I remember reading about the Dallas RTC (probably on the old "forum that was")... can you give me more info? I only have 1571 and uIEC so I don't have any RTC capability, and would like to add that feature to my C128 by some method (like that empty [EP]ROM socket). Here is some documentation and a usage example (it is designed with a microcontroller in mind, but I found it useful anyway).

Hi Miro, I've seen on your website that you still plan to support Dallas Smartwatch (DS1216E) as a solution for RTC: have you already done some work for it?
I own one (bought new from DigiKey), I plugged it into the internal function rom socket U36 and wrote some (ugly) assembly code to support reading and setting time, but It never worked; I don't know if I'm doing something wrong (which could certainly be the case due to my limited skill with 8502 assembler) or if the IC just doesn't work.

Keep up the good work Miro, my C128 is eager to try it!

Yeah, it's a shame, but due to its massive amount of content I think that translating / producing an international version would be an overwhelming task for anyone!
And, for the rest of the world, there's always the more than excellent Commodore Free magazine!

I'm following C=FG since the beginning: layout quality and contents are amazing! It so looks like professional work!

I was thinking about getting that combo (Richard42's DAC + GBS-8200/8220). What is keeping me back is the reported un-reliability of the GBS-8200/8220 with PAL video sources. Version 4 and 5 of that board seem to handle it better though, so I'm very tempted.... Anyway, should I decide for it, what kind of project box is the one depicted? It seems to fit both boards perfectly!

Commodore Free has an ongoing article series about using the stack to call and pass parameters to a function library.

On a side-note, to anyone who would like to assemble this cable, beware that the DIN-8 male connector you should use is the 262-degrees type, not the 270-degrees one. I did this mistake myself, and now it's hard to push into the C=128 and probably doesn't make good contact.

I must add that, while having a single cable for both 80 an 40 column could be really convenient, quality of 40 column signal (composite) is really disappointing. Of course I'm blaming my lack of skill with soldering irons (I found particularly painful soldering wires to the damn DIN-8 connector's pins !) above anything else, but nonetheless...
Next time I'm planning a dual input - dual output harness, using a SCART connector for 80-column and an S-Video one for 40-column. It will require fiddling with the TV remote or controls to switch from 80 to 40 columns, but video quality should drastically improve.

Now I have to update my webpage. Sorry for causing extra-work
