Hey Joe, How sure are you about IQ-120's having 1802's? ISTR doing a class project on that, studied the schematics (wish I had those now!), and concluded that the design was very much like a microcoded CPU - some PAL or PGA controlling register transfers, with a state register acting as a kind of micro-program counter... Now I wonder if that was some other terminal. It was 20 years ago, and my memory aint what it used to be. I may be interested in that IQ-130; I'll e-mail you off-list. My IQ-135 is actually in pieces (courtesy of UPS ten years ago). But there's a happy ending: I've found somebody with an ailing IQ-135 that needs parts. I'm packing it up for shipping now. Bill.

"The Mark-8 was an Intel 8008" was Re: I thought the Univac was expensive

by Innfogra＠aol.com

It is an interesting batch of sales. If you look at their other listings there is an Intel iPSC, a MASPAR and what I think is an IBM 5100 listed with the a strange title "The Mark-8 was an Intel 8008" listed in "antiques." http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&category=12&item=2542757186 I, too, am inclined that the seller has a problem with decimals. I think they are very unfamiliar with eBay, having just registered. The ads are in the wrong categories. The descriptions are not what would sell a piece of equipment. Also seller in Japan, listed on the Australian eBay site with shipping in misquoted US Dollars. I suspect a Newbie or possibly fraudulent (low probability but worth being very careful) Does anyone recognize the pictures as being from somewhere else on the WEB. Many Japanese are collectors so it could be an original collection. The high valuations lead me to think it might be a collector. If you search their completed sales they are all collectable baseball cards. http://cgi6.ebay.com.au/ws/eBayISAPI.dll?MfcISAPICommand=ViewListedItems& userid=extremejordanfanno1&include=0&since=30&sort=2&rows=100 They brought good money too. The Ford Typewriter is also getting good bids at a price that indicate the decimal places are not misplaced. I suspect a Japanese collector that is a newbie to eBay, and needs to raise money.

Fwd: RE: 8250 LP Double disk drive for the commodore 64

by semlj001＠hotmail.com

Chandra, The 8250 does hook up to a Commodore PET but the stats seem quite different between the 8050 and 8250. I can't seem to find a pic on the net of an 8250 but the drives are side by side.

Fwd: Monrobots

by dbetz＠xlisper.mv.com

Here is the latest message I've received about the Monrobot XI computers. While I'm glad that they are going to a collector, I'm sorry to hear that none will be available for anyone else. I just hope that this collector will make them available in some sort of museum or open collection. I'd love to have a chance to see one in person again. Also, I'm trying to contact Fred to determine if his offer to duplicate the documentation is still open.

Bogen CHS-100A

by cb＠mythtech.net

>I could use a schematic for a Bogen CHS-100A. If you have it could you email >it to me? Was there a HUGE delay in some people receiving posts? Or did part of the archives only recently get picked up by google or something similar? This is the 2nd request recently for manuals that I offered to the list some MONTHS ago. Fortunatly, I am very very very slow at actually taking my recycling pile out, so the manuals are still in my office, just burried at the bottom of the pile. -chris <http://www.mythtech.net>

by dl7ef＠t-online.de

I just owned a 5160 XT IBM. I got the described Xebec Controller. I got the problem, that error 1701 while booting appears. Now I want to do a low level format. But all Debug Addresses like C800:5 or C800:6 or CE00:5 don´t let the format utility of eprom start. What have i done wrong ? What kind of software could I use and where can I get it ? And what´s the correct address ?? I ´ve got a Seagate ST412. Could you be so nice to send me the softwareutility or / and the correct address of the internal bios lowlevel format utility ??? Thanx in advance You´re my last hope. Alex

by nbreeden2＠comcast.net

Hi all, Does anyone have docs for the E&L MMD-2 I could get a copy of. There is nothing useful on the web, the archives here also didn't yield anything useful except for someone else looking for MMD-1 docs. Thanks, -Neil
