R: Opening up PSU for Olivetti M24

by supervinx＠libero.it

Can't check it now... have you looked under the feet on the bottom? Olivetti used to hide screws right there..

Motorola's Punched-Card Reader

by COURYHOUSE＠aol.com

Ed at SMECC FOUND: In the Motorola annual report from 1967 CONTROL SYSTEMS DIVISION The division completed the best year in its six-year history. Orders increased 40% over the previous year. Additionally, two significant objectives were reached. The first was a move to achieve international stature in the process controls field. Early in the year, a sales and service organization was established in Puerto Rico to serve the mushrooming petro-chemical industry in that area. Also, early in 1968, the division established a fully owned subsidiary in England. The subsidiary, known as Motorola Control Systems, Ltd., will service the process control and information processing markets in the United Kingdom and the European Common Market. Second, through product innovation and sales penetration, the division took a giant step in achieving its primary goal ? placing Motorola firmly in the field of information processing. At the Fall joint computer conference in California, the division unveiled its MDR-1000 Document Reader, the first of a family of low-cost input terminals for information processing systems. The MDR-1000 provides a simple means for entering data into an electronic processing system directly from marked or punched cards and documents. This offers systems designers a new, low-cost method of getting raw data directly from the source, without need for skilled data processing equipment operators. The initial application of this "industry-first" is in processing daily operating information for one of the Bell Telephone systems. The immediate success of the MDR-1000 resulted in an expansion of this customer's program. Potential applications for the MDR-1000 in business, education, industry and government are virtually endless. The division's continuing success in marketing its three major product lines ? supervisory control systems, data systems and process controls systems ? increases its technical skills and disciplines in the related field of information processing. The primary skill involved is computer technology. In the area of process control instrumentation, for instance, the division received several petroleum refinery contracts to supply complete networks of field instruments, plus all related computer interface equipment. Three of these major contracts called for tying in with computers >from three different computer manufacturers. Supervisory control system sales also gained impetus during the year. A large system was designed and installed for the Minnesota Power & Light Co., and other systems are under construction for the Getty Oil Co. and Marathon Pipeline Co. The sale of additional equipment for systems installed in previous years continued to increase during the year. This segment of the total sales picture is significant as engineering development costs were generally charged against the original sale. ok lets find one of these readers! sheet and card.... neat!

DEC PDP-16 books

by dstalk＠execulink.com

Hi, I was considering scanning "PDP-16 Computer Designer's Handbook" (1971, DEC) and "Designing Computers and Digital Systems" by Bell, Grason, and Newell (Digital Press, 1972) and have a couple of questions: 1. Are there already existing scans? 2. What is their copyright status? Don

Connecting a Cambridge Z88 to the Internet

by lproven＠gmail.com

I've been asked about doing this for an exhibition. >From some cursory Googling, it seems that the Z88 has a terminal emulator, and equipped with a suitable serial cable, you could just run a cable to a host device with an Internet connection and have a text-only terminal session fairly readily. Not much more than that, though. Has anyone on CC done this? -- Liam Proven ? Profile: http://lproven.livejournal.com/profile Email: lproven at cix.co.uk ?

Motorola's Punched-Card Reader

by silent700＠gmail.com

I don't know their history as regards computing before the 1980s but Motorola seems to have had a brief flirtation with data processing in the form of their MDR-1000 mark-sense and punched-card reader, a brochure for which I scanned tonight: http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/Motorola The original had been damaged by mildew and staining, which I tried to clean up a bit without sacrificing the graphics on the covers, but the inside fared much better.

Opening up PSU for Olivetti M24

by robert.jarratt＠ntlworld.com

I have just acquired an Olivetti M24. I want to inspect the PSU and I have removed it from the machine. But I am struggling to remove the only seemingly removable panel. This is the one with the mains socket and the on/off switch on it. It looks as if it might be hinged at the bottom, but it won't pivot out or come away. Does anyone know how to get inside this PSU? Thanks Rob

Reproduction 8/e panel from Rod Smallwood

by michael.99.thompson＠gmail.com

I received my reproduction 8/e panel from Rod Smallwood (aka "panelman") this week. It looks spectacular compared to the peeling paint on the original. Rod did not drill the hole for the rotary switch because the position varies a little depending on the revision of the switch panel. I put the original panel on top of the new one, marked the rotary switch location, drilled a pilot hole and successively larger holes. I had to adjust the position of the AC power switch a little to optimize the clearance around the switches, but that was easy. The original panel had rubber bumpers between the panel and the front of the chassis that I will attach to the new panel with double sided adhesive tape. The original panel had a tapered relief at the back of the hole for the AC power switch, but the new one does not. I will use a file or Dremel tool to remove some of the panel material. Without the relief the panel will get stressed near the AC switch. Overall, the workmanship on the panel is spectacular. Now I need to repaint the 8/e front panel frame, RX01, RK05, and TU56 so they look as nice as the new front panel. -- Michael Thompson

FS: Fulcrum IMSAI 8080 clone system

by sellam＠vintagetech.com

I'm selling this interesting off-shoot of IMSAI history. It's a Fulcrum Data Systems IMSAI 8080 clone in turnkey configuration. Fulcrum was started by Bruce Wright of WW Component Supply, who competed with Tom Fischer to buy remaining inventory at the IMSAI bankruptcy sale in the early 1980s. Fulcrum was eventually sued and had to cease and desist but not before a few of these systems were sold. Photos and more information are located here: http://vintagetech.com/sales/S-100/Fulcrum/ It powers up but I haven't tested the logic. The bus power is fused and I don't have the fuse caps right now. I can probably round some up with a little scrounging. Otherwise I tested all the voltages coming off of the power supply and they are good. I'm asking $1,200 for the complete system (CPU + dual drive unit) but I'm willing to entertain offers. Please inquire directly via private e-mail. You might also want to check out the other stuff I have for sale by starting here: http://vintagetech.com/sales/ Thanks! -- Sellam Abraham VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap.
