Correction:
If you were referring to the two CDROM Driver EPROMs (in sockets U34 and U35) on the CDTV then they use
27C1000 EPROMs.
In the parts list (see partslist-p1.png) they are listed as:
252606-01 ROM CDROM DRIVER, ODD U35
252607-01 ROM CDROM DRIVER, EVEN U34
In the schematic (see schematics-p7-dmac-scsi.png) the parts are shown as 27C1000 EPROMs.
If you check the datasheet, it's probably also possible to use a
27C1001 but you would have to make an adapter to swap pins 2 and pins 24 (or bend these pins up and connect wires to socket) as these are the only pins that differ:
Code:
27C1000 27C1001
pin 2 A16 ¬OE
pin 24 ¬OE A16
