I'm cleaning out my closet due to financial need. (and lack of time and space). I put 3 computers on the auction yesterday: ? HP 86 Computer, Drives, Modules ? http://www2.ebay.com/aw/itemfast.cgi?item=otr9161 ? Apple IIe Computer, Duo Drive, 64K ? http://www2.ebay.com/aw/itemfast.cgi?item=cjt6509 ? Apple IIC Computer ? http://www2.ebay.com/aw/itemfast.cgi?item=znb774144 Much more to come. I'm seriously cleaning house over the next few weeks.

Recent Finds & RE: laser discs...

by foxnhare＠goldrush.com

Recent finds... Been adding to the Atari collection, last weekend snagged a 410 tape recorder for 99 cents, noticed a bit of rattling and discovered a plastic part had fallen off the rewind key mechanism (it triggers a reed switch, probably to mute the signal when rewinding.) glue or tape should fix it. Now all I have to do is find those games I have... I think I have a Telengard tape that has atari on it, I wonder how it will compare to the 64 version... And I also have an Automated Simulations game somewhere (the science fiction one like apshai?), it could have an Atari version on it as well... I might have a possible candidate for a power supply for the growing Atari collection (from a thrift store with a table full of various PSs, and mention of boxes more in the back, gotta check there more often!), it is a 9V AC 1.6 amp supply... so, how much difference is there between 1.6 and 1.7 amps? The least rated supply (listed in the Atari FAQ) to run on an 800/1200XL is a 1.7 amp, can the 1.6 cause problems? (I have yet to try this as the plug is the too small and I will have to solder on a more suitable one for it to work.) Also got an 810 drive, did a power test tonite, the disk went through a 'seek' of some sort (still one PS and no disks, so it's best I can do for now) Now I have disk drives that match the 1200XL and 800! Speaking of the 1200XL I mentioned earlier the keyboard was not functional, a fellow user on the comp.sys.atari.8bit newsgroup suggested checking the keyboard connector, and by-jimminy, it was loose! (Now who would open a perfectly good computer...well..ok, who wouldn't open a perfectly good computer. *grin*.) Books,tapes,disks are nowhere to be found for the Atari (at thrift shops/book stores/flea markets), so far (since a month or two ago) not a one spotted, and I thought Commodore books were hard to find. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Monochrome monitors are pretty cheap out there, picked up a basic Zenith green screen for someone for $2.95, saw a few more similarly priced. -=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- My best find of the week: one thrift store had a 128D unit sans keboard (a 128D is a Commodore C128 computer with built-in 1571 disk drive, latest ROMs, and 64k video RAM) for $7.00. I figured it would be a great 'parts source' for my flat C128 (which has only 16k VRAM and old ROMs), I assumed the 128D was DOA, only to discover it is functional, the drive seems ok too! (booted a CP/M system disk and Renegade, two disks with 128 boot sectors I knew of). Now I'm gonna have to scrounge/hack up a 128D keyboard.

(I >didn't buy one) I got a couple LDs from thrift shops the first ($20) was the great grandaddy Magnavox 8000, still has major tracking problems but it can't interface to anything anyway. The second ($9.95!) is a Poineer 6010? Anyway, it is an 'industrial grade' LD player (had an Armstrong Flooring disc in it). I have some articles for LD interfacing: one for the VIC-20 in a 1982 COMPUTE! and one I think for RS-232 in a 1983 BYTE; but this LD player already has an RS-232 inteface built-in so that point is moot... I am waiting to bail it out of repairs (very minor ones fortunately). Anyone got a Dragon's Lair LD lying around???

HELP with Apple II+ booting!

by kaikal＠MICROSOFT.com

Still no joy on the Apple II+ boot problem. The machine appears to definitely have 48K RAM; at least the NEC chips have "416" on them. Any way I can tell in BASIC? I have 3 disk controllers and 3 drives. The disk controllers have 2 different ROM versions; one is half copyrighted 1979 and half 1981, while the other is all 1981. The card model is 650-X104. There's another ID number, one is 820-0006-02 and the other card is 820-0006-D. Help!!!!

monitors for use with old computers.

by Pete＠madhippy.demon.co.uk

I'm fairly new to the collecting scene and I'm looking for a monitor I can use with some of my systems. I'm mainly interested in the 8bit home computers, spectrum, c64, atari, dragon, bbc etc I'd like to know if there is a particular type of monitor that can be used on the above machines. I'd like to buy, say one, I can use with all of the above. I know there seems to have been a few different methods used in producing the video signals and, from reading newsgroups, I get the impression that it is sometimes possible to select video outputs/monitor inputs such that, even if the monitor is not directly compatible, a reasonable result can be obtained. Any pointers would be greatly appreciated. -- Pete Robinson pete(a)madhippy.demon.co.uk http://www.madhippy.demon.co.uk - faqs, emulators, links, web utilities.

If you (or anybody else) want, I can copy your message into the Fidonet "APRICOT" support echo. There aren't all that many messages in there at the moment, but I am sure that there are still folk with working Apricot machines, that would be glad to help.

HELP!!! Apple IIe - doesn't work!

by BigLouS＠aol.com

In a message dated 97-05-27 23:56:45 EDT, you write: > Should I take one of the video cards out? Are they supposed to BOTH be in > there? If when you boot the machine it comes up with Apple IIe then you have an enhanced IIE. If it says Apple II then you have an unenhanced IIe. Part of the enhancement upgrade involved replacing roms on the motherboard so perhaps the upgrade was done improperly (unlikely). Pulling cards is the best way to isolate the problem. First pull the videx card. If that doesn't solve the problem then pull the AE card, the mouse card and finally the printer card. If your still having problems then you may want to replace the Zip chip with a stock 65C02 (an enhanced IIe uses a 65C02 rather than a 6502). If you still have problems then you may want to try a different controller card or just throw the thing out the window. :-) Lou

Whilst in a self-induced trance, Charles P. Hobbs happened to blather: >Hey, DOS *is* CP/M as far as I'm concerned (look how long it took to >kick that 8.3 filename habit! :-) It is not easy to calculate how long it took for them to kick the habit, as the habit has not yet been kicked... think of it as still being on the nicotine patch. The long filenames of Win95 are only a *bunch* of 8.3 filename placeholders conveniently disguised to the end user. Wanna waste a whole weekend over nothing? Run MS-DOS 6.22's scandisk/defrag on a Win95 volume and see how long it takes you to straighten that mess out... it's easier to reformat and reinstall.
