I'm not at all convinced I know what you're after. The 20-pin 68HC705 parts
with which I'm familiar are the MC68HC705J1A which comes in a number of
packages, one of which is the ceraminc windowed part. I don't think these are
unavailable in distribution, though I've never gotten one for less than $60.
I think the last place I saw them for sale was Future-Active electronics.
www.future-active.com, though things change, and a quick look didn't show that
part. ISTR that DigiKey had the windowed parts too at one time.

Subject: windowed MC68HSR705J1ACS ?
I am looking for a source for a MC68HSR705J1ACS
Motorola 20 pin DIP
with window (erasable) MC68HC701J1A microprocessor. I have only been
able to find the OTP versions, but would like to find an erasable
one for development. Does anyone know of a source, or have one (or 2)
that you would be willing to sell me?
