I'm just about to offer up an A4000 tower. Specs:
A4000, 2mb CHIP RAM, KS3.1
Microniks tower case
Micronics ZorroIII expander board
WarpEngine040 @ 40MHz c/w 128MB RAM (Cyberstorm 060 is only 13% faster than the WarpEngine...)
HP 2gb SCSI disk (on the Warp Engine on-board SCSI controller
C64/3D gfx card
X-Surf network card
VLAB card
Nexus SCSI-2 card with SCSI CD-RW
Tower case has 6 x 5.25" front accesible drive bays, 4 x 3.5" bays
Expander board has 7 Zorro III slots, 2 Video slots, 5 ISA slots (in line with Z3 slots)
Debating whether to add
DDS-2 DAT drive
second CD-ROM
GG2+ bridgecard (the very card reviewed by me in AUI), to access the ISA slots, plus NE2000 compatible NIC and modem.
This was being prepared for ebay - 10p listing day on Thursday - but if I get a buyer :-)
Whereabouts in the world are you?
