Paul, I picked up Pete's unit, and the case is in good shape. Others have also asked for bits and pieces. But I also got an extra motherboard! I might now have enough to repair the two machines. If I can revive it, I'd like to keep it intact - I hate "killing" machines. If not I'll post here for the parts. Might take me a while as I have many other projects going. I also promised Pete I would repair his tape drive on his other working machine and convert it to QIC format in consideration for letting me have his dead machine. So I have a bit of work ahead of me now...

Many of you may remember that last year (and previous) Heron Point ran out of tables before we ran out of people and stuff to put on them. If anyone has one or more folding tables they don't mind lending to the show (you don't have to use it yourself,) we'd much appreciate you bringing it/them along. Put some masking tape with your name on it underneath to make sure you get the right one(s) back. I'll be bringing one 5' folding "banquet" table myself - this would be the ideal size but whatever you have will help. This will allow us to pack the two rooms most efficiently and expand comfortably out into the hallways. The more people and computers we can welcome to the show the better it will be. Extra network cables, power strips and extension cords will be handy as well. As for reservations, I have heard from a number of you but not all that I usually see there. If you'd like table space, let me know your requirements (in units of 2'x5' tables) and demo theme, if you'd like that listed, ASAP. We're going to be tight this year (and that's a good thing) so please give some thought to what you can fit into 1-2 tables worth of space, if possible. Thanks all and I'll see some of you at the 8/30 meeting. -j ------------------------------ Message: 11 Date: Thu, 07 Aug 2014 21:43:33 -0400 From: Steven Landon <slandon110 at gmail.com> To: cctalk at classiccmp.org Subject: FS:AmigaMini- Thin Client- The Dedicated Amiga Emulation machine Message-ID: <53E42B45.4020509 at gmail.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed I started a project a a while back to come up with a nice way to run Amiga Emulation. Came up with a prototype recently based on an HP t5735 Thin client that has enough power to run the emulation smoothly. Finally got all the bugs worked out and I thought id sell some that I built up. I call it the Amiga Mini Specs are as follows HP T5735 Thin Client 1GB RAM, 1GB ATA Flash Disk, Holds Windows Embedded 16GB flash disk, Holds UAE and all other relevant files 8GB USB Flash Drive that mounts in workbench for easy file transfer. Over 1000 WHDLoad Games come preinstalled on the 16GB flash drive, Along with 500 Demos. AmigaForever is also included. Comes with ClassicWB 3.1 UAE installed and the system boots into Amiga Workbench 3.1, The cool part is it has Picasso emulation, so you get 32bit color at 1280x1024, Looks great. Boots right into Workbench 3.1 as soon as the system powers up. You can also configure UAE by just hitting the F12 button. Here is a youtube of the prototype http://youtu.be/HPRHPqXSgRs The internet is fully functional as well. So you can browse the web with AWeb, Chat on AmIRC with it. Transfer files via FTP or share files via SMB. Im asking $120 shipped anywhere in the USA. Good for peeps who want to see if they like the Amiga Platform, and its cheaper then finding a tricked out expanded amiga. I have 5 available, If there is demand for more I will build more of them. ------------------------------ Message: 12 Date: Thu, 7 Aug 2014 19:48:59 -0600 From: Eric Smith <spacewar at gmail.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Cc: "General Discussion: On-Topic Posts Only" <cctech at classiccmp.org> Subject: Re: looking for end screw mounted card guides Message-ID: <CAFrGgTR6+SwOyoUbiAzGM3Td_ZbBHv73KNjeQFGhUJiKs7X7MA at mail.gmail.com> Content-Type: text/plain; charset=UTF-8 On 8/5/14 5:36 PM, Eric Smith wrote: On 08/05/2014 5:43 PM, Al Kossow wrote: On Wed, Aug 6, 2014 at 12:52 AM, John Robertson <pinball at telus.net> wrote: So was the Pacer.

Hardware-wise, the line included a desktop model, a deskside model, a shared hard-disk unit, several printers, a network option in the megabit range that utilized thick twinax cable and (iirc) a star topology, a serial communications (for a modem) option, and likely other things. Screens were high persistence green phosphor, with at least two intensities for text. I don't remember point addressable graphics. Keyboards were IBM-style buckling spring; as I recall the layout was slightly unique. Floppies were 8", fairly capacious, reasonably quick, quite reliable. Printers were big, fast, dot matrix, top mounted tractor feed. I think at least one model included a multi-pass NLQ mode. Draft mode was IBM-esque, with dotted zeros and an odd diagonal 'S' character. Construction is pure IBM, with reliability and serviceability in spades. I haven't seen electronic stuff online. I have paper docs for a couple of models and some of the options, as well as not-yet-imaged floppies containing diagnostics. I do intend to get them scanned/imaged eventually, I swear. Strong need and urgent pleas for specific things may add motivation. :) No boot disk is required. A fair amount of the available software was actually written in BASIC. At least a few utilities were compiled or assembled binaries, but as far as I recall, even those were not booted The BASIC is an extremely capable business type, with forms, file/disk handling, ISAM type functionality, etc. It was even possible to do serial communications over a modem with it reasonably well, other than some limitations in keyboard handling. I'm not sure if adding the network and remote disk added code on adapter cards to support those things, or if the support was in the base unit firmware. IBM offered the usual AR/AP/GL/Inventory/etc packages. I'm sure there was a word processing tool, though I can't seem to remember anything about it. There was an application generator tool called BRADS (business rapid application development system or thereabouts, I think). The "rapid" part was ironic; while it was certainly faster to build some sorts of simple applications with it than to write them from scratch, BRADS itself was pretty slow. I'm sure IBM had other offerings. I think I also recall seeing a directory of third-party applications, though for the life of me I don't recall anything about what was on offer. I don't believe there was a customer option to write code in anything other than BASIC. The weight of 90 lbs for the desktop unit is not a joke. Besides being built like an IBM product, those 8" floppy drives are stout, and constitute a significant chunk of the mass. I've not dug far enough into my desktop unit to read the markings on the CPU chip, but a few bits like register layout shown in the maintenance documentation match the 8085. I'm pretty sure these systems use a paged memory layout, at least for the firmware. It's the only way they could provide all the functionality that's in there.

It seems that those aren't cheap lately on the eBay. I also have a TRS-80 Model 12 that's been made a bit redundant by my Tandy 6000 project and the TRS-80 Model II that I have on the way. I've overhauled the keyboard with new foam pads, replaced the Rifa caps after one of them got a bit over-excited, fixed a shorted cap on one of the floppy drives, and other such stuff to make it work. It doesn't have the card cage option. Do y'all suppose that my Model 12 might be a fair trade for an original PC/AT system, if anybody was so inclined to make the trade? And if so, might there be anybody around southern California who would be interested in meeting up to make such a swap without the need to pack and ship either of the heavy, fragile beasts? -- Mark J.

This means that for each incoming character the 11/34 has about 90usec or so to process it. More than enough time to read it from the DL11-W, store it in memory, manipulate some counters, etc. The XXDP TU58 driver can handle this, as it is not interrupt driven, it is polled. I haven't tried the RT-11 TU-58 driver at this rate, but it may have issues as I believe it is interrupt driven. It would be an interesting experiment. On the host side I am using my TU58EM program on a PC. It can easily handle the 115.2kb serial data rate. This is a standard 11/34A with MS11-L MOS memory array, no cache option. I have been using this configuration for a few weeks now and have seen no issues at all in loading and running XXDP diagnostics from this emulated TU58 device. My mod is not specifically described, but there is at least one web page out there that describes modding the DL11-W for higher baud rates. That page described the crystal and divider changes, but did not go as far as changing the UART to a newer version capable of 115.2Kb.
