10Episodes   Talkie is in: https://reddwarf.fandom.com/wiki/Talkie_Toaster
11V1 Talkie:
12In   two episodes of Series I, "Future Echoes" and "Waiting for God", Talkie Toaster   appears as a standard 1970s toaster made from stainless steel but with a circular   light on the side which flashes as he speaks, and is voiced by John Lenahan.
13In   "Balance of Power", Series I - Lister eats Krispies and converses with Talkie   Toaster in the sleeping quarters of Red Dwarf
14In a deleted scene from the first   episode of Series II, Talkie Toaster is seen singing a duet with Cat (this scene   can be seen in the special features of the Series II DVD.)
15V2 Talkie:
16In the   Series IV episode "White Hole", Talkie Toaster appears rebuilt by Kryten with   a housing of red plastic, with his name "Talkie Toaster" emblazoned on the side,   and rather more flashing red and green lights (originally from "Box", the computer   in Star Cops) - although they have nothing to do with when he speaks, which is indicated   by the press-down handle that would usually be used to start bread toasting - and   is voiced by David Ross (who originally played Kryten in Series II). The second   novel's description matches his appearance in Series IV.

10Episodes  Talkie is in: https://reddwarf.fandom.com/wiki/Talkie_Toaster
11V1 Talkie:
12In  two episodes of Series I, "Future Echoes" and "Waiting for God", Talkie Toaster  appears as a standard 1970s toaster made from stainless steel but with a circular  light on the side which flashes as he speaks, and is voiced by John Lenahan.
13In  "Balance of Power", Series I - Lister eats Krispies and converses with Talkie  Toaster in the sleeping quarters of Red Dwarf
14In a deleted scene from the first  episode of Series II, Talkie Toaster is seen singing a duet with Cat (this scene  can be seen in the special features of the Series II DVD.)
15V2 Talkie:
16In the  Series IV episode "White Hole", Talkie Toaster appears rebuilt by Kryten with  a housing of red plastic, with his name "Talkie Toaster" emblazoned on the side,  and rather more flashing red and green lights (originally from "Box", the computer  in Star Cops) - although they have nothing to do with when he speaks, which is indicated  by the press-down handle that would usually be used to start bread toasting - and  is voiced by David Ross (who originally played Kryten in Series II). The second  novel's description matches his appearance in Series IV.
