re request for workslate stuff - have a cassette or two would maybe trade for the box that split the output into serial and parallel - or perhaps just the diagram that shows how to route this without the box - back in its day i saw an article where somebody did this quite easily but i lost track of it

Found a Commodore SX-64 but with a strange problem.

Unfortunately, the > insides are not nearly as easy to get at compared to a standard C64. The SX is, beside some minor changes and a complete different layout just a way ordinay 64 - so no special chips - grap another 64 and exchange the chips - basicly everything may be damaged .... except the RAM - RAM errors are quite rare.

Dallas module battery replacement...

by Ralph.Sobek＠irit.fr

Hi all! Just curious, but are are the prices of these Sun NVRAM timer chips these days? I am looking for a replacement for the old SG Thompson M48T02 chip. Here in France they are on the order of $45-50!! What has happened to last year's $20-28 ? Are the Dallas chips identical to the ST ones, as concerns a Sun? --Ralph -- Dr. Ralph P.

found the front half of an Asante ethernet card

by red＠bears.org

I found---completely at random, in a bin of completely unrelated cruft--- the media interface half of an Asante MacCON/30ie (the ethernet card for the Mac IIsi or SE/30 at a recycler's yesterday. I picked it up for $10 because I thought I remembered somebody on the list was looking for specifically this half, but I can't remember who. It has both UTP and AUI interfaces, and all you need is the PDS half and the cable to connect the two. It's a standard IDC ribbon cable. I haven't counted the pins yet, but it looks as if it could be the same width as a ST506 data cable. If you're out there and you still want it (I should've haggled), contact me off list. ok r.

Found in my inbox

by korpela＠ellie.ssl.berkeley.edu

Although it's not directly classic computer related, I got a kick out of this email I received today. Some of you may enjoy it... Remind me to tell you about the fun I had a few years back with surface mount MIL-SPEC 0 Ohm resistors. (Yes that is a zero). > There is currently a worldwide shortage of very high value ohmite resistors > in the range of 100 - 10,000,000 Mohms (yes, up to 10^13 ohms - they > actually do exist!). The best lead time is ~18-20 weeks. > > If anyone has a resistor of this type, I need the 10^13 ohms value, which I > would borrow for a few tests if possible. Eric

The DOS 10 Commandments (fwd)

by peter＠joules.org

I assume that as DOS is over 10 yrs old this is on topic ;-) -- Regards Pete ---------- Forwarded message ---------- 1) I am thy DOS, thou shall have no OS before me, unless Bill Gates gets a cut of the profits therefrom. 2) Thy DOS is a character based, single user, single tasking, standalone operating system. Thou shall not attempt to make DOS network, multitask, or display a graphical user interface, for that would be a gross hack . 3) Thy hard disk shall never have more than 1024 sectors. You don't need that much space anyway. 4) Thy application program and data shall all fit in 640K of RAM. After all, it's ten times what you had on a CP/M machine. Keep holy this 640K of RAM, and clutter it not with device drivers, memory managers, or other things that might make thy computer useful. 5) Thou shall use the one true slash character to separate thy directory path. Thou shall learn and love this character, even though it appears on no typewriter keyboard, and is unfamiliar. Standardization on where that character is located on a computer keyboard is right out . 6) Thou shall edit and shuffle the sacred lines of CONFIG.SYS and AUTOEXEC.BAT until DOS functions adequately for the likes of you. Giving up in disgust is not allowed. 7) Know in thy heart that DOS shall always maintain backward compatibility to the holy 2.0 version, blindly ignoring opportunities to become compatible with things created in the latter half of this century. But you can still run WordStar 1.0 8) Improve thy memory, for thou shall be required to remember that JD031792.LTR is the letter that you wrote to Jane Doe three years ago regarding the tax deductible contribution that you made to her organization. The IRS Auditor shall be impressed by thy memory as he stands over you demanding proof . 9) Pick carefully the names of thy directories, for renaming them shall be mighty difficult. While you're at it, don't try to relocate branches of the directory tree, either. 10) Learn well the Vulcan Nerve Pinch (ctrl-alt-del) for it shall be thy saviour on many an occasion. Believe in thy heart that everyone reboots their OS to solve problems that shouldn't occur in the first place.

Calcomp Drawing Card

by mmcfadden＠cmh.edu

I just found in the original box, minus software and documentation a "Calcomp Drawing Card". It is a full length ISA card with an attached daughter card that can display 16 or 256 colors of a palette of 4 million colors at 1024 X 768. The ROM chips on the board are all labeled 1987. It says it works with IBM PC AT. Anybody know anything more? I tried a google and altavista search but only hit was for a grayscale version. Mike mmcfadden(a)cmh.edu
