The Aleste 520EX contains five Translation PROMs and EPROMs. They aren't connected as memory, but rather to translate an incoming signals (through address inputs) to to outgoing signals (through data bits).

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

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.
