Help identifying Mostek machine

by dwightk.elvey＠amd.com

Hi It is always a fun project to write your own BIOS and get CPM running on these kinds of machines. I have brought up CPM on a couple of machines and find it isn't too hard. In some cases, I'll put a Forth interpreter on ROM for that machine. That way I can explore the I/O's for the machine and debug any assembly code before I expect it to work with things like booting a CPM disk.

Oh and an > AIM-65 User's Guide. Are you sure about the Soroc having an 1802? Which model of Soroc? I thought Sorocs used z80s. The one sitting next to me here (an IQ-135) definitely has a z80. It does have a 1602 UART though... Speaking of which, how many Sorocs are still out there? Were they as common in the rest of the world as they seemed in my corner of it? I hardly ever hear of them anymore, even on e-bay. Bill.

Fwd: old hardware help requested

Info needed on Sun SCSI/Ethernet sbus card plus sun sparc2 FS

by jmd5＠earthlink.net

i recently came across 2 X1054A SCSI/Ethenet Sbus cards. I am having trouble finding info about the Ethernet connector. This is not a standard port configuration. Its quite small (measuring 1/2 wide by 1/4 inch tall) and its *D* in shape. Female. are there adapters? adapter cables? I have 2 of these and only need one at present. If anyone is interested in the other card its free. Just pay shipping. If I cannot use this, then both are free for shipping. i also have a sun sparcstation 2 with 425M hd (w/sled), some memory sticks (one stick is bad for sure) with a dual sbus video card (cg6?), floppy drive. the NVRAM is bad. i think i have a sun keyboard too. ss2 for $5 and keyboard is $10. plus shipping. this is *as is* no guarantees. located in glendale california jeff duncan

I got a HP9000 - now what?

by kd7bcy＠teleport.com

I picked up this huge HP box with half the case(plastics anyway) missing... I picked it up because it had a DomainRing card and other Apollo-like ports. I finally figured out it's an HP9000, but I'm not sure which one yet. The board is labeled A1421-66538. It has a 25MHz 68040 CPU. The HP-IL keyboard port is a neat touch. Does this thing use a normal VGA monitor? Looks like this one has a tape drive(DC600 tapes like my Apollos?), and two hard drives - one is a freaking big 5.25" FH like my Apollos, the other is HP SureStorageDisk 1000S+ 3.5" drive. I see 4 ISA slots, one has a DomainRing card. Will the other Apollo cards work there too? Any pointers to good HP9000 info(I'm still recovering from hauling this huge box in to do much searching right now - this thing is bigger and heavier than the Apollos! LOL, I though nothing could get bigger...) I think my iMac is intimidated by this huge box towering over it on the desk now... -- /------------------------------------\ | http://jrollins.tripod.com/ | | KD7BCY kd7bcy(a)teleport.com | \------------------------------------/

IBM 5285

by aeg＠paradise.net.nz

Hi All Another recent addition to my growing collection is, as the title suggests, an IBM 5285. It has a 12" display and dual 8" floppy drives. The separate keyboard is connected at the front of the machine by a large 25 pin connector. Originally passed to me as "working" the machine fired up to display what looked like a single ASCII code at the top centre of the screen and a column of blocks on the far right. The keyboard is laid out very much like a terminal keyboard and testing the keys the keyboard buffer quickly becomes full. This results in what looks like a series of memory addresses along the bottom of the screen. All the while the two 8" drives are merrily spinning away. I have one disk with the machine which when inserted in either drive fails to read or alter the state of the display. My initial thoughts were faulty connections. I took the covers off to reveal about a kilo of dust liberally spread around the inside. I cleaned each component carefully and replaced the boards. Now I don't get anything on the display and the drives still whirr around oblivious of disk or no disk... So... my questions are: 1. Has anyone come across this model before and is it a dumb terminal? 2. What checks would you suggest to solve the disk access problems? 3. Can anyone point me towards a repository of information about it? Thanks in advance Alan
