Finishing Touches
Log from Ender 3 Artifex Edition
I opted to get an SKR Mini E3 V3 as a replacement board and I am just putting the finishing touches on the firmware changes to get it ready for public release.

[M - E3] Room
Log from SecSavr Sublime [gd0036]
So I started to write the dependencies of components down and realised that Room > Frame > Gantry > Slime is wayyyyyy better than trying to go the other way around. Thus, I'm currently modelling the location in the room where the printer is going. I...

Eureka!
Log from Commodore CHESSmate Reproduction
After I convinced myself that the emulator was probably OK, I turned back to the ROM. But after I found yet another ROM image online, and it turned out to be identical to the other three, I have to rule out bad ROM as well. Just as well as I was...

Squeezing the code because 85 bytes is too many...
Log from Joy232
I have started to squeeze the hook code. This can be done by merging the start, stop and data bits into a 16 bit register and use the same loop to transmit all the bits from the RS232 character (i.e. 10 bits). It also has a positive side effect that...

Lens and Screen mounted for Version B2
Log from Arduino Glasses a HMD for Multimeter
I found the time to try 2 lenses. Google cardboard lens and another one laying around here.The google lens is not the best choice, so I will try a few other lensesHere now the B2 version with lens and screen mounted. Works but I'm still not satisfied...

Gray counter
Log from YGREC8
20200810: see 122. Updated Gray Counter for the rest of the story !I must make a Gray code counter ! It is not obvious why but it's an important piece of circuitry that is required by the debug/test port... Have a look there for some background :4. The...

20230214a -- Memory, cont.
Log from ROM Disassembly - AlphaSmart Pro
Operating under the current assumption that RAM is 32 KiB banked at address 0000-7fff, with the first 256 bytes masked off by special function registers and internal SRAM, some other code sections of interest were found. E.g.:ED00 loc_ED00: ED00...

New retro computer project board using the TinyFPGA B2
Log from TinyFPGA B-Series
I've posted details about a new retro-computer project board using the TinyFPGA B2. Check it out on the Hackaday.io project page: https://hackaday.io/project/29526-tinyfpga-computer-project-board

ROM checksum code
Log from Re-UD-80 - a larger display for Epson PX-4 / PX-8
The 5.21E ROM works file with the current board, but the 7.11A ROM uses a different pin for the vertical sync signal. This can be fixed, but then the 5.21E ROM results in no display. Rather than fixing the hardware (with a jumper to be changed when the...

B1, B2 and (most of) its components arrived in the mail.
Log from 74HCT6526
I've cleared my agenda (it wasn't too busy anyway) this weekend to assemble both B1 and B2, which correspond to both TIMERS and CREG. I'm still missing some ICs (mainly, some 4-bit binary counters) that should arrive soon, so I won't be able to carry...

OPS ENUMERATED - Draft
Log from TIS-100 (Geiger)
This represents a complete OPCODE list with 14 Constants (int values) available and 10 Labels (byte values) available for creating subroutines. Constants were favored over Labels, but this is up for evaluation. NOP and HCF were both added to the official...

Control Board FPGA Pinout
Log from BARCO NX-4 GROUP REVERSING ADVENTURE
I might be missing a few connections yet which I'll correct as I come across them, but here is the pinout of the XC3S250E FPGA on the control board. Note that the SRAM and the Flash share an interface bus. Also note that the JTAG interface...
