Well... when I ran a BBS on my Amiga the costs would dwarf ALL these.
A2000 £750 (good price at time)
GVP SCSI and 40Mb Quantum £750 (ouch)
GVP 28mhz 030 & 8Mb Ram £500 2nd hand (bargain!!)
5x USR HST 16.8 modems at £400 each £2000
2Gb of SCSI Hard Disk - FREE from co-sysop's workplace
A1200 for Games with GVP 030 £300+£200 = £500
Well theres £4500 without starting.. then there was the A500 before it all...
