Today I decided to convert the contents of the ROM chip I had dumped with my EPROM reader to a .CRT file, using VICE’s cartconv tool:
cartconv.exe -r -t normal -i "input.bin" -o "output.crt" -n "C64-Diagnostic-ROM-1"
I then tested the .CRT in VICE, which seemed to work quite well indeed:
There was a bug in my reader for which I was accidentally missing the first byte of the ROM within a dump: the bug is also appearing in the video I had shared. However, such bug has since been fixed and I have been obtaining 100% consistent results while dumping the ROM over and over again, which is great news.
One of the PCBs I had manufactured a while ago, referred to as IECHost “white knight” version, has recently come to life as I decided to put one together.
I designed this version for a couple of reasons, one being the use of a different DIN connector for the IEC bus, that I was able to source from a new stock. Nonetheless, if a 3D-printed case was ever made for the vanilla version of IECHost, it would be reusable for this one too.
Note that this build is NOT available for sale: this is my own build. In fact, I keep one build of each and every device I ever designed, along with prototypes that were never available to the general public. However, those interested in one can just ask for it when ordering for an IECHost DIY kit.
As part of the sorting out exercise I am going through, I brought back in good shape the DC2N2 test bed I had put together in 2013/2014. Not only I did tweaks to the wiring of the circuit, but I also did a few firmware changes.
As I was at it, I also monitored current consumption while dumping tapes, similarly to what I did a while back for DC2N3, DC2N4-LC, and DC2N5-LC. The figure is pretty small, peaking at 140 milliamps.
Stay tuned for more as I bring more test beds back in good shape!
