If Derek is busy, I'm not. I offered to make a run in 2014. I'd be happy to do one now but I defer to Derek.

Hi Richard. LONG time no see! *hugs*

All we need is for TT and Lau to register, and the circle will be complete.

Eeeexcellent!

Thank you, Marcel.

Does anyone have an annotated disassembly of the SGC 2.49 ROM? If not, it would be interesting and useful to walk through it here in the group to see in detail how the SGC starts up, moves data, reconfigures things, edits various versions of QDOS and Minerva, and then restarts the system. Does anyon...

Today I received 10x Freescale 68VZ328 33MHz parts. They're interesting! Built in DRAM refresh manager, UARTs, SPI, RTC, and the funkytown chip select logic that can define areas of memory as 8- or 16-bit accessible. That chip select logic also allows programmed generation of DTACK. They're for an S...

Funny thing. I have a QL with two SD slots. I realised I can lower the right microdrive square bump to be level with the keyboard case cover, and and going to start on that mod this weekend. That is a really neat effect, and I would love it if you made a video showing some of the techniques you used...

As a survivor of last week in Texas when so many around me didn't... I'm half way between laughing and crying.

My instinct here would be to use an ATF1502 as decoder and IRQ hold. It has the capacity to do all address decoding for chip selects for RAM and ethernet, a single flipflop to hold interrupts until they're enabled. If reconfiguring the CP2200 is a single write cycle, it could be triggered by /WR and...
