All this talk of RM380/480s has prompted me to admit that I own four: 2 x Link 480Z (with one 'beige' twin 5.25 drive) 1 x 380Z (twin 8" drives and winchester) 1 x 380Z (twin 5.25" drives) The 380Z with 8" drives is fairly well loaded: 1) IO 2) CPU/32K #1 3) 32K 4) Hi Res Graphics 5) Winchester #2 6) Analog I/O 7) Network #3 8) Terminator #1 Containing (roll on drums, wait for it tony) a daughter card containing the CPU and the IEEE gubbins (connected to the 'IEEE STD 488 PORT') #2 A 5Mbyte 5.25" unit - unfortunately expired before I acquired it #3 This card has more wire wrap on the 'back' than any other card I've seen that wasn't designed as such The serial number is 35/121003 and the etch dates are 1978 or 1979 with some cards have a cloth sticker of 1980.
