Explanation of how it work the program “RAM3_RAMFAIL_BAS” written by Dominic Brown in the 1990 in Super Basic for the Sinclair QL which is used to calculate what the RAM on the Sinclair QL is broken, you need to use the MINERVA ROM (RAM PassCheck).
I tried to explain how it work and i have rewrote the software in a “language” a bit more modern ;-D
MINERVA OUTPUT EXAMPLE:
——————————————
WRITE: 5 4 8 C 4 8 7 8
READ: 5 C C D 5 C C D
ADDRESS: 0 0 0 3 2 0 0 0
——————————————
HEX WRITE: 54 8C 48 78
HEX READ: 5C CD 5C CD
Convert the numbers in decimal:
DECIMAL WRITE: 84 140 72 120
DECIMAL READ: 92 205 92 205
You have to make a xor in pairs (write & read)
XOR: 84 XOR 92 = 8
XOR: 140 XOR 205 = 65
XOR: 72 XOR 92 = 20
XOR: 120 XOR 205 = 181
Now you need to do an OR with the result of the XOR starting with “0″ and continuing with the result of every OR
OR: 0 OR 8 = 8
OR: 8 OR 65 = 73
OR: 73 OR 20 = 93
OR: 93 OR 181 = 253
Convert the final result of the OR in Binary.
DECIMAL: 253
HEX: FD
BINARY: 11111101
Follow the table to find the faulty ram. Pay attention to the memory address.
1: BAD Ram
0: GOOD Ram
BINARY = 1 1 1 1 1 1 0 1
IF < $30000 (ADDRESS) = IC8 ,IC7 ,IC6 ,IC5 ,IC4 ,IC3 ,IC2 ,IC1
IF > $30000 (ADDRESS) = IC16 ,IC15 ,IC14 ,IC13 ,IC12 ,IC11 ,IC10 ,IC9
IF > $40000 Faulty ram is in expansion memory.
The Original Program (ram3_ramfail.bas) was written for the SINCLAIR QL in SUPER BASIC language by Dominic Brown (1990).
Documentation of how it work by Xad/Nightfall (2015).
Thanks to my friend for the support.
Faulty Ram Decoder Changelog:
- v0.1: First Release.
- v0.2: Added a message (Faulty ram is in expansion memory) if the Address > $40000.

CBM prg Studio Version 3.2.2 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.
Improvements:
- Import binary file as disassembly.
- Set sprite scratch pad background colour.
- Keyboard short cuts for collapsing/expanding regions.
Bug Fixed:
- Basic:
- Improved syntax highlighting.
- Wrong case used when commenting certain lines.
- Commenting blank lines.
- General:
- Menu and/or tool bar was hidden occasionally.
- Saving to network drives.
- Source overview settings not retained.
- Display problems with medium and large fonts.
- Better file handling with network drives.

Relaunch64 is an IDE (text-editor) for C64 assembler-coding on Windows, Linux and Mac OS X. Relaunch64 has a clean and intuitive user interface, yet it offers many features that make coding faster and easier.
Java 7 or higher is required to run Relaunch64. The program is licensed under the GNU GPL 3 (or higher) and free for private and professional use.
This editor works together with common cross assemblers like Kick Assembler, ACME, or 64tass. Other assemblers might work as well, but syntax highlighting may not be 100% correct.

YMT-Player is a player that allow you to play Project-Ymer YMT files (Windows) on the Atari ST. The program is made by Peter Jørgensen aka. fedepede.
What is Project-Ymer YMT files ?
YMT files are like the YM/AY files. Music files where you sampled data from the sound chip register (YM2149/AY8910) in a certain interval, instead of having a dedicate player. Up to now (to my knowledge), there have only been YM/AY player that could play tune/score files, that was sampled at 50HZ, but the YMT player can play files up to 300hz (there are some 50hz+ tunes/scores include in the examples)
The advantaged of AY/YM/YMT format, is that to replay these tunes/scores cost very little CPU power, so if you need a lot power for a eg. a 3D demo, when it could be a wise choice to use it, because it leaves most of the CPU power for 3D calculations and the graphic etc, and the disadvantaged is that it use a lot of memory, and also that it is nearly impossible to make a routine that can capture and use the SID sound and Samples etc. It is also why those files need to be hand made, that is the reason why YMT-Player only support pure YM2149 sound.
The zip archive contains the Floppy/HD version and Sources.
Changelog:
Ymt-Play Ver 1.01 Release Date 16.Jan.2015
- Reactivate the clear screen function when the program start.. I deactivate it , so I could tested the program, but I forgot to turned on it again.
