The PVI(2636) provides the chip select signals according to signals provided by the CPU address lines. The PVI has 12 address line (A0-A11) which give him control over 4K. A11 of the PVI is not connected to A11 of the CPU, but connected to the cartridge slot. On the cartridge it is connected to A12 of the CPU which extends the addressable Range to 8K. This is also the maximum usable space, because A13 and A14 of the CPU are not used. With the above in mind address range will look like this: $0000 - $15FF ROM, RAM $1600 - $167F unused $1680 - $16FF used for I/O Control on main PCB $1700 - $17FF PVI internal Registers and RAM $1800 - $1DFF ROM, RAM $1E00 - $1E7F unused $1E80 - $1EFF mirror of $1680 - $167F $1F00 - $1FFF mirror of $1700 - $17FF $2000 - $3FFF mirror of $0000 - $1FFF $4000 - $5FFF mirror of $0000 - $1FFF $6000 - $7FFF mirror of $0000 - $1FFF On all cartridges for the Interton A11 from PVI is connected to A12 of the CPU. There are four different types of Cartridges with the following memory mapping. Type 1: 2K Rom or EPROM mapped from $0000 - $07FF Type 2: 4K Rom or EPROM mapped from $0000 - $0FFF Type 3: 4K Rom + 1K Ram Rom is mapped from $0000 - $0FFF Ram is mapped from $1000 - $13FF and mirrored from $1800 - $1BFF Type 4: 6K Rom + 1K Ram Rom is mapped from $0000 - $15FF (only 5,5K ROM visible to the CPU) Ram is mapped from $1800 - $1BFF One other type is known for Radofin (rom compatible to VC4000, but not the Cartridge connector). It consisted of a 2K ROM and 2K RAM which are most likely mapped as follows (needs to be confirmed): 2K Rom mapped from $0000 - $07FF 2K Ram mapped from $0800 - $0FFF The Cartridge is called Hobby Module and the Rom is probably the same as used in elektor TV Game Computer which is a kind of developer machine for the VC4000. Go to the bottom to see the game list and emulation status of each. ****************************************************************************** Elektor TV Games Computer This is much the same as the vc4000, however it has its own ROM (with inbuilt monitor program similar to the Signetics Instructor 50), and 2K of ram. No cart slot, no joystick, but has a cassette interface. ToDo: - Most quickloads don't work too well - Might need to rework keyboard, again When booted you get the familiar 00 00 pattern. Pressing Q gives a display of IIII. Now, you enter a command. Key Command Purpose ------------------------ Q Start Boot up system L RCAS Load a tape S WCAS Save a tape W BP1/2 Set a breakpoint R REG View/Set registers X PC Go +pad + Enter data and do next thing -pad - Decrement - MEM Specify an address 0-9 0-9 Hex digits A-F A-F Hex digits Keyboard layout when using the Monitor on real hardware (n/a = key not assigned) n/a RCAS WCAS C D E F Start BP1/2 REG 8 9 A B n/a PC MEM 4 5 6 7 Reset - + 0 1 2 3 This wouldn't fit too well on our keyboard with any chance of remembering it, so I've hooked it much the same as the Instructor. The Select key (Z) and the joystick don't actually exist, but I've left them in the keyboard matrix for now. Quickloads ---------- You can load pgm and tvc files with the quickload facility. The quickloads are meant for the ElektorTVGC, however with a bit a trickery they can be made to work on the vc4000 as well. Procedure: - Get a copy of the Elektor bios and rename it to ELEKTOR.BIN then save it with the rest of your vc4000 carts. - Start vc4000, and load ELEKTOR.BIN into the cartslot. Now your vc4000 thinks it is an Elektor. - Load a quickload file. Some of them will work, and in some cases, better than on the Elektor system. Pasting ------- This system uses the standard trainer paste codes: 0-F : as is + : ^ - : V MEM : - MON : Q Here's a sample from the manual, page 34/35 (down-arrow to escape)

Most carts contain a number of variants of each game (e.g. Difficulty, Player1 vs Player2 or Player1 vs Computer, etc). Press F2 (if needed) to select which game variant you would like to play. The variant number will increment on-screen. When you've made your choice, press F1 to start. The main keys are unlabelled, because an overlay is provided with each cart. See below for a guide. You need to read the instructions that come with each game. In some games, the joystick is used like 4 buttons, and other games like a paddle. The two modes are incompatible when using a keyboard. Therefore (in the emulation) a config dipswitch is used. The preferred setting is listed below. (AC = Auto-centre, NAC = no auto-centre, 90 = turn controller 90 degrees). The list is rather incomplete, information will be added as it becomes available. The game names and numbers were obtained from the Amigan Software site.
