Re: Card ID Help: Generic SCSI?

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
