The bezel is not mine, so no trade here. Just hang-on and wait. I tried almost all possible settings on the EPSON, it does SEEK the track, but can't find the sector. So when the motor goes on and it seeks, I assume the jumper is set correctly? What are the functions of the 2x 50k and 5-25p variables connected to the WD2797 for? My XF551 has a CNINON FZ-502 drive, perhaps a European batch? I needed to install the EPROM on my PCB and jump the CPU to 8040 Since the masked rom burned into the 8050 is not functional..... The boot sequence is also rather interesting. Seems to be a part of the install routine of the PDD. During the blue wait-screen, the motor turns for ever. When you insert a non formatted disk, it just waits, keeps spinning. Only when you insert a valid format it continues and tries to boot. Bit0 of $247 is set. My FREEZER_2005 plugged to the back: It does not fire-up when you press the button. :-( And the EDITOR in debug needs the math-pack, so I can't hack into the PBI-rom..... Time for altirra. Later! Sijmen.

Ah, OK. miss-communication. I did not get the remark, you never can support it. After you included the CONT support, both seemed to work. But I must have been mistakenly using the wrong emulation-settings. Hotel does load and plays, but when you buy stuff to setup your hotel, the rooms stay at zero. So no income, not playable. Yeah, German is a language we learn here at school, neighbor country.... Anyhow, it does not matter, I use ATARI Basic instead. Nice work BTW on ATBasic, it is also on my MyIDE-][ cartridge for usage too. Keep up the good work.

I'm afraid the ATBASIC has lost it touch with both "HOTEL" (game starts, but values are zerod) and "a day at the races" (system crashes). Booted with a plain Altirra with Xl/XE OS rev2

Not much progress today :-( It takes more time then expected to get things sorted. And not enough hours in a day. 74LS10 on U8 with pin10 up, I'm sure now this is making device V: non functional. PDD attached or not, powered up or not, 1450-OS or 1400-OS. Device V: is off and stays off, schematics show that this pin is the strobe to the SC01 hardware. So it must be in the socket for the voice to work. The only difference I found in the OS is that it does not say "1450" (as the 1400 does) when you type DOS to go into selftest. Even a 800XL-OS or MyBIOS boots the system with PDD/Voice/Modem functional. H1/H2 are the passive components mounted on a socket. The other passive parts are: 2x 50k BOURNS 3299 type W variable resistor. 1x 5-25 pF variable capacitor. One capacitor mounted on the back, serial to the variable capacitor. Need to check the value later. Here are the pictures of the drive that came with the 1450XLD. It has 1 jumper, set to S0 when I got it. Also a picture of the XF551-jumpers, it has two jumpers. (set to Mx and S0) The EPSON works fine with the XF551-enclosure, but refuses to read (it does seek) with the PDD. The XF551-drive works fine in both...... Could it be something very simple, like the RPM or Modulation is just out of spec.? Also I found a new screen when you boot the 1450XLD with SELECT down :-) Not sure what the function is, It seems the option to boot without PDD-disk is removed. Bezel is coming later, this one is in bad shape. Partly broken/cracked, one mounting-pin gone and one positioning-pin. It detaches by tilting the top towards you, then release the mounting pins from the inside. First you have to remove the storage-bay from the inside to make this possible. This bay looks familiar to me. Automotive-part from my old Nissan I had in the early 80's....?

Hi Bob, Pictures of the drive-mounting are attached. I formatted a disk in the EPSON (XF551-enclosure) and that works. With DOS2.5 and then wrote DOS to it. No errors, disk is bootable. Then I booted this disk in the PDD-XF551-mechanics, works too. Hot-unplug/plug to the SD-521 and tried to DIR or load DOS. Still with the disk formatted in the SD-521. The heads move from track-0 to the middle about 14 times then stops. Errors -144 I see 2 jumper packs on the drive. One with 5 jumpers (Mx and DS0-DS3) to select drive, 1 jumper is on DS0. Second is near the LED, 2 positions, position 1 has a jumper. I'm a total noob when it comes to jumpers on 360k-drives, viva las vegas is my style here. But please advise. How do you change the SKEW? MyDOS boots but can't format, SD or DD nothing happens, Enhanced it tries to format but errors with -138. After that, the disk is clean/formatted, but nothing written to sectors 1-3 and DIR. I tried to configure to 40 tracks/1or2side/1step/SDorDD, no success H1: 4k7 on 1 and 7 150 on 3,4,5 and 8 H2: 1k on 1 1N914 on 3 (-|<-) 0.22u on 5 Grtz, Sijmen. [edit] forgot to mention, loading DOS 2.5: XF551 6 seconds. PDD also 6 seconds.

74LS32, You need the resistor-values on H1/H2 I guess too :-) I make a list later this weekend. The PDD now seems stable. I changed the IO-cable from MB-to-PDD and use the XF551-mechanics. Current testing: I can boot from PDD with my XF551-mechanics, very stable. When I toggle bit0-$247: SIO D1-D4 are access-able again. (This does not work when I first booted from SIO, you need to boot from PDD first). When I switch the mechanics to EPSON, type DOS: The drive spins and continuously seeks for the correct sector and never finds it. (hot-) Swapping back to the other drive and that one works. Hmmmm. So I can need a bit of help here on the EPSON SD-521 Strangest is , when I put the EPSON in my XF551-enclosure, the drive runs just fine. RWTEST on the PDD: 411 B/s write and 1170 B/s read, that is a bit disappointing. But is seems when I boot and load DOS, that takes less time then from my 1050. Lets measure that later. Are you planning to rebuild the PDD-board? [edit] Just tested the XF551 with Epson-drive: 383 B/s write & 1081 B/s read.

I tried my luck with the latest atari800 (3.1.0?) It has 1450 emulation included. But I got nowhere, yet. Its very difficult to switch from one emulator you use everyday to a second.... I did ask Avery too (p.m.) to include 1400/1450 emulation. That won't happen at the moment unfortunately. I'm currently running a 1400XL and 1450XLD and the Voice is awesome! Modem is of no use, the PDD is relative fast. Later! MOV07613.MPG

I have a bare PCB too, but not having plans to build it from scratch. Was a Christmas present and/or trade with Curt many many years ago :-) Perhaps we can rebuild the PDD in future too. Later!

Does somebody have SALT-software to check either the 1450/1400 or the parallel drives? Other diagnostic-software is welcome too!

There seems to be a problem with the 34p cable from MB to PDD. When I fold it, it works, relax it doesn't. Standard floppy-cable, I must have some at my attic. But still running my XF551-mechanic not the EPSON-drive. I found that I can toggle the PDD on/off to access SIO D1-D4 by toggling bit0 of $247 I make some pictures later today/weekend, Bob. To accomplish: nothing, just having fun for a friend who owns the system. He has a 1090 too that needs testing And the trill of having a 1450XLD at home....for now....always wanted one. I saw one when I was 16 or 17 on a electronics show back in the 80's Large ATARI stand, StarRaiders running in the middle..... Called Firato in Amsterdam (Netherlands) Also a list of materials and some good photo's of the wire-wrap for you all. The wires are color-coded for DATA, ADDRESS, POWER, LOGIC. Later! Sijmen.

I had to flip the PCB for this. Yes, 10.000 Mhz. Now the drive is lost again, no IO anymore. Screen stays if I want to boot a disk. Extremely flaky or there is a bad contact somewhere.... I tried to format a disk when it did work, but no success. Loading DOS or a game did work. You insert a disk, close the door and it boots. Register $247 showed $83, so the PDD uses PBI-device #1 But not anymore. Back to square 1...... How to get to square 2?

Hell yeah! I connected my XF551-mechanics and it boots now. Wondering what is wrong with the original EPSON SD-521..... Stupid ON/Off-switch..... Now, next is to run RWTEST.....

Short update, The ON/Off switch on the PDD-board powers the 87p50 That is flaky/defective..... So back to square one. Power-on: - drive spins short. -screen -drive spins constantly When i press RETURN it tries to boot from SIO, drive stops after some time. I'm so close......

Hi Bob, (To others, yes I have re-seated the 87p50 micro-controller with piggy-bag 2732) I have the impression there is a problem with the 87p50 micro-controller. Perhaps it dead on my yesterday afternoon..... The drive had 3 ways of noticeable bootup before this point. All during the screen that waits for a disk. 1/ drive spins short, then longer and stops. 2/ drive spins periodical short continuously. 3/ drive spins continuously. To me #1 looks like the most correct way of starting-up. So I powered down and re-seated this 87p50. Now when I boot-up it does #3 above, always. The 87p50 stays cold. Yes, register $247, I found that %1000000 is V: and %0000010 is T: What is the bit for PDD? So I can try some commands using my freezer_2005. Something else: on the 1450MB chip U8 (74LS10) had pin 10 bend-up. Resulting in V: being not installed, I removed it and installed a fresh 74LS10. This installs both V: and T: drivers at $E48F Not sure if this bend-up pin is needed to start the PDD-board? I change it during the day, so both versions do not start the PDD, only the V: Do you have an 1450xld? Both select-lines (pin 12,14) stay low. Pin 16, motorB is the the one that turns off the motor (yesterday), not pin10 motorA. Now pin 16 stays low, motor on constantly. Pin 8 is pulsing (index) Other tips how to check? I have a scoop to check signals to/from 87p50 Are the schematics anywhere for this proto-board? Let me know, Sijmen.

The system is not mine, unfortunately.... It is borrowed from 2 brothers who have bought it during their tour through silicon valley back in the 90's. Price is unknown to me. I attached some more info. Rom's, picture of the casing and the wire-wrap (......) 1450-PDD.zip

I did a lot of stuff yesterday and this morning, but still no result. ProWizzard: I can boot standard SIO to MyDOS or any other software. When I switch off D1: and try to send DIR (status) D1-D8, I get error -160. When I enter a D: in the handler table with PBI-entry, nothing happens. I see in PARDEV that devices %10000000 and %00000010 are installed, I assume V: and T: bob1200xl: I just disassembled a XF551 and used that mechanism, same result (no boot over PDD). Then I put the EPSON SD-521 in the XF551 enclosure. That boots over SIO just fine, so the EPSON-drive is okay. This leaves me to interrogate the PDD-interface....... When I disconnect the PDD, the system just boots normally as if it is a 1400XL. No bootscreen, just normal. I noticed the VOICE when you enter selftest has a lower pitch then on the 1400 and it does not say the model number "1450" as it does on the "1400" There are some handwritten notes, I attach them. And some pics of the PDD. The buscontroller had fallen out of it's socket, so it's in a separate picture. Perhaps somebody recognizes the handwriting or signature? The mainboard has a BLUE sticker with 00 on it. I dumped all ROMs, checked them here and at Curt, they are okay. I have equipment around for testing, but no knowledge of this wire-wrap board. Suggestions? Grtz, Sijmen.

Hi Guys, Perhaps somebody knows. I am testing a 1450 XLD at the moment. System is not TONG, but the 1450-board with PDD-daughterboard. It was bought from B&C computers back in the 90's. I get to this screen, inserting a disk does nothing. RETURN will boot from SIO, T: and V: drivers are installed. I tested the drive-IO and it seems to work, index is pulsing, the PDD controls MOTOR_B and it spins on command. But inserting a disk does not clear "disk-change ready on pin34" Anyhow, help? Grtz, Sijmen.

Okay guys, final version. Attached: V1.2 or here: www.mr-atari.com/birdfood Instant fun for 1-4 players! Included are these files: ROM, ATR, CAS, MP3 and XEX. The XEX loads at $1000. MP3 to record your own cassette! Tested on 400/800 and XL/XE with 16k minimum. Perhaps there are volunteers for artwork? ....this is not my thing...... I like SenorRossie suggestion very much :-) (Cartridge-label, Cassette-inlay, Disk-label, t-shirt...) Enjoy the game! Grtz, Sijmen. BIRDFOOD V1.2.ZIP

:-) Thanks guys! I am working on the request, but I also found a little bug in multi-player. You can not go all in a hole without coming out ever. So I fixed that first. Also the extra game features work to get you further. On request of my nephew, the bird will move back always when you eat food. I have a bootdisk that runs on a 600xl un-expanded Atari, but not happy with the result. Writing an OS is easier that a bootable-game..... I want to release .CAS .ATR .XEX and .ROM later this month. Perhaps some (suggested) artwork. Later! Sijmen.

Ok, I will do that next year..... I tried XEX-loader in Altirra and MyIDE-][ fat32loader. Both work, so I did not check further. Hmmm, I want to keep it below $4000 to make it work on all Atari's too. Happy new year!

First v.1.1 beta, but I guess it is ready. 4 player version (needs 4 paddles) is a party-game! free download from my site: www.mr-atari.com/birdfood Or here at AtariAge. :-)

MyBIOS is on hold for now, still working on the BIRDFOOD-game v1.1 :-) I tested with 4.9.B8, but I'm already on B9 myself, but not burned into my 800XL yet. No idea yet why it does not download. The 850 was a challenge too (timing of COMMAND is very critical), but that still boots. I have dumped before Modemlink starts, so during the prrrrrrrrrrrrrrrrrrr of the OS sending the $4F over SIO. Hmmmm, or is the bootcode already jumped to? The manual says something about not using a cassette, so perhaps it using some kind of handshaking on MOTORGO to identify if the 1030 is still there? Let me know, otherwise I write a program to download the code and not start it. But that will be next year. Busy with the family.

Hi :-) With the 2005-Freezer, this was a piece of cake, afterall. I did not open the 1030 to look inside. I can confirm the PSU is 9V AC (NOT DC!) using 3.5mm jack. The 1030 boots like the 850 does (see APE-log below). It only answers to STATUS after some time and then a READ sector. I dumped the boot-sector to disk. $400-$47F It loads into $600. D:R1030B.OBJ It uses a lonely RTS (MyBIOS does not boot the device, so work at hand....) and then does a SIO-call, $58,$01,$3B,$40,$00,$0C,$06,$00,$00,$28 So download software to $C00, length $2800 I dumped memory content $C00-$33FF to disk. D:R1030.OBJ Added device is T: LOMEM is set to $3200, so what about the lost $200 bytes? Well, it seems to hold the names of the programmers as egg DOSVEC is set to $C00 I wanted to extract the OBJ-files with Altirra latest BETA, but I can't find the H:device anymore...? Success with the files and spread this disk around. Grtz and a happy 2015 in advance to all ! Sijmen.

Ok, I need some time, seems I do not have the correct PSU for it. 3.5mm jack, 9v AC...... Typical Atari, each device it's own power-issue. I'll send a PM when ready.

I have a 1030, just let me know how I can help.
