More on the Commdore D9090 hard drive with pics: http://www.vintag...ives/D9090_sn3674/ I have given up trying to find a 6-head Tandon 603s, and I decided to use a 4-head ST-225 because they are easier to find. I used a B-128 to format the drive. 1) On the controller (top) I snipped J14 jumper to make the D9090 think it was a D9060. This modification is necessary because the D9090 controller is set to use a 6-head drive. Clipping J14 converts the controller into a de-facto D9060 which expects a 4 head drive. The D9060 came with Tandon 602s. 2) I removed the Tandon 603s hard drive that originally came with the drive, reassembled w/o cover. 3) ran a quick test to be sure that the drive was put back together safely: > ?ds$ [enter] 73, CBM DOS 3.0.0 etc 4) I used the following command: >header "degnan",d0,i01 [enter] Are you sure?">...

Epson Equity 1

Just picked one of these up locally. Starts to read Epson DOS 2.11 boot disk, it posts "Equity Loading..." for about a 1/2 second and then poops out with "Non system disk or disk error.." Any other working DOS results in "Boot Failure" and the computer locks up. The dip switch settings appear correct. I tried flip-flopping the disk drives and connections to the motherboard. No luck. The drive connectors are not your standard IBM PC drive connectors so I can't try any other drives. I have used a high % iso alcohol to clean the heads. Disk controller embedded in motherboard. I don't really feel like taking the whole computer apart to get to the motherboard. Do you think it's worth trying to fix? I feel like I am restoring an 86 Corolla, not worth it...Comments?">...

I have finished my testing of the Aeoromp Double Density Controller and Tandy DDC for comparison purposes. I did not test a Percom DDC, but I can if you need me to. Test Units: 1) Three Expansion Interfaces (E/I's), one is a 26-1140 and two are 26-1142-1's. 26-1142-1 s/n 014121 26-1142-1 s/n 005581 26-1140 s/n 047396 they all work at least to the point to attempting to access the diskdrive for the OS. 2) Two Percom DD disk drives - wired together as drive 0 and 1. These were the test drives, but also tried Micropolis 1053 II dual floppy and a regular old Tandy mini floppy drive. 3) TRS 80 Model I with Level II Basic 26-1003, s/n 008498 works, extensively tested, my "test unit" for all testing. TEST RESULTS 1) 26-1142-1 s/n 014121 with Aerocomp DDC and Percom DD disk drives I was able to load DoubleDOS 4.23 and DOSPlus double density ver 3.4 48K using Percom driv">... [ read more ]

Commodore B Series Tips and Tricks B 128 and CBM 256-80 By Bill Degnan 1. Get as many CBUG disks as you can, as well copies of the resources listed at the bottom of this document. You will also need to track down a copy of SuperScript II so that you can read B Series word processing files. SuperScript II, the B Series Commodore User's Guide, and the Programmer's Reference can be purchased from Freeware utilities, IEEE drive manuals, and B series commercial software can also be purchased from this source. 2. You will need a PET to IEEE cable to connect peripherals (such as disk drives) to the B series. 3. To activate most commercial software; attach everything and with the program diskette in drive 0 hit the SHIFT+RUN/STOP keys. 4. Most software written for the B Series computers is ONLY compati">...

Updated: [ Exatron Stringy Floppy ] 05/23/2005
Here is a preview of a more in-depth report on the Exatron Stringy Floppy Pictures The stingy floppy was introduced in April 1979 at the Computer Faire in San Francisco USA. The order form for the purchase of a stringy floppy includes a field to select the drive software for either the TRS 80, SWTP or S-100. I have a typed copy of the s-100 assembler, but it's for the Cromeco. The "nose" protrudes 1/2 inch from the drive. The dimensions of the hole from which the nose protrudes is 3" wide x 1" tall The Stringy Floppy Wafers are 2 11/16" x 1 9/16" (must be metric). Most of the documentation refers to the TRS 80 with Level II BASIC, except for the Cromeco assembler. Bill D">... [ read more ]

5-18-2005 I have an IBM 4956 Series I System as described below (circa 1976-83). I have limited experience with this era IBM and will gladly except assistance in the mean time I will slowly work to restore its function. I was told that it was operational when taken off line 20 years ago and appears to have been stored adequately. Assembled the system is housed in two 6-foot rack cabinets with a total weight of 600-800lbs If you want it you will have to come to the Landenberg, PA USA which is on the extreme south-eastern tip of the state, about 10 miles from I-95 where Maryland meets Delaware. Bring a truck. I can provide pictures or additional details upon request.
