Indeed no -- schematic is available for Sky skipper. Difference between Popeye and Sky -- skipper comes from MAME source code. -- -- Please read my Popeye.vhd hardware description which is almost the same as Sky -- skipper. Below main differences are highlighted when needed. -- -- Video quartz is 20.16MHz. -- -- Display is 512x448 pixels (video 640 pixels x 256 interlaced lines @ 10.08MHz). -- -- Original interlaced timings : -- 640/10.08e6 = 63.49us per line (15.750kHz). -- 63.49*256 = 16.254ms per frame (61.52Hz). -- -- VHDL 60Hz Adapted interlaced timings (263 lines instead of 256): -- 640/10.08e6 = 63.49us per line (15.750kHz). -- 63.49*263 = 16.70ms per frame (59.89Hz). -- -- VHDL 60Hz Adapted progressive timings (526 lines instead of 512): -- 640/20.16e6 = 31.75us per line (31.50kHz). -- 31.75*526 = 16.70ms per frame (59.89Hz). -- -- Char tile map and color are the same as Popeye. -- -- Sprites are the same as Popeye except for color palette: -- Only 1 global color bit is used and drives 2 address bits of color -- palette. last bit of color palette is stucked to '0'. -- -- Program rom is 4x8Kx8bits addressed as 32Kx8bits (only 28K used): -- addresses are bits swapped and xored w.r.t cpu addresses. -- data are bits swapped w.r.t cpu data. -- Swap order and xor differs from Popeye ones. -- -- Working ram is split in two non consecutives parts: -- 2Kx8bits (low part) + 1Kx8bits (high part) -- High part is addressed by cpu and by sprite data dma. -- -- The most important difference is in the background management. Popeye -- doesn't use H scroll and only little V scroll. In the opposite Sky skipper -- make a large use of H/V scrolling. -- -- It's not know if Sky skipper uses or not low/high nibble mecanism. Anyway -- the total amount of bitmap ram is the same as Popeye one and is accessed -- by CPU as 2 bank of 4Kx4bits. The bank selection is made by using bit 7 -- of the data to be written. Data bits 0 to 3 only are written to ram and -- are used as the individual bitmap bloc color. -- -- Sky skipper background bitmap is 128(H)x64(V) blocs of 4x4 dots (bg dot is -- 2 pixels x 2 lines). -- -- | #Y bloc position | #X bloc position | -- | 63 to 0 | 127 to 0 | -- bg ram address by cpu: | A(11-6) | D(7)-A(5-0) | -- bg ram address by video: | V: 64*4*2 lines | H: 128*4*2 pixels | -- -- -- One bloc has a single color and is 8 pixels x 8 lines. -- Total playground is 1024 pixels x 512 lines. -- -- Sky skipper required one additionnal bit to allow H scroll to go from 0 to -- 511 (0-1022 pixels since H scroll has a 2 pixels resolution). In original -- hardware this bit comes from sprite data buffer. In VHDL code it is latched -- directly from cpu write to working ram (@8C02) -- ---------------------------------------------------------------------------------
