PS/1 was idea of "value" read: stripped down, oddball machines based on ISA design with connector conpirecy add as side dish! And, no memory parity at all! This is why the value bottomed out so rapidly when I traded some parts for a PS/2 2011-M01 stock config but once again in short time again it's gone again to a guy who only needs basic pc. PS/1 carried through a bit for few years then gone that ended in a reasonably decent desktop boxes with fairly standard parts. Jason D. email: jpero(a)cgo.wave.ca Pero, Jason D.

Not usually. I have seen few good designed machines go kooky when it finds out holding the non-parity memories even same to ones with user-selectable parity selection. Tis' true if you meant ECC parity but this is really OVERKILL in consumer machines that we're using. My machine is happily running for years on non-parity as long as the memory are top quality kind and cover by life-time warrenty if possible. Mac are doing that for years ever since first Apple II all the way to today's Mac PCI's. If some is very nervous expect to PAY MUCHO more and find some machines that is "1 or 2 steps out of date" designed for error-free operation used in server-level type. Far as I know you will not see that in consumer kind, find them in high-end motherboards in excess of $300 and up. Asus makes superb boards including dual and singles both equipped with either parity or ECC parity. No way with SuperMicro consistently used wasted space and long trace runs Yuk!, Tyan could not make a good boards that works with every parts even iteslf and likes to crash out so often and others far as I know.

Hi guys! I'm envaluating that thinkpad 700C. Sheesh! TFT display /w 1mb XGA on board and someone changed the CPU for 486SLC2 50mhz, 16mb, superb keyboard with trackpoint, working NiMh battery that does quick charge in that deal as you will see later, but! This would be a problem for linux and I'm still prepared to live without PCMCIA feature for little longer. No problem finding inexpensive used 2.5" larger capacity hd with that stupid MCA interface and expect that to work with that series? The current hd is 120mb. No fun being haunted by joke hd for few years that Luddite did. Via internet searches; seemed very low popularity judging by # of enteries, true? Why? History case: Responded to a local newsgroup ad by a owner and picked it up for envaluation/repair as allowed by owner's choice not by my effect. $70 for complete dea, lyet to decide on it. I have repaired this notebook successfully after owner dropped it, cracking the case and tore both display mounting points (left back corner is complete break off, right is partial, only one post broken butthe display shell, hinge pins and it's associated mounting hardware are all dandy. Also these display, floppy, HD and circuit boards (!!) escaped the fate intact and no bad pixel to boot. Now my thoughts: Even if the case is good, I would have a notebook that would not meet all of my needs such as straight 486dx, IDE you got the idea for next notebook replacement for that old limping Luddite. Except for P75, still searching for my collection. Also, I'm not too sure after case is repaired and decides to resell it to recoup some enough $. Or $70 is terrific deal also find another notebook closer to my needs is worthy considering? Gee! I sounded stupid but I'd love to hear from everyone expert on IBM series here first. Thanks! Email or here if other prefers to. Jason D. PS: Compaq LTE 386s/20 given Luddite nickname. email: jpero(a)cgo.wave.ca Pero, Jason D.

Dan: I was more concerned about clarifying the PS/1 as EISA. I must admit I didn't know ANY PS/2s had (E)ISA. That's really interesting... -Mike Dan Rector wrote:

The Micronics part number was M55Pe; the board has an IBM FRU number and even has a nifty full screen 640x400x16 VGA splash screen at bootup (right after the video card splash) that says "IBM PC Server". Nice board. A bit dated, now, but nice all the same. This is all well and dandy but wildly off topic so I'll ask what I'd need to install a floppy disk drive into my currently diskless TRS-80 Model III? I was four when my dad got his new (with 48k and a disk drive) and 11 when he sold it and about 14 before I really got into computers beyond simply being able to drive them and 20 when I picked up a 16k diskless model III at a thrift shop in Walla Walla and I'll just end this run-on sentence here. Suffice to say I have no idea what I'll need. I looked inside my model III and can't even figure how the goofy things mounted, as there seems to be no drive cage. ok r.
