Was it Gene that was all giddy with nearly completing his Hayes stack? Sorry to burst your bubble buddy but I just found this today: http://www.siconic.com/computers/Hayes%20Interbridge%201.JPG http://www.siconic.com/computers/Hayes%20Interbridge%202.JPG A Hayes Interbridge, in the so-called extruded aluminum (or as the wacky Brits pronounce it by adding a syllable, "aluminium" :) case, with the same form factor as the Chronograph and the Transet. It's apparently an Appletalk bridge, allowing you to locally connect two Appletalk networks or remotely over a modem. Start searching!

What's your coolest ISA card?

by Mzthompson＠aol.com

I don't about cool, but I was tickled to get these cards. I got a box full of ISA Appletalk cards, complete with cables, driver disks, and manuals. When a former employer decided to dispense with the Apple LaserWriter II, I asked it I could have it and the associated cards, cables, etc. They said 'help yourself'. Took a couple after-work evenings just to pull all the cards from various machines and recover all the cables running through our department. Rummaging through our department's vault found the original boxes, manuals, disks, and even a couple complete kits still shrink wrapped. :)) Mike

MS-DOS 3.1 was the highest version that Zenith released for it. The PC-DOs 4 is a private effort by John Beyers <http://members.home.net/johnbeyers/hz100.htm>.

What's your coolest ISA card?

by allain＠panix.com

Not properly an ISA card but I picked up a processor board >from a Kendall Square Research supercomputer in an 'el cheapo' bin (mostly ISA cards) at the MIT Flea. ++++ Revision: The Burroughs/Unisys A-Series silicon emulator. An ISA card set and cool too. Meets all criteria. ++++ John A.

DEC discussion board

by dittman＠dittman.net

I've set up a discussion board for discussing DEC stuff. I think I've got it working right. The board can be found >from a link on http://www.dittman.net/ (linked there so the longer URL doesn't have to be typed the first time). I've set up a basic list of categories and topics, but will add any that sound reasonable. -- Eric Dittman dittman(a)dittman.net

The existing SIMM stick > appears to be 256K x 36 (ie a simple 1MB true parity SIMM @ either 80 or 130ns) I don't know the specified RAM, but I was able to upgrade one with a 1Mx36 SIMM I had sitting around. You'll need at least 4MB to use the WWENG2 image. Also, while the box is open take a look and see if it has the PCMCIA slot. -- Eric Dittman dittman(a)dittman.net

Finds in Houston

by technos＠nerdland.org

I don't know about that. There are plenty of times I would have been as pleased as pie to have someone offer me a eight year old, half working display. Hell, I've paid three figures for Olivetti monitors with horrid burn-in, just soI could have the 'Fix workstation' item off of my mental checklist. The only thing I've learned from years in selling off-lease crap: "For everything that exists on earth, there is someone, somewhere, that will pay you to have it."

DECServer again

To open one up, depress the two latches on the bottom of the unit near the front edge and pop open the top. It isn't easy unless you have three or four hands. If there are SIMM slots the memory can be upgraded. -- Eric Dittman dittman(a)dittman.net

Some of the interesting features of the 8061/8065 were serial address/data bus. They wanted all the pins they could have for external I/O (temp. sensors, injector drivers, etc.) The 8061 used the 8096 instruction set, and the 8065 used the 80196 set. All the chips were proprietary, because of the stupid serial bus. They did however have a chip that would convert the serial bus to a standard Intel address/data bus. But I have never seen one of these outside of Ford. I saw some of the production code that went into these modules: It's a miracle your car starts at all. The hardware/software was "cookie cuttered" into the modules. I.e. this powertrain uses these injectors (hardware/software cut and paste), this crank position sensor (hardware/software cut and paste) this valve timing (software cut and paste). Hey how come this module doesn't work? (As you can probably tell, I worked in module testing!) I believe GM used mostly 68K derived stuff, have no idea about Chrysler. I have a friend that OEMs an after market engine controller to a major aftermarket company. It turns out at least for him, in the beginning, it was easier to figure out the inputs/output to the module, and tweak those values, rather than replicating the functions of the entire controller. He simply placed his module "in-between" the module and the engine, and he could pretty much play at will with certain functions while letting the OEM module handle things he didn't care about.
