The Winnebego Handheld Programmable Code Scanner circa. 1998. Click image for larger view.
The Winnebego Handheld scanners were among the many other peripherals advertised in the back pages of mid-90's Byte and PC magazines. I was reading the Sept 1995 Byte and I noticed a competitor's ad did not have an Internet address1. Turns out that very few Byte advertisers encourage their customers to "check out our web site" in September 1995, business had not yet adopted web pages. I left Zeneca and started my web design company on October 9th 1995. It seemed at the time like there was a huge market for this thing called the web, a once-in-a-lifetime opportunity fo...

MicroVAX 3100 with Storage Expansion
Pictured here is a 1988 (?) Digital MicroVAX 3100 with Storage Expansion boxes. The model number of the 3100 is DV-31BT4-A-A01 which I believe makes it a 3100 model 30. The storage expansion boxes are basically external SCSI hard drives. Their model numbers are DV-31BT4-A-A01(middle) and SZ123-XA (bottom). Click image for larger view.

Photo of an interesting interface for a card punch from late 60's early 1970's. These devices were sold by a company called RealTronics. Click image for more photos.
Cover removed. Note the large two-character Nixie tube display. Click image for more photos.
This control unit appears to be a current loop device, similar to a teletype. The RealTronics system consisted of a PDP 8i with third party hardware. I assume "Real" pertains to RealEstate, but I could only guess. ... [ read more ]

The UNIVAC 1532 is probably from 1965-66 and was part of a UNIVAC 1219 (II) system. The 1532 has a Teletype model 35 on top, with a hood a control panel, and below a tape punch and reader unit below in a drawer. The whole thing is quite rugged. The 1532 configuration would have been installed on a US Naval ship where space was at a premium and rough seas were inevitable. Note the 1 inch 8-bit tape in the back of the drawer.
