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.

Building a CP/M for Lobo MAX 80by billdeg Total messages in this thread: 2 Updated: [ lobo cp/m disk images on the 'Net ] 05/06/2012 I wanted to see if I could do more than boot my MAX 80 using LDOS 5.1.3.  A Lobo Max 80 with a Lobo twin 8" drive, TRS 80 5Meg hard drive, and a set of Percom double density drives all attached to the back of the computer. The system is booting off the Percom drives using LDOS 5.1.3. Click image for larger image.
 Close up of the drives.
Unfortunately my copy of CP/M for the MAX 80 won't boot on a single sided 8" Lobo drive. I need a 77 track DD drive, like a Shugart 850.
I have no idea whether the TRS 80 5 mb hard drive actually works, but it made for a good picture.">... [ read more ]
