Source for 12.44Mhz crystals?

by derschjo＠mail.msu.edu

Hey all -- While I'm waiting for other parts to arrive for my Tek project... anyone know where to find 12.44Mhz crystals? I acquired an old SSM VB1B video card (with an amazing 64 cols by 16 rows display capability!) that was only mostly-assembled, and the crystal is missing. According to the manual (http://www.classiccmp.org/dunfield/s100c/ssm/vb1b.pdf), it's a 12.44 Mhz part but I can't for the life of me find one anywhere -- even my Google searches mostly return links to the VB1B manual :). (And while we're at it -- my Tek project needs a pair of 39M-ohm resistors... anyone know where to find _these_? I know I can hack one up by putting a few others in series, but it's quite a mess...) Thanks, Josh

Free for the cost of shipping DEC HSJ memory card (I believe)

by jtp＠chinalake.com

I was cleaning out a box of PCMCIA cards and found a gray thin pcmcia memory card with no markings on it. I believe it was used to load some of the HSJs when we got updates. If anyone wants it, I'll drop it in the post (US or Int'l) for the cost of shipping.

Datasheet for ICT 27CX321 EPROM?

by ian_primus＠yahoo.com

I've got a handfull of these things that I've been trying to use. My programmer supports them, and I was hoping that they would have the same pinout as a 2732. At the moment, I'm not so sure. So far, I've had three of these chips in the eraser for a good 45 minutes total. If I set the programmer to the ICT 27CX321, it won't blank check - although reading it in and examining the data produces something composed mostly FF's - though not entirely. If I set the programmer to a generic 2732, it passes blank check. I haven't tried programming one yet - although I suppose I could try to fill one with zeroes. So, I take it that these things have a different pinout? I can't find any data on these. Any help would be appreciated. -Ian

8088 vs. 80c88

The 80c88's were used mostly in small laptops, no? No they wer eused in many stationary apps wherelow power was desired. (small being anything smaller then that Zenith big honker, w/the shocking blue display. It used a *real* 8088 IINM). A CMOS version would be slower and more prone to damage from static electricity. And it would require less power. Off the top of my head I can't think of any desktops that used them, but I may have actually ran into 1 or 2 in my travels. They were not slower, most were as fast or faster. I have a few here. 10mhz and 12mhz parts along with 80C188s (12 and 16mhz).

Can anyone identify these "multipage" terminals?

by tshoppa＠wmata.com

> Anyone recognize these? I've never seen or heard of them before. > <http://www.xmission.com/~legalize/vintage/multipage.jpg> I don't recognize multipage as a brand name, but those sure look a lot like the generic 3270 clones that were everywhere in the 80's and 90's. A picture of a keyboard or the connections on the back of a terminal would confirm my guess. Tim.
