I've been experimenting with a toner transfer and Toner Reactive Foil (TRF) for remarking chips on my Apple 1 build - namely the MMI proms.
I believe that I can refine my process a little further, but here are my results to date (these proms are some old ones off other hardware that I used to practice the technique).
The basic process is as follows :
- Clean the target MMI proms, removing all original markings
- Produce the artwork
- Print it at correct scale in reverse onto toner transfer paper
- Transfer the toner to the chip
- Place the TRF foil over the toner and fuse it

My artwork will be further refined and the process further tweaked, but I think I'm getting somewhere.
What do you think?
