Aleste Translation PROMs and EPROMs

Revision as of 19:37, 7 February 2010 by Nocash (Talk | contribs) (→‎Aleste VDKEY eprom (video and keyboard))

Aside from the BIOS EPROM, the Aleste 520EX contains five Translation PROMs and EPROMs. They aren't accessible as memory to the CPU, but rather used as "logic look-up tables", translating incoming signals (through address inputs) to to outgoing signals (through data outputs).

Aleste COLDAT eprom (Gate Array Parameters and Upper ROM Bank)

Inputs:
 A0..A7    Databus D0..D7
 A8        CPU A13
 A9        CPU A15
 A10       MAPMOD     ;affects ONLY the palette bits in COLDAT
Outputs: (enabled only when /IORQ=Low)
 D0..D5    XD0..XD5
 D6        Not used (not connected)
 D7        VRAMACC

Part A (when MAPMOD=0)

 0100..013F:  7FFFh     Gate Array 0 (palette index)
 0140..017F:  7FFFh     Gate Array 1 (palette data)
 0180..01BF:  7FFFh     Gate Array 2 (vmode, rom, leds)
 01C0..01FF:  7FFFh     Gate Array 3 (rambank, etc.)
 0200..02FF:  DFFFh     Upper ROM Bank
 0300..03FF:  FFFFh     ?  (filled with incrementing values: 00h..FFh)
Part B (when MAPMOD=1)
 0400..04FF:  5FFFh     ?  (filled with incrementing values: 00h..FFh)
 0500..053F:  7FFFh     Gate Array 0 (palette index)    (same as MAPMODE=0)
 0540..057F:  7FFFh     Gate Array 1 (palette data)     (other than MAPMODE=0)
 0580..05BF:  7FFFh     Gate Array 2 (vmode, rom, leds) (same as MAPMODE=0)
 05C0..05FF:  7FFFh     Gate Array 3 (rambank, etc.)    (same as MAPMODE=0)

Aleste MAPPER prom (Gate Array 3, RAM banking)

This 256x4bit PROM assists Gate Array 3 (RAM banking) 

Inputs:
 A0..A1     CPU A14..A15  ;-the addressed 16K memory block
 A2..A5,A7  M0..M4
 A6         MAPMOD
Outputs:
 D0..D3     MAP14..MAP17

Addresses used when MAPMOD=0: 

0000: 0 1 2 3  0 1 2 7  4 5 6 7  0 3 2 7 ;-1st+2nd 64K banks (as on cpc 6128)

00B0: 0 C 2 3  0 D 2 3  0 E 2 3  0 F 2 3 ;-1st+4th 64K banks (mirror of above)

Actually, that's more like an Inicron expansion, as than a dk'tronics one.

0040: 0 0 0 0  1 1 1 1  2 2 2 2  3 3 3 3 ;\

00E0: 8 8 8 8  9 9 9 9  A A A A  B B B B ; with MAPMOD and then passed to MAP18 directly)
00F0: C C C C  D D D D  E E E E  F F F F ;/

Allows to map any bank to any location (similar to the RAM "mappers" in MSX computers, though accessed through different I/O ports as on the MSX)

Aleste ROMRAM prom (Gate Array 2, ROM/RAM enable)

This 256x4bit PROM assists Gate Array 2 (RAM/ROM enable) 

Inputs:

 A1  PROM1    ;/  not the original value written by the CPU)
 A2  CPU A14  ;\the addressed 16K memory block

 A4  CPU A0
 A5  /MREQ
 A6  /RD
 A7  RAMDIS   ;-RAMDIS pin on expansion port
Outputs:

Aleste VDKEY eprom (video and keyboard)

This 2Kx8bit EPROM is used for Video and Keyboard translation. 

Inputs:
 A0..A8   9bit scanline counter
 A9       HSYNC period (duration counted as 1M div 8 or so)
 A10      not used (wired to GND)
Outputs:
 D0       video SYNC* (hsync+vsync, passed to monitor SYNC)
 D1       video HY*   (vsync, passed to ppi)
 D2       video SINT* (probably the 300Hz interrupt?)
 D3       not used    (not connected) (bit3 is always "1" in ROM-image)
 D4..D7   keyboard

            (ie. "A A F B B B A A  8 8 8 8 8 8 8 8" etc.)
            (that is, SYNC is inverted during HSYNC period)
  • Note: The "." entries contain a value of 9. (The "." is just used instead of "9" to make the other entries more visible)

Aleste AF prom (Floppy)

This 32x8bit PROM assists the floppy disk controller. It's related to low-level signals recorded on the floppy (nothing to care about when accessing the floppy I/O ports). 

0000: 11 11 02 03 03 04 05 06  0B 0D 0C 0E 0F 0F 00 01
0010: 11 12 03 04 05 06 07 08  09 0A 0B 0C 0D 0E 0F 00

In Amstrad's DDI-1 disk interface, the uPD765 floppy controller is assisted by a FDC9229BT chip. The Aleste has a russian equivalent to the uPF765, but none to the FDC9229BT - instead, that portion is handled by the PROM and separate logic chips.
