There is now a new version of the HPCC schemaitcs CD-ROM. This one contains schematics for around 140 classic computer devices, I'll put a full list at the end of this message. As with the older disks, the schemaitcs are hand-drawn (by me). You will ahce to put up with my writing :-). There;s very little apart from the schematics, there are no isntruction o ntaking the things apart, no theory-of-operation information, and so on. In some cases the HP service manual is avaialble on-line, and will contain some of that information. All profits go to HPCC (Handheld and Portable Computer Cluh). To order the disk (I believe it's now 2 CD-ROMs or 1 DVD-ROM), please contact Dave Colver, sectretary at hpcc.org, who can tell you the price, etc And now for the machines chargers/eramco_pp Portable

OT: Televisions

by brianlanning＠gmail.com

Well, maybe not so off topic... I have two things I'd like to ask about. First, I'll be replacing the display for my main computer shortly. I'd like to get something larger than 20". I'm thinking an LCD wide format thingy. I'm considering getting a "flat" television instead of a monitor. Most of them have DVI or VGA connectors on them. But they also include component inputs, HDMI, and maybe some other things that can ease connection to classic computers. A composite RCA is a must. Can anyone suggest a TV model that that's relatively fast (like < 8ms), and has a high enough resolution that would also be good for the classic stuff? I'm thinking 1080p would be fine for a windows desktop. The next question pertains to console televisions. I'd like to find (much to my wife's dismay) a console television like the one my parents had back in the late 70s. I'd like to use it to play old video game consoles from the 70s and 80s. I believe these were all vacuum tube sets though, is that correct? Is there a good source for these things (the TVs and the tubes) today? I imagine people threw them away mostly. If these are difficult to find and/or maintain, I've considered trying to create a replica console television from a newer set, maybe even something with an LCD in it. I'd probably prefer an original though. Then i could invite my mother over and sit too close to the television for her. brian

XXDP program to test a DLV11-J

by jhfinedp3k＠compsys.to

Does anyone know if an XXDP program exists to test a DLV11-J? Any do you also know the name of the program? Thank you in advance if you can help. Jerome Fine

Adding VGA, PS/2 keyboard, and microSD to generic Z80 CPU classic computers

by lynchaj＠yahoo.com

> platforms. > > The idea is impressive, but that PCB is huge. Any chance the design could be made smaller? Jim Hi Jim I was thinking more about your question. The system in the photos is using a standard PropIO board with a *prototype* CPU adapter "shim socket" which would *not* be part of the final design. If the tests prove out then the perfboard and ribbon cable would be replaced with a 2"x1.5" shim socket PCB that would plug in under the host Z80 CPU. It would export the Z80 pins out to 40 pin dual row header. The PropIO would connect to the shim socket PCB via a 40 conductor ribbon cable. So yes, in that sense the system would be smaller than what is pictured in the N8VEM post. It would be functionally identical. I hope that clarifies things. Thanks and have a nice day! Andrew Lynch

Adding VGA, PS/2 keyboard, and microSD to generic Z80 CPU classic computers

by lynchaj＠yahoo.com

> platforms. > > The idea is impressive, but that PCB is huge. Any chance the design could be made smaller? Jim Hi Jim The PropIO was designed as an ECB standard board (160x100mm) Eurocard format and is intended for use with the rest of the N8VEM system. However, the subject came up of adding SD to KayPro on the vintage-computer.com forums and rather than designing a board unique to that system my hope is to reuse an existing part with little or no modification. If you were to design a specific Propeller board for the KayPro it could be much smaller but then it would be forever tied to that platform. The concept here is to make an adapter board to allow general purpose N8VEM boards to provide IO to the less common vintage computers that are "stranded" due to lack of current hardware development and/or small developer community. WaveMate Bullet is an example but I am sure there are dozens if not hundreds of others. I am trying to gauge what sort of interest there is in this approach if any. Certainly this is less than optimal solution for any specific machine but then it may be applicable across a whole spectrum of vintage computers (Z80 DIP 40 socket). Most likely this idea will go no where but it is interesting to me and the initial test results are showing promise. This in theory could be a way to add features like DiskIO (IDE/FDC), video (VDU), or microSD (PropIO) to less common systems that otherwise would never get it. Thanks and have a nice day! Andrew Lynch PS, the empty sockets on the PropIO are for the second Propeller. It is currently unallocated but communicates with the SBC over the ECB in a similar fashion as the first Propeller which serves the PS/2 keyboard, VGA, and microSD interface. The second Propeller has several free IO pins which are intended for builder experimentation. There are a few proposed ideas on how to use the second Propeller such as an EN28J60 Ethernet interface with PropNIC and/or the Propeller USB converter. I was planning initially on adding TV, audio, and some other toy doodads but the other builders convinced me to keep the second Propeller unallocated and instead add the mini prototyping area. The PropIO also includes a mezzanine connector and mounting hardware for a full sized mezzanine "upper deck" so builders can add whatever suits them. PropIO is a rather experimental board and not really a final design - more of a proof of concept. Thus it is ideal for situations where non-typical adaptations like jamming into a KayPro are being explored.

Adding VGA, PS/2 keyboard, and microSD to generic Z80 CPU classic computers

by lynchaj＠yahoo.com

Hi! I am working with one of the N8VEM builders to make an interface to allow a generic Z80 CPU computer (DIP 40 socket) to interface to the N8VEM PropIO board. The benefit of this would be that any Z80 computer with a DIP 40 socket could add VGA, PS/2 keyboard, and microSD capability. I think this would be helpful for debugging and also transferring data from legacy platforms. http://groups.google.com/group/n8vem/msg/b287ef9fbe0f1e8d Since the board plugs directly into the Z80 CPU socket it is independent of any particular bus. Any new installation would require custom software for the platform. It appears the KayPro can access the PropIO using MBASIC so writing software should be practical. In theory, this approach may be applicable to any of the N8VEM ECB peripheral boards (Disk IO, VDU, prototyping board, etc). The concept may be applicable to other CPUs with the appropriate shim socket PCBs. I believe this could be particularly helpful for classic computers that lack an active development community. If anyone is interested in doing some experimentation with your vintage Z80 computer please contact me. Thanks and have a nice day! Andrew Lynch

Wirewrap boards update

by steerex＠ccvn.com

Yo! I have posted a few pictures of the wirewrap boards that are offered. I haven't used this free service before so, I hope the links work OK for everyone. http://tinypic.com/r/2q0iovn/6 http://tinypic.com/r/whhb7o/6 http://tinypic.com/r/2cp97j5/6 http://tinypic.com/r/kaqkjl/6 http://tinypic.com/r/2ed1esm/6 http://tinypic.com/r/2chw679/6 My brain is getting kinda soft so, I mistakenly said the pins were on a .4" X .1" grid. That is not correct. They are on a .3" X .1" grid. So all the common DIP packages will plug right in. Sorry for any confusion. SteveRob steerex [at] ccvn [dot] com
