I saw a Radio Shack printer- typical black and silver/gray color scheme- at the WARAC swap today. Didn't get a close look at it due to sharp elbows in the vicinity. I think the guy was asking $20 for it. What I could see, looked like it was almost new condition. *WARAC: West Allis Radio Amateur's Club.

emulating an Apple II+ in an FPGA

by brianlanning＠gmail.com

I noticed that there's an article in the december circuit cellar that talks about emulating an Apple II+ in an FPGA. It was an interesting article, although I only understood about 20% of it. As a software guy though, the hardware "code" has me interested. Maybe this would be an easier and less time-consuming way for me to learn about hardware. brian

Looking for Altair 680 monitor ROM image (or other simple 6800 software)

by derschjo＠mail.msu.edu

Decided to dust off an old software project -- at one point I was working on a Tektronix 4051 emulator, a machine based on the Motorola 6800 CPU. I've coded up a simple 6800 emulation & disassembler but I'm lacking some simple 6800 code to test out its accuracy on "real" code. I'd like to put it through its paces on a simple piece of hardware before tackling the (mostly) undocumented quirks of the 4051. (It's much easier to debug a hardware emulation when you're confident the CPU emulation isn't the culprit...) I thought the Altair 680 would be a good starting point but I can't for the life of me find any dumps of the monitor/VTL ROMs on the 'net. Anyone have any leads for these or other 680 software? Thanks, Josh

Cleaning up: Apple II stuff (and some TRS-80 docs) to give away

I think there was a very late (meaning mid-80's) Far-East clone that looked similar to the VTech Laser 128 but also had a Z80 in it. Funny, isn't it? Franklin clones the II, VTech clones the Franklin, and then somebody clones the VTech :-) Tim.

Cleaning up: Apple II stuff (and some TRS-80 docs) to give away

by joachim.thiemann＠gmail.com

Ok, I've been sitting on this stuff for a while now, it was supposed to go to someone in upstate New York, but I haven't heard from him for a while. I need to get rid of it to make room, so if someone wants to take it, it's free to go. This stuff is in Montreal. Pictures in http://www.tsp.ece.mcgill.ca/~jthiem/classiccmp/ First is a German Apple IIe, came with a family that immigrated to Canada in the 80's. Has a serial card, a Microsoft Softcard (CP/M and possibly 80-col), a printing buffer and floppy. Comes with 2 drives, bunch of original Apple floppies, documentation (including two books for the softcard) etc. Also I have an unlabeled II, probably a plus, likely a clone, built >from kit it seems. All chips are labeled and socketed (see picture) - great care was taken to assemble this. With floppy card and two drives. Also troubleshooting documentation, and some original manuals for Ultima, Zork, and other games. Also comes with a green mono monitor - that also has documentation which includes schematics. The game connector is brought to the back to a DB-9, and there is a homebrew joystick for it (made from an R/C stick and two pushbutton switches in a hobby box). Finally there is an unknown board, obviously a Apple II clone, but has both a 6502 and Z80 on it. Strangely, no ROMs (except for char rom?) but I have a unpopulated ROM card that may belong to it. Some corrosion on the underside, it probably doesn't work anymore. Still all chips are socketed, would be a good place to pull from. (The other two are assumed to work, but haven't been switched on for many years.) I'd like to give all of this away as one big pile. There are also boxes of floppies and other miscellany. Too large to ship, but can fit into a car trunk easily. Unrelated - but also free to good home - some old TRS-80 docs: Series I Editor/Assembler, Level II Basic ref, Tiny Pascal User's manual, "Getting started with TRS-80 Basic", "TRS-80 Graphics", VTOS 3.0 Operator's guide, and a "cheat sheet" for Scripsit. Could conceivably be shipped. -- Joachim Thiemann :: http://www.tsp.ece.mcgill.ca/~jthiem

Working Telebit Netblazer available

by classiccmp＠crash.com

Buddy of mine in Western Massachusetts has a working Telebit Netblazer with (he believes) a complete set of manuals. He'd like to find it a new home rather than recycle it, free for cost of shipping from ZIP code 01012. He gave no guidance regarding international shipping, but /might/ be open to it. Contact me if interested, and I will provide your contact info to him on a first come, first served basis. Thanks, --Steve.

Chrislin Industries Q-bus memory module

by labomb_s＠yahoo.com

Hi folks, I'm in the process of resurrecting a Heathkit H-11 (essentially a DEC LSI-11) that I acquired a few years back. It came with a memory card that, after much creative research, I've determined is a Chrislin Industries CI-1103 module. It's a 32kw board with no parity, and it uses 4116 16kx1 dynamic RAM chips. It has two 8-position DIP switches for configuration. Would anyone happen to have any details relative to configuring this board? Thx... Scott

SGI Part/System

by whsiung＠simconsultants.com

Hello, I came across your post online asking to trade a SGI Iris system and I wonder if you might have another SGI system called Onyx 10000 laying around for trade or sale? Or if you have any boards removed from this system, please let me know. Thank you & I look forward to hearing from you. Best Regards, Winnie Hsiung CentraTech Corporation
