Genuine KM11 board (and plea for RX01 Front Bezel)

by rickb＠bensene.com

Tony D. wrote: > Are any DEC enthusiasts here jealous of this : >https://www.flickr.com/photos/tony_duell/33427116663/in/dateposted-public/ Interesting coincidence. I was digging through some boxes of stuff yesterday, and I came across two sets of these in really nice condition. Haven't tested 'em yet (had /no/ idea that they could be used for diagnosis of an RX01 control board) but looks like they should be pretty simple to check out. I had didn't know of the existence of these before yesterday. I did a little searching and found that they are useful for debugging 11/35 and 11/40 systems, as well as RK05 drives...but didn't see anything about the RX01 drive electronics. Speaking of RX01's, does anyone out there have a spare front bezel for the RX01 that they'd be willing to part with? I have a working RX01 on my 8/e system (both drives good, amazingly) but the bezel was missing when I got it. It'd be nice to have, as it looks rather dumpy in the rack with the rest of the system.

Genuine KM11 board

> From: Tony Duell > Are any DEC enthusiasts here jealous of this Actually, not me! I'm an old enough campaigner that I recall when real light bulbs were standard, and they were a total PITA! So when LED's arrived, we all though they were the greatest thing since sliced bread. So I'm now very happy with my LED-equipped KM11 clones - I still have that anti-bulb bias! :-) Noel

Looking for TRS-80 Model parts (and/or someone in the Phoenix, AZ area)

I did a quick check, but have not seen any writeup of the protocol and keyscan matrix. Does such a thing exist? I haven't seen such although I know a few folks with ambitions of such project. I can put you in touch if they're not actively listening to this list and want to chime in.

More likely than not especially give the condition you mention. The TM-848s are not the most hearty of drives.

by COURYHOUSE＠aol.com

very good radioengr give Jim a hand with it It is going to take a pretty big box to ship it for Jim.. I am trying to remember how big the think is I have not seen ours in eons. We have some large boxes we have saved but will have to see what it would take to get at them. The one thing I would recommend is some sort of internal support against crushing.. almost an inner reinforcing frame that would prevent collapse of the box and thus shattering the plastic. Used to run into stuff like this when shipping hp 2624 terminals etc. Then the other way is one huge ass box and that injectable foam stuff in 2 molded sections... with some wood stakes that keep top from crushing.

Just picked up a TRS-80 Model 12, and it boot to the "insert disk prompt" ... Yay! But, no card cage, and no KB (and no disks, but those might be easier to find) Found a seller of a model 12 with these items, but local pickup only. I'd like to get this unit up to the Model 16 specs, with Xenix on it. I see the cards are available, but without the cage, no joy. Jim -- Jim Brain brain at jbrain.com www.jbrain.com

SWTPC Tape files

by unclefalter＠yahoo.ca

Hi there, I was wondering if anyone knew of a repository that had SWTPC tape files archived (as .WAV, .TAP, etc). The 6800 system I am presently using is wired according to original SWTPC specs and does not have a DB25.. so I cannot simply switch cables from CT1024 to PC terminal like I could with my other unit. I'd really like to make use of the AC30 also for a more authentic experience and was hoping someone had wavs archived somewhere so I could play them into the AC30 with my phone or something and then record to actual tape. For the last couple of evenings I have been manually entering in the data for TSC BASIC from a txt file Bill Degnan was kind enough to post.. just doing as much as I can stand to and then saving progress to tape. Eventually when it's finished I'll make a wav archive and just use tape to load it. Obviously I wouldn't want to do that for every program though. Anyway, I know someone on vcfed at one point was talking of setting up an archive and even had made copies of Tic Tac Toe and 680 BASIC. Hoping someone out there knows where those and/or more might be found, or if there's another way (say using two MP-C/S cards) to pull in S19 files and then record via AC-30 to tape. Thanks muchly! B

Well ... they are packed away at present.. I do know there are several systems and a printer. Do not remember if there was software with them or not. stashed many years ago... I always had wished it was a model II and I suppose was holding this it in reserve in case a 2 does not show. In a message dated 4/23/2017 8:40:37 P.M.

Ed# Yes, the 2, the 12, and the 16 look similar. There are Z80 and 68000 CPU boards. Which of the variant versions of CP/M do you have for it?
