Hi There,

I'm actually projecting and assembling homebrew computers.
Does anyone share the same interest?
From computer kits assembly to an entire CPU homebrew project I love
this hobby :D

This is great.. what is ur impressions about the RC2014 kit. There are
many expansion boards to it...

I assembled an Altair-Duino, PiDP-8 and PiDP-11. Now I'm looking for an IMSAI8080Esp from the high nibble :)

Ya, I have 3 RC2014's (Pro, Zed, Mini - upgraded to the CP/M

version). They

were fun projects.

I also have a 6502 VCF badge that I play with once in a while.

I assembled an Altair-duino and PiDP-8. But both of those were mostly soldering practice since the computer parts are actually software

emulated.

They were easy, but not too easy. No SMD. Allãthrough hole parts.ããThe end result is a really nice CP/M machine (or BASIC machine, dependingãon the options you buy). I took my RC2014Zed and housed it in a nice boxãwith a 9" LCD and made a Kaypro-like setup.ãã AB> I assembled an Altair-Duino, PiDP-8 and PiDP-11.

It runs on a realãZ80 and works like a vintage computer.ããI like my Altair-Duino and PiDP-8, but really I just use them for blinkenlightsãmost of the time.ããã...

I want the scamdemic to be over so that I can stop having to ãwork from home so I can renovate the Man Cave for more vintage computerãspace.ããAll available storage space is already crammed with computers. I only haveãenough desk space to set up 4 vintage systems - 3 of which need to be ãmore-or-less permanent. So one gets swapped out every week or so for ãa different project.ããAnd I have another Kaypro coming soon...ããã...

Closest I get to that is the raspberry pi. What computer kits are you able to obtain? Do tell more on this.ãã./)arkman /\lmighty.ã

Hi Darkman,

those are some "examples" of replicas. I've assembled an Altair-duino
8800, PDP-8, PDP-11 and my own version of an ZX81. Now I'm looking for a IMSAI8080Esp.

--------------------------
Altair

Altair-Duino 8800 https://adwaterandstir.com/altair/ (Very nice replica
for these days... uses arduino)

Altair 8800 Clone https://altairclone.com/ (replica of the original tech)

Altair 8800c Clone https://deramp.com/altair_8800c.html (another great
replica that uses the original tech)

KenBak-1 Replica https://adwaterandstir.com/kenbak/

---
DEC PDPs (uses raspberry pi)

PDP-8 https://obsolescence.wixsite.com/obsolescence/pidp-8
PDP-11 https://obsolescence.wixsite.com/obsolescence/pidp-11

The creator is working on a PDP-10 replica now.

IMSAI 8080 https://thehighnibble.com/imsai8080/ (replica that uses esp32)

---

Digirule2u https://bradsprojects.com/digirule2/ pardon for this offtopic
but it's a small computer in a rule very related to old panel computers
(I ordered one but it's still on its way ...)

---

Does any one know about other replicas?

Ministrel is a replica of ZX81 but it's not being produced for while. http://www.tynemouthsoftware.co.uk/Shop

* BTW... I projected my own one replica of a ZX81 ant it's great...
maybe I'll sell as a kit someday...

Harlequin is a ZX Spectrum Replica http://www.zxdesign.info/harlequin.shtml

I've heard about some apple1 replicas... and I know that the guy from altairduino is creating his own version of an apple 1... --------------------------
