CBM prg Studio v3.13.0 released

June 29th, 2018 1 comment

CBM prg Studio Version 3.12.0 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.

CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.

CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.

It was also a good opportunity for a face lift and to add some new features, such as:

  • Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
  • Tabbed MDI.
  • Syntax highlighting.

What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.

This is mostly a bug-fix version, though there are some small new features.

Bugs Fixed:

  • Assembler:
    • Problems with spaces in expressions.
    • Problems with spaces in ‘repeat’ parameters.
    • Screen codes in byte/text directives not generated properly.
    • Breakpoints were not sent to a debugger properly when building projects.
    • Some zero page optimisation issues.
  • BASIC:
    • Renumber problems for programs with multiple ‘ON’ statements
    • Problems with importing/generating PI and other characters.
    • Some characters missing from import.
  • Screen Code tool:
    • CBM key would lock sometimes.
  • General:
    • Code snippets had to be re-generated.
    • ‘Go to’ dialog crash with large files.
    • ‘Go to’ dialog caused weird zooming issues.
    • Issues with selected columns of text.
    • Problems with compress/uncompress with some control codes.

See the help for a complete list of new features and fixed bugs.

Note In this version, each target machine can have its own default project directory. If you are upgrading from a previous version (before version 2.5.1) of CBM prg Studio you may be asked to set up your project directories again. Your current projects will not be affected.

Commodore MMF 9000 (SuperPET 9000) Repair & Testing

January 30th, 2018 1 comment
Commodore MMF 9000 (SuperPET 9000)

The SuperPET is a Commodore PET 8032 with one or two added boards that were designed at the University of Waterloo.

The computer has a built-in RS-232C interface and many programming languages on Floppy Disk. In Europe, this machine was called the MicroMainFrame 9000, or MMF 9000.

Let’s start to assembling the BMB Compuscience Ltd Board and Compu-Think 64K Memory Expansion board in the Commodore MMF 9000 (SuperPET)

I had to shorten the original standoffs installed in the computer because the length was wrong for the two boards BMB Compuscience/Compu-Think 64K. The long standoffs are used for the superPET Combo Board (the last one released).

It was not a simple job, obviously i have looked around for the identical standoffs with thickness, size, pitch and some with a long screw other with a short screw.

Between one phase and another i have also giving a nice clean inside and outside of the computer and of the motherboard.

Unfortunately there are a couple of problems after assembling the two boards of the MMF 9000 (SuperPET).

Defects:

  • The keyboard space bar dead.
  • Don’t runs any Waterloo program in the 6809 environment, runs only the Bootstrap menu which allows to load the programs from Floppy Disk, the Machine Language monitor and the Setup program both are in the Eprom.
  • The protection Dongle (6702) not correctly viewed from the system.

Repair/Fix:

  • The keyboard after a good cleaning has started to work well.
  • The Dongle after cleaning the contacts now works.

About the programs that don’t runs in the 6809 environment the repair was a bit longer. I have used the only program that worked under the 6809 environment, the Machine Language Monitor.

With this program i have filled the memory with the command Fill (f 9000-9fff aa) and i have changed from time to time the bytes that i was going to write in memory and  i have used the command (d 9000-) to see the results and not all memory locations are written correctly.

With the Bank Switching command (b 0, b 1 …) i have switch the memory bank, there are 16 banks of 4k each for a total of 64k.

I have found 7 x 4116 RAM failed (this card is new, never used), replaced these bad RAMs everything has started to work properly.

So my advice is to try to load the Waterloo software in the 6809 environment to make sure that the 64k memory expansion (only seen in the 6809 environment) is working properly.

Below the photos of all the tests that i have done:

  • Test with the CPU 6502 (Standard Commodore 8032/32k) with disk access, some software running in emulation 40 columns with the program: 80240.prg
  • Test with the CPU 6809 of the entire Waterloo software package with disk access.

The “Colour PET” Project

April 21st, 2013 No comments

Steve Gray started a new project. He uses an 80 column (monochrome) CBM/PET to display a 40 column screen with colour.

A normal 80 column CBM/PET uses two RAM banks for the text. Steve now uses one RAM bank for the text (40 columns) and the other RAM bank for the colour information.

ComputerTechnik SK-747 / IBS Space 84 (Apple II Clone)

ComputerTechnik SK-747 (Apple II Clone)

Autopsy:

This is a Apple II clone made by Computertechnik (SK-747 IBS Space 84) around late 70′s. This Apple computer resembles in all respects the original one.

from Wikipedia:

The Apple II is an 8-bit home computer, one of the first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak, manufactured by Apple Computer (now Apple Inc.) and introduced in 1977. It is the first model in a series of computers which were produced until Apple IIe production ceased in November 1993.

The first Apple II computers went on sale on June 5, 1977 with a MOS Technology 6502 microprocessor running at 1 MHz, 4 kB of RAM, an audio cassette interface for loading programs and storing data, and the Integer BASIC programming language built into the ROMs. The video controller displayed 24 lines by 40 columns of monochrome, upper-case-only (the original character set matches ASCII characters 0×20 to 0x5F) text on the screen, with NTSC composite video output suitable for display on a TV monitor, or on a regular TV set by way of a separate RF modulator.

The original retail price of the computer was 1298 USD (with 4 kB of RAM) and 2638 USD (with the maximum 48 kB of RAM). To reflect the computer’s color graphics capability, the Apple logo on the casing was represented using rainbow stripes, which remained a part of Apple’s corporate logo until early 1998. The earliest Apple II’s were assembled in Silicon Valley, and later in Texas; printed circuit boards were manufactured in Ireland and Singapore.

CBM-Command v1.0

May 27th, 2010 No comments

CBM-Command is a disk manager for the Commodore 64 and Commodore 128 computers.

It is written like Norton Commander or Midnight Commander, but is much simpler due to the target platforms.

Both the C128 and C64 have their own native version of the application.

Release Notes – 2010-05-26 – Version 1.0

New Features:

  • Simple text file viewer. Now when you use SHIFT-RETURN to open a file, it will ask if you want to view it as text. If you say yes it will present the file in the simple text viewer. If you say no it will launch as normal. If you have selected a SEQ file then it will open straight into the viewer upon hitting SHIFT-RETURN.
  • Help File.

Changes:

  • Fixed bug where you could move to an unopened panel.
  • Fixed bug where you could not abort a rename by leaving the name blank and hitting return.
  • Reworked how the panels are displayed to allow more characters of names to be displayed in 40 columns.
