[net.micro] 4 meg Z19->H89 mod?

Robert@sri-unix (07/17/82)

I have been told (by employees of Heath) that other vendors offer a
privately manufactured clone of the Z(or H)19 to H88(or 89)
conversion kit that will allow the Z80 added by that kit to run at a
clock speed of 4 Megahertz instead of the Heath kit's 2 Megahertz.

If anyone has information about such a kit, including the names and
addresses of the vendors, I would appreciate hearing about it.

Please reply to me, not to the list.
