While whizzing through the code trying to scrounge verified keyboard scan codes and flags, I found some some buried treasure in the form of an undocumented test routine. It's not that exciting -- it just fills the current file with some sample...
Behold, the result of countless hours of calibrations, problem solving, and wasted filaments: It's not perfect yet. But it's the best out of all the tests I've done so far. Look at all the other failed attempts. I knew going in that calibration would...
Flipper Zero's Kickstarter campaign had a very successful start — on the first day, we raised a whopping $1 million! This number grew, and to date, we have raised nearly $5 million. We’re just shocked by such a result, that’s an amazing achievement....
There are several translation routines found during the file sending stuff that translate one character value into another one. Some we understand, like this one:F4DC sub_F4DC: F4DC 84 7F anda #$7F ; reset high bit F4DE 16 tab F4DF 4F clra F4E0...
From the beginning of my work on the Sol-20 reproduction I wondered what kind of display I would use with it. Of course a small CRT based TV or monitor would be ideal. To that end I put out feelers with my maker mates and even had someone at a local...
Friday, 16:41, 30/12/2022 Tuesday, 18:01, 10/02/2023 Look, my apologies, but I didn't do anything. I just feel like this project log has become just a lump of frustration and uselessness. It is just... I keep looking at the fricking wall...
Total redesign, main objective being to offer more features for same build cost. Main changes listed below.1) New PCB which places key stems in more correct positions when viewed from rear of keybox. This means key stems are no longer in centre...
(for related subject, run-time initialization of ROMs/RAMs, see here) FPGA-based designs often have various read-only stores. Their content can be defined in different ways: Inline in the source code (appropriate for smaller ROMs)Using vendor-specific...
As the amazing online GPRS Weather Station project continues, we have yet another upgrade to the vast array of sensors with a professional analogue wind vane, kindly donated by Vector Instruments. This device will eventually be hooked into the new, upgraded,...
Finally I got my TMS9900 CPU to work enough that I can run original TI-99/4A software on my FPGA based TI-99/4A clone. Below you can find a link to my quick-and-dirty but rather long video about the whole project.Prior to this last working session I...
RAMAll EMZ1001A RAM is implemented on chip, as 64 nibbles, arranged as 4 * 16 matrix, addressed by 2 bit BU (mr_bu) and 4-bit BL (mr_bl) registers. There is really no provision for external RAM, although possibly it could be implemented by INP and...
1440x1440px resolution at 125% scalingWhat the screen would look like on Tetent (but sharper). This already makes me think back to my Windows Vista on PSP days, but I'm mainly imagining the future present of quietly chilling in bed while trimming down...
SummarySalinity, or excess salt in the soil profile, is often called the "silent killer", because of the devastating effect salinity can have on irrigated agriculture. With increasing agricultural irrigation efficiency, there is a risk of salt build-up...
