Thanks, Bill!

So the Z8 is *not* the Z80... and is there *any* compatibility??? This new group setup is something I wanted to try... and no one seems to be posting. So yes, I can look all this up... but I just

Hi Charles. This group is centered around the Z80 Membership Card. The Z8MC was just my clumsy abbreviation. I was not aware that there was such a thing as a Z8 till yesterday. I don’t know anything

The Membership Card is Z80 based. Not sure why Lee went with the Z8 name originally. There is also a Z8 CPU which is more of a microcontroller. There was a BYTE project by Steve Ciarcia many years

From: bill rowe <bill_rowe_ottawa@...> Hi Charles and Bill, Yes, the Z8 is a different (later) Zilog microcomputer. The Z8 was built for smaller controller applications, similar to the Intel

Maybe Lee could do a J11 Membership Card next.

Just joking.? I forgot to put a smiley ? on my post.? It's the chip from a DEC PDP-11 and obviously wouldn't fit in a tin.? I got the idea from

I recently updated the Z80 Membership Card CPU card to rev.B, and the Front Panel card to rev.D. No big changes; but here are the improvements: CPU rev.B The 5v regulator U8 has been flipped upside

Hi Lee,Love it.Do you have prices and availability of a kit yet?Best RegardsPaul?Sent from Samsung tablet.

Easier would be the smaller T-11 as its a more conventional 40pin. Allison

Hi, I've been going over some bugs that Bob Kircher has been encountering. There are 4 bugs identified 1. Some sort of Buffer problem (I need to dig into much earlier emails to recall this

Yes, having A FP should be seamless, least it was on my old Altair when it behaved.? There is no reason why CP/M should not run with a FP.? Also the blinkin lights thing. The Xmodem bug,? That may

With 8080 RST7 is free (bus to 1s using pullups) if you want any other you need to assert that on the bus an octal bus driver with the inputs set to RST3 or 4 is suggested.? RST6 is also in a sorta
