I was thinking of performing Mr. Barry Orlando's 32768 color upgrade on my Mega ST2 (Motherboard Rev. .5.0) and the chip I found is not the Shifter chip he says I'd need. He lists part number: C025914-38A. I have what I think is a Shifter chip, but he part number on the chip, which I pulled from a newish 1040ST (it came with Mega TOS) is: C07013-002 (C)ATARI 1987 -31 I10356-01 8821KRR Am I totally hosed? Also, he says (in the text file posted a while ago) if my RAM chips were slower than 120 nanoseconds, then I'd have to do something else. The chips in my computer are: M411024HP -15C*(M) AT&T 11187 74 Does anyone know what speed they are? One more thing, Mr. Orlando says: "Three wires are installed from the color board to three vias (trace thru holes) located nearby on the motherboard." What is he talking about? I didn't see anything like that at all in the 1040ST. Is there anything equivalent I should be aware of in doing this on my Mega 2? Will I have to do anything truly different in this upgrade compared to doing it to a 1040ST? Please let me know. --Cliff -- cliff@jarthur.claremont.edu | "Ted Striker? Never heard of him.
