Does anyone know what the difference is between the M8290 and M8291 versions of the CR11? The only version of the CR11 manual online only seems to cover the M8290? Noel

Epay prices seem a little high. $current_job had one years ago and sold it on eBay for $250 (I found the sold listing in a folder ...). I cried a little. It wasn't a fill the floor model - but it had to have had a little "oomph" as it supported 30-40 interactive users all day. I agree with the other posters and the list-boss - if you provide hobbyist pricing I'd be game. You're not going to get far with commercial or "high price just because it's rare but not in demand" pricing. Otherwise, I offer fifty bucks ... :) Fred

Hewlett-Packard 3000, 9000, Itanium (HP-UX & MPE/iX) Servers, Storage Arrays, Replacement Parts, Maintenance, & Disaster back-ups

by jesse＠cypress-tech.com

Man you guys are tough... We sell this old HP stuff, thats what we do. There is no commercial or retail price in 20+ year old items. Its comes down to what we have into it, what others are selling them for, and what the demand is. Jay, I dont recall quoting you a 12920, I went back 3 years on my sent emails and I cant find it. I dont remember what the price or circumstances were. If I had that info, I could understand and explain the price that I quoted you .. but I'm glad you found what you needed... sorry if you were offended. As for me posting an intro on this site.. I have a boat load of older HP stuff and I'm always trying to find homes for. If my info or parts helps someone get the part or system they need, then its a win for everyone. I'm not some spam bot that just sends crap email out, we are a very small company thats been around for 25 years and we have a lot of knowledge with this older 1000, 3000, 9000, & Itanium hardware. Resellers get flack from everyone but small HP vendors like us help keep the wheels of this older HP machine rolling. Try to buy a 25 year old system from HP, they will try to sell you a x86.. :-) Again, it was an intro and if it offended anyone, please accept my apologies* *

Buyer beware

by sales＠elecplus.com

I almost NEVER do this, but please be VERY cautious if dealing with CU Digital in Sadorus, IL. He does have a few model Ms and maybe some Fs, but I STRONGLY suggest you pick them up in person and have a laptop and an adapter to test them before buying.

Change in UNIBUS parity operation (Was: PDP-11/45 RSTS/E boot problem)

by jnc＠mercury.lcs.mit.edu

> Even better, it claims to be able to control whether the memory uses odd > or even parity! (How, for UNIBUS memory, I don't know - there's no way to do > this over the UNIBUS. So this really confused me, as the UNIBUS spec says parity is wholly within the slave device, and only an _error_ signal is transferred over the bus. E.g. from the 'pdp11 peripherals handbook', 1975 edition (pg. 5-8): "PA and PB are generated by a slave ... [it] negates PA and asserts PB to indicate a parity error ... both negated indicates no parity error. [other combinations] are conditions reserved for future use." The answer is that originally the UNIBUS parity operation was _different_, and that sometime around the introduction of the PDP-11/45, they _changed_ it, which is apparently why Appendix E, about parity in the /45, says what it does! I found the first clue in the MM11-F Core Memory Manual (DEC-11-HMFA-D - which is not online, in fact no MM11-F stuff is online, I'll have to scan it all and send it to Al); I was looking in that to see if the parity version had a CSR or not (to reply to Paul Koning), and on the subject of parity it said this: "The data bits on the bus are called BUS DPB0 and BUS DPB1." And there is nothing else on how the two parity bits are _used_ - the clear implication is that the memory just _stores_ them, and hands them to someone else (the master) over the bus, for actual use. Looking further, I found proof in the "unibus interface manual" - and moreover, the details differ between the first (DEC-11-HIAA-D) and second (DEC-11-HIAB-D) editions (both of which differ from the above)! In the first, Table 2-1 has these entries for PA and PB: "Parity Available - PA ... Indicates paritied data" and "Parity Bit - PB ... Transmits parity bit"; at the bottom of page 2-4 we find "PA indicates that the data being transferred is to use parity, and PB transmits the parity bit. Neither line is used by the KA11 processor." (Which explains why, when, after reading about parity in the MM11-F manual, I went looking for parity stuff in the KA11 which would use it, I couldn't find it!) In the second, Table 2-1 has these entries for PA and PB: "Parity Bit Low - PA ... Transmits parity bit, low byte" and "Parity Bit High - PB ... Transmits parity bit, high byte"; at the top of page 2-5 we find wholly different text >from the above, including "These lines are used by the MP11 Parity Option in conjunction with parity memories such as the MM11-FP." I looked online for more about the MP11, but could find nothing. I wonder if any were made? This later version seems to agree with that Appendix E. I tried to find an early -11/45 system manual, to see if it originally shipped with MM11-F's, but couldn't locate one - does anyone have one? The ones online (e.g. EK-1145-OP-001) are much later. It's also interesting to speculate about _why_ these changes were made; I can think of several! :-) Noel
