In Adrian's photo of the Intel MDS225 here, http://img9.imageshack.us/img9/6826/intel2.jpg you can see a row of eight push buttons with LEDs in them just below the CRT. They are a really nice push button that I have a certain affinity for. Does anyone know who made/makes those or have a modern source for them? Chris -- Chris Elmquist

I've fixed four out of four LCDs - by replacing only the visibly bad caps - in the past few weeks (Samsung, Acer, and DCLCD). One shudders to think of how many fine working screens must get thrown out every day for such a trivial fault.

Lots of Amiga stuff available

by dbetz＠xlisper.com

I recently acquired a bunch of Amiga equipment that I'm not sure I'm ever going to get a chance to use. I'm currently looking for someone who might want this equipment. I got it for free so I will pass it on at no charge as well. Just briefly, the main items are: 1) Two Amiga 500 computers 2) A sidecar style hard drive for one Amiga 500 3) an Amiga CD32 game machine 4) a Paravision SX-1 attachment for the CD32 with lots of additional ports to allow the CD32 to be used as a computer 5) two 1084s monitors 6) numerous floppy drives including a number of 3.5" drive and one 5.25" drive 7) software and manuals for most if not all of the hardware I've seen one Amiga 500 boot from the hard drive into Workbench. I've also seen the CD32+Paravision unit boot into Workbench from a floppy. I don't know the state of the second Amiga 500 but it appears to be in good condition. I'm in southern NH and would like someone to take all of this equipment. Thanks, David Betz

Microcolour terminal

by ard＠p850ug1.demon.co.uk

Has anyone ever come across a 'Microcolour' terminal? It was made in the UK by Microvitec, who were better known for monitors (often BBC micros were used iwth Microvitec Cub monitors). I have a couple of the Microcolour base units here, no monitors or keyboards. Here's what I've discovered so far... On the rear are connectors for 'Host' (DB25 plug), 'Printer 1' (DB25 socket), 'Printer 2' (DB25 socket), Monitor (DB25 plug), Keyboard (DE9 socket), mains in/out (mormal IEC connectors, a couple of fuses and the on/off switch. The only feature on the front is a green power-on LED. Insdie is a PSU (the 2 units I have differ in the PSU design, but that's not vert important at the momnet0 nd a crdcage containg 3 PCBs (with aslot for a 4th). These plug into a backplane at the front fo the machine using 64 pin A+B DIN41612 connectors. The loweremost PCB carries the Host, Printer 1 and Keyboard connectors. On this board are the processor (6809), EPROMs, RAM (some of which is battery-backed -- I have removed the leaking NiCdsm there is no other damage), 4 6551 serial chips (for the printer 1 port, which is RS232 DTE, even though it's on a socket :-(), the keyboard port (TTL level), and the host port (it uses 2 6551s for this so yuo can have split baud rates I guess), a 6821 (used at least for the Printer 2 port which is thus a parallel interface, a cable rund from a SIL header on the PCB to the DB25 socket o nthe chassis), etc. One of the EPROMs has a label 'Regis' which seems to suggest what protocol it may use. The other 2 boards are video-relates. One seems to be text video (6845, several 6116 RAMs in a row on one edge, another couple of 6116s which may well be programmable character generator, there's no EPROM on this board), and lots of TTL. There's a 10 pin header which is linked ot part of the monitor connector. The last PCB seems to be graphics related. It contains 128K of DRAM, some 74S189 SRAMs for a oolour palette and again lots of TTL. There's a 15 pin header that links to the montior conecetor. Now for the monitor connector. It's a DB25 plug. One pin is not fitted, one is wired to chassis ground. 9 of the remainder go to the text PCB (one pin on the header is not used), the remaining 14 go to the graphics board (again one pin on the header is not used). Now fo the odd thing. All those signals are TTL level. The output of the graphics board (12 pins on the header) are the outputs of those palette RAMs. In other words 12 bits digital (I asusme 4 bits each for R,G,B). The otuput fo the text board is similarly a 4 bit value (I think). And of course there are 2 sync signals, which I could identify. Vsync is 50Hz (not too suprising), HSync is 21.8kHz. In other words, EGA rates .Sothis thing used a specail EGA-like monitor with many more input bits. I suspect I am goign to start by hooking up a normal EGA monitor (assuming I can find one, I think I have a 5154 around here) to see if I can get some output, albiet with fewer colours than I should have and then try modifying such a montiro t oincrease the numebr of bits on the DACs. As for the keyhoard, at least it's synchronous serial (of the pins on the DE9, there's TTL level TxD and RxD, ground, +5V, +12V, -12V). I have no idea of the baud rate, etc, but if necesary I cna use a logic analyser to see how it initialises the appropriate 6551. -tony

Floodgap back up

by spectre＠floodgap.com

As shocked to see that I haven't been bounced off the list by now, Floodgap and all of its hosted projects are back in full operation on a new T1 from AT&T/DSL Extreme. Do not ever do business with Time Warner Cable Business Class. They took six weeks to do nothing, culminating in fairly nasty threats to their legal office to get them to release me from the contract. AT&T took almost four weeks, but at least they got the NIU in, and the router got activated today. Reverse DNS is pending. Sorry about the downtime. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- ** COMMODORE 64 BASIC V2 ** 64K RAM SYSTEM 38911 BASIC BYTES FREE ----------

RK05

by cc＠informatik.uni-stuttgart.de

Hi, I'm trying to repair my RK05 drive. It seems that it doesn't find track 0 when loading the heads, thus moving the heads to the inner limit, forcing a return-to-zero and starting all over again. I think the fault is on the M7681 card (cylinder address and difference), the output of E16 pin 8 (CAD3 zero detect H) doesn't change, nor does the input on pin 10. And here comes the problem: the M7681 isn't described in any DEC documentation I've found so far (apart from the schematics), only the older M7702 card (the function is practically the same, but they are completely different designs). The new card contains several undocumented TTL ROMs (8223). The output of pin 6 of E1 goes to the input pin 10 of E16, probably a difference==zero bit. So here comes my question: does anyone have a ROM listing of these ROMs, especially of E1? I'd like to know what exactly that ROM is doing. Christian

intel mds 225

by jzg22＠drexel.edu

... I've never seen one of those mds computers before, but as soon as I saw it I realized that it is what the Speech Plus/Telesensory Prose 2000 Speech Synth card which I have was originally meant for/designed for. The card I have is in a special speech plus 'prose 2020' metal case with its own power supply, and the two 'multibus'? edge connectors of the card are unused, power and serial and audio come from/go to special secondary connectors on the board. But clearly, without the special prose 2020 case, the prose 2000 card would be used in one of those computers with 'multibus'. Any chance you can dump the roms from the computer? Given that there don't appear to be any multibus cards installed, are there even any roms to dump?
