Wanted: ROM images from HP 9895, 82901/82902, and other HP-IB disk drives

by spacewar＠gmail.com

If anyone has dumped the ROMs from the HP 9895 (8-inch) or 82901/82902 (5 1/4-inch) HP-IB disk drives, which use the Amigo command set, I'd appreciate copies of the images, ideally along with the HP part numbers of the EPROMs (probably 09895-xxxxx and 82901-xxxxx). For that matter, I'd be interested in ROM images from any of HP's other HP-IB disk drives, floppy, hard disk, or combined. Also ROM images from the 9114A and 9114B HP-IL disk drives. I already have one ROM image each from the 9114A and 9114B, but there were multiple firmware versions. Thanks! Eric

VCFMW

by marc.verdiell＠gmail.com

I wanted to extend my thanks to the organizers of this event, and to Jay in particular who showed me the way around bringing up a cantankerous HP 1000 E system in real time, and somehow never got tired of my newbee questions. And the Chinon FR-506 5.25" drive that I picked up there for a very reasonable price, unlike the one I had bothered you about in a previous thread, actually works! All in all a very worthwhile way to spend award mileage on a trip from California to Chicago...

KV-S3065CW scanners

by aek＠bitsavers.org

http://www.ebay.com/itm/201392632552 this is a good deal if the paper path isn't scratched up in them. the CW model has a 11" width feed and can scan a sheet 6 feet long. these are the ones I've been using for 5+ years just don't need any more right now

TK70 sticky unload button?

by kylevowen＠gmail.com

Has anyone else come across this? My TK70 wouldn't eject, and having not had one before, I didn't know just how tactile the unload button should be. After further examination and prodding, I determined that the button was pretty much stuck and refused to come out. Taking the front off and exposing the board indicated that the button seems to originally have been rubber, which is now a nice black tarry goo. I think I can replace the button with a standard tactile push button, this time without any rubbery material. Hopefully that's my only issue. http://i.imgur.com/9Fqb0SB.jpg http://i.imgur.com/AxstKpq.jpg http://i.imgur.com/PCFCfwH.jpg Kyle

Programming & L. Carroll

by c.murray.mccullough＠gmail.com

This is off topic, so-to-say, but computer languages can be esoteric: It's the 150 anniversay of L. Carroll's "Alice's Adventures in Wonderland." May I dare say most people, including myself here(I studied languages like BASIC, COBOL & PL/C, know very little about the programming languages that make old & new computers do what we wish looking backwards? Logic, like "Alice's...", can elude us at any time... Happy computing. Murray :)

MEM11 Status Update

by ggs＠shiresoft.com

I'm making good progress on the MEM11 firmware. I spent the last few days re-doing the firmware build environment. Previously, it would build all the files each time. Now there is a proper Makefile (even though it takes about a minute to build everything). I realized that I needed something better than what I had because there are multiple targets (emulator, FPGA eval board and the MEM11 board itself). Right now I'm focused on getting as much debugged on the emulator since it has a reasonable debuging environment. I've also integrated various test programs into the build environment and use various low level code as part of the main firmware for hardware access. This "kills two birds with one stone" since it tests not only the various hardware functions it also allows me to debug some of the firmware separately from the full code base. At this point, the emulator fully supports all of the J1 instructions (and they all work too!). In terms of I/O (that will be part of the MEM11 board) it supports LEDs and various configuration inputs, FRAM, UART and timers. The biggest risk that I'm taking is that the UART is emulated as being directly exposed. On the MEM11 hardware, the UART will be connected through a SPI interface which requires that all accesses to the UART are asynchronous transactions. The biggest piece of work remaining on the emulator will be emulating the Unibus interface. The work here will mainly to create a means to script various Unibus transactions. However, before doing that, I'll be testing out the boot loader code and the configuration firmware since none of that is dependent upon the existence of functional Unibus hardware. TTFN - Guy

Multitech MicroProfessor

by binarydinosaurs＠gmail.com

Folks, Possibly a long shot since I think the MPF was only a UK/Europe thing but I'll quite happily be proved wrong. I've had a chap asking for a scan of one of my manuals that would necessitate partial destruction. Anyone got the IOM-MPF manual? It's a 6k RAM expansion board for the MicroProfessor MPF-1P seen on my site here: http://binarydinosaurs.co.uk/museum/multitech/iom-mpf.php (Ironically today I'm working in a building that has a proper book scanner, but all the staff that operated it were 'let go' earlier this year) Cheers -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest home computer collection? www.binarydinosaurs.co.uk

Data General Projects

by jwest＠classiccmp.org

It's time to start on the Data General stuff I've had forever but not yet restored :) This time much of it has finally made its way into the workshop so perhaps there will be some progress. Pictures of the initial set of racks to work on are at https://www.flickr.com/photos/131070638 at N02 , but there's more DG racks with devices that can be used at both houses. Trying to decide where to start really, and what pieces to use and what to trade off (I'm not really familiar with DG stuff, yet). At the least, I know I don't want/need the large FPS (Floating Point Systems model 100R) box. Anyone have interest in that part? If folks have docs that might help but are private, I'd appreciate a little access or pointers. My initial questions revolve around what boards from the Nova 4, S/130, and S/200 can be interchanged if desired, I'm still trying to decide which cpu to keep and which peripherals. Time to read what docs I have and scrounge up ones that I don't! I know I got keys with these systems, but don't see them anywhere. The 6021/6023 tape drive uses vacuum columns, that will be fun. The TP1 is an awfully cool retro printing terminal. The 5821NT terminal has (by a large margin) the worst screen rot I've ever seen. The 6125 tape drive is in an odd "desktop" stand like I haven't seen before. Let the fun commence. J
