I presume someone is fiddling with the theme....

So while you're at it, can you up the contrast level for the icons representing topics with new/unread articles vs. ones that are "caught-up" ? It's now very hard to make out...

Thanks,

My next goal is to get started on the command parser and monitor. Id like some input on what you find essential from a good monitor/disassembler.

I went through this myself when doing my own Ruby project a while back. What I found was that it was hard to not let my past experiences on the Apple ...

Floating point is (IMO) badly handled by many languages (and programmers!) It's hard to get right and harder to please everyone with your interpretation of right ...

In the C world we have floor(), ceil() and rint(). Floor truncates to the nearest integer down, ceil truncates to an integer up and ...

I'm not convinced you need full duplex for a little project like this.

Or maybe I'm just justifying my own half-duplex minimal SBC... which runs at 38400 baud with the 6507 running from a 2Mhz xtal.

I can download code into it via my terminal program by making the receiving side not echo ...

I'd like my BASIC interpreter (see previous post ) to fit into 8K but after working on it for a few days, I've only managed to reduce it by about 100 bytes. I need to eliminate another 280.

I'm considering offering a bounty for patches that save space. It would mostly be for fun, with the bounty ...

Uh...I’ll get my coat and quietly exit. :D
With puns like that I was hoping you'd be here all week.

@Gordon, thanks for the details. I was going to ask how you achieved that many digits, as I was suspecting the Spigot algorithm. I'd considered using that to avoid arbitrary precision arithmetic ...

Maybe a Pi challenge.... :-)

Although I suspect the good folks over at stardot will beat just about anyting.... This is my '816 system generating the first 1000 digits. The program is wrtten in BCPL and takes almost 500 seconds to run on my 16Mhz system...
Makes me wonder how much faster that ...

I was rummaging through my vast archives of old code today, as one will, when I found that I've already written the file server and download client for the proposed online facility.
I tested the file server and downloader parts of this package with a dynamic DNS service, and found it to be working ...

The core reads and writes of my FAT32 CF card system are between the card and a couple of page-aligned pages in memory, and the code requires 13 clocks per byte, plus a little overhead, giving a maximum transfer rate of ~70kB/s per MHz (I'm using a 1.8432MHz clock). In some cases, the read rate is ...

The project will be on a PCB, all through hole, aim is to get 4Mhz.

Trying to get my head around address decoding for 1M or 2M or RAM.

FWIW: My project is all through hole, 2-sided board and runs at 16MHz. I use 2 GALs. It only has 512KB of RAM though - I thought long and hard about how much ...

Hi guys

I've setting up an SBC design at the moment which will involve an SAA5050 Teletext Character Generator IC as part of it's video circuitry.
That chip requires two inputs: 6MHz to the TR6 pin and 1MHz F1 pin.
PHI2 is going to be switchable between 16MHz and 8MHz from a 32MHZ Source ...

When doing terminal I/O support for PDP11 BASIC I did extensive research into ANSI/VT character sequences. Loads and loads of available documentation missed huge chunks out, I wanted a COMPLETE list of ABSO. LUTELY. *EVERYTHING* - *INCLUDING* gaps. Not just "we've omitted some stuff we oh so ...

I suppose where you draw the line depends on how much of a retro purist you are. I know putting a Linux SBC in a case and running a 6502 emulator on it wouldn't work for me. It would have telltale signs of a Linux computer running an emulator, however hard I tried to hide them.

I'm with you there ...
