Hello All, I was considering buying KryoFlux to read and write Commodore disks. Has anyone done this ? From what I gather you just get the board and you can get the floppy cable and a power supply and power cord. But you need to buy a HD PC floppy drive and then can read the Commodore disks. That is Commodore 1541 disks. Does this sound right ? Jeffrey Brace

VMS Problem, please help..

> >The mms default call to cc is like this: >cc /def=("FEAT_NORMAL","HAVE_CONFIG_H","FEAT_GUI_MOTIF" ) /opt/prefix=all >/include=([.proto],decw$include:) BUFFER.C > Hopefully, it should be possible to get MMS to not optimise when compiling blowfish.c and sha256.c and to optimise when doing the other compilations. I am not familiar enough with MMS to know how to do this.

You may need to compile them with /prefix=all added to the command line if problems show up with names of runtime library functions at link time. However, I suspect that /prefix=all is probably the default anyway. You should be able to use a command line like: $ cc /def=("FEAT_NORMAL","HAVE_CONFIG_H","FEAT_GUI_MOTIF" ) /prefix=all /include=([.proto],decw$include:) /optimise=(inline,nodisjoint) BLOWFISH.C > >Is there further documentation about the compiler optimizations somwhere >available? > There could be slightly more detail about optimisation in the compiler manual but it is highly unlightly that the manual would list additional command line qualifiers that are not documented in the online help. The online help comes with the compiler and normally documents all the available qualifiers. The alpha (and presumably ia64) compilers are quite different to the VAX compilers internally and may have different options relating to optimisation so it is important to consult the correct manual.

Commodore 1591 roms

by dgriffi＠cs.csubak.edu

Does anyone here know anything about the ROMs to the Commodore 1591 floppy drive? The ROM from this prototype was supposedly dumped and sent on to ftp.funet.fi, but it's not there. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

Wow, what a collection! And a Trigger Trace Analyzer, we had one, an expensive option IIRC, a logic analyzer built in to a board in the 8540 reading the emulated processor's signals and states directly. 4 separate triggers IIRC which could be interconnected in all sorts of ways by operating system commands. IIRC the 8540 is based on a rather unusual processor, Signetics 2650. /Jonas

Micro-PROLOG

by spectre＠floodgap.com

Looking for any version of Micro-PROLOG by LPA. This was a modified version of Prolog for small systems and was most notable for translating the typical Horn clause into an almost Lisp-like syntax, but could still do a surprising amount of the language within limitations of the host computer. There were versions for Z80, 8086 and 6502, and possibly others. 6502 preferred but any version, especially with source code, appreciated. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- FORTUNE: You're wise, but not wise enough not to read this sort of drivel. -
