Osborne 1 - The Last HOPE 2008by billdeg Total messages in this thread: 1 I took an Osborne 1b ROM rev 1.4 to the 2600 magazine "The Last HOPE" convention on July 19th, as part of a vintage computer demo. I originally planned to exhibit an "original" version of the Osborne 1 (with the tan chassis, also model rev v. 1.4), but that one had a bad A drive. "Insert Disk in drive A and press RETURN" is as far as I could get. 
Prior to the event I did attempt to replace the drive. First I had to see what was going on inside of the machine. It takes about 10 minutes to completely disassemble an Osborne 1, if you have a longish phillips-head screwdriver. There are only three types of screws and clearly this machine was made for field repairs.
Anyway.. once I got the system completely apart so that I could get to the disk drives I learned that the drive get">... [ read more ]

The Revolutionary Osborne 1by billdeg Total messages in this thread: 2 Updated: [ More photos ] 07/20/2008 Osborne published a magazine dedicated to owners of it's new Osborne 1 portable computer. The premier issue of June/July 1982 contained on its cover 9 well-armed Afghani soldiers and one "IT guy", apparently manning their new Osborne portable. What better computer for the mobile freedom fighter than the Osborne 1 - rugged, dependable, and sturdy. Just like the Mujadeen solders that used it. 
"..Journalist David Kline recently covered the Afghanistan conflict for The Chicago Sun-Times using his Osborne 1. The July issue of Kilobaud Microcomputing contains the full story of how Kline managed to file his stories faster using his Osborne 1 and modem. Kline will be reporting on his travel experiences with the Osborne in future issues of The Portable Companion... [ read more ]

Another IBM 5150 rev "A"by billdeg Total messages in this thread: 1 I received another IBM Personal Computer model 5150 16K/64K motherboard with the black power supply. The system came with a Plus Hardcard 20, an extra 64K card (combined with the motherboard RAM = 128K system), dual IBM 36 drives with stock controller, and the IBM monochrome monitor card. Initial boot: 9010 201 + (...I then pressed F2 to clear the error, followed by...) PARITY CHECK 2 error I removed the Plus Hardcard 20 and rebooted. This time I only got the PARITY CHECK 2 error message. I checked the jumper settings and re-seated the RAM. System booted perfectly, both drives work. The serial number is 0239462 and the ROM is dated 10/27/82, one year newer than the MARCH IBM PC 5150 previously restored and discussed in this blog. I then tried the PLus Hardcard 20 again. I am not sure if I need the driver or special boot disk, but I get a 1701 error">... [ read more ] |

Updated: [ SW3 #1 to control hard drive ] 08/10/2008
Cobbled together a system from spare parts, but it's 100% AT&T stock for the 6300. I had trouble with the display for a while, but it revived itself. The system came to me with generic DOS 4.01. Decision time If my goal is to return the system to its original state which OS should I install given the following....? [a] The manual states that DOS 3.1 was shipped with the system. [b] The original AT&T 3.1 boot disk is missing. I only have the 2nd (supplemental/operating) diskette. [c] What I do have: AT&T 3.3 or MS DOS 3.1 DECISION I decided to go with AT&T 3.3, because manufacturer trumps version IMHO ________________________ Two more interesting things.
