I have an Atari 800xl and a couple of 1050 disk drives. I also have two copies of the M.U.L.E. game on disk. Unfortunately, I can't get either to boot on the 800xl. I suspect that these are older games that were written for the 400/800 and may need the "translator disk" that allowed the 800xl to run games written for the older machines. Does anyone know where I could obtain a copy of this translator disk? Thanks! David Betz

Stag PPZ EPROM programmer

by coredump＠gifford.co.uk

I have a fine old Stag PPZ modular EPROM programmer: http://www.gifford.co.uk/~coredump/inst.htm#PPZ It takes plug-in EPROM (model Zm2000) and PAL (Zm2200) modules, called Z-modules by Stag. I've recently acquired a new module, Zm3000, which looks like a more recent EPROM module. The chips in the Zm3000 are date coded in 1993, whereas the Zm2000 is nearer 1988. The PPZ main unit contains a 6809 CPU and a small CRT display. Does anyone know anything about this system? What about other Z-module types? In particular, should the Zm3000 work with the PPZ, because I currently get an error message "Incorrect Mainframe"? Thanks in advance for any clues!

road trip score: AViiON, Microdata 1600

by mcguire＠neurotica.com

Yesterday my girlfriend and I returned from a hastily-scheduled road trip to Maryland; we went to see a friend who is gravely ill. While we were in town, we took the opportunity to visit a few other people. Another friend up there is preparing to move, and he dropped a few things in my lap since I was there with a mostly-empty car. The first was a Data General Aviion AV300 workstation. This is one of the few machines built around the Motorola 88K CPU. It came with its original keyboard, mouse, monitor, and a full set of DG-UX manuals. I don't yet know if it's functional, but according to my friend it was running a few years ago. The second is something I'm REALLY excited about. We went to his garage and he pointed me at two dusty card-cages full of boards, and told me that he picked them up from a college loading dock twenty years ago, and that he had no idea of what they were, but there were core memory boards in them. Oh, and there's this lights-and-switches front panel that goes with them. (!) Upon getting them home and digging around, it appears to be a nearly complete Microdata 1600 CPU. I have the two backplanes with card cages and boards, and the front panel, along with some cables. I lack the power supply, but I can build one of those...with that, I think I have enough to resurrect the basic CPU. Neat stuff! -Dave -- Dave McGuire Port Charlotte, FL

Anyone here have the speech module for an IBM PC Convertible they want to get rid of? I just got one of these laptops & was hoping to score one. David M.

Iomega Bernoulli Box 20+20 (A220H)

by mbbrutman-cctalk＠brutman.com

I rescued one of these ancient Bernoulli boxes today. It uses the large (8") cartridges at 20MB each, and it has two slots for the cartridges. Other than for hearing some of the folklore about the drives, I don't know much about it. I'd like to see it run and be usable, but I need some help. - Is it SCSI? If so, what's the pinout on the back? It has a 37 pin female connector that I'm not familiar with if it is SCSI. - Where is the head mechanism? Is it fairly robust and protected if there are no cartridges inserted? This one has no major dents, but it has not been babied either. I don't want to waste time on it if it's just going to be a heartache. (I have enough of that already.) - Cartridges look like they are on eBay. They are cheap enough for me to experiment with. - Is there anything I should know about these beasts before I attempt powering on and working with it? Thanks, Mike

Anyone off to VCF-UK

Frankly, although I'm sure that most people on here are nice folks, there's only a handful with whom I think I'd have much in common and would spend time and money to hang out with and listen to if there weren't something else that interested me (especially since I don't drink beer or eat pizza). Having read some of these comments and especially the sentiment that unless you're a "celebrity" who cares what you have to contribute, I'm thinking the same as Tony, namely why am I wasting my time here? I've got friends who share my interests and there aren't any ignorant jerks like Evan among them nor do they tell me to fuck off; maybe it really is time to rent a dumpster and just toss in those Cromemcos, Vector Graphics, PETs, AIM65s and the 25-odd boxes of manuals and documentation that are taking up space just in case someone might want or need something one day; with a couple of exceptions they certainly aren't any use to me. Something to think about for sure; I may end up actually thanking Evan one day for finally showing me the light.

Data I/O Unipak 2B ?

by scanning.cc＠gmail.com

I just bought a Data I/O 29B with an Unipak 2B from Epay. Everything seems okay BUT the pinout cartridge ( the little module that plugs in the end of the 2B ) is missing. I suspect that all it has is some kind of simple interlock like two pins tied together to tell the Data I/O the cartridge is there ( probably so you can't run the unit with that HAZARDOUS 20 volts on the open connector. Anybody know how to get around this or fake it ? The unit won't do squat without it.... Have not been able to find a schematic of the 2B or the pinout cartridge. Thanks. Best regards, Steven

Would a bog-standard 4164 be a suitable replacement for a MCM4517 in a Sega SC3000H? (was Re: Introduction - Terry Stewart (tezza))

The pinout is the same as the 4164 except for pin 9 (NC on a MCM4517, A7 on a 4164). Could you use a 4164 instead? (it might require a pull-up or pull-down on pin 9 so it doesn't float). Those are rather abundant and still available from a number of sources. -ethan

the new manx is live

by legalize＠xmission.com

Manx is an online catalog of computer documentation. The new manx is up for beta testing here: <http://manx.classiccmp.org> Paul Williams created manx as a series of perl scripts and a database of online computer manuals. Paul has graciously provided us with a copy of the data from the database from which I reverse engineered a compatible implementation in PHP. Later, Paul provided me with the perl scripts which I used as a referene for finishing off the PHP implementation. The new manx is an open source project hosted at <http://manx.codeplex.com>. Please use the issue tracker on codeplex to report any problems you find with this new manx. You can also browse the existing issues in the tracker to see the planned enhancements. The main planned enhancement to come is supporting users and roles to allow community contributions to the database so that new additions don't have to go through a single person. Thanks to Paul Williams for providing the database dumps and scripts and Jay West for hosting the finished application. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
