Someone on comp.os.cpm pointed this out. I don't recall anyone doing so here. http://www.radioshackcatalogs.com/. Mmm...

Rockwell PPS-4 info (was 8008 v. 4004...)

That tuner was designed and built in Milwaukee by a company that a friend of mine worked for. At the time, several of his friends built units up from leftovers from the production run.

In search of some RAM.

by kerobaros＠gmail.com

I co-manage a gaming center in the mall up here in Cheyenne, Wyoming. I've started setting up a couple older computers around the store as some sort of mini-museum, to try teach the kids that there was indeed something before Halo and WoW. My latest setup is a Power Mac 5500/225, with copies of the old Carmen Sandiego games, and Oregon Trail, and all those other fun things I grew up on. Only problem is that the computer has 48MB of RAM, when it could take up to 128MB, assuming I can lay my hands on the right sticks of RAM. Which is the point of this message! If anyone has a couple of 64MB DIMMs (LowEndMac says the computer wants it in a 60ns EDO flavor), I'd be much obliged if we could work out some sort of deal. If there's something one of you are looking for, I'm sure we could figure out something. I'm sure I have at least a gigabyte of the stuff somewhere in St. Louis, but that's enough hours away that it's not worth it at the moment. Thanks, folks! ~Matt

Canon Cat: what density 3.5"?

by spectre＠floodgap.com

What type of 3.5" floppies are people using in their Cats? Would off-the-shelf double-density suffice? Any special preparation required? -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Nuclear war would really set back cable. -- Ted Turner ---------------------

CPU/Hardware info for Seiko UC-2000

by derschjo＠msu.edu

Hi all -- Got myself a Seiko UC-2000 ("Wrist Information System") w/UC-2200 keyboard/terminal. The UC-2000 is a souped-up digital watch with a dot-matrix display, and the Keyboard unit is basically a computer that uses the watch as a display. (So it's more or less like the old Sharp/Casio BASIC programmables, only it uses a watch for a display instead of something built-in...) But the watch itself is _also_ a small computer -- one can upload small binary programs from the Keyboard unit to the watch. From the little information I've been able to find, it has 2k of RAM, 7k of ROM, and a 4-bit CPU running at 32kHz (yes, kHz). Does anyone know anything about the CPU? It'd be fun to write some little programs for this (assuming I can work out how to get them transferred over...) (See http://www.pocketcalculatorshow.com/nerdwatch/fun2.html for a brief description of the UC-2000 and others in the same family...) Josh

resurrecting a Zilog System 8000

by lehmann＠ans-netz.de

Hi, as someone might remember, I've got some Zilog System 8000 equipment and over the last days I've started resurrecting it. I thought - maybe someone feels interested in the story as well ;) 2 days ago I've built my "custom" frontpanel (just a transition solution) with the remaining stuff I had at home. The "original-like" push button I tried to get in my local electronic distributor was out of stock. So I reused an old circuit board, 11+40 ohm resisitor to get the needed 51 ohm and so on... ;-) The final version will contain the "original-like" push buttons, the LED banks and so on. It will be mounted then at the same position where the original panel sits. When it is then hidden behind the front door it will look nearly like the original one. At least, thats the plan. Until then: http://pics.pofo.de/gallery/v/S8000/Repair/P1070180.JPG.html http://pics.pofo.de/gallery/v/S8000/Repair/P1070181.JPG.html After this was done, I've used an old PC-AT PSU for supplying the required power to the backplane ("POWERFAIL" cable ignored): http://pics.pofo.de/gallery/v/S8000/Repair/P1070182.JPG.html And then put back all together, huck up a nulmodem cable to my PC and - yeah The firmware got loaded and the usual START message was printed: http://pics.pofo.de/gallery/v/S8000/Repair/P1070183.JPG.html http://pics.pofo.de/gallery/v/S8000/Repair/P1070186.JPG.html Pressing the NMI/START switch on my glamorous frontpanel brings up an immediate FATAL ERROR: S8000 Monitor 1.2 - Press START to Load System P *** ERROR #0000 *** FATAL ERROR [ Reading the hardware ref. manual - this means no external RAM - of course, I still don't have the 1MB dynamic memory board. :( Connecting the WDC board to the bus leads to a non-startable system having the BUSACK LED on the CPU board permanently on - probably the WDC is broken and spams the system BUS... But at least this was my first step which was done OK I guess ;) -- Oliver Lehmann http://www.pofo.de/ http://wishlist.ans-netz.de/
