No. On VCFED, I saw a post that said there were 176 256Kbit chips on
it. I work the math as:
11 chips == 256Kbytes (with ECC)
44 chips == 1MBytes (with ECC)
176 chips == 4MBytes (with ECC).
I have no idea where 11MB came from.

The /34 KD11-E is a two-board set with an ALU implemented with 74181
chips. This J-11 board is definitely 3rd party and much later.
