For sale an old SCSI controller in god cosmetic condition.
Ideal for A2000 or A2500 to use SCSI or ST506 units.
Card tested in A4000 but I haven't got old SCSI unit, so I only managed to recognize the card

  • supports seven SCSI and two ST-506 devices at once
  • the SCSI drives are controlled by the WD 33C93 IC
  • the ST-506 drives are controlled by the Zilog Z80B CPU
  • the 33C93 chip can be controlled by either the 68000 (default) or by the Z80
  • DMA transfers are provided by the custom Commodore 8727 IC featuring a 64 byte FIFO buffer
  • the Z80 CPU has 2 kB RAM to buffer commands from the Amiga, 8 kB PROM with driver routines and 1 kB RAM for storage of variables
  • 50 pin internal SCSI connector
  • DB25 external connector
  • hard disk activity LED connector
  • A-Max II driver

Price: €100 + shipping (+PP)

Declaring interest.
This may be an old thread, but is the A2090 still available? Also, would you happen to know if this card is an autoboot or non-autoboot card?
 
Sorry, it is sold outside Amibay. It wasn't autoboot one. (I think)
Please close thread!
