A good goal for you would be to get everything working under RT-11. That's a great way to learn. BTW, if you don't have a bootable 3rd party controller, or the DEC board with the boot ROMs, I hope you've figured out how to send the bootstrap over a serial line from a PC (I never did). Zane I did. I used to boot my 11/34 from RL02's with a 386 PC running Procomm. I believe I put the code in just a basic ASCII text file one line at a time with a carriage return after each and then uploaded the file as text over the same serial console line. Worked like a champ, and it sure saved the fingers from pressing those little chicklet keys on the programmers console...

OT: DSL and Apple Network Servers

by ckaiser＠oa.ptloma.edu

This is probably OT, so flames to my address. I finally tracked down a source of upgrades for my Apple Network Server 500. It will shortly be upgraded to 80MB RAM, and I'm mulling over buying a new processor card for it ($200! cough). MacWorks has some stuff in stock. So, with this buff discontinued box, I'm thinking of getting it a DSL line to boot. But I can't find a straight answer if all DSL services give you a static IP address or not. Do they? And should most of them work with AIX 4.1.4? I would think so, since it's just a DSL router and the ANS500 plugs into that like any other network. Thanks, sorry for the off-topic.

by wilson＠dbit.dbit.com

Mine just arrived this morning, I had ordered it from Netpliance's own 800 # so evidently at least *they* still have stock even if CC doesn't (suits me, the nearest CC is 1.5 hours away from me anyway). In keeping with nerd tradition I've got the thing all in pieces before even powering it on for the first time -- boy they sure didn't skimp on screws! But the 44-pin connector is right there as promised. I'm thinking of maybe doing a tiny PCB rather than soldering 44 individual wires on, I wonder if there's a +12V source in hear anywhere so that standard 40-pin IDE drives could be used too and not just laptop drives? The case is *really* cramped though. John Wilson D Bit

Almost free 2-port and 4-port fanouts, IEEE 802.3 compliant, Ethernet Version 1.0 and 2.0 compatible AUIs

by whdawson＠mlynk.com

Hello again, Well, due to the overwhelming response for these 2-port and 4-port Ehernet fanouts (actually, none) I'm posting this one more time. Since each of these weigh less than a pound packaged for shipping, your total cost for one to three is only $4.80, delivered in the US I will send these internationally, but the cost will be higher. The current list price on the two port units is $80.00+, and the 4 port units go for $200.00+. If there is no interest by tomorrow morning, I'll be listing them on eBay. Perhaps someone can tell me, on list, why no one on this list has any interest in these. Maybe everyone is saving their money for iOpeners d8^) ??? Thanks, Bill whdawson(a)mlynk.com -> Hello group, -> -> These were given to me recently by another member of this list -> who also has -> no use for them (thanks, Pat).

No. The earliest PETS almost all used the MCS6550 SRAMs I mentioned; a few used 2114s (different and fairly rare PCB). The later ones all used 4116s. None of them ever used 2101s or 2102s. I'm looking for a MCS6550; nothing else will do :-) -- Pete Peter Turnbull Dept. of Computer Science University of York

GRiD stuff

by mrbill＠mrbill.net

I've got a GRIDcase 1530 here, with no power supply. I tried using one of the cheap 9.95 "multi-voltage, multi-attachment" generic power supplies I have here (use it to charge my mavica battery). Power supply's max is 12V. The GRiD says 16V, but someone told me they'll run off of 12V (automotive voltage) too. When I plug it in and hit the switch, the status lights above the keyboard flash on and off rapidly (continuously) in conjunction with a "ticking" noise. My guess is, the power supply isnt up to snuff with what the laptop wants. Anybody got a power supply (and/or an entire system WITH power supply) for a 1530 for sale? In fact, I'd be interested in ANY GRiD hardware that anybody on this list has for sale.

Mos Technology RAM wanted

by edick＠idcomm.com

I'm not at all sure what you've said here, Allison. Aren't we in agreement? The 2101 was a 1k-bit sram organized as 256x4 with separate inputs and outputs. The 2102 was a 1k-bit sram organized as 1kx1 with separate in and out. The 2112 was a 1 k-bit sram organized as 256x4 with common ins and outs. They're all different, but whoever wrote the message to which I attached mine already knew that it was a 256x4 in a 22 pin package 0.400" wide. Additionally, there was a 2115 which was a high-speed (25 ns) 1kx1 sram with open drain outputs. I saw few applications for that one, however. It had a cousin, the 2125, which had the same pinout and architecture, but had tristate outputs. Things got muddled when the iNTEL folks started using unused numbers in the 1K-bit family, e.g. 2114, for memories larger than 1k-bits. The 2114, however, was just a microcomputer-compatible (slow) version of the already widely used 2148/49, which was a fast (35-70ns) equivalent to the 2114. They also made the 2147 which had the same bit count as the 2148/49 but with a 4kx1 organization with separate input and output and pinout compatible with the much slower TMS4044. The PET 2001 was pretty early among the production microcomputers, hence may have come along too early to capitalize on the high-volume production of the 4K-bit srams.

I'm not certain I know which of the items on my list you're referring to , but I've learned that I have only five drives to deal with, so I'm not worrying about making a board at this juncture. I've got to adapt from two fairly standard connectors, i.e. 40-pin IDE and +12, 2x GND, +5, of which the +12 isn't needed, to that 44-pin connector on the notebook drives. The best arrangement I've seen is is a dual-row by 22 with short soldertails sticking strainght out from the connector in such a way as to facilitate soldering to a 2-sided PCB. That, at this point would work for me. I have an adapter between the two connector types but that's just a mite too large for my application, particularly since it restricts my ability to mount the drive such that it's centered on the PCB, half protruding through the top of the board and half through the bottom so as to avoid interference with the adjacent cards. So, John, did you find they were back-ordered on the ribbon cable? Since I'm in no hurry, perhaps it doesn't make much difference. You're right about the suitability of 50-conductor ribbon, though.

I think the basic number you're looking for is "2101" from the same 1K series as the famous "2102" which is a 16-pin 1kx1 with separate in and out. The 2101's I have are not fast enough to meet the 200ns spec. However, not much of anything that was readily available at the time the PET model 2001 came out was that fast. Either it was quite a bit faster, e.g. 2147, 2115, etc, or it was slower, e.g. 2114, 21L02, TMS4044 etc, which were typically 450 ns at that point in time. Those 450 ns parts worked handsomely with the 1 MHz 6502. Perhaps you'd be able to use a 2101. Let me know if you think that might work for you. I've had my small supply (maybe 4 pieces) since back in '76-'77 when I got my original 6501, though I've never used them for anything.
