enhanced ,

the file "How to install" ,

containing the following text:

---------------------------

Here are the necessary 3 steps, depending on your specific Z80 computer's hardware:

1. The boot (E)EPROM

This is a mandatory step only for computers provided with the 512KB ROM + 512KB RAM board.
(For computers provided with Steve Cousins SCM, e.g. SC108, this step is not mandatory, you can boot CP/M from SCM, so go to step 2)

For computers provided with 512KB RAM, you need to boot CP/M at power ON, in order to use the enhanced HiTech C compiler.
Running CP/M from ROMWBW will not allow the enhanced HiTech C compiler to be executed !

Choose the appropriate .hex file (according to your RC2014's serial type & CF size), and burn-it to an (E)EPROM, then insert the EPROM to your 512KB RAM + 512KB ROM board.
Example: you have a Z80 computer with an ACIA serial and 64MB CF. You will choose the CPM_boot_512_ACIA_CF64.hex file.
Now, at power ON, the CP/M directly boots.

2. The smaller CP/M (for 128KB RAM Z80 computers)

This step is mandatory only for 128KB RAM computers.
(For computers provided with 512KB RAM + 512KB ROM boards, you may use the "original" CP/M, go to step 3)

To change your CP/M with the smaller CP/M, to be able to run the enhanced HiTech C for 128KB RAM Z80 computers, you need to
paste on the terminal the appropriate .hex file.
Example: you have an 128KB RAM Z80 computer with an ACIA serial and 64MB CF. You will choose the ACIA_PutSys_CF64_CPM_DA00H.hex file.

Then:
*g8000<CR>

Now, the CF contains a smaller CP/M.

3. The enhanced HiTech C

This step is mandatory for all computers.

To implement on your computer the enhanced HiTech C, you need to copy the appropriate .HEX files (according to your hardware), here I will use the "generic" names, then execute:

LOAD CPP
LOAD P1
LOAD CGEN
LOAD OPTIM
LOAD Z80AS
PIP ZAS.COM=Z80AS.COM

Now, you have the enhanced HiTech C installed.
----------------------------

Many thanks Derek for pointing out the need to have a clear "install instruction" text for the enhanced HiTech C compiler !!!

Ladislau

Hi,
I have installed the correct version of CP/M on an SC114. It boots into cpm 2.2 ok.

I downloaded the 128k versions of cpp p1 cgen optim z80as (cgen only had one version, no 512/128 option).
I ran the LOAD util with each file to get the new versions of the files.

I downloaded the adventure game and tried:

G>c -v -c -o advent.c
HI-TECH C COMPILER (CP/M-80) V3.09
Copyright (C) 1984-87 HI-TECH SOFTWARE
0:CPP -DCPM -DHI_TECH_C -Dz80 -I ADVENT.C $CTMP1.$$$
0:P1 $CTMP1.$$$ $CTMP2.$$$ $CTMP3.$$$

But it never gets past p1 ?

This is my directory (with the adventure files and updated hitech files) Do they look about the same size as your files?

Hi Derek,

let's check, step by step...

First, your CP/M. (I suppose that's the problem...)

Try this:

Oh, I did not know you have ACIA...

The CP/M seems OK !

Let's dig deeper...

Try this:

*

The 7'th JP from 69H is in my case JP $04FD.
At 04FD, the code MUST contain:

LD HL,xxxx
LD B,A
LD A,C
CP $2C ;HERE, STEVE CHECKS FOR THE MAX FUNCTION # - in my case $2C

(this means, my SCM version contains the functions $2A and $2B, to move bytes from/to the high 64KB RAM bank.)

Check, on your computer, the code at $7B (the 7'th JP). It's a JP to some address. Check that address (d addr).
I suppose you will find , on your computer:

LD HL,xxxx
LD B,A
LD A,C
CP $2A ;HERE, STEVE CHECKS FOR THE MAX FUNCTION # - in your case $2A

I suppose you have an older version of SCM (without the functions $2A and $2B).

In this case, we must use another solution...

but first, I wait for your response...

My version is:

Small Computer Monitor by Stephen C Cousins (www.scc.me.uk)

I think this looks ok
my CP instruction checks for $2c :

ok, lets check the code of functions $2A and $2B ...

on my computer:

Is this code also on your computer?

Ladislau

Hi Derek,
please download again the optim128.hex... I updated it 10 minutes ago

the sizes should be:

CGEN COM 48k 369
CPP COM 28k 223
P1 COM 44k 340
OPTIM COM 36k 258

My version has an extra jump:
so from the top:
0519: 21 2B 05 !+. LD HL,$052B
52b+2a+2a = 57f

*m57f
057F: E0 1C E3 1C C9 21 A1 05 79 FE 03 30 09 06 00 09 .....!..y..0....
058F: 09 46 23 66 68 E9 AF 47 67 6F C9 C3 48 03 7B C3 .F#fh..Ggo..H.{.

*d1ce0 THIS SHOWS an extra JP to the code
1CE0: C3 91 1F ... JP $1F91
1CE3: C3 9C 1F ... JP $1F9C

1F91: 0E 30 .0 LD C,$30
1F93: 06 01 .. LD B,$01
1F95: ED 41 .A OUT (C),B
1F97: 1A . LD A,(DE)
1F98: 05 . DEC B
1F99: ED 41 .A OUT (C),B
1F9B: C9 . RET

It looks like it does something similar

Derek

Hi Derek,

the mystery is solved!!!

turns out that your SC114 has other ports used to select the ROM/RAM banks, compared to SC108:

SC108:

MEMP_PORT equ 38H

; ROM 0000 to 8000H
; ROM_OUT_CMD equ 00000001B
ROM_IN_CMD equ 00000000B
LOWER_64RAM equ 00000000B
UPPER_64RAM equ 10000000B

1D8C: 0E 38 .8 LD C,$38
1D8E: 06 80 .. LD B,$80
1D90: ED 41 .A OUT (C),B
1D92: 1A . LD A,(DE)
1D93: 06 00 .. LD B,$00
1D95: ED 41 .A OUT (C),B
1D97: C9 . RET

SC114:

1F91: 0E 30 .0 LD C,$30
1F93: 06 01 .. LD B,$01
1F95: ED 41 .A OUT (C),B
1F97: 1A . LD A,(DE)
1F98: 05 . DEC B
1F99: ED 41 .A OUT (C),B
1F9B: C9 . RET

Can you please list also the $1F9C routine?

I will modify the source files, with a new option : SC114 !!! I was convinced that is similar to SC108... but IT'S NOT !!!

I checked the sizes after downloading and LOADing again.
369 48k 2 R/W G:CGEN.COM
223 28k 1 R/W G:CPP.COM
258 36k 2 R/W G:OPTIM.COM
340 44k 2 R/W G:P1.COM

They look ok to me. It was the P1.COM file that failed not optim.com

if i run just optim.com it responds with nothing or if i give it a filename (not a real one) it responds not found.
if i run p1.com the system locks until reset

Hi Derek,

I must rebuild P1, CGEN & OPTIM, for SC114.

Can you please list also the $1F9C routine?

Ladislau

Thanks Derek,

now, back to the source code...

I will notify you after finishing the modifications needed for SC114... it will take some time :(

ok thanks,

When your ready I will test it foe you - no problem. And no rush.

Derek

Hi Derek,

I published the versions for SC114 on GitHub.

You need to copy only P1_114.HEX , CGEN114.HEX , OPTIM114.HEX , then LOAD them.

I tested the executables on a configuration using the Phillip Stevens 32KB ROM + 128KB RAM memory module, which is compatible with SC114, they work OK.

When compiling the game, you will get some warnings, it's OK...

regards,
Ladislau
