Successful upgrade of my SC140 to RomWBW 3.5.1 😃 #8bit #RetroComputing #z80 #z180 #cpm

Successful upgrade of my SC126 to RomWBW 3.5.1 😃 next one on the bench is the SC140. #8bit #RetroComputing #z80 #z180 #cpm

My Commodore 64C just got a lot more fun to use 😃 by adding the brilliant Pi1541 Zero cartridge! What an upgrade from the datasette 📼 #8bit #RetroComputing #c64

Slightly more retro than usual 😀 but fun! And kudos to those 17th and 18th century engineers for figuring this out …

Intel's 386 processor (1985) moved the x86 architecture to 32 bits, but it needed to be backward compatible with earlier 16 and 8-bit processors. As a result, it needed complicated circuitry for its internal registers: six different circuits for 30 registers. Let's look at the silicon circuits. 1/N

My C64 just got the best digital video output I could ever dream of. The VIC-II-Dizer and an RGB2HDMI bought from c0pperdragon. This is definitely a 5-star rated solution. Excellent. (unfortunately the photo of the screen doesn't really capture how good the picture is) #c64 #8bit #retrocomputing

This is so much better than PDF files 😃 got this original handbook today! The book is from 1980 but in good condition. #hp41cv

My latest wall decoration 😃

I am happy that I managed to revive this HP-41CV which I picked up very cheap because of heavy leakage from the batteries. Thorough cleaning and a new battery/port bay and screw mounts made the difference! Have to mention this HP-41CV is 41 years old 😃 #RetroComputing #vintagecalculators #hp #hp41c

"Fly me to the moon" - the Apollo Guidance Computer was basically build on this resistor-transistor NOR gate, each IC containing 3 or 6 transistors, forming either a single 3-input NOR chip, or a double 3-input NOR chip. #RetroComputing #Apollo #AGC

I really needed this one in my Linux bash. Maybe I do a little too much CP/M stuff 😀 alias era='rm' #RetroComputing #cpm #z80

XMAS light time! NAND gate lights up when one or both inputs are low. No light when both inputs are high. #RetroComputing #digital #logic

Test run of Spectrum Forth on The Spectrum, seems to run as expected 😀 #RetroComputing #thespectrum #forth #zxspectrum

Amazon delivered some interesting reads for me, at quite different levels of abstraction 😀 #RetroComputing #z80 #thespectrum #zxspectrum

My favourite CP/M 2.2 system. Why? Simplicity. SC114 + SC139 + SC145 #8bit #RetroComputing #zilog #z80 #cpm

Got this 1982 HP-10C today in very good condition 😃 I didn't have one in my "Voyager" collection so happy to find such a good one 💎 #RetroComputing #hp #vintagecalculators

I love being a "full-stack developer" in retrocomputing 😂 #RetroComputing #basic

Latest firmware update 1.0.2 installed in The Spectrum. It was a very easy task 😀 #RetroComputing #thespectrum #zxspectrum #z80

The Spectrum is loaded with some real ROM images 😃 I am happy to find out this is a feature! I am getting more and more impressed by this machine. #RetroComputing #thespectrum #zxspectrum

I recently saw an amazing Navajo rug at the National Gallery of Art. It looks abstract at first, but it is a detailed representation of the Intel Pentium processor. Called "Replica of a Chip", it was created in 1994 by Marilou Schultz, a Navajo/Diné weaver and math teacher. 1/n

Just loaded Zeus assembler on my new speccy. Looks good, hdmi is slightly better than rf modulation 😂 I actually used a 12" B/W TV with my 16k ZX Spectrum back in the days #RetroComputing #thespectrum

ALL content deleted from my X account 😃 leaving the profile dormamt for a while, with a reference to bluesky in the bio, before I deactivate the account completely.

Even the weight of The Spectrum is close to the original. 510 gram versus roughly 570 for the Sinclair ZX Spectrum. #RetroComputing

First run on The Spectrum 😃 I am impressed by the physical appearance, it is a very accurate replica, including the keyboard! It's a long time since I touched the original ZX Spectrum but this is really good and feels the way I remember. #RetroComputing

It's hard to think of a better way to start the weekend, I am really excited to unbox, setup and relive some very good memories from the '80s with The Spectrum computer. I learned so much about programming from my 16K ZX Spectrum back then. #8bit #RetroComputing #Z80 #ZXSpectrum #TheSpectrum

Here's a favorite of mine 😃 the simple but nevertheless very capable SC114 Z80 system running CP/M. Design and kit by Steve Cousins. #RetroComputing #Z80 #CPM

I hope this will be my future platform for posting and reading all kinds of retrocomputing stuff! #8bit #RetroComputing #z80
