CD≥≤ Prototypes

Beim Abbummeln meiner XOL 50 Freistunden-CD stieŖ ich vor lšngerer Zeit auf eine Seite mit Bildern und Beschreibungen von Prototypboards fŁr das CD≥≤ bzw. die CD≥≤ Erweiterung "CD1200" und die Erweiterung "CD Gamesystem 030"
Gemacht wurden die Bilder u.a. von Ryan E.A. Czerwinski der heute noch so aussieht wie die Computerpioniere von frŁher ;-) Und Besitzer(?) von Merlancia ist, die ja unter anderem die Rechte am Amiga MCC Design usw. gekauft haben. AuŖerdem scheint er auch eine Vielzahl der Boards, die Dave Haynie 2001 bei ebay versteigerte, gekauft zu haben. Vielen Dank Ryan!
Doch jetzt legt los mit Euren Englischkenntnissen.

CD≥≤ loop around prelim w/o anti-corrosive and low nr final. This is the loop around card that is used on the CD≥≤ with products such as the MPEG (FMV) card and the 030 card (as seen in this set also).

CD≥≤ debug (test) board Rev1 final. Used to test and add ports to the CD≥≤

Close-up of the silk-screen text on the CD≥≤ debug board Rev1

CD≥≤ debug (test) board Rev2 prelim, incomplete. Same as the rev 1 board, save for a few minor changes.

Audio switch board rev 2.0 (for CD≥≤?) prelim. No anti-corrosive. Part of WC Engineering Centre test system. "Real usage undetermined".

Zoom in of silk-screen on Audio switch board.

CD Error rate counter Rev 1.0, for CD≥≤. Part of WC Engineering Centre test station. Used to check errors on the cd controller.

YC Test Card Rev 1. Used on CD≥≤ test station at Commodore West Chester. IIRC, it is used to test the serial/keyboard port.

"Spellbound" Revision 4.1 preliminary logic board and CD controller. No anti-corrosive. "Spellbound" was the internal code name of the CD≥≤.

CD≥≤ CD Controller card prelim Rev 1.0 without anti-corrosive masking. This controls the Phillips CD-ROM on the CD≥≤.

Back side of "Spellbound" logic board.

CD1200 case- The CD1200 was the expansion module for the A1200 that gave it a CD-ROM drive and the ability to run CD≥≤ programs. The unit was never produced. It resembled a CD≥≤ case that was cut in half, and schematics for the device are also in the hands of ITACHA. The shown CD1200 is the only known case unit and has no logic board in it. Others most likely exist. Their status is currently unknown.

CD1200 case back plane. Note the cutouts in the back plane for ports.

"CD GAME SYSTEM 030" card. This is an accelerator for the CD≥≤. Sorry, it does not work (properly). Commodore planned ot produce a CD≥≤ mouse and keyboard set with a Workbench CD at one time. This would have been used in conjunction with the "computer kit". A CD≥≤ mouse is in possession of ITACHA
