HP memory available (HP9000)

by jwest＠classiccmp.org

Maybe not quite vintage... but I have these, and no need for them, and would rather trade or give them away than toss them. I have four memory modules labled as follows: Series 800/900 Memory 32mb A2511-69001 The extractor handle on each module (and the label) says 32mb. But being somewhat familiar (although rusty) with HP part numbers and modules of this type, it is possible that even though it says 32mb on each module that each one is really 16mb, as modules were always sold in pairs for these particular systems. Knowing the origin of this memory, it mostly likey came from a G machine, or possibly a K machine. I cant be sure, but I suspect they are working fine. If anyone wants them let me know quickly...

Best keyboards you've used ever!

by msokolov＠ivan.Harhan.ORG

Mark Wickens <m.wickens(a)rhodium-consulting.com> wrote: > List the best keyboards you have ever used. Right now the keyboard I insist on using is LK201, but that's only because I'm a nut about DEC VTxxx terminals and don't want to use a keyboard whose set of function keys does not directly correspond to the set of VTxxx transmitted escape sequences. I like LK201 better than LK401 because I have no use for the latter's "Alt function" keys, because I don't like how they shrunk from 4 to 2 LEDs, and because LK201 is more sturdy while LK401 is more flimsy. The really interesting keyboard I've used (for Western readers) is the Soviet KOI keyboard. Unfortunately I never got to use the "real deal" (Soviet serial terminals), but I've used the KOI kbd on the BK0010, the Soviet home computer based on the 1801VM1 microprocessor, a Soviet PDP-11 clone, a single chip microprocessor roughly equivalent to an LSI-11. It was a home computer for which you were expected to write all software yourself from the ground up, by entering octal codes at octal addresses (assuming you wanted something other than BASIC or FOCAL that they had in ROM). I really miss that mentality (I still believe every hacker needs to write his own operating system as a rite of passage). Soviet KOI keyboards are really interesting. They are based on KOI, which is the Soviet reinterpretation of ASCII. In Latin mode KOI is identical to ASCII, but thought of differently, in that all characters from 100 octal up are considered Latin letters, so in the mind of a Soviet hacker, '@' is the 0th letter of the Latin alphabet, '[' is the next Latin letter after Z, and the last Latin letter is '_'. In Russian mode characters from 100 octal up are given alternative graphic renditions (Russian letters, not surprisingly). Note that it's the *graphic rendition* of the character that changes, not the character itself; the coded form is the primal form: a compiler will recognise a keyword equally well regardless of whether the tty displays it with the Latin rendition or the Russian rendition. The KOI keyboard was designed around this mentality, i.e., the upper/lower case switch acted on all keys that we considered letters. '{' is the lowercase '['. The layout was different. When we got the first PeeCees I at first couldn't stand their kbd because of the top row layout: how ridiculous it is that '^' (a letter) is on top of '6' (a digit). That drove me nuts. The KOI keyboards were much more rational in that the key layout directly corresponded to the ASCII/KOI chart. The top row keys were in their ASCII/KOI order. The encoding logic was a breeze since with this layout all modifier keys (Ctrl, Shift, upper/lower case switch and the RUS/LAT switch) only had to twiddle bits. MS

Favorite keyboard I've never had the privilege to use: I have a picture on my wall. PS-2 connector, goes to a small keyboard unit. Unit says "Microsoft" on upper left corner and "intel inside" on upper right. The only three keys on it bear the legends: <Ctrl> <Alt> <Delete> :-) Worst keyboard is anything with the little eraserhead pointing device in the middle. Distracts from typing, useless for pointing. -- - Mark 210-522-6025, page 888-733-0967

6809 Forth (was: Sharp PC124x/5x/6x)

by dave04a＠dunfield.com

>You would get the 2 versions that I already have :-). I'd like to see the >6809 fig forth (I assume it existed, and used the 2 hardware stack >pointers, etc). It's not fig, but if you are interested, you can take a look a my tiny little FORTH implementation for the 6809 - Docs are a bit sparse, sorry - it was done on a weekend in response to a collegue who had been boasting that he had created a version of FORTH for the 09 that was faster than any other - I truly enjoyed the look on his face the next monday morning when his test program ran significantly faster on mine... Of course I cheated - my FORTH compiled to directly executable code, which eliminated the interpreter and chaining through threaded links - this has a bit of overhead (3 byte JSR instruction instead of 2-byte link address), however it is offset by the fact that I reduced the header to just the word name (no difference between word types - everything is "native"), which saved me 16 bytes (IIRC) over the wordsize in his dictionary. Yes, it uses both hardware stacks. If you are interested in playing with it, it's available on my museum web site, in the section on my D6809 homebuilt. The source code is included, and if you want to try it out, you can run the D6809 emulator, mount the included disk IMAGE, boot up my CUBIX OS and type FORTH - this will launch a ready to run version of my itty bitty FORTH (about a 2.5k executable as I recall).

Go figure! I suspect they had as much input in the design of that as I did :) Cheers w

HP LA Inverse Assemblers for classic microprocessors

by RupertKirkham＠compuserve.com

Dear Jim, I followed this thread and tried the "FTP" addresses that were given regarding downloading the Inverse Assembler Development Package. Sadly without success as the directory structure has been changed. Therefore is there any chance of obtaining the software from another source. Funnily enough I have the reference manual as this is downloads from a couple of web sites. I am currently building a 68008 based system and I would like to have an inverse assembler for the HP1650A that I will be hooking up to it. Regards, Rupert.

When there were still phone operators calling my relatives in New Mexico occasionally was a problem because the phone operators think it's an international call. However my patents live in Waverly which is near Dover, Lexington, Napoleon, and Wellington. Most of these towns are less than several hundred. I'm sure in the 1800's we borrowed the names from some foreign country. Mike
