PERQ System F Workstation Computerby billdeg Total messages in this thread: 1 The PERQ System F workstation computer is I believe the first commercial workstation, if you don't include the Xerox Alto.
She's filthy and missing the keyboard but this is quite rare.

Tandy TRS 80 Model 16Bby billdeg Total messages in this thread: 1 Here is a TRS 80 Model 16B, capable of running both Model II / 12's Z80 software and Motorola 68000 XENIX.
Ran a quick test. Lit up the RIFA cap, but I noticed that the system flashed the expected request for a boot disk. Should be restorable. Keyboard status unknown.

Diagnosing Error Codes Franklin ACEby billdeg Total messages in this thread: 3 Updated: [ Franklin ACE RAM - MK4315N ] 07/30/2012 The Franklin ACE 1200 computer was an Apple II clone. This system has the version 2.3 ROMs. Click image for larger view.
This is the persistent error code that appears on the screen when attempting to boot an Apple II diskette in drive 1.
NEXT: Determine what the error codes mean, and repair. I am guessing I have bad RAM, 3715 could be a RAM memory address, the other codes probably represent diagnostic values that explain the error, the pointer or stack value at the time of the error, or something like that. We'll see.
Here is a link to the Apple Monitor program. The Franklin was cloned from the Appl">... [ read more ]

ADDS Regent 20by billdeg Total messages in this thread: 1 This is an ADDS Regent 20 terminal, the only one I have seen with no numeric keypad. This terminal can be set for current loop or RS232 operation. Click on image for larger view.
This guy needs some serious cleaning but it actually powers up and displays a prompt. More to come.

ME1702a EPROM Programmerby billdeg Total messages in this thread: 1 Built by a friend from the kit, I am now the proud owner of a ME1702a ePROM programmer unit. Martin Eberhard did a spectacular job on this device. I insisted on using an original 70's ZIF socket, which needed a squirt of DeoxIT, but other than that it worked perfectly the first time. Now what to program, what to program???? Next I plan to put MINOL on 7 1702a's, see how that goes.">... [ read more ] |
Adventure!by billdeg Total messages in this thread: 3 Updated: [ Log Dump from Adventure Play ] 07/18/2012 This screen shot shows the use of Digital's OS-8 to enter commands. The first command demonstrates how to load BASIC. The second command, "RUN RKB0:ADVENT", loads and runs Adventure! This and the images to follow are photos taken while running on a PDP 8/e computer using a VT 52 display. That's me in the screen reflection.
Opening credits screen of Adventure!
Adventure! is probably the most famous "interactive fiction" program (text adventure game) written for a computer. Adventure was originally written for the PDP 8 computer, I believe the PDP 8e, but I am not 100% sure about that. The whole interactive fiction genre has received a lot">... [ read more ]

Two New S-100 Boardsby monahan_z Total messages in this thread: 1 For those interested in S-100 Bus systems and corresponding CPM software, Andrew Lynch & I (John Monahan) have just finished constructing a second prototype of an S-100 Bus video board capable of SVAG video resolution. For those interesting in a better S-100 video display you might want to take a look at this board. It is capable of displaying a very crisp 100 characters per line display. It is based on the LAVA-10 video chip set. This is a Xilinx Spartan 3 FPGA module. Please see here for more details:- http://s100...VA-10%20Board.htm We have also completed a prototype 80286 S-100 master/slave S-100 CPU board. In my system this runs with a clock speed of 12MHz. It is the next stepping stone from our earlier 8088 and 8086 CPU boards. It works with the 20 or so other S-100 boards we have done and allows one to boot CPM86 or MSDO">... [ read more ] |
Lee Felsenstein Visits MARCH / Workshopby billdeg Total messages in this thread: 1 Pioneering microcomputer advocate and engineer Lee Felsenstein paid us a visit at our most recent MARCH club event June 30 / July 1st 2012. That's me in the middle. Click image for larger view.
Members of the Mid Atlantic Retro Computing Hobbyists club value these hardware restoration workshops because we can share skills and experience. We gather from all points north and south to set up ad-hoc workshop tables with our favorite tools and parts bins. Each of us bring a vintage computer or two and we work to clean and restore the systems to full functionality. We often go to the wee hours, but the time goes by fast.

IBM CP/M-86 1.0by billdeg Total messages in this thread: 9 Updated: [ CP/M 86 Disks ] 06/05/2012 IBM CP/M-86 v. 1.0 boot screen. Click image for larger view.
A working IBM-branded CP/M-86 version 1.0 OS disk has found it's way to me finally. These are not easy to find.
By 1982 it was too late for Digital Research to secure a foothold as the operating system of choice for IBM's new 16-bit PC model 5150, six months after Microsoft's MS-DOS was already available. MS-DOS had more features and it was cheaper.
I am not sure of the actual sales figures for IBM CP/M-86, but it can't be a high number. Original copies of this operating system are very hard to find today.
For more information on the subject, read the July/August 1986 Micro/Systems Journal article titled ... [ read more ]

Apple IIeby billdeg Total messages in this thread: 1 The original Apple ][ e computer.
Not much to say here, this is the original version of the Apple IIe, and this particular unit has a 64K card. I spent some time working through the 7 or so Apple IIe's I have, some need work. I'd like to get this one running with the Microsoft Softcard, so that I can run CP/M.
