Hi Allison, Welcome back!?? There has been an issue with my implementation of CP/M on both the S100 JAIR board and the Z80MC.I failed to understand one of the drive buffer spaces needed, the space

Hello all... She's back! It been a while and life intervened...? One of the things was getting a Z80MC to play with. I have over a dozen CP/M systems and a few of my own creation both hardware

Bill, not in this version. ? But it could be grown, or another box added to hold it. ?My main purpose was to create a top with buttons, etc. ?The design is in Fusion 360. Aug

I like the cover design too. For my MC, I built a separate LiPO battery/Bluetooth module into another Altoids can and the Z80MC sits in the lid and connects to the battery with a cable. Rich

That looks great - very functional.? Is there room for a battery?

I have created a case (2 versions). ?I started with Noe Ruiz’s snap box thai i use for everything but the kitchen sink. ?The buttons are made in 2 pieces and glued together. ?The top is used with

Hi Tony,?? Please, can you email me directly at joshbensadon at yahoo dotcom.I wish to ask you about what happened over on Cosmacelf forum.?? Josh

To those that may not remember this, the KIM-1 was based on the 6502 in the early 70's. What is even more ironic, is that the Apple II that came after, another 6502 machine (one of my favs) was so

Yanno, this is true about that power. Not from the teletype tho. It was noisy but it had that particular kind of sound. To me in the early 70's into my teen years, when I heard that connected up to a

Hi Lee, Oh yea I was lucky, I made that mistake with the sio, so a bit higher, but with the CPU and the keypad (because like Josh with the sio in the middle) I can fit the 2 board stack (cpu/keys) in

Thanks, guys. It's a challenge to design things small; but it also makes it more interesting.:-) Tony used "low" height IC sockets (-001000). The ones I supply with the kits are "ultra-low" height

Hi Josh! Those sockets are great. Yea when I made the Keyboard and the CPU I got them correct, but when I reordered the sockets for the SIO I messed up and got the 01000 and the 03000 wrong from

It's like a piece of fine machinery.? If you have ever seen an Intertype or Linotype in action, you'll know what I mean.? Even a 4 stroke engine is pretty remarkable...? parts are all moving in

You have to admit this. The front and back view of the Z80MC looks just so cool!

Yea I bet your right on that Josh. Man remembering those days was always so cool. We were all on the ground floor of something we new would change the world. I didnt spend that much time on the Vax,

I would guess that if ever CP/M could run on a VAX, it would be an emulation.??

Well I have to correct myself again here, lol (man it sucks getting old). I had access to a IMSAI 8080 machine back in 77 and then did some work on a VAX 11/780 machine in late 78. The vax was VMS of

Hi Lee, No problem now. Yes Ive got the classic sn63/37 as well, have been doing this a long time like you. This is one of the orders from mouser I have found that is the problem. I had two shipments
