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 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.

Addresses used when MAPMOD=1: 

0040: 0 0 0 0  1 1 1 1  2 2 2 2  3 3 3 3 ;\
0050: 4 4 4 4  5 5 5 5  6 6 6 6  7 7 7 7 ; first 256K

00C0: 0 0 0 0  1 1 1 1  2 2 2 2  3 3 3 3 ;\second 256K
00D0: 4 4 4 4  5 5 5 5  6 6 6 6  7 7 7 7 ; (fifth bit is handled elsewhere: bit4 is ANDed
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)

 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 counter (clocked by 3CY aka 1M div sth, reset by HY aka VSYNC)
 A9       clocked by 1M div sth
 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

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.
