Would this programmer work you suppose? The TL866ii Plus I have doesn't support the 68HC05's, I do have 3 spare fully desoldered EGRETs coming in the mail. When these arrive I can try and see if it can autodetect a compatible chip but no promises.
Mind sharing the ROM? My guess is it's the same ROM with minor changes I've seen a few on Buyee while not this exact type, they are some for companies like Kodak and such. Could also be a region thing as well.
