Hi. The 2 EPROMs in my first Rainbow 100 B had hashes identical to the ´rainbow.c´ driver (below). The character generator (unerasable) was also identical. All 3 hashes matched the ZIP on Drive W.

I kept the original archive from Jeff for reference, if someone is interested smile

The Rainbow 100 A dumps would make a nice addition. One proud owner even posted on the DEC section of www.vintage-computer.com and sent me a photo (!) of the 3 ROM chips, but did not respond to later enquiries. Guess he sold his stuff.

None of the 100 A EPROMs (3 x 2732) had serial numbers printed on them. Will re-check the OTP / PROM on the B when time permits.
