I build one of those projects from BYTE in about 1984. A project for the Commodore 64. It was just two precision resistor networks connected through CMOS drivers to the address lines of the C64. One network for the lower 8 address lines and one for the upper 8. When the two networks were connected to the XY inputs of a oscilloscope, you had a 256 by 256 pixel display of where in memory the 6510 was executing. I was making my living breaking the protection on disk software at the time and this cartridge came in real handy for determining where code was being loaded into memory. I also started writing a TIC-TAC-TOE game for use with the cartridge. The program would place JMP instructions in different parts of memory to draw the TIC-TAC-TOE squares, Xs,and Os on the oscilloscope. Sort of a vector graphic version. I had alot more time on my hands back then. ========================================= Doug Coward dcoward(a)pressstart.com Senior Software Engineer Press Start Inc.

Quite a If they're the later models with the rectangular eject button in the normal place (rather than earlier models with the parallelogram? (/___/) button) you can just replace them with any old 720K drive. Other than that, you can use external drives; there should be (somewhere on the web) a diagram for making the FDD-to-ST cable. Connectors are available. (Or you can buy a cable from BEST Elect. in San Jose(?) or elsewhere.) And while we're on the subject, has anyone figured out how to use a standard PC/Teac fdd with a mac? --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Insanely Great

It allowed you to type >with one hand. I remember a PC keyboard replacement that was a one-handed keyboard; it used combinations of buttons to replace all the individual letter keys. I remember thinking it was a good idea, and could be used perhaps (or expanded) for other languages like chinese. Anyway, I seem to remember that it was supposed to be easy to learn. Was it? was it the "Chord" keyboard Sam mentioned, or were there others? Are they still available? Is there any advantage? I'm thinking that it would be a good option for situations where a) space is at a premium (laptops) or b) one's hands are engaged elsewhere. (No, I wasn't thinking of *that*! (I'm not that much of a nerd!) I was thinking of vehicle/equipment control sorts of things.) --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

RSX-11M Primer?

by healyzh＠ix.netcom.com

Well, I'm in, I'm excited :^) , and I'm clueless :^( Is there any kind of RSX-11M primer online anywhere? So far I've figured out "TIME" and "DIR" :^) What I'd really like to do is transfer the system from the RL-02 pack to the /73's internal Hard Drive. I'd really like to slim the /73 down, and the RL02 is more than twice as big as the /73 :^) Zane | Zane H.

PDP-11/73 Boots!!!!

by healyzh＠ix.netcom.com

YAHOO!!!! Thanks to the bootstrap that Tim posted I just booted one of my SMS-1000's off of a RL-02. Turns out it's running "RSX-11M 4.2 BL38B", on the down side I've no idea what the login/password are :^( BTW neither SMS-1000 that I've got has boot ROM's that support a RL02. Not surprising since their S/N's seem to be sequencial :^) Zane | Zane H.

Larry's Excellent Adventure

by foxnhare＠goldrush.com

Haven't had all that much thrifting lately so I have been pretty quiet. I just wanted to post about my jaunt to San Jose last weekend (for those of you not familiar with the region it is pretty much the center of what they call Silicon Valley). First off for those of you who live in the area, you guys drive like maniacs, you know there things called 'speed limits' and many cars are equipped with a 'turn signal' to signal switching lanes. Ok back on topic (if this were very much on topic), while my wife attended the 'Rubberama Rubber Stamp Show' I had the opportunity to check out 'theTech Museum of Innovation' It was very facinating obviously it has been supported by Intel with a mock-up clean room displaying the processes of making chips with examples, machine displays and videos. (you can even buy shiny 'bunny-suit' dolls in the gift shop) Also there was a rather interesting section on robotics, some on recycling, and a section devoted to space exploration but save for a few snapshots (of Woz's workbench and HP's garage) there was not any classic computers to be seen *sigh*. Oh and an internet/computer instruction center too, but I didn't spend much time there. The said some of the exhibits are on the new building (scheduled to be opened October 31st) so if you are thinking of visiting in the future you may want to wait. I did pick up an interesting souviner, a small hunk of processed silicon (looks like leftovers from the vats where they form the ingots). I only bought one and now think I sould have stocked up - for stocking stuffers and the like (Hey, if any of you volunteer there or go by the museum, could I get you to purchase some more for me? please???) So six bucks gets you adult admission. If you are interested in the chip manufacturing process and want to see some robots and stuff I think it's worth the money (and if you are too cheap for $6.00 at least you can see the billiard ball display just outside the entrance.) Oh, here's the web address for more details on the place: http://www.thetech.org/ -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-

Microprocessors and who made them?

by dastar＠wco.com

Is there a reference somewhere listing all the different microprocessors ever made and who the designers were? Preferrably such a list would include a way (or hint of a way) to contact the designer of said microprocessor. Thanks!
