The conditions of this Commodore 8032-SK (Gold Label) are really bad. The CBM 8032-SK is left for over 25 years in a dovecote.

The cleaning, repairing and restoration have taken a very long time, but the result is more than acceptable.

The comparison (before / after):

Defects:

  • The Commodore 8032-SK was completely dead (Black screen of death).
  • Little problems of CRT geometry.

Repair:

  • Replaced the CPU 6502.
  • Yoke calibration of the CRT

Coleco Vision Secam (91162-D) with Y (B-Y) (R-Y) to RGB encoder

December 31st, 2013 1 comment
CBS Coleco Vision Secam

Autopsy:

This version of Coleco Vision SECAM (Péritel/Euroconnector) uses a PCB 91162 REV D which differs from the classical version with PCB 91209 because integrates an internal video encoder from Y (BY) (RY) to RGB which is separate from the motherboard.

This makes think that in theory all PAL versions that use the VDP 9929A with PCB 91162 REV D and RF output can be modified to have a RGB output signal by adding this external video encoder.

from Wikipedia homepage:

The ColecoVision is Coleco Industries’ second generation home video game console, which was released in August 1982. The ColecoVision offered near-arcade-quality graphics and gaming style along with the means to expand the system’s basic hardware. Released with a catalog of 12 launch titles, with an additional 10 games announced for 1982, approximately 145 titles in total were published as ROM cartridges for the system between 1982 and 1984. River West Brands currently owns the ColecoVision brand name.

In 2009, IGN named the ColecoVision their 12th best video game console out of their list of 25, citing “its incredible accuracy in bringing current-generation arcade hits home.”

Coleco licensed Nintendo’s Donkey Kong as the official pack-in cartridge for all ColecoVision consoles, helping to boost the console’s popularity. By Christmas of 1982, Coleco had sold more than 500,000 units, in part on the strength of its bundled game. The ColecoVision’s main competitor was the arguably more advanced but less commercially successful Atari 5200.

The ColecoVision was distributed by CBS Electronics outside of North America, and was branded the CBS ColecoVision.

Sales quickly passed 1 million in early 1983, before the video game crash of 1983. By the beginning of 1984, quarterly sales of the ColecoVision had dramatically decreased.

Over the next 18 months, the Coleco company ramped down its video game division, ultimately withdrawing from the video game market by the end of the summer of 1985. The ColecoVision was officially discontinued by October 1985. Total sales of the ColecoVision are uncertain but were ultimately in excess of 2 million units, as sales had reached that number by the spring of 1984, while the console continued to sell modestly up until its discontinuation the following year.

In 1986, Bit Corporation produced a ColecoVision clone called the Dina, which was sold in the United States by Telegames as the Telegames Personal Arcade.

CBM prg Studio v2.9.0 released

December 21st, 2013 No comments

CBM prg Studio Version 2.9.0 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.

New features:

  • Extended colour mode for screen designer.
  • Binary file import for screen designer.
  • User defined links in Help.
  • Batch files for user tools menu.
  • Updated help file.

Bug Fixed:

  • Assembler
    • WORD sequences ending in , not reported.
    • ROL, LSR, ADC, SBC not setting status flags in debugger properly.
    • STX/STY reporting invalid address mode.
    • Macros after cheap labels weren’t expanded properly.
    • Macros containing tabs or comments weren’t expanded properly.
    • Labels after ‘Incasm’ were not recognised.
    • Indirect jumps not recognising labels
    • Wrong detection of assembling past end of memory.
    • Comments after macro calls were corrupting the parameters.
    • Build events were not exported properly.
  • Screen Designer
    • ‘Undo’ undid everything, not just the last operation.
    • Screen editor background colours can be set per character.
  • General
    • Some code reformatting issues
