They will soon be available to purchase. You can put whatever 8KByte ROM you want on it!
The board is a meer 1.05 inches deep and has notches for easy removal or mounting (granted a shell is designed). Measuring my own commodore, a board of 1.1875 inches would be flush with the chassis. Also has optional reset switch as suggested by catskull.
My main concern was supporting as many proms, eproms and eeproms as I could since too many are no longer made, but easy to find.
