I normally wouldn't post this, but I have no way to save these and would REALLY like to get copies of the control store proms >from them for future use in simulators. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1247&item=5198040316 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1247&item=5198040308 Unfortunately, Crisis scrapped all of their early 3000 boards about a year ago, just before I started looking for the data.

Data I/O 2900 system disk?

by kahrs＠caip.rutgers.edu

I obtained a Data I/O 2900 programmer at Dayton in rather grotty but serviceable shape. But it is missing it's little old floppy (the disk, not the drive). The Data I/O website is silent on this. Anyone know where to find one? Also, to add to Ethan's Dayton report: I saw several Ultra 1s [one going for $5 at the end of Saturday] but no DEC, No SGI and certainly no Xerox Altos.

Apple Classics found at local salvation army...

by john_boffemmyer_iv＠boff-net.dhs.org

Browsing Wappingers Falls, NY, USA salvation army today and walked past an Apple Performa 6115 and an Apple PowerPC 7200/120 with 10/100 Ethernet add-on card! Both work and there is an Apple 14" monitor, keyboard and video cable adapter too. Talked to the manager lady and she said she'd let it all go for $14.99 US. I don't do Apples too much and don't have the money to spend, but if anyone in the area wants em, they are still available. -John Boffemmyer IV

classiccmp knowledgebase

by jwest＠classiccmp.org

Just wanted to say thanks for the people who have contributed knowledgebase articles to the classiccmp knowledgebase (www.classiccmp.org/kb) I do know that one person here is working on a really good article, should show up there soon! So, who wants to spearhead putting in a short knowledgebase article about hooking HP-IB devices, given the recent discussion :> Jay West

PDP-8s and -10s

by aek＠bitsavers.org

>>DEC through the 'golden age' didn't go after that market. They tried to >>target scientific rather than corporate computing. > >One of the oddities is that the 36bit machines the 10s/20s were well >known for their timesharing with huge nubers of users. And they did put effort into front-end terminal concentrators on the later models of those systems. TOPS-10 had a significant influence on the user interfaces of some of DEC's smaller operating systems (RT-11 and RSTS for example), as well as CP/M. Google for discussions on alt.sys.pdp10 for why this wasn't true for RSX and VMS. I suspect that the driving force for tools (esp in TOPS-10) inside DEC came about because much of the software development inside of DEC for other CPU families until they converted to VAXen was done using cross-development tools on their internal timesharing systems (MACY11, etc.) and because 10's were THE machines to have in universities (MIT, CMU, etc, etc) if you wanted something that had a lot of good tools for a moderate amount of money.

Update on HHC Basics

by zmerch＠30below.com

Well, I have good news and I have good news... (and just a little bad news)... I have now erased a bajangle of eproms, I have quite a few Basics burned and lots of spare blank carts, so they'll hit the mail soon. I have tomorrow off, so I'll prolly pack/address/ship then. If not, definitely over the weekend. Tuesday nite was going to be my "Pack'em up nite" but the wifeypoo got a line on a good job, so it was transformed into "Rewrite the Resume nite."[1] Wednesdays are a PITA for me (to work at 7:30am, get out at 8:30 pm or later) so I rarely feel like doing anything after work. Of course, my LCD monitor "went blank" Tuesday nite, so I had to figure out the cause of that last nite... I was a grumpy dude by 11:00 pm. ;-) Turns out the LCD monitor died... :-( I grabbed my wife's monitor and am using that temporarily until I can get a new one in. I did test a basic cart in my HHC, and it seems to work fine, *except* I think my RAM's a bit wonky, as once I create a program, then exit BASIC, it thinks I have 2 bytes of free memory left. Weird. It might also be a limitation as to *which slot* the chip goes into - I didn't diddle with that. Or... I don't believe that the internal batteries are functioning, so it might be a power problem causing the wonkeyness... Anyway, the Basic itself comes up and it takes immediate commands just fine, and I've entered in 2-3 line programs that run fine until you exit basic, then it thinks there's no free memory left. Like I said, weird. Anyway, I'll send out individual emails tomorrow with the status of each order, but I wanted to let everyone know I didn't forget 'em! ;-) Laterz, Roger "Merch" Merchberger [1] After a 10-year hiatus from the workforce, it was quite a job! -- Roger "Merch" Merchberger | Anarchy doesn't scale well. -- Me zmerch at 30below.com. | SysAdmin, Iceberg Computers

Replace roller rubber on HP 9825 tape drive

by vcf＠siconic.com

I'm trying to repair the tape drive in an HP 9825. The roller has melted (no surprise there). It seems like I could just get a bit of silicon tubing or something that has the same diameter and guage as the existing roller. I know this has been discussed before but I can't find any specific messages (by the way, the CC archive search is broken, Jay). Can anyone provide any tips or guidance so I don't have to re-learn mistakes already made? Any tips for cleaning off the existing material? Isopropyl alcohol? Any thoughts of using heatshrink tubing and applying multiple layers until it has the same thickness as the original roller? Thanks for any help. This will be a candidate for adding to the knowledge base once I've successfully replaced the roller. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Talking of the 380Z...

by ard＠p850ug1.demon.co.uk

Since the 380Z seems to be popular at the moment, does anyone have info on 2 bits that are not properly described in the Information File? The first is the dual cassette controller. The pinout of the 7 pin cassette socket is given, as of course is the schematic of the VDU board that contains the cassette circuitry. The controller seems to contain a couple of relays to control the recorders (were these powered from the system 5V line or a separate power supply?) and switching to allow either one recorder to be used, or two with one used for recording the other for playback. It's possible to make some guesses as to how it was wired, but some real details would be nice The second is the SIO-2 board. This was a bit-banged serial port using, IIRC, 3 lines of the user port. 2 ouput lines for TxD and thr reader control relay, one input for RxD. At least knowing what port bits were used would be a help... -tony
