Secret Weapons Of Commodore Updateby billdeg Total messages in this thread: 1 POSTED ORIGINALLY ON cbm-hackers mailing list by Cameron Kaiser * Floodgap Systems * www.floodgap.com ------------------------------------- ------------------------------------- It's late. It's really late. But it's done, and the 13th edition of the Secret Weapons of Commodore is released. The Secret Weapons of Commodore is devoted to rare, unusual or just plain interesting Commodore peripherals, computers and prototypes, with historical and technical information on their development, specifications and fates.

Commodore 2022 (3022) Printer Testingby billdeg Total messages in this thread: 1 While in the CBM IEEE mood I took out a status-unknown CBM 2022 tractor feed printer I had tucked away in the corner. My son was messing around with the form feed button while I was setting it up. Long story short, we discovered that if you hold down the form feed button and power the printer on at the same time, the printer will print diagnostic test characters (continuously). By analyzing the printout, I learned that the 2022 is at least mechanically OK in that the paper feeds and the printer prints characters correctly. There was even a little bit of ink left in the ribbon. This is a nice feature because it saves a person the trouble of having to plug the printer into a system. I bet this works for other older IEEE printers esp. the 2023 and the Europen 3022. If you're buying a CBM printer on Ebay, ask the seller to perform this simple test for you. Office supply store">...

Prototype PET 2001 photoby billdeg Total messages in this thread: 3 Updated: [ Jan 1977 PET photo ] 08/13/2008 While doing some reasearch on my exhbit, I came upon a copy of Byte October 1977, and on page 54 there is an article about the National Computer Conference in Dallas, TX June 13-16. On that page is a picture of a prototype PET 2001. http://www.vint...e/2001-8/magazine/ I posted two scans, one blown up so you can read the face plate. ...this is to my knowledge the first known photo from a magazine of a CBM PET 2001, and a prototype to boot. BUT this is not the first known photo (Seach this site for "gametronics") - Note that the mag pic PET plate reads: "PET Computer 2001" on the front right (as seen in the blown-up of the two scans). SO - If the Dallas convention marks the first public appearance of the PET 2001. This event coincides with the VCF E ( http://vintage.org ) - 30 years ago to the day, minus one week. Bill">...

TRS 80 Model 1 Early Magazine Referencesby billdeg Total messages in this thread: 2 Updated: [ which is first appliance computer? ] 08/13/2008 Currently working on my VCF East 3.0 exhibit, the 30th Anniversay of the TRS 80 Model 1. I scanned some research materials for possible use. These are the earliest references that I could find to the TRS 80 Model 1. Link Regarding the so-called low-cost "appliance computers" unveiled in 1977: the Apple II (Jan) came well before the PET (June)or the TRS 80 Model 1 (Aug). The TRS 80 was first publicly displayed in August of 1977 at Computermania (Boston) and I believe also PC-77 (Atlantic City), both on the same date.">... [ read more ] |
