Commodore 8296 (TAN Case)

The conditions of this Commodore 8296 (TAN Case) are really bad. The CBM 8296 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 8296 was completely dead (Black screen of death).
  • Little problems of CRT geometry.

Replaced parts:

  • Replaced PLA U6 with a OTP EPROM 27C512R 70ns + Adapter
  • Replaced the ROM 2 x 2764 Eprom with 1 x 27C128 Eprom (spare parts from a original cbm pcb)

Note:

I have replaced the original ROM (2 x EPROM) pcb because the PLA adapter is fat. I could insert a small castle (photo) between the ROM pcb and the Main Motherboard but in this time i have prefered to replace with a single Eprom.

SNDH Atari ST YM2149 Archive v4.3 released.

January 25th, 2014 No comments

SNDH archive v4.3 released - 4107 SNDH files (total 7719 tunes)

Ever since the birth of the Atari ST, different chip music formats have had different ways to use them. If you are coding a chip music player for the Atari ST you would have to use dozens and dozens of special ways to replay music.

But in the mid 90′s, BDC of Aura crew became tired of this inelegant system and decided to fix the issue once and for all. He then created the ‘SNDH’ file format. SNDH is actually the original songfile and replaycode with a header bolted on top of the music and replayer. The header has a unified calling interface no matter what type of chip music is hidden beneath it, and it has extended datas about the music.

Golden Image JD-560 / JD-562 (Boxed)

Autopsy:

The JD-560 and JD -562 are a series of Floppy disk drives that can be connected externally of the computer.

They are completely applicable to IBM PC/XT/AT/386/486 compatible computers and need no any special interface cards.

I couldn’t not take 2 x C64 at a good price for spare parts.

I couldn't not take two C64 at a good price for spare parts.

Payed €12,50 a piece, that is the right price.

Practically, the price of a good pizza and a glass of water ;-D

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.
