VIPER
Volume 1 Files


Cover for Issue 2 (August, 1978)

Issue 2's highlight is a full analysis of CHIP-8 for the RCA COSMAC VIP. It's complete with flow charts, register maps, and a line by line commentary on each instruction/byte in the 512 byte image as published by RCA in the RCA COSMAC VIP Instruction Manual Part Number: VP-300-1 (1977). Note that the original has serious problems with print quality (admitted by the publisher) in the coding sheets that often have the address and/or data bytes unreadable. Since the VIP manual's CHIP-8 hex dump is available elsewhere, I am not attempting to correct the missing data since I'm simply doing a scan and not attempting to "re-typeset" the document at this time. The main goal is to gain access to J. W. Wentworth's very detailed analysis on the internal workings of CHIP-8.

Also of interest is that by Issue 10 of Volume 1 the contact information had changed to the following:

That being said, Aresco is probably gone, and I personally have no knowledge of the present copyright owner's whereabouts.
