Yup, they made desktop PC-compatibles for a while. I remember a dealer in College Park, MD selling them (Software'n'Things if anyone else out there remembers them; to the best of my knowledge they aren't operating under that name anymore if at all). One of the big selling points was that they were upgradable by virtue of the passive backplane. Buy an XT-compatible now, later on you can upgrade to an AT-compatible just by swapping the CPU card for the '286 flavor. BTW Doug, is that your face I saw gazing up at me from this morning's San Jose Mercury News? If not, there's some guy calling himself Doug Salot who has some stuff in his collection that's an awful lot like things you've mentioned on this list. -Frank McConnell

When someone says Line Printer I think of something with the type on a chain (or a drum) and the ribbon in front of the paper, and then a bunch of hammers behind the paper. When the right character is in front of the right position, the printer fires the hammer for that position and pushes the paper up against the ribbon and chain/drum. But the real definition is in how much data you have to send to the printer to get it printing. If you have to give it a full line to get it going then it's a line printer. If you only have to give it a character to make it print then it isn't. -Frank McConnell

>Unless the Z80 option includes a pod that attaches to a Z80, then you Is this "pod" something that clamps over an installed CPU? There is a test socket for something like this. May attach to an edge connector at the back marked "Microprocessor Probe".

Freebie Update

Dave Jenner has bowed out on all items in the list I posted. Sam has claimed the DEC books. The programming card and Everex book are still available, as are all the hardware items.

Anyone (finger points at Allison) have any stories about them? It looked fairly serious. William Donzelli william(a)ans.net

microprocessors - was Re[2]: Replies to various threads

by allisonp＠world.std.com

<> I missed a few... D11, T11, 68030, HP Saturn, 7811 (if we're counting <> embedded chips that we've never programmed :-)), 8x305, Z8, probably <I didn't quite mean that :-) I was just interested to note that some <micros that were once well-known aren't well-represented in your list, o <Allison's, or mine. Only one occurrence of the 9900, no F8, only one <Cosmac, ... Perhaps three people is just too small a sample to show al <of the ones that faded from popularity (and maybe nobody else here is <interested :-)) Not a lot of DSPs either, though of course they're more <"modern". Well the F8 while known was not hobbiest fodder being aimed at embedded systems. Same can eb said for z8. The 9900 as I refer to it was not the TI99/4a(have those too) but a Technico SBC, due to a lack of TI support it was not that popular. However the TI99/4a is still quite popular. Others I've worked with 78pg11(uCOM78) were aimed at embedded applications. I might add that my time as a product engineer at NEC in the early '80s had me designing in that part as well as supporting it along with ucom4 and ucom75 4bit micros. The RCA1802 was sort of a square egg. It had popularity for a short while. People lost interest after that, partly as RCA discontinued it by the mid 80s. Also because it was slow and had a relatively poor(primitive) instruction set and a total lack of high level languages other than tinybasic. The advent of more complete systems like apple and trs80 and decreasing prices helped focus the market on two key players 6502 and z80 and it would remain that way until the 68000 and 8088(x86) would displace them.
