Hi;
I'm hoping someone can help me identify an Apple II expansion card. I
think it is a generic SCSI card of the Rev. C variety. If someone could
confirm or refute this, it would be appreciated. There is no printing
on the front or back of the card, other than the component IDs.
An image of the card can be found here:
<http://apple2.cometdust.ca/a2_cards/a2_cards-Pages/Image27.html>
This card has the following ICs:
U7 74LS273
U9 74LS74
U13 74LS240
U4 74LS138
U6 74LS00
U11 74LS08
U16 74LS74
U3 PAL20L10ACNS / 732194
U5 74LS133
U10 74LS244
U14 74LS244
U15 74LS09
U2 HM3-2064-5 / 8547FE 418
U8 27C64 (EPROM)
U12 74LS245
U1 5380
-------------
For comparison, the Apple II Rev. C SCSI Card has:
U1C 74LS240
U1E 74LS14
U2A 74LS133
U2B 74LS08
U2D 74LS138
U2E 74LS138
U3A 2764 (Apple 341-0437-A)
U3C 16L88-2 (Apple 341-0415)
U3D 16L88-2 (Apple 341-0416)
U3E 74LS273
U5A 5380
U5C 6264
U5E 74LS14
U6C 74LS32
U6D 74LS74
U6E 74LS74
Any help would be appreciated.
Thanks,
Brian
