It's a long time since I've looked at this but If you follow the patch process at :

https://github.com/C4ptFuture/cdtv-os235patch

Then you should end up with two distinct files :

CDTV_v2_35_U34_Even.bin
CDTV_v2_35_U35_Odd.bin

That are written as-as to individual EPROMS.

As supaduper says, select M27C1001 in the software, provided you are using a TL866 in conjunction with the adapter. It should say words to that effect on the back of the adapter ;)

As a side note, this is TL866(/2 Plus) specific. Other fancy programmers, and potentially the newer XGECU T48 (TL866-3G) / T56 "might" support the M27C1000 without the need for the adapter, but the TL866/2 was the common programmer at that time. Perhaps someone with a T48 / T56 could confirm direct support without the need for that Heath Robinson adapter ?
