HP Apollo Series 700 model 705

by hansp＠aconit.org

I have been given a couple of these (thanks Paul) and would like to know more about them. These were obviously used as network stations, neither has a hard disk and from the looks of the inside hard disks were never installed. Both power on and blink the indicator lights on the front but I get nothing on the connected multisynch monitor - is this normal? Any pointer to technical info would be welcome, the HP doc archive does not mention this model. Regards, -- hbp

HP gear

by pat＠purdueriots.com

I've just come across an HP 9000/300 and 9000/220 in a dumpster over here at University Salvage. I see that the 300 has a 68010 (first one I've owned), but am not sure about the 220. Both have video and 'keyboard' connections. I've found some 300 info using google, but nothing helpful on the 220. Also, are these worth anything? I've got no drives with them, but I did get a bunch of lab I/O boxes (multimeter, and other things) with them. -- Pat

Conclusion: Commodore 64 *is* lame!

by foo＠siconic.com

Ok, here's how lame the C64 is. I have three of them. I have three different types of video cable. The first thing I notice is that the C64 I've been working on has a different video connector than the other two. The other two are older; the one I've been working on newer (based on serial numbers and internal differences). The one I've been working on is most likely dead. I can't get anything out of it after trying various combinations of cables and monitors. So how come none of you C64 experts piped up to tell me that the video connector on the C64 changed over time? The later one had more pins, and the C64 video cable (that I searched all over for and finally found) only plugs into the newer style connector. It won't plug into the older ones because there are too many pins. Worse, I can't get the video to work if I plug the cable into the back of the 1702. I can only get it to work with the composite connector on the front. Maybe it's because I still don't have the right cable. Whatever. This is a nightmare. See, this is why I have such a poor opinion of the Commodore 64. Sure, technically it's a nice computer. But practically, it's a pile of shit.

Sanyo MBC-555 - help?

by mhscc＠canada.com

I've got one of these cuties (monochrome monitor), but no software or docs. Disk spins on power up, but no text at all on screen; have tried PC-DOS 1.0 through 3.3, but no message of any sort. Is this normal with a non-Sanyo disk, or does it have a problem? Anybody have a boot disk, and if so, can it be tele-disked or would I need the physical diskette?

ANN: New Altair32 Emulator Release

by rcini＠optonline.net

Hello, all: I wanted to drop a quick note to the list to let everyone know that I've just posted a "dot 10" release of the Altair32 Emulator. Normally I wouldn't release a minor revision such as this, but a heavy user of the emulator has found some minor errors in the disk image code that causes corruption of the disk images after repeated use of the image. He also found an error in the binary file handling code that, upon looking at the changes history, has been around since version my first version. So, if anyone has been using version 2.3, please download and begin using version 2.30.10. Thanks.

I hate to do this, but...FA Osborne 1 with orig. software

by nerdware＠laidbak.com

It's time to thin the herd.... I don't have time for the old computers anymore, so I'll be clearing out the rest of my collection over the next couple of weeks. Last time I tried to offer stuff here with "make an offer", I got no responses, so I went the epay route this time. If you're interested, it's an original beige case model. It lights up, but drive access seems to be down. Has original disks in original box, including CP/M, CP/M utilities, MS BASIC, Supercalc, and Wordstar with the keyboard overlay. AC cord cover is intact. Aside >from yellowing, it's in great shape. The auction is at:http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=20479715 73&rd=1 Thanks.

Cromemco 64KZ Info Needed

by mhscc＠canada.com

The 64KZ is organized as two 32K Blocks (not 16); the A15 switches control whether that block is in the lower or upper half of the 64K range. Reset out disables that block after a reset to allow the boot ROM to use that space on power up. Override & DMA are only relevant for DMA operations. Bank switching is done by outputting a byte to 40H (this address is set by a jumper block/PROM): bit 0 = bank 0, etc., and each block's bank(s) are of course set with SW2 & SW3. Good luck; I've got a manual somewhere that I could scan if you haven't already gotten one elsewhere, but probably not this weekend. Email me off-list if I can help. m -----------------Original Message---------------- From: "Mike Davis" <ipscone(a)msdsite.com> To: cctalk(a)classiccmp.org Date: Wed, 21 Aug 2002 21:48:17 -0700 Subject: Cromemco 64KZ Info Needed Reply-To: cctalk(a)classiccmp.org Hope this is not a duplicate. The first one did not show up. I have just obtained a Cromemco 64KZ board. This has 64K of RAM and I'd like to test this out this weekend. Unfortunately, I don't have any documentation. There are 4 banks of RAM (16K x 8) Each bank is labeled "page0", "page1", "page2" and "page3". There are also 3 8-pin dip switches: I have a couple of photos at: http://www.msdsite.com/vcomp/cromemco/photos.html Since this is a 64K board and since there is other memory in my system. I'm hoping this allows some sort of bank switching. But without docs, I don't know how to use it. I assume the Bank A/B allow setting which bank a particular 16K might reside but am not sure. And the address lines of A15, A14 are a mystery. Is there a way to switch banks by writing to an I/O port? Location? Can any of you help with an explanation how this works and how I might use the switches?
