FBE ZMF100a Heath H-100 / Zenith Z-100 Memory Modification Kit - NOS.
The ZMF100a is a modification kit which includes all that is needed to modify an "old" motherboard H/Z-100 computer so that one, two, or three sets of industry standard 256K memory chips may be installed directly on the motherboard in place of the 64K memory chips. This permits up to 768K of memory to be installed without using an S100 bus slot.
It includes the circuit board, bus bar for shielding, and instructions.
Please see pictures, and let me know if you have any questions.
These are spare parts that we received in a large Zenith/Heath lot. Due to age, sold as-is.
Thanks for looking.
