Last weekend I’ve finished my first CPLD experiment, which (of course) was an project for the C64. This small extension is a GeoRAM compatible RAM extension or a EasyFlash like extension. It’s possible to switch between them via software. In other words you can use it as pure ram or load cartridges in the ram and play (instead of burning eprom modules).

This is only thought as an experiment for me to learn to deal with CPLD. So far it’s working as it should and I’m happy

The used Parts:

• an CPLD: Xilinx XC9572
• 512KiB RAM
• 74hc365 hex buffer/line driver
• a led (with a 1k5 resistor)
• sockets, circuit board and wire

• The files loaded/saved don’t have an load address anymore!
• Simple file browser (cmd compatible)
• Keys reassigned (now matches the function)
• Layout optimized
• Help screen added
• Removed the “Modulgenerator”
• SMON or Multimonitor – your choice

Multiprommer V1.5+1.0 (31.7 KiB, 29. August 2011)

All you need is an ATtiny and a little more, the price should be less than 2 EURO in total.

TextWrangler/BBEdit can open files per sftp (via ssh). This set of tools allows it you to launch edit on a remote server, but your local TextWrangler/BBEdit opens the file.

Get it here: TextWrangler remote control

BBEdit: I haven’t tested it, but it should also work. (I do not own BBEdit)

Fell free to use or improve it:

Update 2011-04-19: Added License and a small improvement.

On OS X and iOS the following table shows you the the size of the types:

char       8 bit
short     16 bit
int       32 bit
long      system size
long long 64 bit

So, on 32bit OS X long is 32 bit, on 64bit OS X it’s 64 bit (unsure for iOS).

NSInteger has always the size of an pointer.

Often asked: “Use int or NSInteger?”. Answer: use NSInteger for pointers, ok usually you should use the pointer type itself, and for everything else use the size you require.

If you want exactly 8 bits, use int8_t for sigend or uint8_t for unsigned, for an integer which has at least those bits, use (u)int_least8_t (analogue for 16/32/64 bits).

Performance: you can use (u)int_fast8_t for the fastest type, which can hold (u)int_8_t. But since (u)int_leastY_t and (u)int_fastY_t are defined as (u)intY_t on OS X and iOS it should make no difference. I use the direct types for when all the bits are used, and the fast types when I don’t use exactly but less bits.

At last: don’t forget the LL or ULL suffix for 64bit constants (you can use (U)INT64_C(num) for always the correct suffix, also for 8/16/32), and the “%lld” in a formatted string for 64bit variables.
(example: NSLog(@"number: %lld", 1LL << 48);)

If you have more information or maybe corrections, please post a comment.

Preferred way of installing: via the Curse Client

It’s desigend for servers, which are no mail servers, and only sends logs, notices and such things. So all other software (may be scripts, used from the web-server) have to use a SMTP server for outgoing mail (e.g. forum).

It can be configred that when sendmail is invoked by a user, that all those mails are going to another address. (the users which calls sendmail is important, not the destination).

example configuration:
[default]
to = "destination@address"
from = "sender@address"
subject = "[Server] [To: %TO%] %SUBJECT%"

You can add more entries in that form, which usernames instead of “default”, in that case all mails sent by that user will be send to the specified address.

The options in detail:

• disabled, optional, defaults to false, if true no mail will be sent (for that user)
• to, required, the destination
• host, optional, the destination host, if omitted the MX record of the to address will be used
• subject, optional, the subject, defaults to “%SUBJECT%” (placeholders: %SUBJECT% the original subject, %TO% the list of original recipients)
• from optional, the sender address, default to “user@hostname”

Files:

• /etc/zeromail.conf
• /usr/sbin/sendmail

You may have problems after uninstalling all MTA software, because some software (e.g. logcheck) requires an installed MTA. I’ve fixed that problem by installing an dummy deb-package, which (says that it) provides an MTA.

This is the way I’m using it on my server and a proof of concept.

Some more explanations in the source.
