Re: Proposal: San Francisco Bay Area user group

I could probably fill up a whole table if I brought more than one machine... would need to dig up another screen from somewhere though. I feel like half a table (4' width) would probably be nicer though. What are we aiming for here? One of each machine? Lots so people can play with them? 1x usable ...

Re: Proposal: San Francisco Bay Area user group

Both my BBC Master and my A3020 are fitted with Econet and I think I might even have a cable or two. I always wished someone would make an Econet-Ethernet bridge, for teleporting Econet signals over the internet via a central server. Then we could all share one single global Econet. ...might be imp...

Re: Proposal: San Francisco Bay Area user group

Hey there. I'm in Woodside CA and have a BBC Master 128 (working great), a B+ (untested but probably fine), an Acorn A3020 (should be fine), and a multi-standard Sony PVM for displaying things on. Good news! I just heard back. Looks like we are accepted to exhibit at VCF West at the Computer Histor...

Re: HostFS and microcontrollers?

I'd be very interested to see your scope traces that show why things are breaking with a non-FTDI adapter! I assume something to do with RTS timing, or non-FTDI adapters sampling CTS at the wrong time? I'm running the following test program: 10 REPEAT 20 TIME=0 30 *SAVE OS C000 +100 40 T=TIME 50 PR...

This repeated sequence is waiting for the start bit. It will last 8 cycles (4 us) and is repeated 13 times, giving a total of 52us. If a start bit is not detected, then CTS is dropped: LDA #0 \ if no start bit detected, reset CTS STA upiob TXA \ transfer buffer pointer to A CLI \ re-enable IRQ RTS ...

The user port route works fairly well, especially if you're using the ATMEGA32U4, which runs at 5V and accepts TTL levels on its inputs (but can also produce 3.3V outputs for USB), although I had synchronization issues with HostFS:UPURS / UPURSFS; I'm not sure if that was due to a bug in my code or...
